Yelay V3 Review 2026: Yield Infrastructure for Stables and BTC

Yelay describes itself as yield infrastructure for stablecoins, Bitcoin and real-world assets. Rather than being only a consumer app, it offers vaults that other platforms can embed through an SDK or launch under their own brand.

The homepage claims more than $370M routed since inception, over 100 active strategies and five liquidity venues. DefiLlama files Yelay V3 as a yield aggregator on Sonic, Ethereum and Base, with a listing date in May 2025 and a current TVL of about $62.8K.

Its flagship retail-facing product is DeFi Blue Chip, a USDC vault with a stated historical APY of 6-9%, no minimum and immediate liquidity. Other products are aimed at institutions, including high-minimum RWA vaults and BTC collateral structures. A higher-yield Pendle strategy is listed as coming soon.

The project has a token, YLAY, which has seen sharp price moves according to search snippets.

Yelay works as a vault layer. A user deposits an asset such as USDC into a vault, and the vault splits the funds across lending markets and strategies, for example Euler, Aave and curated vaults shown in the example allocation. The system rebalances as rates change, and reward tokens are claimed, swapped to USDC and redeposited so yield compounds.

Deposits mint ERC-1155 shares in the user's wallet, and these represent a claim on the vault. Partners can reach the same vaults through an SDK, a white-label front end, or a custom strategy built by Yelay's engineers.

For non-DeFi products the model differs. The BTC collateral flow uses repo or escrow structures to borrow stablecoins against Bitcoin and deploy them into strategies, while the RWA vaults hold private credit and real estate income through a securitisation structure with quarterly liquidity.

Yelay does not publish a full fee schedule for end users on its homepage. The advisory process mentions fee mechanics such as performance, management or SaaS fees, so charges likely depend on how a vault is configured by the partner.

Users would see the fee terms in the vault interface, the docs or the partner's own deposit page. Gas costs on the underlying chain apply to deposits and withdrawals.

DefiLlama lists two audits for Yelay V3, and the site links a security audits page. The homepage says capital is routed through audited protocols, but it does not name the auditors here, so read the reports directly. Vaults are smart contracts, and funds are exposed to bugs in both Yelay's code and every underlying protocol it uses.

The RWA vaults add counterparty and legal-structure risk, since returns depend on lending originators or a real estate developer, and liquidity is quarterly. The BTC collateral flow is described as institutional and structured per deal, so terms differ.

The homepage does not name a team or regulatory status. Treat quoted APYs as historical or target figures. Check the rules that apply to you before using RWA products.

Yelay is mainly for businesses, wallets and fintech teams that want to add a yield product without building vault infrastructure. It also suits DeFi users who want a managed USDC vault, and institutions with the capital for the RWA or BTC collateral products. Beginners who want guaranteed returns or a long track record may prefer to wait.
