+## Appendix A: Example Implementation
+
+Do note that the implementations below are the current implementations, and may change in the future.
+
+### Viem Example
+
+```typescript
+import { getEnsAddress } from "viem/actions";
+import { mainnet, optimism } from "viem/chains";
+import { createPublicClient, http } from "viem";
+import { evmChainIdToCoinType } from '@ensdomains/address-encoder/utils';
+
+const client = createPublicClient({ transport: http(), chain: mainnet })
+
+const name = "luc.eth";
+const targetChain = optimism;
+
+// First lookup the targetChain address
+const target_address = await getEnsAddress(client, { name, coinType: evmChainIdToCoinType(targetChain.id) });
+
+// Then lookup the EOA address if needed
+const address = target_address || await getEnsAddress(client, { name, coinType: evmChainIdToCoinType(0) });
+```
+
+### Wagmi Example
+
+```typescript
+import { useEnsAddress } from "wagmi";
+
+const { data: resolvedAddress } = useEnsAddress({
+  name,
+  coinType: evmChainIdToCoinType(chain.id)
+});
+
+const { data: fallbackAddress } = useEnsAddress({
+  name,
+  coinType: evmChainIdToCoinType(0),
+  enabled: !resolvedAddress
+});
+
+const address = resolvedAddress || fallbackAddress;
+```
