Vultisig primary sources — 2026-05-01

Project status in this pass

• No canonical standalone whitepaper or litepaper surfaced.
• The clearest current source of truth is Vultisig’s official site plus its public docs and GitHub organization overview.

Primary-source snapshots

1) Official homepage

• URL: https://vultisig.com/
• Key excerpt:
  • The homepage presents Vultisig as a free MPC wallet that makes seed phrases obsolete.
  • It says the product uses DKLS23-based multi-party computation, supports 30+ chains, and offers both Fast Vault and Secure Vault setups.
  • The page also foregrounds open-source and audited positioning plus a growing ecosystem around the wallet.

2) Docs overview

• URL: https://docs.vultisig.com/
• Key excerpt:
  • The docs describe Vultisig as an open-source seedless cryptocurrency vault built on MPC / threshold signatures.
  • The overview distinguishes Fast Vaults from Secure Vaults and positions the project as multi-platform, multi-chain, and multi-factor.
  • It also maps adjacent surfaces including the wallet, extension, web app, and marketplace.

3) Security & technology overview

• URL: https://docs.vultisig.com/security-and-technology/overview.md
• Key excerpt:
  • Vultisig says no full private key is ever constructed; signatures are assembled from distributed vault shares.
  • The docs present DKLS23 as the current default protocol, describe t-of-n threshold security, and frame GG20 as legacy.
  • Emergency recovery is documented as a last-resort path that converts the vault into a single-signature wallet only if Vultisig software becomes unavailable.

4) Security page

• URL: https://docs.vultisig.com/help-and-legal/security
• Key excerpt:
  • The security page emphasizes open-source transparency, professional audits, and responsible disclosure.
  • It links the DKLS23 implementation to a Trail of Bits audit via Silence Laboratories and explains what Vultisig can and cannot do for users.
  • The page also makes clear that Vultisig cannot access funds or recover lost vault shares.

5) GitHub organization overview

• URL: https://github.com/vultisig
• Key excerpt:
  • The GitHub organization overview describes Vultisig as a multi-chain, multi-factor threshold-signature vault built by THORChain founders.
  • It also says the ecosystem now includes a browser extension, web version, marketplace for plugins and AI agents, a TypeScript SDK, a CLI, and an MCP server.
  • That repo surface makes the project look materially broader than a standalone wallet app.

6) SDK implementation guide

• URL: https://docs.vultisig.com/developer-docs/vultisig-sdk/sdk-users-guide.md
• Key excerpt:
  • The SDK guide documents package installation, initialization, vault creation, verification, address derivation, balance checks, signing, swaps, storage layers, and password management.
  • It distinguishes FastVault and SecureVault modes and includes explicit stateless / serverless usage patterns.
  • This confirms a real developer-facing wallet infrastructure surface for integrations and automation.

Working conclusion

Vultisig is best cataloged as programmable self-custody infrastructure with a wallet front end. The strongest signal is the combination of seedless threshold-signature vaults, explicit multi-device security/recovery logic, and a public developer stack spanning SDK, CLI, marketplace, and MCP surfaces.
