Functions

func ImpersonatedSigner 

func ImpersonatedSigner(address common.Address, transaction *types.Transaction) (*types.Transaction, error)

ImpersonatedSigner is a signer that does nothing for use in account impersonation w/ contracts.

Types

type Backend 

type Backend struct {
	*base.Backend
	// contains filtered or unexported fields
}

Backend contains the anvil test backend.

func NewAnvilBackend 

func NewAnvilBackend(ctx context.Context, t *testing.T, args *OptionBuilder) *Backend

func (*Backend) BackendName 

func (f *Backend) BackendName() string

BackendName returns the name of the backend.

func (*Backend) ChainConfig 

func (f *Backend) ChainConfig() *params.ChainConfig

Note *any* other call made to the backend will impersonate while this is being called in a future version, we'll wrap something like omnirpc to prevent other transactions submission calls from taking place in the meantime, this may cause race conditions.

We also print a warning message to the console as an added precaution.

Signer gets the signer for the chain.
