Understanding White Label (WL) vs. Public Node (PN) Delegations with Chorus One

At Chorus One, we offer tailored staking solutions for various needs, including White Label (WL) and Public Node (PN) delegations.

Both options provide secure and reliable staking services, but each is designed for specific use cases. Below, we will cover the key differences to help you decide which solution aligns best with your staking objectives.

White Label Delegations

Overview

White Label delegations provide you with your own custom validator. This brings a host of benefits such as privacy, personal branding, geo-fencing, control of the commission rate, optional governance participation, and the ability to provide a validator service for your customer base if needed.

Key Benefits of White Label Delegations:

Exclusive Branding and Control

• Clients can brand and market each WL validator as their own staking service, creating a tailored experience for their audience. Alternatively, clients can keep the validators private for an anonymous service.

Complete Commission Fee Control

• You can set and manage fee structures and reward distributions to meet your specific objectives, ensuring maximum flexibility and alignment with your business model.

Direct Governance Participation

• With your own validator, you can choose to engage in network governance directly, casting votes and influencing protocol decisions as a unique entity. However, if you would prefer to not participate or outsource this to Chorus One, that is completely fine.

Security and Reliability

• White Label delegations benefit from Chorus One’s secure and resilient infrastructure, ensuring reliable performance and robust security for all delegators.

Enhanced Privacy

• With White Label validators, you minimize potential attack vectors since they aren’t shared with other clients or involve commingling of funds. Additionally, geographical region selection allows for optimized privacy and regulatory compliance.

Detailed Reporting

• For all White Label validators, Chorus One offers comprehensive reporting and support for all contracted customers. The cadence and granularity of the reporting can be tailored to your unique business needs.

Public Node Delegations

Overview

Public Node delegations allow multiple clients to delegate to publicly accessible Chorus One validator nodes, optimizing for accessibility and simplicity. For those staking a large amount, please discuss with our Sales Team whether more favorable commission rates may be available for your delegation.

Key Benefits of Public Node (PN) Delegations:

Efficient and Accessible Staking

• Public Node delegations offer a user-friendly way to stake without the complexities of setting up a dedicated validator. Clients can delegate their assets and start earning rewards through Chorus One’s infrastructure immediately from a supported custodian or self custodial solution.

• There are no token minimums to begin staking.

Lower Operational Costs

• By utilizing and existing node managed by Chorus One, Public Node delegations reduce the complexity of staking, making this solution ideal for clients who prioritize simplicity and the ability to hit the ground running.

Security and Reliability

• Public Node delegations benefit from Chorus One’s secure and resilient infrastructure, ensuring reliable performance and robust security for all delegators.

Participate in Governance

• While Public Node delegators do not participate directly in governance, Chorus One acts as an active, informed participant, ensuring our node supports the best interests, security, and scalability of the network.

Detailed Reporting

• For all Chorus One customers whether White Label or Public Node, Chorus One offers comprehensive reporting and support for all contracted customers. The cadence and granularity of the reporting can be tailored to your unique business needs.

Summary of Key Differences

Which Solution Is Right for You?

If you’re an institution, high-net-worth individual, or enterprise looking for branded staking, control over settings, privacy, customizability, or the ability to provide staking services to your customer base, then a White Label (WL) validator may be right for you.

If you seek an accessible staking solution with a low barrier to entry and reliable returns all backed by Chorus One's robust security model and do not have a unique need for validator-specific settings, then choosing a Public Node (PN) delegation might be most suitable.

Staking Terms & Terminology

While we covered the overall gist of how staking works in our Staking Overview, there are many nuances and different concepts in the world of staking that vary from network to network.

Delegated Proof of Stake (DPoS)

A consensus mechanism where token holders delegate their staking power to validators who participate in network consensus on their behalf.

Examples:

• Networks like Tezos and use DPoS among many others that use either DPoS directly or a combination of this consensus model with new novel models.

Benefits:

• Greater scalability and efficiency compared to traditional Proof of Stake (PoS).

• Lower barrier to entry for token holders who want to participate in staking.

Staking as a Service (SaaS)

This is one of the many services Chorus One offers. SaaS involves a trusted third party solution that simplifies the staking process for users or institutions, typically by managing validator infrastructure.

Example:

• Chorus One offers staking services for multiple networks, ensuring secure and reliable validator operations.

Benefits:

• Reduces technical complexity for stakers.

