What is Sommelier (SOMM)?

🟢 The simple version
Plain English — no jargon. Start here.
Sommelier is a Cosmos-based protocol that runs automated DeFi "cellar" vaults — ERC-4626 smart vaults managed by off-chain strategists who can actively rebalance positions across Uniswap, Aave, and other DeFi protocols in response to market conditions, without users needing to do anything.
What are "cellars" and why the wine metaphor?
Sommelier's vault products are called "cellars" — playing on the wine sommelier theme. A cellar is an ERC-4626 compliant vault (the DeFi standard for yield-bearing tokens) that accepts deposits and deploys them into DeFi strategies. The key difference from static vaults: Sommelier cellars are actively managed. Off-chain "strategists" — algorithms or humans — send rebalancing instructions to the vault via Sommelier's Cosmos-based validator network. The validators act as a trust layer: strategists can only execute pre-approved actions, so they can't steal funds, but they can change position allocations within defined parameters.
Think of it like a robo-advisor for DeFi. Rather than depositing into a static Uniswap v3 position and watching it go out of range as prices move, a Sommelier cellar's strategist can continuously adjust the range to stay efficient. Rather than a fixed allocation to Aave, the cellar can shift between Aave, Compound, and Morpho based on which offers the best rates.
Why Cosmos for an Ethereum vault?
The cellars themselves are Ethereum smart contracts. But the strategist instruction layer runs on a Cosmos-based blockchain — Sommelier's own chain. This separation means: the EVM vaults hold funds and execute trades, while the Cosmos chain handles the governance and instruction routing. Validators on the Sommelier chain must approve strategist instructions before they're sent to Ethereum, creating a decentralised check on what strategies can do.
Is SOMM legal in India?
Yes. SOMM qualifies as a Virtual Digital Asset (VDA) under Indian law. 30% tax on gains and 1% TDS applies. Always consult a tax professional.

Sommelier's cellar strategies
Sommelier has launched multiple cellars targeting different DeFi strategies: Real Yield ETH (deploying across Aave, Compound, Morpho for the best lending rates), Turbo strategies (using leverage loops to amplify yields), and concentrated liquidity management on Uniswap v3 (rebalancing LP ranges automatically). Each cellar has a different strategist, risk profile, and underlying protocol exposure. Users choose which cellar matches their risk tolerance — some are more conservative (stablecoin lending), others more aggressive (leveraged ETH strategies).
The ERC-4626 standard means cellar positions are tokenized — you receive a cellar token representing your share. These tokens are composable: other DeFi protocols can accept Sommelier cellar tokens as collateral, similar to how Aave accepts staked ETH tokens. This composability is the long-term vision — Sommelier vaults as a DeFi building block.
Sommelier's active management is also its risk. A bad strategist decision, a smart contract bug in the vault, or a failure in the Cosmos validator layer could all cause losses. Unlike a static Uniswap position where you can verify exactly where your funds are at any moment, active vaults change allocations continuously.

SOMM token and governance
SOMM is the native Cosmos chain token — used for staking by validators (who secure the instruction layer), paying fees, and governance. SOMM holders vote on which strategists can manage which cellars, what types of strategies are permitted, and protocol upgrades. This makes SOMM more of a validator/governance token than a direct yield-bearing token — the yield goes to cellar depositors, while SOMM captures value from the protocol's role as the trust and coordination layer.
