July 2025 monthly summary for LedgerHQ/app-exchange: Focused on stabilizing the CI testing environment for Hedera and App-Exchange to improve reliability of integration tests and ensure test environments reflect production defaults. Key actions included aligning Hedera and App-Exchange test repositories and branches to production defaults, reworking CI references to production repos, and implementing temporary adjustments for Hedera integration from blockydevs. GitHub Actions testing was configured to run against production-ready app-exchange settings, enabling deterministic feedback and faster triage. Implemented with commits 087b148218d3beb843278abd73e43f29866e2f78, 402d3759e83f73d5b1a2226cc97a4f0637397879, and 08de087ec1ea6f3cac684dbd1c26f2f74441a789. Overall impact: more reliable CI, fewer flaky tests, and a clearer production-baseline for future releases. Technologies/skills demonstrated: CI/CD, test automation, GitHub Actions, release engineering, environment configuration, Hedera integration testing, repo orchestration.

June 2025 monthly summary for LedgerHQ/app-exchange focusing on delivering business value through reliable test infrastructure, expanded cross-chain test coverage, and sustainability of release processes. The team concentrated on strengthening CI/CD, aligning test configurations across TON and Hedera, and stabilizing test baselines, while extending support for SPL Token 2022 in tests and refining TON USDT transaction handling. Documentation and visual baselines were refreshed to reduce misconfigurations and improve consistency across devices. No customer-facing bugs were reported this month; the emphasis was on preventing regressions and accelerating release cycles through robust test infrastructure and clear release housekeeping.

May 2025 highlights: Expanded the Ledger app data model to support qubic data by adding a new qubic entry in the ledger database, enabling richer analytics and data-driven features. Stabilized Hedera testing and QA by consolidating test environment configuration and CI pipelines across app-exchange, conftest, test cases, and swap pipelines—adding Hedera to allowed apps and supported currencies, updating snapshots and test inputs, and regenerating golden runs. Implemented Hedera transaction signing and signature verification in HederaClient, enabling end-to-end signing and verification workflows with public key retrieval and nacl-based verification, backed by dedicated tests. Together, these workstreams improve product reliability, expand supported use-cases, and reduce release risk. Technologies used include database schema extensions, test automation, CI/CD, test fixtures, snapshot testing, and cryptographic verification using nacl.

April 2025: LedgerHQ/app-exchange focused on stabilizing Hedera-related tests. By updating snapshot references and adjusting the valid-send-amount constant to align with updated Hedera parameters, we reduced flaky test failures and improved CI reliability ahead of release. No new user-facing features were shipped; the month’s work was aimed at test reliability and maintainability of the Hedera integration.
