Functions

func NewQuerier 

func NewQuerier(keeper Keeper) sdk.Querier

NewQuerier is the module level router for state queries

func RegisterInvariants 

func RegisterInvariants(ir sdk.InvariantRegistry, k Keeper)

RegisterInvariants registers the evm module invariants

Types

type GovKeeper 

type GovKeeper interface {
	GetDepositParams(ctx sdk.Context) govtypes.DepositParams
	GetVotingParams(ctx sdk.Context) govtypes.VotingParams
}

GovKeeper defines the expected gov Keeper

type Keeper 

type Keeper struct {

	// Transaction counter in a block. Used on StateSB's Prepare function.
	// It is reset to 0 every block on BeginBlock so there's no point in storing the counter
	// on the KVStore or adding it as a field on the EVM genesis state.
	TxCount int
	Bloom   *big.Int
	Bhash   ethcmn.Hash
	LogSize uint
	Watcher *watcher.Watcher
	// contains filtered or unexported fields
}

Keeper wraps the CommitStateDB, allowing us to pass in SDK context while adhering to the StateDB interface.

func NewKeeper 

func NewKeeper(
	cdc *codec.Codec, storeKey sdk.StoreKey, paramSpace params.Subspace, ak types.AccountKeeper, sk types.SupplyKeeper, bk bank.Keeper,
) *Keeper

NewKeeper generates new evm module keeper

func (Keeper) AfterDepositPeriodPassed 

func (k Keeper) AfterDepositPeriodPassed(_ sdk.Context, _ govTypes.Proposal)

func (Keeper) AfterSubmitProposalHandler 

func (k Keeper) AfterSubmitProposalHandler(_ sdk.Context, _ govTypes.Proposal)

nolint

func (Keeper) BalanceInvariant 

func (k Keeper) BalanceInvariant() sdk.Invariant

BalanceInvariant checks that all auth module's EthAccounts in the application have the same balance as the EVM one.

func (*Keeper) BeginBlock 

func (k *Keeper) BeginBlock(ctx sdk.Context, req abci.RequestBeginBlock)

BeginBlock sets the block hash -> block height map for the previous block height and resets the Bloom filter and the transaction count to 0.

func (Keeper) CheckMsgSubmitProposal 

func (k Keeper) CheckMsgSubmitProposal(ctx sdk.Context, msg govTypes.MsgSubmitProposal) sdk.Error

CheckMsgSubmitProposal validates MsgSubmitProposal

func (Keeper) EndBlock 

func (k Keeper) EndBlock(ctx sdk.Context, req abci.RequestEndBlock) []abci.ValidatorUpdate

EndBlock updates the accounts and commits state objects to the KV Store, while deleting the empty ones. It also sets the bloom filers for the request block to the store. The EVM end block logic doesn't update the validator set, thus it returns an empty slice.
