A cold multisig wallet is a wallet that holds private keys offline and enhances security by requiring approval from multiple authorised signers before executing a transaction, thus minimising the risk of unauthorised access. In Liminal Vaults, you can send and receive funds from other wallets.

Important Note:

• For EVM Chains, the other signers will be able to cross-verify the message hash and domain hash they see on the hardware device on the Gnosis Safe UI or third party tools. See How to Verify Message Hash and Domain Hash to avoid blindly signing messages on your hardware device.

As soon as the transaction is initiated, all the other signers will receive a notification about the transaction via email. To sign the transaction, they can log into their Liminal Vaults and view the pending transaction under Pending Actions. In case of EVM Chain transactions, they can verify the message hash and domain hash using a Safe utils app by manually inputting the input details and additionally, cross verify it on the Gnosis Safe UI. Once verified, they can select the approve button in the dashboard, connect their hardware device, and follow the approval instructions on their hardware devices to sign the transaction.

Once the minimum number of signatures are collected, the transaction is broadcasted to the blockchain.
