Cosmos EVM v0.3.1 is a patch update with some minor quality of life changes and dependency updates.

What's Changed

• chore: update dependencies on v0.3.x by @aljo242 in #359
• bug: add evm-chain-id to toml.go by @dudong2 in #403
• chore: fix local node script by @canu0205 in #395

Full Changelog: v0.3.0...v0.3.1

This release has been audited by Sherlock. A link to the final audit report can be found here.

The v0.3.0 release includes:

• Upgraded GETH to v1.15
• Permissionless ERC20 registrations on x/bank
• Support for IBC v2 & IBC-Go v10
• Support for Cosmos SDK v0.53.x
• Integrated Kava's x/precisebank to handle varying decimals for gas tokens
• Feemarket for Dynamic Fee transaction support (EIP-1559)
• Removal of the x/authz dependency on precompiles
• Changed erc20/ prefix to erc20: to support IBC v2 specification
• Testing refactor
• Separate Cosmos and EVM chain IDs (no longer required to merge these into one chain-id string)
• x/gov precompile now supports all messages including proposal submission

Our priorities for the next v0.4.0 release are:

• Getting the application-side mempool working
• Spiking all remaining EVM-equivalence unknowns (and fixing high priority ones)
• Setting up a proper benchmarking framework and perform load-testing
