Ledger Multisig is an application that provides access to Safe Accounts, enhancing security by requiring multiple approvals to complete a transaction and other types of interactions.

With a regular Ledger single signer setup, one device (one “key”) is enough to approve all transactions. In contrast, Ledger Multisig (short for multiple-signatures) requires a predefined number of approvals from different Ledger devices (different “keys”) before a transaction can be executed.

Ledger Multisig is built on the Safe protocol, a smart contract that runs on the blockchain. This setup is particularly useful for managing shared funds or securing high-value transactions, as it removes the risk of a single point of failure.

Ledger Multisig is designed for situations where you want additional security, governance and shared control over funds.

• For Teams or DAOs (Decentralized Autonomous Organizations): Multiple team members can be required to approve transactions, preventing a single operator from accessing or spending all the funds. This also creates a transparent record of approvals. 

• Managing smart contracts: Ledger Multisig adds a layer of protection for important smart contracts, by requiring approvals before any upgrades or critical changes can be made.

Ledger Stax™ and Ledger Flex™ provide the full Ledger Multisig experience, including transaction signing with our unique Clear Signing feature.

Ledger Nano X™ or Ledger Nano S Plus™ can be used to connect, view balances and see pending requests. However, these devices cannot be used to sign transactions.

Ledger Multisig currently supports popular EVM (Ethereum Virtual Machine)–compatible networks, including:

• Ethereum Mainnet

• Base

• Optimism

• Arbitrum

• Polygon

We plan to expand support to additional networks based on user needs.

In Ledger Multisig, each operator role has a specific responsibility:

• Approvers: Approvers hold a Ledger device with a private key. Their signature is required to authorize and execute transactions. Approvers can also propose transactions.

• Proposers: Proposers can initiate and submit transactions for review but cannot approve them. This role is useful in larger teams where some members prepare transactions and others are responsible for approving them.

The confirmation threshold is an important security and governance setting in Ledger Multisig. It defines the minimum number of Approver signatures required for a transaction or major change to be executed.

For example, if you have a "2-of-3" Multisig, it means 2 out of your 3 designated Approvers must sign before the transaction can proceed.

You can adjust the confirmation threshold, but always ensure that enough active Approvers are available to meet the requirement you set.

Clear Signing is a security feature that ensures you are approving exactly the transaction you intend to make. When you sign a transaction with your Ledger device, the important details (such as the recipient address, asset type, and amount) are displayed directly on the Ledger Secure Screen.

Since the information is shown on your Ledger device (and not only on your computer), you can be certain that “What You See, Is What You Sign” (WYSIWYS). This protects you from risks such as malware that could attempt to alter transaction details on your computer.

Blockchain transactions are generally irreversible. If funds or assets are sent to the wrong address, they cannot be recovered.

For this reason, it is essential to carefully verify the recipient wallet address on your Ledger device using Clear Signing before approving any transaction.

Gas fees are the network costs required to process and validate transactions on the blockchain network. Each time you send assets or make a change to your Ledger Multisig, you need to pay a fee to the network to process your transaction. The amount varies depending on network activity and congestion.

For Ledger Multisig transactions, gas fees are paid during your transaction. These fees are only charged when a transaction is executed and broadcast to the blockchain, not when it is simply Proposed or Signed. Gas fees are payable to the blockchain network even if a transaction fails to complete due to a network error and are non-refundable.

Yes. In addition to the blockchain network gas fees which are independent of Ledger, Ledger charges a service fee (“Multisig Fee”) for using the Ledger Multisig application, which is paid via the priority fee:

• Flat Fee: $10.00 USD for all transactions except token transfers.

• Variable Fee: 0.05% of the transferred amount for token transfers.

Please note that the Multisig service may facilitate access to Third-Party Services (as defined in the Ledger Multisig Terms of Use).  Any fees for these services are determined and charged by the Third-Party Services providers themselves. In addition to these fees, Ledger charges a fee for the secured and facilitated access it provides to these services through Ledger Multisig (“Transaction Fee”). The Transaction Fee may be charged directly to you or indirectly if it is included in the Third-Party Services provider's fees and paid to Ledger on your behalf.
