Ethena (ethena)

​

What it offers

• stakeUSDe: Stake USDe to receive sUSDe (yield-bearing)
• cooldownAssets: Start cooldown period to unstake (by asset amount)
• cooldownShares: Start cooldown period to unstake (by share amount)
• unstake: Complete unstake after cooldown period

​

Notes

• Yield comes from ETH staking rewards + perpetual funding rates
• 7-day cooldown period required before unstaking
• Flow: deposit (stake) -> cooldownAssets/cooldownShares (start cooldown) -> unstake (after 7 days)
• Approve USDe to sUSDe contract before depositing
• sUSDe appreciates against USDe as yield accrues
