Variables

var ChainID = big.NewInt(1337)

ChainID is the chain id used for simulated backends

var TestAddress = crypto.PubkeyToAddress(TestKey.PublicKey)

var TestKey, _ = crypto.HexToECDSA("b71c71a67e1177ad4e901695e1b4b9ee17ae16c6668d313eac2f96dbcda3f291")

TestKey is the same test key that geth uses

Functions

func DeployWithDeterministicDeployer

func DeployWithDeterministicDeployer(backend *backends.SimulatedBackend, contractName string) ([]byte, error)

DeployWithDeterministicDeployer deploys a smart contract on a simulated Ethereum blockchain using a deterministic deployment proxy (Arachnid's).

Parameters: - backend: A pointer to backends.SimulatedBackend, representing the simulated Ethereum blockchain. Expected to have Arachnid's proxy deployer predeploys at 0x4e59b44847b379578588920cA78FbF26c0B4956C, NewL2BackendWithChainIDAndPredeploys handles this for you. - contractName: A string representing the name of the contract to be deployed.

Returns: - []byte: The deployed bytecode of the contract. - error: An error object indicating any issues encountered during the deployment process.

The function logs a fatal error and exits if there are any issues with transaction mining, if the deployment fails, or if the deployed bytecode is not found at the computed address.

func NewBackendWithGenesisTimestamp

func NewBackendWithGenesisTimestamp(chainID *big.Int, ts uint64, shanghai bool, predeploys map[string]*common.Address) (*backends.SimulatedBackend, error)

func NewL1Backend

func NewL1Backend() (*backends.SimulatedBackend, error)

NewL1Backend returns a SimulatedBackend suitable for L1. It has the latest L1 hardforks enabled.

func NewL2Backend

func NewL2Backend() (*backends.SimulatedBackend, error)

NewL2Backend returns a SimulatedBackend suitable for L2. It has the latest L2 hardforks enabled.

func NewL2BackendWithChainIDAndPredeploys

func NewL2BackendWithChainIDAndPredeploys(chainID *big.Int, predeploys map[string]*common.Address) (*backends.SimulatedBackend, error)

NewL2BackendWithChainIDAndPredeploys returns a SimulatedBackend suitable for L2. It has the latest L2 hardforks enabled, and allows for the configuration of the network's chain ID and predeploys.
