### Improvements
* (x/evm) [\#181](https://github.com/ChainSafe/ethermint/issues/181) Updated EVM module to the recommended module structure. [@fedekunze](https://github.com/fedekunze)
* (app) [\#188](https://github.com/ChainSafe/ethermint/issues/186) Misc cleanup [@fedekunze](https://github.com/fedekunze):
* (`x/evm`) Rename `EthereumTxMsg` --> `MsgEthereumTx` and `EmintMsg` --> `MsgEthermint` for consistency with SDK standards
* Updated integration and unit tests to use `EthermintApp` as testing suite
* Use expected keeper interface for `AccountKeeper`
* Replaced `count` type in keeper with `int`
* Add SDK events for transactions
* [\#236](https://github.com/ChainSafe/ethermint/pull/236) Changes from upgrade [@fedekunze](https://github.com/fedekunze)
* (app/ante) Moved `AnteHandler` implementation to `app/ante`
* (keys) Marked `ExportEthKeyCommand` as **UNSAFE**
* (x/evm) Moved `BeginBlock` and `EndBlock` to `x/evm/abci.go`
