Sommelier

Sommelier is a decentralized finance protocol that provides automated portfolio management and vault optimization for DeFi assets. The platform enables liquidity providers to execute complex, automated financial transactions such as portfolio rebalancing, limit orders, and batched orders through smart contracts that operate with full on-chain transparency. Sommelier functions as a protocol logic layer rather than a vault UI, integrating across chains and frontends while passing rebalance instructions without bridging assets. The platform offers market-adaptive vaults including Real Yield ETH, Real Yield BTC, and Real Yield USD strategies that maximize yields through leveraged staking and liquidity provision across protocols like Aave, Compound, and Uniswap V3. Vault execution logic follows deterministic rules or AI agent models rather than hidden strategist decisions, with all actions verifiable on-chain. Security is maintained through independently audited smart contracts, validator oversight instead of multi-sig controls, and governance-approved vault onboarding. Founded in 2020 and headquartered in San Francisco, Sommelier has raised $26.5 million in Series A funding from investors including Multicoin Capital, Standard Crypto, Alameda Research, and Polychain.
