Setting Up a Multisig Wallet

A multisig (multi-signature) wallet requires more than one private key to authorize a transaction. If you’re managing a project treasury or community funds, a multisig setup protects against a single point of failure — whether that’s a hack, a lost key, or a bad actor on the team.

​
Why use multisig?

  • Security — no single person can move funds unilaterally
  • Trust — your community can see that treasury funds require multiple signers
  • Resilience — losing one key doesn’t mean losing the funds

​
Multisig on Cardano

Cardano supports native multisig through its script address system. A common setup is M-of-N — for example, 2-of-3 means any 2 out of 3 keyholders must sign a transaction. Roundtable is a Cardano multisig tool built specifically for DAOs and project teams.
1

Go to Roundtable

Visit roundtable.adaodao.org and connect your wallet.
2

Create a new multisig wallet

Click Create wallet and add the public keys (or wallet addresses) of each signer.
3

Set the threshold

Choose how many signers are required to approve a transaction (e.g. 2 out of 3).
4

Save the wallet address

Once created, your multisig wallet has its own Cardano address. Share it with your team.

Option 2 — Eternl native multisig

Eternl wallet has built-in multisig support. Go to Settings → Shared wallet to set it up with other Eternl users.

Best practices

  • Use at least a 2-of-3 setup for any meaningful treasury
  • Store each key on a different device and ideally held by different people
  • Document who holds which key and store that information securely
  • Test with a small transaction before moving significant funds
If you lose enough keys to fall below the signing threshold, the funds in the multisig wallet are permanently inaccessible. Back up every key carefully.
