Functions

func CanTransfer

func CanTransfer(db vm.StateDB, addr common.Address, amount *uint256.Int) bool

CanTransfer is overridden to explicitly allow all transfers in the monomer EVM. This avoids needing to deal with account balances.

func NewEVM

func NewEVM(ethState vm.StateDB, header *monomer.Header) (*vm.EVM, error)

Types

type CallParams

type CallParams struct {
	Sender *common.Address
	Value  *big.Int
	Data   []byte
}

type MonomerContractExecuter

type MonomerContractExecuter struct {
	ABI *gethabi.ABI
	// contains filtered or unexported fields
}

func NewMonomerContractExecuter

func NewMonomerContractExecuter(evm *vm.EVM, abiJSON string, contractAddr common.Address) (*MonomerContractExecuter, error)

func (*MonomerContractExecuter) Call

func (e *MonomerContractExecuter) Call(params *CallParams) ([]byte, error)
