Types ¶
type Constructor ¶
type Constructor func( blockCtx vm.BlockContext, txCtx vm.TxContext, stateDB *statedb.StateDB, chainConfig *params.ChainConfig, config vm.Config, customPrecompiles PrecompiledContracts, ) EVM
Constructor defines the function used to instantiate the EVM on each state transition.

}
EVM defines the interface for the Ethereum Virtual Machine used by the EVM module.
type PrecompiledContracts ¶
type PrecompiledContracts map[common.Address]vm.PrecompiledContract
PrecompiledContracts defines a map of address -> precompiled contract
