EigenLayer, Symbiotic, Obol DVT, Mellow, and osETH
Liquid staking enables token holders to stake their cryptocurrency while also receiving a representative token (for Chorus One; osETH) that can be used in DeFi applications to earn additional APR on their staked ETH.
osETH is over-collateralized, reducing risk for the staker.
Chorus One's pioneering MEV research led to the design of Adagio an in-house, optimized Ethereum MEV-boost client that increases our MEV rewards by optimizing the way we interact with the transaction supply chain.
This ensures that our customers receive optimal MEV yields consistently, rather than solely during periods of high volatility or rare occurrences.
In adherence to transparency principles, our research is entirely accessible to the public on EthResearch.
