func NewDynamicFeeChecker ¶
func NewDynamicFeeChecker(k interfaces.DynamicFeeEVMKeeper) anteutils.TxFeeChecker
NewDynamicFeeChecker returns a `TxFeeChecker` that applies a dynamic fee to Cosmos txs using the EIP-1559 fee market logic. This can be called in both CheckTx and deliverTx modes. a) feeCap = tx.fees / tx.gas b) tipFeeCap = tx.MaxPriorityPrice (default) or MaxInt64 - when `ExtensionOptionDynamicFeeTx` is omitted, `tipFeeCap` defaults to `MaxInt64`. - when london hardfork is not enabled, it falls back to SDK default behavior (validator min-gas-prices). - Tx priority is set to `effectiveGasPrice / DefaultPriorityReduction`.
Types ¶
type AspectRuntimeContextDecorator ¶
type AspectRuntimeContextDecorator struct {
// contains filtered or unexported fields
}
CreateAspectRuntimeContextDecorator prepare the aspect runtime context
func NewAspectRuntimeContextDecorator ¶
func NewAspectRuntimeContextDecorator(app *baseapp.BaseApp, ek interfaces.EVMKeeper) AspectRuntimeContextDecorator

func (AspectRuntimeContextDecorator) AnteHandle ¶
func (aspd AspectRuntimeContextDecorator) AnteHandle(ctx cosmos.Context, tx cosmos.Tx, simulate bool, next cosmos.AnteHandler) (newCtx cosmos.Context, err error)
AnteHandle validates checks that the registered chain id is the same as the one on the message, and that the signer address matches the one defined on the message. It's not skipped for RecheckTx, because it set `From` address which is critical from other ante handler to work. Failure in RecheckTx will prevent tx to be included into block, especially when CheckTx succeed, in which case user won't see the error message.
type CanTransferDecorator ¶
type CanTransferDecorator struct {
// contains filtered or unexported fields
}
CanTransferDecorator checks if the sender is allowed to transfer funds according to the EVM block context rules.
func NewCanTransferDecorator ¶
func NewCanTransferDecorator(evmKeeper interfaces.EVMKeeper) CanTransferDecorator
NewCanTransferDecorator creates a new CanTransferDecorator instance. NOTE: If this decorator is enabled, place it after the AspectRuntimeContextDecorator.
func (CanTransferDecorator) AnteHandle ¶
func (ctd CanTransferDecorator) AnteHandle(ctx cosmos.Context, tx cosmos.Tx, simulate bool, next cosmos.AnteHandler) (cosmos.Context, error)
AnteHandle creates an EVM from the message and calls the BlockContext CanTransfer function to see if the address can execute the transaction.
type EthAccountVerificationDecorator ¶
type EthAccountVerificationDecorator struct {
// contains filtered or unexported fields
}
EthAccountVerificationDecorator validates an account balance checks
func NewEthAccountVerificationDecorator ¶
func NewEthAccountVerificationDecorator(ak evmmodule.AccountKeeper, ek interfaces.EVMKeeper) EthAccountVerificationDecorator