• Provides institutional-grade reliability.

• Allows White Label branding and dedicated support for all your staking needs.

• Comprehensive rewards reporting directly from Chorus One or via

Slashing

A penalty imposed on validators (and their delegators) for misbehavior, such as downtime or double-signing blocks. It is the punishment mechanism to ensure and incentivize good behavior on a network for all participants and helps keep the network secure.

Auto-Compounding Staking Rewards

A mechanism that automatically reinvests staking rewards into the staked principal, allowing users to earn compound interest without manual intervention.

Benefits:

• Auto-compounding maximizes yield without additional effort for the user.

• This can make networks with this mechanic ideal for long-term stakers.

Staking Pools

Staking Pools use a collective staking approach where multiple users combine their tokens to meet the minimum requirements for staking to create accessibility for users who otherwise could not participate and to increase reward efficiency.

Examples:

• — By pooling ETH in a custom solution, Chorus One has created an Ethereum staking solution that allows any user to stake any amount of ETH instead of being limited to quantities of 32 ETH.

• has a high requirement to stake. By using a STX pool run by Chorus One, users with lower amounts of STX can participate and earn rewards.

Benefits:

• Accessibility for for more users leading to more equitable access to rewards potential.

• Increased network decentralization.

Proof of Liquidity (PoL)

A staking mechanism that locks liquidity-providing tokens (e.g., LP tokens) in return for network rewards, aligning staking with liquidity provisioning.

Example:

• Berachain’s PoL mechanism locks LP tokens in exchange for staking rewards, creating incentives for deep liquidity in its ecosystem.

Benefits:

• Encourages liquidity in trading pairs.

• Dual rewards from staking and trading fees.

Staked Assets are Locked Right? Not with Liquid Staking!

When assets are staked, they generally can’t be used for other things. This creates some capital inefficiency.

How Does it Work?

Liquid staking generally works by creating a smart contract that pools the stakeable asset.

The smart contract then stakes these assets with various providers.

The delegator receives a token that represents a claim on the staked assets. This is a token that can be used and transferred without limitations, opening up new possibilities to leverage your staked assets.

What are the Advantages of Liquid Staking?

Liquid staking allows quite a few benefits such as:

• Selling the staked asset instantly without going through an unbonding or unstaking period.

• Use the asset as collateral to borrow against it.

• Providing the staked asset as liquidity in exchanges and earning trading fees as well as staking rewards at the same time.

These are only a few examples of what LSTs can do. There are a variety of DeFi platforms out there where users can get creative with how to maximize the utility of their staked assets.

A brief introduction to StakeWise v3

Jordan Sutcliffe, Head of Business Development at Stakewise, aptly coined StakeWise V3 as the ‘Swiss army knife’ for ETH staking, sparking a flurry of interest from ETH enthusiasts. During the unveiling, the team revealed that the new version opens the doors for anyone capable of running Ethereum validators to engage in liquid staking and receive delegations in a permissionless manner.

This is an approach that aims to welcome a broader range of participants, fostering control and driving decentralization within the Ethereum staking ecosystem.

StakeWise V3 achieves this by introducing the concept of layered staking, allowing users to:

1. Delegate ETH to a vault of the node operator(s) of their liking (1st layer)

2. Giving them the option to mint osETH to represent their stake (2nd layer)

This design enables anyone to join as a solo staker who can mint osETH tokens against their node, or delegate ETH across multiple nodes to counteract network concentration.

Notably, StakeWise v3 introduces a slashing-resistant staked ETH token, osETH, ensuring scalability without introducing systemic risk to the broader ecosystem.

The current state of Ethereum Staking, and why it had previously been an exclusive club

Ethereum was conceived with the mission of building a permissionless, censorship-resistant and financially robust network for value exchange.

The transition to Proof of Stake (PoS) through the Merge aimed to democratize participation, shedding the hardware and compute costs of Proof of Work (PoW). A year on from the Merge, however, centralization remains one of Ethereum’s biggest challenges - ironically, drifting towards the paradox of its own mission statement.

Staking on Ethereum had previously mandated validators to lock up 32 ETH with the network. While this investment yields interest, any misstep or dishonest conduct by a validator can lead to the revocation of funds. Setting up a validator node to stake on the network can also be a complicated task, meaning financial penalties can result if things are set up improperly.

This innovation democratized ETH staking, allowing nearly anyone to participate. Intermediaries assumed the operational responsibilities, handling the pooling, staking, and technical requirements, while taking a share of the rewards for their efforts.

