Types

type PrecompiledContract

type PrecompiledContract interface {
	RequiredGas(input []byte) uint64                                                    // RequiredPrice calculates the contract gas use
	Run(evm *vm.EVM, snapshot int, contract *vm.Contract, input []byte) ([]byte, error) // Run runs the precompiled contract
}

PrecompiledContract is the basic interface for native Go contracts. The implementation requires a deterministic gas count based on the input size of the Run method of the contract.
