Software upgrade being scheduled with this proposal

If successful, this proposal will schedule an Evmos Mainnet software upgrade at block height 9,495,000 from its current version v9.1.0 to v10.0.0. This proposal has a voting time of 5 days.

Motivation

By proposing a scheduled upgrade, we want to implement a smooth and transparent upgrade process, that is first proposed on Testnet and then on Mainnet. Software upgrades generally aim to improve current performance and add new features to the Evmos chain. For more information on the types of upgrades, please visit our Software Upgrade Guide.

Impact

On a high level, the v10.0.0 software includes the following improvements:

• Update Cosmos-SDK to v0.46.7, IBC-Go to v5.2.0 and Ethermint to v0.20.0
• Automatic conversion of IBC coins to their ERC20 representation upon receiving
• Support for ERC20 token transfers via IBC
• ERC20 proposals to register ERC20 tokens and Cosmos coins now can receive multiple denominations
• Prioritized mempool support for Cosmos and Ethereum txs
• EIP-1559 support for native Cosmos transactions
• EIP-712 fixes for all major Cosmos messages (eg: MsgGrant for restake support)
• Add Ledger support to the evmosd CLI
• Ethereum Tx indexer
• The funder for a clawback vesting account can now be updated
• Introduce minimum commission rate as governance ruled parameter for the staking module (set at 5%)
• EIP-712 fixes for the vesting module
• Add a default file store listener for a basic implementation of ADR-038: State Listening
• Update default node snapshot interval to 5000 seconds
• Update Ledger supported algorithms to only consist of EthSecp256k1

NOTE: Since Cosmos v0.46 it is not possible to include links to Windows binaries in software upgrade proposals anymore.

Testing

The Evmos core team created an End-to-End testing suite that performs the software upgrade locally. These tests have been completed successfully for this upgrade. The instructions on how to run the End-to-End testing suite can be found here. Additionally, the upgrade has been manually performed on a local node.
