39 Commits • 11 Features
Mar 1, 2026March 2026: Delivered expanded Hedera data source capabilities for Ledger Live, including ERC20 data source flag, balance retrieval, last block access, and operations listing; completed deduplication for Hedera ERC20 transfers and fixed an off-by-one timestamp issue in last block data. Implemented staking/fees enhancements with estimateFees and parsing transfers that respect staking rewards, plus a refactor of staking reward calculations. Advanced Aleo transaction workflows with improved mode handling, device transaction configuration, and properties; integrated Aleo signer kit, updated derivation paths, and encrypted prove broadcasting. Added support for ERC20 mint/burn operations and improved balance visibility with a “recently” indicator in Aleo balance. Also improved test reliability and maintainability with test tweaks, i18n fix, and changeset tracking.
