Chainlink has launched ETH Staking APR Feeds to provide a reliable on-chain reference for Ethereum staking rates, supporting innovation and experimentation in the staking ecosystem. These feeds serve as a trust-minimized and tamper-proof source of truth for the global rate of return from staking as a validator, leveraging Chainlink's established Data Feeds infrastructure. By offering this baseline measure, Chainlink aims to facilitate better risk assessment for validators, enable users to explore diverse financial strategies, and empower builders to create novel on-chain financial products. The feeds calculate the net returns for each epoch by compiling data from both the consensus and execution layers, excluding exogenous yield sources like MEV payments to maintain accuracy. This approach distinguishes Chainlink's feeds from self-reported yield estimates by staking pools, providing a more precise benchmark for the Ethereum staking rate. The rate of return is measured over 30-day and 90-day rolling timeframes, with annualized percentages reported to the decentralized oracle network. Chainlink plans to expand its offerings to include additional feeds that encompass other yield sources in the future.
