Sierra Protocol Review 2026: RWA and DeFi Yield Vaults

Sierra Protocol is a vault protocol that offers access to real-world asset and DeFi yield onchain. Its homepage describes it as the permissionless RWA vault protocol, with institutional-grade vaults, no minimums and global access. DefiLlama files it under Yield and describes it as issuing SIERRA, a Liquid Yield Token built to serve users across CeFi and DeFi.

The project serves three groups. Individual and treasury depositors can put idle balances into curated vaults. Fintechs and platforms can power a whitelabeled earn product. Asset managers and RWA issuers can launch vaults to distribute onchain.

DefiLlama shows about $37.3 million in TVL across Ethereum, Avalanche and Plume Mainnet, down 14.5% over seven days, and lists it since February 2026. That is a young protocol with meaningful deposits, and the data supports treating it as early-stage.

Sierra Protocol packages yield strategies into vaults. Each vault is backed by real-world assets such as money market funds or private credit, DeFi strategies such as stablecoin staking and lending, or a mix of both. You deposit into a vault and receive a vault token whose value tracks your balance and accrued interest.

Every vault starts as a simple deposit, earn and withdraw product. If you need more flexibility, you can use a Liquid Vault Token that can be traded, used as collateral and built on by other platforms. The site says secondary market liquidity comes through Authorized Participants, bridging uses LayerZero OFT, and an onchain NAV oracle from RedStone supplies pricing.

For businesses, Sierra works with infrastructure partners that handle smart contracts, legal structure, custody and reporting for custom vaults, while Sierra provides onchain access. That means returns depend on both onchain contracts and off-chain asset managers.

Fees are not published in the material reviewed. The homepage does not state management, performance, deposit or withdrawal fees for its vaults.

Users would expect to find fee terms on each vault's page in the app or in the Sierra documentation. Underlying funds and partners may charge their own fees, which would reduce net yield, and network gas fees apply on each chain.

DefiLlama lists two audits for Sierra Protocol and the website links to a contract audits page. The material reviewed does not name the auditors or summarize findings, so readers should read the reports directly. No hacks or incidents are mentioned publicly reviewed, but the protocol has been listed only since February 2026.

The main risks go beyond smart contracts. Yield from RWAs depends on off-chain managers, custodians and legal structures run by partners. Vaults can include pausing and freezing controls, and secondary liquidity depends on Authorized Participants. Regulatory treatment of tokenized RWA products varies by jurisdiction, so check what applies where you live. Only deposit what you can afford to lose.

Sierra Protocol is for yield seekers comfortable with onchain products who want RWA exposure, and for fintechs, treasuries and asset managers that want to offer or launch vaults. It is less suited to users who want fully trustless, permanently open access with no compliance controls, or those who need fee details before they deposit.
