func GasToRefund

func GasToRefund(availableRefund, gasConsumed, refundQuotient uint64) uint64

GasToRefund calculates the amount of gas the state machine should refund to the sender. It is capped by the refund quotient value. Note: do not pass 0 to refundQuotient

) (sdk.Coins, error)

Types

type Keeper

type Keeper struct {
	// contains filtered or unexported fields
}

Keeper grants access to the EVM module state and implements the go-ethereum StateDB interface.

func NewKeeper

func NewKeeper(
	cdc codec.BinaryCodec,
	storeKey, transientKey storetypes.StoreKey,
	authority sdk.AccAddress,
	ak types.AccountKeeper,
	bankKeeper types.BankKeeper,
	sk types.StakingKeeper,
	fmk types.FeeMarketKeeper,
	tracer string,
	ss paramstypes.Subspace,
) *Keeper

NewKeeper generates new evm module keeper

func (Keeper) Account

Account implements the Query/Account gRPC method

func (Keeper) AddTransientGasUsed

func (k Keeper) AddTransientGasUsed(ctx sdk.Context, gasUsed uint64) (uint64, error)

func (*Keeper) ApplyMessage

func (k *Keeper) ApplyMessage(ctx sdk.Context, msg core.Message, tracer vm.EVMLogger, commit bool) (*types.MsgEthereumTxResponse, error)

ApplyMessage calls ApplyMessageWithConfig with an empty TxConfig.

func (*Keeper) ApplyMessageWithConfig

func (k *Keeper) ApplyMessageWithConfig(ctx sdk.Context,
	msg core.Message,
	tracer vm.EVMLogger,
	commit bool,
	cfg *statedb.EVMConfig,
	txConfig statedb.TxConfig,
) (*types.MsgEthereumTxResponse, error)

ApplyMessageWithConfig computes the new state by applying the given message against the existing state. If the message fails, the VM execution error with the reason will be returned to the client and the transaction won't be committed to the store.

Reverted state

The snapshot and rollback are supported by the `statedb.StateDB`.

Different Callers

It's called in three scenarios: 1. `ApplyTransaction`, in the transaction processing flow. 2. `EthCall/EthEstimateGas` grpc query handler. 3. Called by other native modules directly.

Prechecks and Preprocessing

All relevant state transition prechecks for the MsgEthereumTx are performed on the AnteHandler, prior to running the transaction against the state. The prechecks run are the following:

1. the nonce of the message caller is correct 2. caller has enough balance to cover transaction fee(gaslimit * gasprice) 3. the amount of gas required is available in the block 4. the purchased gas is enough to cover intrinsic usage 5. there is no overflow when calculating intrinsic gas 6. caller has enough balance to cover asset transfer for **topmost** call

The preprocessing steps performed by the AnteHandler are:

1. set up the initial access list (iff fork > Berlin)

Tracer parameter

It should be a `vm.Tracer` object or nil, if pass `nil`, it'll create a default one based on keeper options.

Commit parameter

If commit is true, the `StateDB` will be committed, otherwise discarded.

func (*Keeper) ApplyTransaction

func (k *Keeper) ApplyTransaction(ctx sdk.Context, tx *ethtypes.Transaction) (*types.MsgEthereumTxResponse, error)

ApplyTransaction runs and attempts to perform a state transition with the given transaction (i.e Message), that will only be persisted (committed) to the underlying KVStore if the transaction does not fail.

Gas tracking

Ethereum consumes gas according to the EVM opcodes instead of general reads and writes to store. Because of this, the state transition needs to ignore the SDK gas consumption mechanism defined by the GasKVStore and instead consume the amount of gas used by the VM execution. The amount of gas used is tracked by the EVM and returned in the execution result.

Prior to the execution, the starting tx gas meter is saved and replaced with an infinite gas meter in a new context in order to ignore the SDK gas consumption config values (read, write, has, delete). After the execution, the gas used from the message execution will be added to the starting gas consumed, taking into consideration the amount of gas returned. Finally, the context is updated with the EVM gas consumed value prior to returning.
