Built to survive
twenty winters.
Overwinter is a non-custodial vault that earns swap fees in deep, battle-tested stablecoin pools on Ethereum. It doesn't try to win the yield race. It tries to be the last vault standing.
Principles enforced in code, not in trust.
Survival is the strategy
Principal protection outranks yield, every day. A modest path with no chance of ruin beats a faster one that can end at zero.
No one takes custody
Each depositor interacts with an immutable vault from their own wallet and can redeem at any time, without anyone's permission.
Intelligence advises, code decides
An agent swarm monitors pegs and pools and recommends. It holds no keys that move funds. Rules are enforced on-chain.
Twenty years is the unit of time
Most days, the right action is to do nothing. Short-term differences of a few basis points are noise.
Observe, recommend, decide.
Continuous monitoring
Sensors read Chainlink prices every minute and Curve pool balances every five, on Ethereum mainnet.
Typed, validated intents
Analysts turn signals into proposals that are recomputed deterministically and checked against policy before anyone sees them.
Humans and timelocks
Risk-increasing changes pass a multisig and a timelock. Exits are never gated, and the vault's caps are enforced in code.
No vault until the evidence says so.
No vault is deployed and there is nothing to deposit. Each phase must meet its acceptance criteria before the next begins.
