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 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
	// 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) 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) 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.

func (*Keeper) ForEachStorage

func (k *Keeper) ForEachStorage(ctx sdk.Context, addr ethcmn.Address, cb func(key, value ethcmn.Hash) bool) error

ForEachStorage calls CommitStateDB.ForEachStorage using passed in context

func (Keeper) GenerateCSDBParams

func (k Keeper) GenerateCSDBParams() types.CommitStateDBParams

Logger returns a module-specific logger.

func (Keeper) GetAccountStorage

func (k Keeper) GetAccountStorage(ctx sdk.Context, address common.Address) (types.Storage, error)

GetAccountStorage return state storage associated with an account

func (*Keeper) GetBalance

func (k *Keeper) GetBalance(ctx sdk.Context, addr ethcmn.Address) *big.Int

GetBalance calls CommitStateDB.GetBalance using the passed in context

func (Keeper) GetBlockBloom

func (k Keeper) GetBlockBloom(ctx sdk.Context, height int64) ethtypes.Bloom

GetBlockBloom gets bloombits from block height

func (Keeper) GetBlockHash

func (k Keeper) GetBlockHash(ctx sdk.Context, hash []byte) (int64, bool)

GetBlockHash gets block height from block consensus hash

func (Keeper) GetChainConfig

func (k Keeper) GetChainConfig(ctx sdk.Context) (types.ChainConfig, bool)

GetChainConfig gets block height from block consensus hash

func (*Keeper) GetCode

func (k *Keeper) GetCode(ctx sdk.Context, addr ethcmn.Address) []byte

GetCode calls CommitStateDB.GetCode using the passed in context

func (Keeper) GetHeightHash

func (k Keeper) GetHeightHash(ctx sdk.Context, height uint64) common.Hash

GetHeightHash returns the block header hash associated with a given block height and chain epoch number.

func (k *Keeper) GetOrNewStateObject(ctx sdk.Context, addr ethcmn.Address) types.StateObject

GetOrNewStateObject calls CommitStateDB.GetOrNetStateObject using the passed in context

func (Keeper) GetParams

func (k Keeper) GetParams(ctx sdk.Context) (params types.Params)

GetParams returns the total set of evm parameters.

func (*Keeper) GetState

GetState calls CommitStateDB.GetState using the passed in context

func (Keeper) Logger

func (k Keeper) Logger(ctx sdk.Context) log.Logger

Logger returns a module-specific logger.
