QUVR Risk Oracle

Uniswap v4 hook

A Uniswap v4 pool with this hook asks the oracle about the token being bought. If the token has a fresh “High risk” label, the buy goes through only with an “I understand the risk” acknowledgement — the wallet or site shows a warning and passes it. Selling is never restricted. No label or older than 3 days — the pool works normally. The hook has no owner.

For developers

interface IQuvrRiskOracle {
    function isHighRisk(address token, uint256 maxAge)
        external view returns (bool known, bool high);
}

(bool known, bool high) = oracle.isHighRisk(token, 1 days);
if (known && high) {
    // show a warning / require confirmation
}
