Multi-sig that survives time zones on Hedera.
Approve Tuesday, sign Wednesday from London, network executes when the threshold is met. Up to 62 days later. Threshold signatures, agent automation, scheduled async signing. Private keys never leave your device.
Participants join to sign. Coordinators create sessions and build transactions.
How this works. We host the user interface; you (or a teammate) host the coordinator via
npx hedera-multisig server. The dApp connects to that coordinator URL — Vercel never sees your transactions. New here? Try the walkthrough →Treasury management
