Ledger: Integration of EIP1559 for Ethereum mainnet

About Ledger

Ledger has a range of the most popular hardware wallets in the industry. These store a user’s private key enabling them to hold cryptocurrency and sign transactions more securely. Ledger provides two different models, the Nano S Plus and Nano X, the latter connecting through Bluetooth, both of which support over 5,500 digital assets . The hardware wallets come equipped with the Ledger Live app, that allows users to buy, sell, own, and invest their crypto assets. Ledger has over 2M users in 165 countries.

The Challenge

Ethereum EIP1559 is a change to the Ethereum protocols that allows the user to pay a high gas fee in order for their transaction to be prioritised (or a lower one, for lower priority and longer processing time). Ledger commissioned Applied Blockchain to add support for Ethereum’s EIP1559 in the Ledger live app. With this integration, both the Ledger Live Desktop and Ledger Live Mobile apps allow users to utilise EIP1559 transactions on Ethereum.

What Applied Blockchain Delivered

Applied Blockchain designed and developed this integration in collaboration with the Ledger Live app product team. The changes were implemented in the transaction generation and signing logic.


EIP1559 replaces the first-price auction as the main gas fee calculation and embeds an average price for Ethereum transactions. As Ethereum is one of the most popular cryptocurrencies in the Ledger Live app, this feature was highly anticipated by the platform’s users.

Victor Baconnet, Product Owner, Ledger

“The Applied Blockchain team has been super kind and super helpful. I’d say it’s been super easy because also all the project management side of this was taken care of, the roadmap was very clear, the vision was very clear and it ensured basically that everything went really smoothly and it freed a lot of time actually on our side to just focus on quality and focus on the product side of things when you have a great team working on your future.”
