Custodial versus Self-Custodial Wallets
A brief overview of different ways your crypto can be stored.
Custodial versus Self-Custodial Wallets
The key difference between custodial and non-custodial wallets lies in who controls the private keys. Custodial wallets are managed by a third party (e.g., qualified custodians or exchanges), which hold your private keys and secure your funds. Self-custodial wallets give you full control of your private keys and assets, making you solely responsible for their security.
While that might make self-custodial wallets sound intimidating with proper security measures you can rest assured your funds are safe.

Custodial Wallets & Exchanges
A custodial wallet is a type of cryptocurrency wallet where a third party, such as an exchange or service provider, or qualified custodian manages the private keys on your behalf.
This means the provider holds full control over your funds, and you rely on them to secure your assets and enable transactions. Users typically access custodial wallets via a username, password, and potentially additional security measures like two-factor authentication (2FA).
Key Features:
Ease of Use: Custodial wallets are beginner-friendly and offer integrated services like buying, selling, and trading directly within the platform.
No Private Key Management: You don’t need to manage private keys, reducing complexity but requiring trust in the custodian.
Centralized Control: The custodian has control over your funds and can freeze accounts or impose withdrawal limits under suspicious circumstances.
Regulatory Compliance: Your business needs may require the use of a qualified custodian.
Self-Custodial Wallets
A self-custodial wallet gives users full control of their private keys and, by extension, their funds.
These wallets do not involve a third party, meaning you are solely responsible for managing and securing your keys. Self-custodial wallets can be software-based (mobile or desktop apps) or hardware devices (known as hardware wallets) designed to store private keys offline.
Key Features:
Full Control: You are the sole custodian of your funds, with no reliance on third parties.
Private Key Ownership: The wallet generates and stores private keys locally, often represented by a seed phrase for backup.
Decentralized: Self-custodial wallets align with the principles of decentralization, granting autonomy to users.
Integration with dApps: While often possible with custodial solutions, self-custodial wallets are often more readily able to interface with dApps (decentralized applications) in the Web3 ecosystem.
Key Differences
Ownership: Custodial wallets involve a third party holding your keys; self-custodial wallets grant you full ownership of your keys.
Risk Profiles: Custodial wallets carry the risk of hacks or freezes due to centralized management. Self-custodial wallets place the responsibility of security on the user.
Regulatory Compliance: Custodial wallets are sometimes required for regulatory compliance based on your unique business needs.
