Aave has launched a new version of its GHO savings product, replacing legacy stkGHO with sGHO, an ERC-4626 vault that offers a fixed 4.25% annual percentage rate, with the announcement shared on May 18. The upgrade introduces a standardized vault structure, a predictable savings rate, and a new routing system designed to simplify deposits into the protocol's native stablecoin savings product. The new sGHO vault allows users to deposit GHO and earn yield that accrues automatically through the vault's share price, whereas under the previous stkGHO model, rewards were distributed separately and often required users to claim them manually through Merkl.