Why StakeWise V3?

The drawback of the pre-existing version of StakeWise and its counterparts is simple but crucial.

The absence of technical or capital requirements, the ability to temporarily exit from staking, and the increased efficiency of staked capital presented by liquid staking protocols resonate with depositors to an extent that it leads to a decrease in solo stakers (for example, individuals setting up ETH validators at home).

Over time, this decline can significantly impact Ethereum’s security and decentralization.

To address this, the StakeWise DAO introduced StakeWise V3, its latest version that allows anyone from solo stakers to established node operators to financial institutions to participate.

As a solo staker, one can seamlessly launch their own nodes, mint staked ETH (osETH) tokens against their nodes, or delegate any amount of ETH across multiple nodes to counteract network concentration.‍

The key components of StakeWise V3: Vaults and the osETH Token

‍Layer 1: Vaults

At the heart of StakeWise V3 are ‘Vaults’ - a network of permissionless, non-custodial staking mini pools that anyone can launch on the and receive ETH delegations on their nodes.

StakeWise vaults offer the user freedom to stake with whichever vault they want, choosing between vaults run by solo stakers, node operator companies, and groups of solo/commercial operators.

For every 32 ETH of deposits accumulated in a Vault, the Vault operator(s) registers an Ethereum validator in the Beacon Chain and starts staking. The staking rewards belong to the depositors, net of the staking fee charged by the Vault.

Importantly, each of these Vaults is completely unique to the configurations set up by its operator, meaning that the operator can fully customize its vault as per its own design, allowing users to pick a vault based on the features that best suit the depositor.

Essentially, Vaults are completely agnostic to the staking solutions that an operator wants to run - whatever client solutions, KYC features, MEV relays or DVT middleware that the entity wants to run are under their control.

This leads to a very diverse marketplace of staking solutions that users can shop around and choose from.

Moreover, Vault Operators can set their Vault to a private setting, allowing deposits only from addresses whitelisted by the Vault Operator.

This enables use cases like solo stakers depositing ETH into their own Vault and not accepting deposits from others. For instance, compliance-sensitive organizations can create a Vault to enable staking for only a limited number of KYC'd participants.

Layer 2: The osETH Token

The osETH Token is a new type of overcollateralized ETH token introduced by v3, which is a liquid ERC-20 representation of staked assets that uses Vault Token(s) as collateral. It can be minted by anyone who has staked ETH into a Vault(s), or can be bought/sold on decentralized exchanges.

Importantly, osETH represents a new type of liquid-staked ETH token that has its value pegged to staked ETH 1:1, but that does not directly pass on the slashing losses to holders, ensuring that all the staking rewards and penalties remain isolated to the individual Vault.

To ensure this, V3 requires >1 ETH for every osETH that stakers in a Vault want to mint.

In the scenario where slashing does occur, there is always a reserve of ETH that absorbs the slashing losses before osETH holders are affected. This protects osETH holders from losing their principal, making osETH a safer option for staking.

Note that the stakers who mint osETH are of the Vaults in which they staked ETH, and excess collateralization makes sure that the other osETH holders are not affected.

The Use Cases of StakeWise

Why Stake?

Staking offers a way for institutions and individual investors to earn rewards on their assets while still maintaining full custody of them.

Whether you're an individual investor seeking to make your assets work for you, or an institution managing a crypto treasury or providing services to clients, staking is the ideal solution.

Below, let's dive into why staking is the most important and reliable source of yield in crypto.

Or, if you prefer, you can review some information packets in the tabs below.

What is Staking and Proof of Stake?

Let's look at a big picture conceptual overview of staking. While the finer nuances and details of the exact mechanics can vary from network to network, the core concept of Proof of Stake (otherwise referred to as PoS is generally quite similar between networks).

In a nutshell, non-custodial staking can be thought of as nearly the equivalent of depositing funds in a high yield savings account, however, with four main differences.

1. You retain control of your assets and your stake remains in your custody.

2. The base value of the asset you're staking can increase or decrease in price.

3. The rewards you accrue from staking are generally in the native token you staked, however, for some networks there are exceptions.

4. By staking, you are contributing to the overall security of the network though a mechanism known as Proof of Stake.

So How Does it Work?

Staking means that holders of a specific token (the staking token) provide the token as collateral vouching for the correct and honest behavior of the validator that they delegate (stake) to.

