+The SDK automatically manages multiple instances based on chainId. When using hooks or utilities, just specify the chainId to use the corresponding instance:
+
+```ts
+// Will use Ethereum mainnet instance
+const ethPool = await getPool({ tokens: [...] }, 1);
+
+// Will use Base instance
+const basePool = await getPool({ tokens: [...] }, 8453);
+
+// If you only have one instance, chainId is optional
+const singleChainPool = await getPool({ tokens: [...] });
