# Chat & Address Detection

> How the chat interface works, and how Nikiwa detects blockchain addresses in your messages.

## The chat interface

Nikiwa is conversational. Every answer is grounded in tool results, so you can follow up ("now show me its top counterparties") and Nikiwa keeps the context. The wallet, token, or transaction you were discussing carries forward.

Each response combines three things:

## Address detection

As you type, Nikiwa detects blockchain addresses and transaction hashes in your messages and makes them actionable. Hover to copy, or save to your [address book](/product/address-book).

<Info>
  Detection runs on your messages only, never on Nikiwa's responses.

Nikiwa recognizes address and hash formats across its supported networks.

| Network        | Address format                       | Transaction hash                   |
| -------------- | ------------------------------------ | ---------------------------------- |
| Ethereum / EVM | `0x` followed by 40 hex characters   | `0x` followed by 64 hex characters |
| Bitcoin        | Legacy (`1`, `3`) and SegWit (`bc1`) | 64 hex characters                  |
| Tron           | `T` followed by 33 characters        | 64 hex characters                  |
| Solana         | Base58, 32 to 44 characters          | Base58, 87 to 88 characters        |

When a detected address is already in your address book, Nikiwa shows its saved label so you recognize it immediately.

## Resolving symbols and names

You do not always need a raw address. Nikiwa resolves token symbols to contract addresses, and ENS names to Ethereum addresses. If a symbol is ambiguous across chains, include the network to disambiguate.
