Software upgrade being scheduled with this proposal

If successful, this proposal will schedule an Evmos mainnet software upgrade at block height 14,538,200 (around 4pm UTC Wed., 12th July 2023) from its current version v12.1.6 to v13.0.2 (Apeiron). This proposal has a voting time of 120 hours.

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

Evmos v13.0.2 (Apeiron) contains the following changes and enhancements:

• Introduce EVM extensions for staking, distribution and IBC transfers
• Upgrade CometBFT to v0.34.29 and Cosmos SDK to v0.46.11
• Many small improvements and refactors

A full changelog can be found here.

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. On top of the upgrade tests, the Evmos team runs performance tests to monitor the impact of new versions.
