Benjamin Haramboure developed end-to-end Speculos swap tests for SOL/USDC with ETH_USDC support in the LedgerHQ/ledger-live repository, focusing on expanding automated test coverage for cross-asset swaps. Using TypeScript and leveraging E2E testing frameworks, he introduced new account and currency enums to support ETH_USDC workflows and scaffolded multi-scenario test cases to enable future asset integrations. His work identified a flaky balance retrieval issue, which he documented for future resolution, and laid a foundation for more reliable releases. The depth of his contributions improved release reliability and positioned the team to accelerate support for additional assets in Ledger Live.
