No identity

Liquidity vaults

Build liquidity vaults that survive Q-day.

A vault is bound to its owner's post-quantum identity. Funds leave only when the contract checks a one-time signature itself, then the remainder rolls into vault[i+1], which the next unused leaf signs for.

The contract checks the key itself.

Funds leave a vault only when the contract verifies a hash-based signature from the identity it is bound to. No secp256k1 signature can move them alone, and no leaf is ever used twice.
