The vaults convert Aave’s variable lending rates into fixed yields that wallets, exchanges and payment apps can offer their own users.
Aave Labs launched Stable Vaults on Thursday, infrastructure that lets fintechs, wallets, exchanges and payment providers embed fixed-rate stablecoin yield into their own products, the company said in a blog post.
The vaults convert variable onchain lending rates, drawn from Aave V3 and V4 markets or other ERC-4626 strategies, into a fixed rate a business sets for its end users. Aave Labs handles the rebalancing and cross-chain operations in between, according to the blog post.
Already Live in Aave’s Own App
Stable Vaults are “the smart contract vaults that already power the Aave mobile savings app,” per the post, and are now open for any business to build on. Aave, the largest DeFi lending protocol with $12.80 billion in total value locked, said Chainlink Price Feeds and CCIP can support any Stable Vaults deployment and will power its own app’s production version.
Aave founder and CEO Stani Kulechov said on X the product offers “fixed yield, cross-chain access, multi-strategy allocation, tier-based rates, and more,” and is “now available to businesses looking to offer stablecoin yield to their users.”
What Operators Control
Businesses choose which stablecoins to accept, which yield strategies to use, and what fixed rate to offer each user, according to the blog post. Any yield the underlying strategy earns above the promised rate goes to the vault operator as revenue, letting the product function as an on-chain fixed-income model rather than a pass-through of Aave’s floating rates.
Aave cited possible use cases including a neobank embedding savings powered by Aave markets, a payments company earning on idle settlement balances, and a wallet or exchange adding a one-tap earn feature backed by Savings GHO.
The launch follows Aave’s October acquisition of Stable Finance and a March proposal for a GHO-based savings product, part of a broader push to bring DeFi yield to mainstream consumer apps.
