Every normal wallet is signed with ECDSA — a signature a quantum computer will one day break. Once you've sent a transaction, your public key is on-chain forever. Paste an address and see how exposed it already is.
Any EVM address or ENS name. Read-only — we never ask for keys or a signature.
Whether your ECDSA public key is already on-chain, the value behind it, and how long it's been harvestable — scored 0–100.
Claak controls funds with a post-quantum key (SPHINCS+ / Falcon), checked on-chain — immune to Shor's algorithm.
