func DialRollupClientWithTimeout

func DialRollupClientWithTimeout(ctx context.Context, url string) (*sources.RollupClient, error)

DialRollupClientWithTimeout attempts to dial the RPC provider using the provided URL. If the dial doesn't complete within defaultDialTimeout seconds, this method will return an error.

func NewCallOptsWithSender

func NewCallOptsWithSender(ctx context.Context, sender common.Address) *bind.CallOpts

func NewSimpleCallOpts

func NewSimpleCallOpts(ctx context.Context) *bind.CallOpts

func NewSimpleTxOpts

func NewSimpleTxOpts(ctx context.Context, from common.Address, signerFn crypto.SignerFn) *bind.TransactOpts

func NewSimpleWatchOpts

func NewSimpleWatchOpts(ctx context.Context) *bind.WatchOpts

func ParseAddress

func ParseAddress(address string) (common.Address, error)

ParseAddress parses an ETH address from a hex string. This method will fail if the address is not a valid hexadecimal address.
