Summary

  • Main Feature: Bundle builder state machine improvements
    • Rewrite the state machine to support "cancellations." A cancellation occurs when the bundler receives a "replacement underpriced" error from a node, but it believes its submitting a fair gas price and there are current UOs that pay this gas price. Previously, the bundler would get stuck in this state and UOs that pay fair gas wouldn't get mined. It was possible to get into this price if a bundle was submitted with a high priority fee, but wasn't mined, and is blocking the bundler's nonce. The bundler now detects this state and attempts to remedy it with a transaction cancellation.
    • There are two types of cancellations: hard and soft. Some RPCs support soft cancellations which allow the sender to cancel and existing transaction without issuing a replacement (i.e. Flashbots). Hard cancellations require a replacement transaction and cost tokens.
    • Remove maximum fee increases from bundle submission - if a UO is paying enough gas to be included in a bundle it should. Maximum fee increases still applies to hard cancellation transactions.
    • Remove transaction status polling from the tracker, the state machine runs completely off of a defined trigger - either a new block or a timeout.
    • Add time to mine tracking and metrics.
  • Chain support:
    • Add support for Avalanche
    • Ban access to Arbitrum Stylus contracts without whitelist
    • Remove Goerli networks
  • Bug fixes:
    • Fix race condition in paymaster tracking.
    • Fix error message for unstaked entity mempool count.
    • Raise Polygon Amoy chain configuration min fee to 30 gwei.
    • Add a timeout of 10s to the tracer calls.
  • Small Features:
    • Allow for multiple private keys to be configured.
    • Allow staked senders to have multiple UOs per bundle.
    • Check for total gas limit exceeded after estimation.
    • Remove ops from pool if condition is not met when using conditional RPC.
    • Update to Rust v1.79.0
    • Fix transaction sender's support of transaction status across various provider types.
