# Setting Up a Multisig Wallet

> How to secure your project treasury with a multisig wallet on Cardano

# 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.

## Option 1 — Roundtable (recommended)

[Roundtable](https://roundtable.adaodao.org) is a Cardano multisig tool built specifically for DAOs and project teams.

<Steps>
  <Step title="Go to Roundtable">
    Visit [roundtable.adaodao.org](https://roundtable.adaodao.org) and connect your wallet.
  </Step>

  <Step title="Create a new multisig wallet">
    Click **Create wallet** and add the public keys (or wallet addresses) of each signer.
  </Step>

  <Step title="Set the threshold">
    Choose how many signers are required to approve a transaction (e.g. 2 out of 3).
  </Step>

  <Step title="Save the wallet address">
    Once created, your multisig wallet has its own Cardano address. Share it with your team.
  </Step>
</Steps>

## 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

<Warning>
  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.
