According to Mike Silagadze on Twitter, the recent $ETHFI buyback last week would have resulted in an effective APR of over 120% for stakers, but the protocol has implemented a cap at 35% to maintain stability and smooth returns over time (source: @MikeSilagadze, May 13, 2025). This capped 35% APR is likely to remain sustainable in the near term, depending on continued staking participation. For traders, this signals strong yield opportunities and could incentivize further capital inflow into $ETHFI, impacting token price action and liquidity in the wider DeFi and crypto markets (source: ether.fi/app/ethfi).
