Apr 1, 2026

April 2026 monthly summary focused on expanding external API integration capabilities through a JWT-authenticated HTTP client for the CHOMP API. Delivered a new chomp-api-service package in MetaMask/core, enabling client apps to perform authenticated write operations to the CHOMP API via a JWT bearer token sourced from the messenger, with a BaseDataService pattern and messenger-callable methods for address association, account upgrades, delegation verification, intents, withdrawals, and service-details lookup. Implemented runtime validation with superstruct, explicit status handling, and comprehensive tests using nock. Updated repo wiring, docs, and changelogs to reflect the new capability. No critical bugs closed this month; primary value delivered through a robust, scalable integration layer and improved external API tooling.

March 2026 (2026-03) delivered a dedicated Ethereum Money Keyring feature for MetaMask/accounts, enabling money account management on top of the existing HD keyring. Implemented via a new @metamask/eth-money-keyring package with a fixed derivation path (m/44'/4392018'/0'/0) and a dedicated Money Keyring type, along with single-account enforcement. This work is integrated into the repository tooling and API surface (updates to @metamask/keyring-api, tests, and changelog). Commit: a806bb5e4d61badc506d9f51ea332e6724c4c989.

January 2026: Focused improvements in the metamask-docs repo to enhance user guidance and routing reliability. Implemented POH Failure Alert Documentation Link Update to point users to the new documentation page, and fixed a faucet URL by removing a trailing slash to ensure correct routing. These changes reduce support friction and prevent broken links, contributing to a smoother onboarding and support experience for users.
