Changelog

Unreleased

(keys) #554 Fix private key derivation.
(app/ante) #550 Update ante handler nonce verification to accept any nonce greater than or equal to the expected nonce to allow to successive transactions.

(app) #540 Chain identifier's format has been changed to match the Cosmos chainID standard, which is required for IBC. The epoch number of the ID is used as the EVM chainID.

(types) #503 The types.DenomDefault constant for "aphoton" has been renamed to types.AttoPhoton.

(types) #504 Unmarshal a JSON EthAccount using an Ethereum hex address in addition to Bech32.
(types) #503 Add --coin-denom flag to testnet command that sets the given coin denomination to SDK and Ethermint parameters.
(types) #502 EthAccount now also exposes the Ethereum hex address in string format to clients.
(types) #494 Update EthAccount public key JSON type to string.
(app) #471 Add x/upgrade module for managing software updates.
(x/evm) #458 Define parameter for token denomination used for the EVM module.
(x/evm) #443 Support custom Ethereum ChainConfig params.
(types) #434 Update default denomination to Atto Photon (aphoton).
(types) #515 Update minimum gas price to be 1.

(ante) #525 Add message validation decorator to AnteHandler for MsgEthereumTx.
(types) #507 Fix hardcoded aphoton on EthAccount balance getter and setter.
(types) #501 Fix bech32 encoding error by using the compressed ethereum secp256k1 public key.
(x/evm) #496 Fix bugs on journal.revert and CommitStateDB.Copy.
(types) #480 Update BIP44 coin type to 60 to satisfy EIP84.
(types) #513 Fix simulated transaction bug that was causing a consensus error by unintentionally affecting the state.

(sdk) #386 Bump Cosmos SDK version to v0.39.1
(x/evm) #181 Updated EVM module to the recommended module structure.
(app) #188 Misc cleanup:
- (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 Changes from upgrade:
- (app/ante) Moved AnteHandler implementation to app/ante
- (keys) Marked ExportEthKeyCommand as UNSAFE
- (x/evm) Moved BeginBlock and EndBlock to x/evm/abci.go
(x/evm) #255 Add missing GenesisState fields and support ExportGenesis functionality.
#272 Add Logger for evm module.
#317 GenesisAccount validation.
(x/evm) #319 Various evm improvements:
- Add transaction []*ethtypes.Logs to evm's GenesisState to persist logs after an upgrade.
- Remove evm CodeKey and BlockKeyin favor of a prefix Store.
- Set BlockBloom during EndBlock instead of BeginBlock.
- Commit state object and Finalize storage after InitGenesis setup.
(rpc) #325 eth_coinbase JSON-RPC query now returns the node's validator address.

(build) #378 Create multi-node, local, automated testnet setup with make localnet-start.
(rpc) #330 Implement PublicFilterAPI's EventSystem which subscribes to Tendermint events upon Filter creation.
(rpc) #231 Implement NewBlockFilter in rpc/filters.go which instantiates a polling block filter
- Polls for new blocks via BlockNumber rpc call; if block number changes, it requests the new block via GetBlockByNumber rpc call and adds it to its internal list of blocks
- Update uninstallFilter and getFilterChanges accordingly
- uninstallFilter stops the polling goroutine
- getFilterChanges returns the filter's internal list of block hashes and resets it
(rpc) #54, #55 Implement eth_getFilterLogs and eth_getLogs:
- For a given filter, look through each block for transactions. If there are transactions in the block, get the logs from it, and filter using the filterLogs method
- eth_getLogs and eth_getFilterChanges for log filters use the same underlying method as eth_getFilterLogs
- update HandleMsgEthereumTx to store logs using the ethereum hash
(app) #187 Add support for simulations.

(rpc) #305 Update eth_getTransactionCount to check for account existence before getting sequence and return 0 as the nonce if it doesn't exist.
(x/evm) #319 Fix SetBlockHash that was setting the incorrect height during BeginBlock.
(x/evm) #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.
