Kava 14 Release Candidate 1 (v0.24.0-alpha.0)

Release Candidate for Kava 14

For deployment to Kava Testnet at height 5886355 around 2023-06-23 00:00:00 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.

Note: This is a release candidate only. Do not attempt to run this software on mainnet.

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.

v0.23.2

This is an optional and non-breaking release. Displays an error instead of a panic in certain cases, such as when attempting to run an export when another kava instance is running.

Bug Fixes

• (deps) #1622 Bump tm-db to v0.6.7-kava.3 to return rocksdb errors on open

v0.23.1 - Kava 13 IBC Security Patch

This upgrade follows https://forum.cosmos.network/t/ibc-security-advisory-huckleberry/10731 and updates IBC from v6.1.0 to v6.1.1.

This is a non-state breaking change and may be applied at any time.

v0.21.1

This release adds a grpc query service to the x/incentive module.

Kava 12 Release

For deployment to Kava Mainnet scheduled on Feburary 15th, 2023 at block 3607200.
See upgrade instructions at https://github.com/Kava-Labs/kava/blob/v0.21.0/migrate/v0_21/migrate.md.

This release candidate adds a x/community module that is used to manage community pool funds via governance by Kava DAO. It includes additional enhancements to the EVM.

Software versions:
Golang: v1.18.10 (using a version other than 1.18 will result in app hash mismatches. v1.18 MUST be used.)
Cosmos-sdk: v0.45.10
Tendermint: v0.34.24

x/community

• includes two gov proposals for deposit/withdraw of community pool funds to Kava Lend (x/hard)

EVM enhancements

• ethermint updated
• Allows 'finalized' to be used on eth json rpc calls
• Fixes eth_call for old heights (prevent panic on GetParams before allowed EIP messages were set)

Kava 12 Release Candidate 3 (v0.21.0-alpha.1)

Fixes a problem on testnet where previous version history in the IAVL tree of the x/mint store caused panics on chain upgrade. The problem happens for any cosmos-sdk module that is added with the same store key as a previously removed module (x/mint in the case of Kava Testnet 16000).

A fix was added to the v0.21.0-alpha.0 upgrade handler to remove all pre-existing tree state for the x/mint module so it can be added anew from a clean state. A side effect of this is that historic state of the x/mint module will not be query-able on Kava Testnet.

No changes or side effects of this change affect mainnet. The v0.21.0 upgrade handler expected to run for the Kava 12 release remains unchanged.

Kava 12 Release Candidate 2 (v0.21.0-alpha.0)

Release Candidate for Kava 12

For deployment to Kava Testnet on 31 Jan, 2023.

This release candidate adds a x/community module that is used to manage community pool funds via governance by Kava DAO. It includes additional enhancements to the EVM.

Software versions:
Golang: v1.18 (using a version other than 1.18 will result in app hash mismatches. v1.18 MUST be used.)
Cosmos-sdk: v0.45.10
Tendermint: v0.34.24

It contains two upgrade handlers:

• v0.21.0-alpha.0 - To be run on testnet. Rolls back state changes made in abandoned upgrade v0.20.0-alpha.0. Upgrades chain to the proposed Kava 12 state.
• v0.21.0 - To be run on mainnet. Upgrades the chain to Kava 12.

x/community

• includes two gov proposals for deposit/withdraw of community pool funds to Kava Lend (x/hard)

EVM enhancements

• ethermint updated
• Allows 'finalized' to be used on eth json rpc calls
• Fixes eth_call for old heights (prevent panic on GetParams before allowed EIP messages were set)
