Functions ¶
func GetPrecompiles ¶
func GetPrecompiles(cfg *params.ChainConfig, blockNumber *big.Int) evm.PrecompiledContracts
GetPrecompiles returns all the precompiled contracts defined given the current chain configuration and block height.
func NewEVM ¶
func NewEVM( blockCtx vm.BlockContext, txCtx vm.TxContext, stateDB vm.StateDB, chainConfig *params.ChainConfig, config vm.Config, _ evm.PrecompiledContracts, ) evm.EVM
NewEVM defines the constructor function for the go-ethereum (geth) EVM. It uses the default precompiled contracts and the EVM concrete implementation from geth.
Types ¶
type EVM ¶
EVM is the wrapper for the go-ethereum EVM.
func (EVM) ActivePrecompiles ¶
ActivePrecompiles returns a list of all the active precompiled contract addresses for the current chain configuration.
func (EVM) Precompile ¶
Precompile returns the precompiled contract associated with the given address and the current chain configuration. If the contract cannot be found it returns nil.
func (EVM) RunPrecompiledContract ¶
func (EVM) RunPrecompiledContract( p evm.StatefulPrecompiledContract, _ common.Address, input []byte, suppliedGas uint64, _ *big.Int, ) (ret []byte, remainingGas uint64, err error)
RunPrecompiledContract runs a stateless precompiled contract and ignores the address and value arguments. It uses the RunPrecompiledContract function from the geth vm package.