When you stake, it involves locking away the assets in a non-custodial manner to incentivize network participants and validators to not act dishonestly. This in turn increases the security of the network via the validators, which are nodes on the network which receive the stake and verify transactions and ensure that the ledger (blockchain) is accurate and continues to move forward.

The Role of the Validator

The validator is responsible for processing and verifying transactions, producing blocks and securing the blockchain, thus reaching consensus. Chorus One specializes in running validators on many different Proof of Stake networks. Ensuring you stake to a reputable validator not only helps ensure the safety of your funds but also contributes to the health and security of the network.

In return validating the network, the validator earns rewards for contributing to the overall network security and moving the blockchain forward. Thus, they earn staking rewards which are distributed to the stakers (delegators) to that validator.

This is how staking earns passive rewards on the funds you stake (delegate) to a validator. PoS (Proof of Stake) blockchains generally pay inflationary rewards as well as transaction fees as staking rewards.

What are Consensus Mechanisms?

The two main consensus mechanisms are Proof-of-Work (PoW) used by Bitcoin and other networks, and Proof of Stake (PoS), used by Ethereum, Solana, Cosmos, Avalanche, among others.

• Proof of Work (PoW): Miners compete to solve complex math problems using powerful computers. The first to solve the problem gets to add a new block to the blockchain and earn rewards. This process uses a lot of electricity and computing power. Bitcoin uses PoW.

• Proof of Stake (PoS): Validators are chosen to add new blocks based on how many delegated assets they hold and are willing to "stake" as collateral. The greater number of assets you stake, the higher your chances of being chosen to validate the next block. This method is more energy-efficient.

Is Staking Safe?

Staking is not the only way to earn rewards in crypto, however, it is by far one of the safest.

Let's look at some of the perks outlined below.

Introduction

Maintaining strong crypto security requires diligence across both custodial and non-custodial wallet storage methods. Below we will cover some good general practices to follow and then dive into aspects unique to both non-custodial and custodial platforms.

Feel free to jump ahead to the sections that are most relevant to you.

• General Best Practices

General Best Practices

Enable Two-Factor Authentication (2FA)

• Always activate 2FA (authenticator apps or hardware keys) for added account security when supported. Application or hardware based 2FA is more secure than SMS (text message) 2FA.

Use Strong, Unique Passwords

• Create complex passwords that are unique to your wallet or account. Store them securely in a password manager.

Beware of Phishing Scams

• Double-check URLs and avoid clicking on suspicious links or downloading unverified software. Only interact with trusted wallet providers.

• If in doubt, run a link or file through before clicking or opening it.

Secure Your Devices

• Keep your smartphone, computer, or hardware wallet updated with the latest security patches and antivirus software.

Avoid Public Wi-Fi Whenever Possible

• If you must use public Wi-Fi, ensure you are connected through a reliable VPN to encrypt your connection.

Be Mindful of Social Engineering Attacks

• Scammers may impersonate wallet providers or support staff. Never share sensitive details, especially your seed phrase or private keys.

• When in doubt, contact the person or company through their official communication channels to verify authenticity.

Verify Transactions Carefully

• Double-check wallet addresses and amounts before confirming any transaction, as blockchain transactions are irreversible.

Best Practices for Non-Custodial Wallets

Protect Your Seed Phrase

• Write your seed phrase on paper (not stored digitally) and keep copies in separate, secure locations. Avoid taking pictures or saving it online. There are even options to store your seed phrase on steel plates.

  • See also:

Use Hardware Wallets for Long-Term Storage

• For significant holdings, a hardware wallet provides the highest level of security by keeping private keys offline.

• Multi-Sig setups are also an option in some cases, however, please contact us if you are using a Multi-Sig solution for your staking needs to ensure compatibility with the intended network.

Backups Are Critical

• It is ideal to keep multiple copies of your seed phrase secured physically (i.e. never stored as a screenshot or digital file) and kept in geographically dispersed locations if possible.

• If you're new to crypto, try creating a new empty wallet and restoring it to get a sense for how wallet recovery works via the wallet's seed phrase.

Separate Wallets for Different Uses

• Depending on your use cases and unique situation, it can sometimes be strategic to use a hot wallet for daily transactions and a cold wallet (offline and/or a hardware wallet) for long-term storage.

Verify Wallet Authenticity

• Download wallet software only from official sources to avoid malware or counterfeit apps.

