Multi-Sig: Multi-Chain Threshold Custody
Multi-signature custody as a package you run yourself or a service we manage for you -- M-of-N signer authorization across five chains: AUUM, Ethereum, Sui, Stellar, and Hyperliquid. Every signer stays independently identifiable and accountable, using the multisig primitive native to each chain.

A second custody model, same platform
Multi-Sig sits alongside MPC custody rather than replacing it: instead of one BLS-verified group signature, multiple distinct keys jointly authorize a spend, each one visible and accountable on its own. Take it as a self-hosted package to run inside your own infrastructure, or as a fully managed service we operate for you -- natively on AUUM, and through each chain's own multisig primitive on Ethereum, Sui, Stellar, and Hyperliquid.
Five chains, one custody model
- AUUM -- multiple distinct AUUM keys jointly authorize a spend directly at the native chain layer, no threshold-signature aggregation.
- Ethereum -- contract-based M-of-N wallets, each signer an independently identifiable on-chain address.
- Sui -- native weighted multisig addresses: multiple public keys and a threshold, no separate contract required.
- Stellar -- native account signers with per-signer weights and configurable thresholds.
- Hyperliquid -- multi-signer authorization for account and vault-level actions.
