description: Reverse ENS lookup — turn a 0x address into a human-readable name like `vitalik.eth`. Cheap, single API call. Use whenever you have an address and want to display a friendlier identifier alongside it.

# vike-wallet-ens

## Command

```bash
vike wallet ens <address> [--json]
```

## Example

```bash
vike wallet ens 0xd8da6bf26964af9d7eed9e03e53415d37aa96045
# → { "address": "0xd8da...", "ens": "vitalik.eth" }

vike wallet ens 0x28c6c06298d514db089934071355e5743bf21d60
# → { "address": "0x28c6...", "ens": null }      (most exchange wallets have no ENS)
```

## When to use

- Right after any tool returns a wallet address — show ENS as a secondary label
- When the user pastes an address and asks "who is this"
- When you're about to display a leaderboard with addresses — enrich each row with ENS if available

## Anti-patterns

- Don't replace the address with the ENS name in tool output — show BOTH. The address is canonical; ENS is a display layer that can change ownership.
- Don't ENS-lookup hundreds of addresses in a leaderboard at once — credits add up. Usually ENS-lookup only the top 5-10 rows the user is likely to act on.
- A `null` response is normal, not an error. Most wallets don't have ENS.

## Pairs well with

- `vike labels <addr>` — combine ENS + labels for the fullest identity view
- `vike wallet summary <addr>` — ENS + activity profile
- `vike funds` — pair with ENS lookups on the top entries for richer display