• This also applies to buying hardware wallets directly from the manufacturer. It is not advisable to purchase a used hardware wallet.

Best Practices for Custodial Wallets

Choose a Reputable Provider

• Use custodial wallets or exchanges with a strong security track record, regulatory compliance, and robust features that fits your needs.

Monitor Account Activity

• Regularly review login attempts and transaction history for any suspicious activity.

• If applicable, consult with your custodial account manager to set up their own best security practices for your account.

Enable Withdrawal Whitelisting

• Some custodial wallets let you whitelist addresses, ensuring funds can only be withdrawn to specific, trusted addresses.

Stay Updated on Platform Changes

• Be aware of announcements from your custodial wallet provider about updates, security breaches, or policy changes.

Questions?

Feel free to reach out to our Support Team if you would like any clarification or if you encounter anyone or anything impersonating Chorus One.

• Chorus One:

What is Arbitrum?

Arbitrum is a Layer 2 scaling solution for Ethereum that enhances transaction speed and reduces costs by processing transactions off-chain, while still leveraging the security of Ethereum's blockchain.

It uses a technology called Optimistic Rollups, which bundles multiple transactions together and submits them as a single batch to the Ethereum mainnet. This allows users to enjoy faster and cheaper transactions for decentralized applications (dApps), without sacrificing the decentralized security provided by Ethereum.

What is Bridging?

Bridging to Arbitrum involves transferring assets from a Layer 1 blockchain, like Ethereum, to Arbitrum, a Layer 2 scaling solution. The process requires users to interact with a bridge interface where they connect their wallet (such as MetaMask), select the token they wish to transfer, and approve the transaction. The tokens are then locked on the Layer 1 chain and represented as wrapped tokens on Arbitrum.

How to Bridge to Arbitrum

1.) Navigate to the Arbitrum Bridge

First, navigate to the Arbitrum bridge website found here:

Once you have navigated to the Arbitrum bridging website, you can connect a compatible wallet.

For this guide, we will be using .

• If you don't yet have a MetaMask wallet, please follow the official guide from MetaMask to get started and set up your new wallet:

• While MetaMask is compatible with many browsers, Chromium based browsers such as Google Chrome or Brave tend to have the best compatibility across various dApps.

2.) Connect your Wallet

Once your MetaMask or other compatible wallet is ready, connect to the Arbitrum bridge when prompted, or click on the green button in the upper-right hand corner that reads 'Connect Wallet'.

• If you are prompted, or need help connecting your MetaMask wallet to the Arbitrum network, please see the following section:

After connecting your wallet, the bridge page will default to the Ethereum (ETH) asset.

• It is advisable to first bridge some ETH to Arbitrum if you don't have any already, as it will be needed to pay for all gas fees on the Arbitrum network.

• After this, you can bridge over any other compatible tokens you wish.

3.) Bridging your assets to Arbitrum

You'll see a screen similar to the screenshot below. This illustrates an example of bridging over some ETH to Arbitrum.

You can enter an amount of your choosing and see how much you will receive on Arbitrum as well as the expected gas fees involved with the transaction.

Go ahead and proceed once you have selected how much ETH you wish to bridge.

You will be prompted to sign the transaction via your MetaMask wallet (and Ledger) if you are using a hardware wallet.

4.) Bridging other tokens to Arbitrum

In addition to ETH, it is possible to bridge many other ERC20 tokens to Arbitrum.

You can select from the list to find what you want to bridge. In the example below, we will be using USDC.

Go ahead and approve the transaction in a similar fashion as you did for your ETH.

For some tokens, USDC being a great example of this, you will get to choose what version of the token you wish to receive on Arbitrum.

• For USDC, you can choose to bridge native USDC via the Arbitrum bridge or a third party bridge

• Alternatively, you can choose Wrapped USDC, known as USDC.e

Any of the options are fine, however, be sure to read the fine print on what the differences are between native and wrapped versions of your ERC20 tokens, as depending on your planned use case on Arbitrum, this differentiation may matter!

5.) Checking on the status of your bridged assets

After you've initiated some bridging transactions, you will likely be prompted to view your transaction history.

• It's worth noting that bridging assets to Arbitrum can take a few minutes depending on network conditions and the type of assets you are bridging.

6.) Connecting to the Arbitrum Network

If you haven't already added Arbitrum as a network to your MetaMask wallet, you will need to in order to interact with your Arbitrum assets.

