getOperatorDelegatorsHistory

Usage

import { getOperatorDelegatorsHistory } from "common-crypto-tools/eigenlayer";

const provider = new ethers.providers.JsonRpcProvider(
  "https://eth-mainnet.g.alchemy.com/v2/YOUR_API_KEY"
);

const data = await getOperatorDelegatorsHistory(provider, {
  fromBlock: 19576120,
  operator: "OPERATOR_CONTRACT",
}); // 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
}

Return value

// key is delegator address
Map<string, OperatorReStakerAction>

type OperatorReStakerAction = {
  amount: BigNumber;
  block: BigNumber;
  action:
    | typeof OperatorSharesDecreasedAction
    | typeof OperatorSharesIncreasedAction;
};

Examples

import { getOperatorDelegatorsHistory } from "common-crypto-tools/eigenlayer";
