Trails API adds gas fee option selection to the intent flow, persists wallet configuration at quote time, and fixes a recovery issue for intents using custom address overrides.

New

  • Intents now support gas fee option selection. Specify fee options at quote time; the API validates the selected option against quoted options before execution, giving integrators explicit control over transaction costs.
  • Wallet configuration is now stored at quote time and returned with the quote response, enabling reliable intent recovery and re-execution across sessions.

Fixed

  • Recovery now correctly applies custom address overrides when deriving wallet context, preventing derived-address mismatches for intents configured with non-default addresses.

Trails SDK and widget ship smarter intent protocol defaults, better recipient handling, and improved error recovery.

New

  • The SDK now automatically resolves the best intent protocol version for each transaction. An explicit override, global config, or SDK default is checked in order, with a fallback to the API-provided default when the preferred version isn’t supported.

Updated

  • The widget highlights the recipient address when it differs from the sender, making it easier to spot send-to-other flows before confirming.
  • Expired quote errors now show a warning icon and offer a clear recovery path so users can retry without restarting the flow.

Fixed

  • Fixed an issue where the recipient address could go stale after switching wallets in the widget.
  • Fixed the add-wallet flow in the recipient selector so users can successfully add new recipient addresses.

Bor v2.7.1 stable ships opt-in EVM execution optimizations, database performance improvements, and a goroutine leak fix.

New

  • Added opt-in EVM execution optimization via --switch-dispatch CLI flag or EnableSwitchDispatch config option, introducing a fixed-size opcode stack and a switch-dispatch fast path for hot opcodes ported from GEVM

Updated

  • Tuned PebbleDB write path (1 MiB BytesPerSync, adaptive compaction) and increased PathDB state buffer to 2 GB with intelligent carry-over across flushes, reducing write stalls for archive and full nodes
  • Removed legacy UpdateDeps/GetDep DAG algorithm from BlockSTM, fully replaced by the DepsBuilder implementation

Fixed

  • Fixed goroutine leaks in the witness request path that caused unbounded memory growth when peers disconnected during parallel stateless import

aggkit fixes claim syncer startup block selection on empty databases.

Fixed

  • Claim syncer now determines its starting block from the earliest settled reference block (not the latest) when the database is empty on startup, preventing sync errors on fresh starts

Bor v2.7.1-beta ships transaction propagation improvements and an SRC buffer reduction, with additional RPC and monitoring fixes merged to the development branch.

Updated

  • Increased max transaction packet size from 100 KB to 1 MB, improving transaction propagation between peers
  • Reduced SRC buffer from 500ms to 100ms, allowing block producers to spend more time on transaction execution

Fixed

  • bor_getLogs and bor_getLatestLogs now correctly return state-sync logs from blocks produced before the Madhugiri upgrade
  • Prometheus _count metrics no longer reset to zero on each scrape, restoring correct rate(), increase(), and latency calculations for node operators

The Polygon Wallet adds private token transfers via Hinkal and Yield vault support in the Earn tab.

New

  • Added end-to-end private send flow via Hinkal, including a dedicated status screen for deposit, withdraw, success, and failure states, and refreshed gas and privacy fee display with up to 4 decimal place precision
  • Added Yield vault support to the Earn tab

AggLayer raises the default settlement confirmation count to 12 for safer out-of-the-box deployments.
  • Default confirmations for L1 settlement increased from 1 to 12. Deployments that do not set this value explicitly are now safer by default.

Trails
Trails API adds a new option to suppress passthrough quotes from intent responses.
  • Added intents.disable_passthrough_quotes option. When set, the API omits passthrough quotes from intent results, giving integrators tighter control over which quote sources are returned.