The wallet may prompt you automatically, and if so, go ahead and proceed with those prompts.

If you are not prompted, you can add the Arbitrum Network to MetaMask via the following steps.

• Open your MetaMask browser wallet and click the network selection button.

Next, select Arbitrum if it appears in the list. If it does not, you can search for it via the search bar or click 'Add network' to manually enter the network information.

• Go ahead and follow the prompts to switch to and connect to the Arbitrum Network.

Chorus One Rewards API

The Chorus One Rewards API provides comprehensive access to staking rewards data across multiple blockchain networks. Built for Chorus One clients and partners, these APIs offer reward tracking with enterprise-grade reliability.

Staking

The Native Staking API aims to simplify the process of staking by providing a set of endpoints that users can use to generate the key material and the deposit data needed to stake on Ethereum.

The API documentation is available at API Reference and provides detailed information on the available endpoints and their usage.

Authentication

Every API request requires authentication via a bearer token in the X-API-TOKEN header. Once requested through the page, our team will provide you with a unique token for your tenant. To obtain a token, please provide the below in the request:

• Tenant name

• Tenant description to Chorus One representative.

Important: Store your API token securely. Lost tokens cannot be recovered by Chorus One, but we can generate new one upon request for you.

How to use the token in your requests:

Integration

1. Request a batch of validators with deposit data

Pre-requisites:

• An authentication token received from Chorus One

• A withdrawal address that you control

⛔️ Important: Losing access to the withdrawal address will result in losing access to the staked funds.

The process of depositing validators managed by Chorus is shown on a diagram.

An example request to create a batch of 10 validators on the Mainnet network:

📝 Note: Rate Limits & Quotas

• Each tenant receives a specific summary validator quota, for the total number of validators that can be created across all batches. This is intended as a sanity check, to protect against rogue automation creating millions of validators.

• Rate limiting prevents accidental quota exhaustion

• Contact Chorus One representative for quota increases

What happens on the backend:

• The request is validated and persisted in the database

• A separate process generates the key material and the deposit_data for every new batch of validators

• The deposit_data is saved in the database as it does not contain any sensitive information

What needs to happen on client side:

• Once new batch request have been created, API will return UUID that represents particular validators batch in Chorus One backend. Client must save this UUID and use it in further requests that concern newly generated validators. /batches endpoint can be used to retrieve UUIDs for all past requests.

2. Monitor status of the batch

Pre-requisites:

• An authentication token

• Previously saved UUID of the batch

An example request to get the status of the batch:

What happens on the backend:

• The request is validated and the status of the batch is retrieved from the database

• If all deposit_data has been generated, the status will be ready and the response will include the deposit_data for each validator. The status of the validators will be created awaiting the be deposited.

Validator status field in API output will update as follows:

• Initially validators show status as created after deposit_data generation

• Once deposited, activated on the network and starting to receive rewards, validators will show status as active

• Exited validators will show status as exited

3. Deposit the validators on the Ethereum network

For this, the user needs to:

• Extract the deposit_data for each validator.

• Use the deposit_data to deposit the validators on the Ethereum network:

  • using the the official

Upload the deposit_data-[timestamp].json file to the Ethereum Staking Launchpad and follow the instructions to complete the deposit.

• Using an audited batch deposit contract

Main risks and remediations:

• The withdrawal address must be secured and not treated as a hot wallet. Best practice is to use a multisig wallet contract for this purpose.

• The withdrawal address should be dedicated to the purpose of Ethereum staking.

Unstaking

Once a validator has been deposited on the Ethereum network, it will start earning rewards. However, there are situations where the user might want to stop validating and withdraw the funds. The earlist time a validator can be withdrawn is after 256 epochs, which is approximately 27 hours after the validator has been activated.

To unstake a validator, the user needs to provide an exit message for the validator. The exit message is a signed message that proves the ownership of the validator and is used to withdraw the funds. The exit message is generated by the Native Staking API and can be requested by providing the batch ID and the epoch number for which the exit message is needed. Once the validator has been exited, the funds will be sent to the withdrawal address provided during the staking process.

The process of exiting validators managed by Chorus is shown on a diagram.

