Corporate actions on Arbitrum

This guide walks you through consuming Kaiko’s Corporate Actions data on Arbitrum. Kaiko publishes corporate action events (dividends, splits, mergers, …) for a sample universe of US equities: one feed contract per equity, holding the latest Kaiko-signed payload. Signatures are verified on-chain (EIP-712), so consumers only need to trust Kaiko’s signer — not whoever submitted the transaction.

Read the feed on-chain

Each equity has its own CorporateActionsFeed contract exposing getItems(), which returns the equity’s identifiers and its corporate action events (action type, status, ex-date, dividend details, …).

This TypeScript example reads Apple’s feed with ethers:

import { ethers } from 'ethers';

const provider = new ethers.JsonRpcProvider("<YOUR_PROVIDER_URL>");

const abi = [
  "function getGeneratedAt() view returns (string)",
  "function getItems() view returns (tuple(tuple(string isin, string ticker, string issuerName, string exchangeMic, string bbgCompId, string bbgCompTicker, string figi, string figiTicker, string timezone) idDetails, bool isTruncated, tuple(string eventUniqueId, string eventId, string ediEventCode, string actionType, string status, string eventCreatedAt, tuple(string actionType, string exDate, string recordDate, string paymentDate, string currency, string grossDividend, string dividendType) caDetails, string lastUpdatedAt)[] events)[])"
];

// AAPL feed
const feed = new ethers.Contract("0xD2Ee465ee2263FaB0F7cc97fAC300A5C66c2b9DA", abi, provider);

async function readCorporateActions() {
  const [generatedAt, items] = await Promise.all([
    feed.getGeneratedAt(),
    feed.getItems(),
  ]);

  console.log("Payload generated at:", generatedAt);
  for (const event of items[0].events) {
    console.log(
      event.actionType,
      "| status:", event.status,
      "| ex-date:", event.caDetails.exDate,
      "| dividend:", event.caDetails.grossDividend, event.caDetails.currency
    );
  }
}

readCorporateActions().catch(console.error);

All fields are strings; dates are RFC3339 UTC and an empty string means the value is not available. To consume the feed from another smart contract, declare the same structs as the feed contract and call getItems() through an interface.

{% hint style=“warning” %} Each update replaces the stored events: a feed holds only the latest verified payload, and each equity’s feed must be read individually. Past payloads remain available through the PayloadPublished event log. {% endhint %}
