Multi-Sig: Threshold-Authorized AUUM Spending

A planned native complement to MPC custody -- instead of one BLS-verified group signature (MPC's approach on the EVM side), Multi-Sig will let multiple distinct AUUM keys jointly authorize a spend directly at the native chain layer, each key visible and accountable on its own.

Not yet built -- no committed date

Honest status

Unlike every other page in this set, this one describes something not yet built. MPC custody already solves distributed signing for EVM-side wallets via BLS threshold signatures; Multi-Sig is the planned equivalent for native AUUM itself -- multiple distinct keys, each independently identifiable, jointly required to authorize a spend, without the BLS aggregation step. Listed here as a real roadmap item because it's a real gap worth naming, not dressed up as a launch.

The vision

  • M-of-N native AUUM spending -- each signer visible and accountable on their own, no threshold-signature aggregation.
  • Treasury and DAO spending that needs a visible paper trail of who signed, not just that a threshold was met.
  • A complement to MPC custody, not a replacement -- different tradeoffs for different needs, both available on the same platform.