func (EthAccountVerificationDecorator) AnteHandle ¶
func (avd EthAccountVerificationDecorator) AnteHandle( ctx cosmos.Context, tx cosmos.Tx, simulate bool, next cosmos.AnteHandler, ) (newCtx cosmos.Context, err error)
AnteHandle validates checks that the sender balance is greater than the total transaction cost. The account will be set to store if it doesn't exist, i.e. cannot be found on store. This AnteHandler decorator will fail if: - any of the msgs is not a MsgEthereumTx - from address is empty - account balance is lower than the transaction cost
type EthEmitEventDecorator ¶
type EthEmitEventDecorator struct {
// contains filtered or unexported fields
}
EthEmitEventDecorator emit events in ante handler in case of tx execution failed (out of block gas limit).
func NewEthEmitEventDecorator ¶
func NewEthEmitEventDecorator(evmKeeper interfaces.EVMKeeper) EthEmitEventDecorator
NewEthEmitEventDecorator creates a new EthEmitEventDecorator
func (EthEmitEventDecorator) AnteHandle ¶
func (eeed EthEmitEventDecorator) AnteHandle(ctx cosmos.Context, tx cosmos.Tx, simulate bool, next cosmos.AnteHandler) (newCtx cosmos.Context, err error)
AnteHandle emits some basic events for the eth messages
type EthGasConsumeDecorator ¶
type EthGasConsumeDecorator struct {
// contains filtered or unexported fields
}
EthGasConsumeDecorator validates enough intrinsic gas for the transaction and gas consumption.
func NewEthGasConsumeDecorator ¶
func NewEthGasConsumeDecorator( bankKeeper anteutils.BankKeeper, distributionKeeper anteutils.DistributionKeeper, evmKeeper interfaces.EVMKeeper, stakingKeeper anteutils.StakingKeeper, maxGasWanted uint64, ) EthGasConsumeDecorator
NewEthGasConsumeDecorator creates a new EthGasConsumeDecorator
func (EthGasConsumeDecorator) AnteHandle ¶
func (egcd EthGasConsumeDecorator) AnteHandle(ctx cosmos.Context, tx cosmos.Tx, simulate bool, next cosmos.AnteHandler) (cosmos.Context, error)
AnteHandle validates that the Ethereum tx message has enough to cover intrinsic gas (during CheckTx only) and that the sender has enough balance to pay for the gas cost. If the balance is not sufficient, it will be attempted to withdraw enough staking rewards for the payment.
Intrinsic gas for a transaction is the amount of gas that the transaction uses before the transaction is executed. The gas is a constant value plus any cost incurred by additional bytes of data supplied with the transaction.
This AnteHandler decorator will fail if: - the message is not a MsgEthereumTx - sender account cannot be found - transaction's gas limit is lower than the intrinsic gas - user has neither enough balance nor staking rewards to deduct the transaction fees (gas_limit * gas_price) - transaction or block gas meter runs out of gas - sets the gas meter limit - gas limit is greater than the block gas meter limit
type EthIncrementSenderSequenceDecorator ¶
type EthIncrementSenderSequenceDecorator struct {
// contains filtered or unexported fields
}
EthIncrementSenderSequenceDecorator increments the sequence of the signers.
func NewEthIncrementSenderSequenceDecorator ¶
func NewEthIncrementSenderSequenceDecorator(ak evmmodule.AccountKeeper) EthIncrementSenderSequenceDecorator
NewEthIncrementSenderSequenceDecorator creates a new EthIncrementSenderSequenceDecorator.
func (EthIncrementSenderSequenceDecorator) AnteHandle ¶
func (issd EthIncrementSenderSequenceDecorator) AnteHandle(ctx cosmos.Context, tx cosmos.Tx, simulate bool, next cosmos.AnteHandler) (cosmos.Context, error)
AnteHandle handles incrementing the sequence of the signer (i.e. sender). If the transaction is a contract creation, the nonce will be incremented during the transaction execution and not within this AnteHandler decorator.
type EthMempoolFeeDecorator ¶
type EthMempoolFeeDecorator struct {
// contains filtered or unexported fields
}
EthMempoolFeeDecorator will check if the transaction's effective fee is at least as large as the local validator's minimum gasFee (defined in validator config). If fee is too low, decorator returns error and tx is rejected from mempool. Note this only applies when ctx.CheckTx = true If fee is high enough or not CheckTx, then call next AnteHandler CONTRACT: Tx must implement FeeTx to use MempoolFeeDecorator
func NewEthMempoolFeeDecorator ¶
func NewEthMempoolFeeDecorator(ek interfaces.EVMKeeper) EthMempoolFeeDecorator
NewEthMempoolFeeDecorator creates a new NewEthMempoolFeeDecorator instance used only for Ethereum transactions.
func (EthMempoolFeeDecorator) AnteHandle ¶
func (mfd EthMempoolFeeDecorator) AnteHandle(ctx cosmos.Context, tx cosmos.Tx, simulate bool, next cosmos.AnteHandler) (newCtx cosmos.Context, err error)
AnteHandle ensures that the provided fees meet a minimum threshold for the validator. This check only for local mempool purposes, and thus it is only run on (Re)CheckTx. The logic is also skipped if the London hard fork and EIP-1559 are enabled.
type EthMinGasPriceDecorator ¶
type EthMinGasPriceDecorator struct {
// contains filtered or unexported fields
}
EthMinGasPriceDecorator will check if the transaction's fee is at least as large as the MinGasPrices param. If fee is too low, decorator returns error and tx is rejected. This applies to both CheckTx and DeliverTx and regardless if London hard fork or fee market params (EIP-1559) are enabled. If fee is high enough, then call next AnteHandler
func NewEthMinGasPriceDecorator ¶

AnteHandle ensures that the effective fee from the transaction is greater than the minimum global fee, which is defined by the MinGasPrice (parameter) * GasLimit (tx argument).
type EthSetupContextDecorator ¶

// contains filtered or unexported fields
}

AnteHandle validates checks that the registered chain id is the same as the one on the message, and that the signer address matches the one defined on the message. It's not skipped for RecheckTx, because it set `From` address which is critical from other ante handler to work. Failure in RecheckTx will prevent tx to be included into block, especially when CheckTx succeed, in which case user won't see the error message.
