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. sGHO uses the ERC-4626 tokenized vault standard, which is widely supported across decentralized finance, meaning lending markets, yield aggregators, centralized finance platforms, and other applications that already work with ERC-4626 vaults can integrate sGHO without custom development.
