Detailed Explanation
How It Works: A multisig contract holds the funds. Signers each control their own keys, often on separate hardware wallets. To execute a transaction, the required threshold of signers must each approve. The contract verifies the signatures and broadcasts.
FAQs:
Is a multisig fully on-chain? On EVM and similar chains, yes — the contract enforces it. On Bitcoin, it is enforced by Bitcoin script.
What if a signer loses their key? As long as the threshold can still be reached, you can rotate the lost signer out via a transaction.
