Unreleased

0.15.0

  • Fix simulation for broadcaster middleware (#58)
  • Added support for replacementUuid field in eth_sendBundle (#63)
  • Made response's data field optional to support some builders other than Flashbots (#76)

0.14.0

Added

  • Added a broadcaster middleware (#54)

0.13.1

0.12.1

Fixed

  • Handle optional fields in the response of flashbots_getBundleStatsV2.

0.12.0

Added

  • It is now possible to use your own endpoint for simulating bundles. Bundles will be sent over JSON-RPC to the given endpoint. The JSON-RPC method used is eth_callBundle. See Middleware::set_simulation_relay.

Changed

  • The library now uses the new flashbots_getUserStatsV2 and flashbots_getBundleStatsV2 endpoints. If you need the old endpoints, pin your version to 0.11.0.

0.11.0

  • Addd a rustls feature flag to use native TLS over OpenSSL
  • Bumped thiserror to 1.0.37
  • Bumped chrono to 0.4.22
  • Bumped url to 2.3.1
  • Bumped async-trait to 0.1.58
  • Bumped ethers to 1.0.0

0.10.0

  • Replaced anyhow with eyre

0.9.0

Changed

  • Updated to ethers ^0.13.0

0.8.2

Added

  • Debug is now implemented for UserStats and BundleStats

Changed

  • PendingBundle::bundle_hash() is now deprecated

0.8.1

A small patch to fix the documentation on docs.rs.

0.8.0

Added

  • The basefee for a simulated block can now be specified.

0.7.0

Changed

  • Updated to ethers ^0.6.0

0.6.0

Changed

  • Relaxed version requirement for Ethers - version requirement is now ^0.5.0.
  • Disabled default Ethers features to allow for building on Windows (which lacks IPC support, see gakonst/ethers-rs#393)

0.5.0

Added

  • Revert reason is now parsed, if there is any.

Fixed

  • value on a simulated transaction was incorrectly assumed to be the amount of Ether sent in a transaction. It is now correctly parsed as Bytes, since it represents the return data (if any) of the transaction.

0.4.0

Changed

  • Parameters are now validated before bundles are sent to the relay. Check the documentation for more information.
  • Bumped ethers to 0.5.1

Added

  • Added a helper to get the effective gas price of bundles and bundle transactions (SimulatedBundle::effective_gas_price and SimulatedTransaction::effective_gas_price).

0.3.1

Added

  • Added a way to get stats about bundles (FlashbotsMiddleware::get_bundle_stats)
  • Added a getter for the bundle hash of a pending bundle
  • Added a way to get stats about your searcher identity (FlashbotsMiddleware::get_user_stats)

0.3.0

Fixes

  • If your bundle contains a transaction that deploys a contract, the SimulatedTransaction will now have a destination (to) of None to distinguish this from the zero address.

0.2.2

Fixes

  • Handle non-JSONRPC errors from the Flashbots relay

0.2.1

Fixes

  • Correctly serializes bundle requests
