Dynamic Address Lookups

Looking up vault addresses

You can query vault addresses dynamically using the BookManager:

import { publicClient, BOOK_MANAGER } from './config';

// Get vault for any currency
const vaultAddress = await publicClient.readContract({
  address: BOOK_MANAGER,
  abi: bookManagerAbi,
  functionName: 'getVault',
  args: [currencyAddress], // Currency as address
});

BookIds

BookIds are deterministically computed from a BookKey. Use the subgraph or BookManager to query active books:

// Query BookId from BookManager
const bookId = await publicClient.readContract({
  address: BOOK_MANAGER,
  abi: bookManagerAbi,
  functionName: 'getBookId',
  args: [bookKey],
});

See Query subgraph for how to fetch books and their IDs via GraphQL.
