# Ribbon Earn stETH

Ribbon Earn stETH uses the 0.5% of deposited funds as well as the yield generated from staking ETH onLido to fund exotic options and enhance the yield earned on stETH. So the vault employs a fully funded [dolphin strategy](/ribbon-earn/ribbon-earn-steth/what-is-a-dolphin-strategy.md) through which depositors can capitalise on the upside ETH movements while also ensuring their capital is protected up to 99.5% per trade. 

The name "dolphin" (or "sharkfin") comes from the shape of the vault yield curve, that of a "[dolphin's fin](/ribbon-earn/ribbon-earn-steth/what-is-a-dolphin-strategy.md)".
