Trusted by
Web3 Foundation
Treasury coordination and multisig operations for the primary funding body of the Polkadot ecosystem.
Mythos Foundation
On-chain treasury management for one of Polkadot's largest ecosystem partners and gaming deployments.
Parachain teams & bounty curators
Default multisig infrastructure for DAOs, bounty committees, and teams running shared on-chain treasuries.
Stack
Substrate multisig
N-of-M threshold signing on the Polkadot runtime. Deterministic addresses, permissionless creation.
Proxy accounts
Rotate signatories without changing the multisig address — using Substrate's proxy pallet underneath.
Batch extrinsics
Multiple calls in a single on-chain transaction. Bulk payouts, multi-target transfers, batch governance actions.
OpenGov from multisig
Vote on referenda directly from a multisig account — teams participate in governance without routing through individual wallets.
Hardware signing
Polkadot Vault support — air-gapped signing for high-value treasury operations.
SDK

The PolkaSafe SDK exposed the full Substrate multisig and proxy pallet surface as a composable API — letting external teams integrate multisig coordination directly into their own products without rebuilding the primitives. Sub.id was the first integration.

Accounting: QuickBooks · Xero · Zoho Books export pipeline for on-chain transaction records.

Reference

Listed in the official Polkadot Wiki as a recommended multisig solution for the ecosystem.
