Abstract

EVM module was copy-pasted from evmos/ethermint project. The goal of EVM module is to provide Solidity smart contracts support into the Cosmos-based core.

You can find the full specification for that module here: https://github.com/rarimo/rarimo-core/tree/master/x/evm/spec Also, EVM module works in couple with feemarket module that has been designed to support EIP1559 in Cosmos-SDK. The feemarket module doc: https://github.com/rarimo/rarimo-core/tree/master/x/feemarket/spec.

Notes

Accounts

To use Cosmos accounts in EVM the basic go implementation (Cosmos BaseAccount) was replaced with ethermint.EthAccount. All accounts generated by CLI or created on-chain by token transfer will be stored in that wrapper.

Ports

Use app.toml to edit the following EVM configuration:

  • Address defines the EVM RPC HTTP server address to bind to.

    address = "0.0.0.0:8545"

  • Address defines the EVM WebSocket server address to bind to.

    ws-address = "0.0.0.0:8546"

	data types.GenesisState,
) []abci.ValidatorUpdate

InitGenesis initializes genesis state based on exported genesis

func NewHandler 

func NewHandler(server types.MsgServer) sdk.Handler

NewHandler returns a handler for Ethermint type messages.

Types

type AppModule 

type AppModule struct {
	AppModuleBasic
	// contains filtered or unexported fields
}

AppModule implements an application module for the evm module.

func NewAppModule 

func NewAppModule(k *keeper.Keeper, ak types.AccountKeeper, ss types.Subspace) AppModule

NewAppModule creates a new AppModule object

func (AppModule) BeginBlock 

func (am AppModule) BeginBlock(ctx sdk.Context, req abci.RequestBeginBlock)

BeginBlock returns the begin block for the evm module.

func (AppModule) EndBlock 

func (am AppModule) EndBlock(ctx sdk.Context, req abci.RequestEndBlock) []abci.ValidatorUpdate

EndBlock returns the end blocker for the evm module. It returns no validator updates.

func (AppModule) ExportGenesis 

func (am AppModule) ExportGenesis(ctx sdk.Context, cdc codec.JSONCodec) json.RawMessage

ExportGenesis returns the exported genesis state as raw bytes for the evm module.

func (AppModule) GenerateGenesisState 

func (AppModule) GenerateGenesisState(_ *module.SimulationState)

GenerateGenesisState creates a randomized GenState of the evm module.

func (AppModule) InitGenesis 

func (am AppModule) InitGenesis(ctx sdk.Context, cdc codec.JSONCodec, data json.RawMessage) []abci.ValidatorUpdate

InitGenesis performs genesis initialization for the evm module. It returns no validator updates.

func (AppModule) LegacyQuerierHandler 

func (am AppModule) LegacyQuerierHandler(_ *codec.LegacyAmino) sdk.Querier

LegacyQuerierHandler returns nil as the evm module doesn't expose a legacy Querier.

func (AppModule) Name 

func (AppModule) Name() string

Name returns the evm module's name.

func (AppModule) ProposalContents 

func (AppModule) ProposalContents(_ module.SimulationState) []simtypes.WeightedProposalContent

func (AppModule) QuerierRoute() string

QuerierRoute returns the evm module's querier route name.

func (AppModule) RandomizedParams 

func (AppModule) RandomizedParams(_ *rand.Rand) []simtypes.ParamChange

RandomizedParams creates randomized evm param changes for the simulator.

func (AppModule) RegisterInvariants 

func (am AppModule) RegisterInvariants(_ sdk.InvariantRegistry)

RegisterInvariants interface for registering invariants. Performs a no-op as the evm module doesn't expose invariants.
