Nov 1, 2024November 2024 highlights for 0xPolygon/heimdall-v2: cross‑chain bridge readiness, testnet reliability, and deployment automation. Delivered Bor Chain gRPC integration and REST bridge readiness, including config flags and startup sequencing to ensure the bridge starts only after the REST server is up. Introduced Bridge Process Control CLI flags (--all, --only) to improve orchestration and deployment flexibility. Fixed stability and determinism issues in testnet/devnet workflows, covering signer data handling, key initialization, genesis state setup, and signer data capture for reproducibility. Upgraded dependencies and performed targeted code cleanup (Cosmos SDK version bump, removal of redundant components) to reduce technical debt and boost maintainability. Overall, the changes deliver measurable business value through more reliable bridge operation, faster developer onboarding, and repeatable test environments.
