}); // Map<string, Map<string, OperatorReStakerAction[]>>

Params

• provider: ethers.providers.JsonRpcProvider
• options: Options

Options

type Options = {
  fromBlock?: number;
  toBlock?: number;
  operator: string;
  delegationContract?: string; // By default it's EigenLayerDelegationContract: 0x39053D51B77DC0d36036Fc1fCc8Cb819df8Ef37A
