Multi-Signature Wallets

Require multiple approvals for transactions. The gold standard for securing business funds and eliminating single points of failure.

What is a Multi-Signature Wallet?

A multi-signature (multi-sig) wallet requires multiple private keys to authorize a transaction, rather than just one. For example, a "2-of-3" multi-sig needs 2 out of 3 designated signers to approve before funds can move. This eliminates single points of failure—if one key is lost or compromised, your funds remain safe.

Why Use Multi-Sig?

Eliminate Single Points of Failure

No single person or device can drain your funds. Even if one key is stolen, attackers can't access your crypto.

Shared Control

Perfect for businesses, DAOs, and partnerships. Multiple stakeholders must agree before funds move.

Key Recovery

Lose one key? No problem. With 2-of-3, you can still access funds and replace the lost key.

Institutional Grade

Required by many institutions and funds. Demonstrates proper security controls for audits and compliance.

Setup Best Practices

  • Distribute keys across different locations and devices

    Don't store all keys in the same place. Use different hardware wallets, locations, or custodians.

  • Document your setup securely

    Record which keys are where, who has access, and recovery procedures. Store this separately from the keys.

  • Test with small amounts first

    Before moving significant funds, test the entire signing flow with a small transaction.

  • Plan for key rotation

    Have a process for adding/removing signers when team members change.