Pre-requisites:

• An authentication token

• Previously saved UUID of the batch

• An epoch number for which the exit message is needed (optional, if not provided, the current epoch will be used)

• Access to an Ethereum beacon node API that supports voluntary exit endpoint described

Integration

1. Extract the deposit_data for each validator.

1. Call the endpoint of the Ethereum beacon node API to submit the exit message for the validator.

Note📝 Exiting a validator takes time and it depends on the network conditions, such as the churn limit which is the maximum number of validators that can exit in a single epoch.

1. Monitor progress of validator exit by visiting the and searching for the validator's public key, or using automated process that polls API of Ethereum beacon node for validator status progression.

2. Actual withdrawn funds will arrive to withdrawal address in few days after validator is exited.

Main risks and remediations:

• If someone gains access to your exit messages, they can force your validators to exit. While the funds will remain secure and will be sent to the withdrawal address, you risk losing potential staking rewards. This is significant because withdrawing existing validators and activating new ones is a time-consuming process.

Key Information

• Chorus One pool address: SP2A2HGHMS3EQYRS8E0ACQ64DMS3P6C57A6VBE45V

• You do not transfer ownership of assets to the pool. With delegations, your stacked tokens remain in your wallet for the entire duration.

• A stacking cycle occurs every 2100 Bitcoin blocks are mined. This takes approximately two weeks and varies depending on network conditions. The tokens are locked for the entire rewards cycle.

What is Stacks

Stacks utilizes Bitcoin's Proof of Work (PoW) consensus mechanism to secure its own blockchain layer that enables smart contracts and decentralized applications (dApps) to be built on top of Bitcoin.

Specifically, Stacks is a novel layer built on top of Bitcoin that introduces smart contract and dApp functionality without altering Bitcoin's core protocol. This integration is achieved through Stacks' Proof of Transfer (PoX) consensus mechanism, which reuses Bitcoin's PoW to secure the Stacks network.

By leveraging Bitcoin's PoW security model, Stacks aims to extend the utility of Bitcoin, the most decentralized and secure blockchain, by enabling smart contracts that can directly interact with Bitcoin's state and transactions. This allows Stacks to facilitate the growth of the Bitcoin economy by turning BTC into a productive asset and enabling a wide array of decentralized applications.

While Stacks has its own global ledger and execution environment for smart contracts to avoid overwhelming the Bitcoin blockchain, it secures this parallel layer by reusing Bitcoin's PoW consensus, providing a novel solution to the challenges of developing smart contracts on Bitcoin's base layer.

Why should you stack STX?

Stacking is locking your STX temporarily to support the Stacks blockchain’s security and consensus mechanism. As a reward, you earn Bitcoin that miners transfer to you as part of Proof of Transfer mining. In the same way that Bitcoin miners run mining software to support the Bitcoin blockchain and earn BTC, you can support the Stacks blockchain and earn BTC just by buying and locking up STX tokens.

How to stack STX with Chorus One?

1. Visit lockstacks.com and connect using one of the supported wallets

2. Click on "Stack in a pool"

3. Select "Custom Pool" and enter this address:

4. Type in the amount you want to stack

5. Pick the duration of the delegation.

We recommend indefinite permission (you can revoke it at any time), but you can also pick "Limited permission" for any duration between 1 (~2 weeks) and 12 (~5-6 months) cycles.

6. Click on "Confirm and pool" and sign the transaction.

After confirming, you will be redirected to the .

It might take a while for your delegation to show up there. It takes a few minutes usually, but sometimes it can take up to 2 hours or longer.

You might see an error message: "Error while loading data, try reloading the page." during this period.

7. Please send us the stack address that you delegated from and the BTC address for rewards.

The rewards will be paid at the end of every cycle.

How to Undelegate your stacked STX?

1. Visit and click on "Stop pooling"

2. Confirm using the connected wallet

3. Your tokens will unlock at the end of the current rewards cycle and Chorus One will no longer be able to lock them for the next cycles.

How to increase your delegated STX amount?

In order to increase the delegated stacking amount on Stacks, you need to first undelegate the original funds and make a new delegation with the new amount.

Ideally this should be done during the unlock phase at the end of the current cycle.

1. Visit and click on "Increase pooling amount".

You should see this message:

"To increase the amount of STX you must first stop the current pool and start pooling again, your pool operator can then lock a higher amount for the next cycles."

2. Click on "I understand I want to stop pooling" and confirm the transaction

3. Go through the steps in "How to stake STX with Chorus One" again with the new stacking amount.

You can skip the last step in these instructions if your stacks and rewards addresses remain unchanged.
