Set up a cold multisig wallet

A multisignature (multisig) wallet is a hardware wallet where your private keys are held offline. You connect your hardware device to your laptop to approve a transaction.

Before creating a cold multisig wallet, ensure that your hardware device is set up and linked with your account in your organisation in Vaults. If not, refer to the Set up your multisig wallet guide.

In Vaults, you can create and manage your cold multisig wallets. You can add the minimum quorum of transaction signers for the wallet transactions.

Note
If you are creating any of the following Multisig wallets, then:

Tron Mulltisig wallets:

Sprayer wallets are used to fund Tron Multisig wallets during their creation. Ensure your Tron Sprayer wallet has sufficient balance. Learn how to refill your Sprayer wallets here.

Ensure you have at least 120 TRX in your Tron Sprayer wallet.

EVM-based Multisig wallets:

Gas Station wallets are used to fund the EVM-based wallet creation. Ensure your Gas Station wallet is sufficient balance.
