|
||||
* (`x/evm`) [\#255](https://github.com/ChainSafe/ethermint/pull/255) Add missing `GenesisState` fields and support `ExportGenesis` functionality.
|
||||
* [\#272](https://github.com/ChainSafe/ethermint/pull/272) Add `Logger` for evm module.
|
||||
* [\#317](https://github.com/ChainSafe/ethermint/pull/317) `GenesisAccount` validation.
|
||||
* (`x/evm`) [\#319](https://github.com/ChainSafe/ethermint/pull/319) Verious evm improvements:
|
||||
* Add transaction `[]*ethtypes.Logs` to evm's `GenesisState` to persist logs after an upgrade.
|
||||
* Remove evm `CodeKey` and `BlockKey`in favor of a prefix `Store`.
|
||||
* Set `BlockBloom` during `EndBlock` instead of `BeginBlock`.
|
||||
* `Commit` state object and `Finalize` storage after `InitGenesis` setup.

### Bug Fixes
|
||||
|
||||
* (`x/evm`) [\#319](https://github.com/ChainSafe/ethermint/pull/319) Fix `SetBlockHash` that was setting the incorrect height during `BeginBlock`.
|
||||
* (x/evm) [\#176](https://github.com/ChainSafe/ethermint/issues/176) Updated Web3 transaction hash from using RLP hash. Now all transaction hashes exposed are amino hashes.
|
||||
* Removes `Hash()` (RLP) function from `MsgEthereumTx` to avoid confusion or misuse in future.
