What is Yelay?

Yelay is a yield infrastructure protocol formerly known as Spool that helps DeFi apps, wallets, and treasuries plug yield into any product. Builders deploy Smart Vaults via the Yelay SDK, and user deposits are auto-routed across more than 90 strategies on Ethereum and Base, with rebalancing, auto-compounding, and reward swaps handled in the background. The protocol has routed around $320M lifetime.
