How to Set Up a Multi-Signature Wallet
A practical overview of the general process and decisions involved in setting up a multisig wallet.
Jump to section
What to remember
- Deciding the M-of-N threshold is the foundational multisig setup decision.
- Independent signing devices or parties reduce the risk of a single compromise affecting everything.
- Testing with a small transaction before relying on the setup is a practical safeguard.
- Losing too many required keys can still mean permanent loss of access.
Decide on your M-of-N threshold
The first decision is how many total signers (N) and how many required approvals (M) your setup will use — for example, 2-of-3 or 3-of-5 — balancing convenience against security and redundancy.
A 2-of-3 example: any 2 of the 3 keys are sufficient to authorize a transaction.
Choose independent signing devices or parties
Each signer should ideally use an independently secured device or key, and for organizational multisig, distinct individuals, so that compromising one doesn't automatically compromise the others.
General setup steps
- Generate each signer's individual key pair, ideally on separate, secure devices.
- Create the multisig wallet configuration specifying the total signers and required threshold.
- Test the setup with a small transaction before relying on it for significant funds.
- Securely document the recovery process for each signer, without concentrating that documentation in one place.
Losing too many keys is still a real risk
A multisig wallet doesn't eliminate the risk of losing access — losing more keys than your threshold allows for (for example, 2 of 3 in a 2-of-3 setup) can still mean permanent loss of access.
