Functions

func CanTransfer

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

CanTransfer checks whether there are enough funds in the address' account to make a transfer. This does not take the necessary gas into account to make the transfer valid.

func GetHashFn

func GetHashFn(ref *types.Header, chain chainContext) func(uint64) common.Hash

GetHashFn returns a GetHashFunc which retrieves header hashes by number

func New

func New(from common.Address, gasPrice *big.Int, header *types.Header, chain chainContext, txFeeRecipient *common.Address) vm.BlockContext

New creates a new context for use in the EVM.

func NewEVMRunner

func NewEVMRunner(chain evmRunnerContext, header *types.Header, state vm.StateDB) vm.EVMRunner
