v0.2.0 - Rewards v2.1 testnet

Notable changes

• Added functions related to the rewards v2.1 release:

  • ChainReader.GetOperatorSetSplit in chainio/clients/elcontracts

    operatorSplit, err = chainReader.GetOperatorSetSplit(
        context.Background(),
        operatorAddr,
        operatorSet,
    )

  • ChainWriter.SetOperatorSetSplit in chainio/clients/elcontracts

    receipt, err = chainWriter.SetOperatorSetSplit(
        context.Background(),
        operatorAddr,
        operatorSet,
        split,
        waitForReceipt,
    )

• Removed deprecated functions:

  • NewAVSRegistryContractBindings: use avsregistry.NewBindingsFromConfig instead
  • BuildAvsRegistryChainReader: use avsregistry.NewReaderFromConfig instead
  • BuildAvsRegistryChainSubscriber: use avsregistry.NewSubscriberFromConfig instead
  • BuildAvsRegistryChainWriter: use avsregistry.NewWriterFromConfig instead
  • NewEigenlayerContractBindings: use elcontracts.NewBindingsFromConfig instead
  • BuildELChainReader: use elcontracts.NewReaderFromConfig instead

• Removed RegisterOperatorInQuorumWithAVSRegistryCoordinator from avsregistry.ChainWriter.

  • Users should use RegisterOperator or interact with bindings directly.

• Removed panics from some functions. BuildReadClients, BuildAll, NewZapLoggerByConfig, and AvsRegistryServiceChainCaller.GetOperatorsAvsStateAtBlock return errors instead of panicking. The OperatorsInfoServiceInMemory no longer panics (errors are only logged).

• Added documentation to all functions in chainio/clients/elcontracts and chainio/clients/avsregistry.

• Added some functions related to slashing. More incoming in a future release.
