+## Arweave Name Tokens (ANT's)
+
+The ANT contract client class exposes APIs relevant to compliant Arweave Name Token contracts. It can be configured to use any contract ID that adheres to the ANT contract spec. You must provide either a custom contract data provider or a contractTxId to the ANT class constructor to use.
+### `getRecords({ evaluationOptions })`
+
+Returns all records on the configured ANT contract, including the required `@` record that resolve connected ArNS names.
+
+```typescript
+const contractTxId = 'bh9l1cy0aksiL_x9M359faGzM_yjralacHIUo8_nQXM';
+const ant = new ANT({ contractTxId });
+const records = await ANT.getRecords();
