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.
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.
