Functions

func AccountToAddress

func AccountToAddress(accounts []types.Account) (addresses []common.Address, err error)

func FilterNamesFromRelayArgs

func FilterNamesFromRelayArgs(args commontypes.RelayArgs) (filterNames []string, err error)

func IsLaterThan

func NewChainReader added in v2.8.0

func NewChainReader(h httypes.HeadTracker) mercurytypes.ChainReader

func NewCodec added in v2.9.0

func NewCodec(conf types.CodecConfig) (commontypes.RemoteCodec, error)

NewCodec creates a new commontypes.RemoteCodec for EVM. Note that names in the ABI are converted to Go names using abi.ToCamelCase, this is per convention in abi.MakeTopics, abi.Arguments.Pack etc. This allows names on-chain to be in go convention when generated. It means that if you need to use a codec.Modifier to reference a field you need to use the Go name instead of the name on-chain. eg: rename FooBar -> Bar, not foo_bar_ to Bar if the name on-chain is foo_bar_

If no event is found, LatestRoundRequested should return zero values, not an error. An error should only be returned if an actual error occurred during execution, e.g. because there was an error querying the blockchain or the database.

As an optimization, this function may also return zero values, if no RoundRequested event has been emitted after the latest NewTransmission event.
