v5.7.0

Changelog

This release introduces new features and several improvements

• Introduced a new on-chain gas estimation method in the gas service.
  • A gas price oracle will be enabled soon to update gas prices on the gas service.
  • L2 specific gas pricing rules are taken into account for Optimism/Base (i.e L1 data fee is automatically added in the gas quote). This will be extended to other L2s, including Arbitrum, in an upcoming release.
• A new payGas method has been added to the gas service that will support all types of gas service methods generically.
  • Example usage: gasService.payGas{value: msg.value}(address(this), destinationChain, destinationAddress, payload, executionGasLimit, estimateOnChain, refundAddress, new bytes(0))
  • params are optional and empty bytes can be provided for now. In the future, params can be used to provide additional context for the gas payment (e.g. pay with an ERC20, enable GMP express etc.)
  • If estimateOnChain is set to true, the gas payment call will revert if msg.value is less than the on-chain gas quote.
• A new InterchainMultisig contract that allows batching calls across many chains.
• Bumped Solidity compiler version to v0.8.23
