Video Case Study

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.

The Deliverables

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.

The Outcome

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.
