February 2025 - Version 5.5.0

Tradelink Automatic Repledge

Tradelink users now have access to our new Automatic Repledge feature. This allows Asset Managers and Exchanges to configure Settlements in a way that means any profits moving from the Exchange to the Asset Manager are automatically added to the existing pledge between these two parties. This helps to increase trading efficiency, allowing both Asset Managers and Exchanges to focus on trading, not the manual operations surrounding trading.

January 2025 - Version 5.4.0

BASE support

We are excited to announce the addition of support for BASE Mainnet to the Ledger Vault. This new feature will allow clients to store and manage their BASE assets securely on the Ledger Enterprise Vault. BASE is a layer-2 scaling solution for Ethereum that offers faster transaction speeds and lower fees. With the addition of BASE support, the Ledger Vault continues in its endeavour to offer clients the widest range of assets possible.

December 2024 - Version 5.4.0

EIP-1559

We're excited to announce support for EIP-1559 transactions on the Ethereum network. This enhancement allows for more predictable transaction fees through an improved gas fee mechanism. With EIP-1559 support, your transactions can now include both a base fee and priority fee, helping to reduce overpayment and providing better fee estimation. This update streamlines the transaction process by automatically adjusting gas fees based on network demand, potentially leading to cost savings and faster confirmation times. You can now take advantage of this feature directly through your Vault workspace when sending Ethereum transactions.

Tradelink Settlement and Withdrawal flows

Settlement UI is creating a distinct Settlement approval flow for Asset Manager and Custodians when an exchange initiates a settlement. Traditionally, this looked like a regular transaction flow which could be quite confusing for these users when they were expecting a settlement.

Withdrawal is simply changing the nomenclature of transaction flows in collateral accounts so that it more closely aligns with nomenclature in trading institutions (from Send and Receive to Withdraw and Deposit).

November 2024 - Version 5.2.0

Replace by Fee

Ledger Enterprise users (operators) now have access to Replace by Fee (RBF) on the Bitcoin Network. RBF is a feature that lets you manage your Bitcoin transactions more efficiently. With RBF, you can replace an unconfirmed transaction in the Bitcoin mempool with a new transaction that includes a higher fee. This incentivizes miners to prioritize and confirm your transaction faster, especially during times of network congestion.

How to Use RBF To use RBF in the Vault, you have two options: "Boost" or "Cancel."

• Boost : Ideal when you have a pending transaction in the mempool and want to speed up its confirmation. By increasing the fee, you improve the chances of your transaction being processed quickly.
• Cancel : Use this option to attempt to cancel a transaction that hasn't been confirmed yet. You might need to do this to correct an error in the transaction details or if you decide not to proceed with the transaction. Please note that the Cancel feature is not guaranteed to work, as miners may still prioritize the old transaction over the new one.

For information on how these features work operationally, please refer to this page.

Automatic Logout and Session Refresh

We've enhanced the security and user experience of the Ledger Vault. Now, if a session expires due to inactivity, you'll be automatically logged out after 10 minutes. This helps protect the privacy of your Vault's content, prevents unexpected errors and ensures a smoother workflow. Additionally, a banner will appear one minute before your session expires, giving you the option to extend your session for another 10 minutes with a simple click. This will help avoiding an unexpected logout while working on a transaction for example.

Interface Updates

The Ledger Vault interface is being updated with new animations and icons to provide a more intuitive user experience. These updates also prepare the Vault for upcoming features, including Ledger Stax compatibility.

October 2024 - Version 5.1.0

April 2024 - Version 4.34.0

Overview

We are excited to announce the latest Ledger Enterprise release (ver. 4.34), which brings following enhancements:

• Enhanced Compliance capabilities : sign Proof of Ownership messages on any network.
• Mark objects as spam : marking accounts and operations as spam and filter on them.

Enhanced Compliance capabilities: sign Proof of Ownership messages on any network

As a Ledger Enterprise user, you will now be able to define and use Message Signing capabilities across all supported networks. This enables you to sign Proof of Ownership messages, should you require it for Compliance purposes. Indeed, signing messages with a private key can be used to prove that an institution controls the private keys that correspond to its public addresses.

You can find out more about this feature in the dedicated spaces:

• for Admins : activate Message Signing on an account.
• for Operators : sign an EIP-191 compliance Message.

Mark objects as spam

As a Ledger Enterprise use (admin or oprator), you will now be able to mark/unmark an account or transaction as spam and then filter on this new tag. This is to reduce the risk that your operators accidentally use, in new operations, addresses from poisoning transactions. Note still that operators should always use the "receive" button to generate receive addresses safely, and not copy addresses from the operations history. Finally we strongly suggest to use whitelists systematically.

Please find more information on address poisonong scams here.

Process for marking accounts as spam:

Clicking on the button with the three dots "..." will display the context menu for you to mark or unmark an account as spam. You can find documentation for adding a label to the Account matching the ID here.

Please note that only "view-only" accounts can be marked as spam, meaning only LAM and API operators and all admins can mark accounts as spam.

Process for marking operations as spam:

Clicking on the button with the three dots "..." will display the context menu for you to mark or unmark an operation as spam. You can find documentation for adding a label to the transactions matching the ID here.
