v0.24.1

This is a non-breaking release. Node operators are encouraged to apply the update at their earliest convenience.

The update includes a new query endpoint for x/community to calculate annualized staking rewards in preparation for an upcoming change to how staking rewards are calculated. See migrate/staking_rewards.md for full details.

Additionally, this release includes custom & performance timing metrics that are emitted when telemetry is enabled.

Kava 14 Release (v0.24.0)

Kava 14 Release

For deployment to Kava Mainnet scheduled for height 5597000 and estimated to occur at 2023-07-12 15:00:00 UTC.

This release adds the ability to convert between a cosmos-native asset (sdk.Coin) and an ERC20 representation of the asset in the EVM. The assets allowed for conversion can be controlled by Kava DAO via a new parameter to the x/evmutil module.

Software versions:
Golang: v1.20
Cosmos-sdk: v0.46.11
CometBFT: v0.34.27 (formerly Tendermint)

For a complete list of changes, including client breaking changes, see CHANGELOG.md.

Cosmos Coin <=> ERC20 Conversion

For a technical overview of conversion, see the "Cosmos-Native Assets" section of the x/evmutil spec.

Allowed assets

Kava DAO controls which assets are allow-listed for conversion via a new x/evmutil parameter, allowed_cosmos_denoms.

The upgrade handlers included in this release initialize the parameter:

• The Testnet upgrade handler, v0.24.0-alpha.0, allows HARD tokens (hard) to be converted to an ERC20
• The Mainnet upgrade handler, v0.24.0, allows ATOM (ibc/27394FB092D2ECCD56123C74F36E4C1F926001CEADA9CA97EA622B25F41E5EB2) to be converted

New Messages

Conversion is managed via two new messages:

• MsgConvertCosmosCoinToERC20 performs the conversion from Cosmos coin to ERC20. ERC20 contracts are deployed and owned by the x/evmutil module account, and are deployed on first conversion.
• MsgConvertCosmosCoinFromERC20 converts the ERC20 back to the underlying Cosmos coin.

Enumerating Cosmos Coin ERC20 Contracts

A new x/evmutil query is added for enumerating deployed contracts: /kava/evmutil/v1beta1/deployed_cosmos_coin_contracts.

v0.23.3

This is an optional and non-breaking release.

Includes a patch to cometbft that prevents a snappy encode panic when starting a chain with a large ~4GiB+ genesis file and goleveldb as the database backend.

Bug Fixes

• (deps) #1631 Bump cometbft to v0.34.27-kava.0
