ether.fi (etherfi)

​

What it offers

• deposit: Stake ETH and receive eETH
• wrap: Wrap eETH into weETH (non-rebasing)
• unwrap: Unwrap weETH back to eETH

​

Notes

• Liquid restaking protocol
• eETH rebases like stETH. Use weETH for DeFi (Aave, Pendle, etc.)
• deposit() is payable - send ETH as msg.value
• Approve eETH to weETH contract before wrapping
• Natively restaked on EigenLayer for additional AVS yield
