What can you do with a multi-sig inbox?
When outbound email requires collective approval, entirely new coordination patterns become possible.
Governance & Resolutions
Board decisions require 3-of-5 signers before the email sends. The message is the vote — no separate tooling needed.
Escrow & Conditional Release
Hold sensitive documents in an inbox that only unlocks when N parties agree. Mediation where neither side can act alone.
Whistleblower Coordination
Evidence requires M-of-N co-signers before release. Dead man’s switch if a signer goes silent. Nobody goes first alone.
Social Key Recovery
Lost access? 3-of-5 trusted contacts co-sign your restoration. No phone number, no backup email — a trust network.
Tamper-Proof Audit Trails
Every email read and sent is co-signed. Cryptographic proof of who approved what, when. Built for compliance.
Treasury & Payments
Invoice arrives, 2-of-3 finance team co-sign the reply authorizing payment. Bridges email to on-chain wallets.
