# Trading wallet selection

Token Detail lets you choose how the wallet for the current Buy or Sell action is sourced.

## Where to choose

Open a Token Detail page and use the **Trading Wallet** selector in the trading area. Before review, it shows the wallet source, current network, and shortened public address.

## In-product wallet

To use a KK.one Wallet Group:

1. sign in to KK.one;
2. choose **In-product wallet** or the equivalent option;
3. select a compatible Wallet Group such as W1 or W2;
4. confirm that the selected network and balance match the token;
5. continue to trade review.

If you are signed out, KK.one asks you to sign in before offering an in-product Wallet Group.

## External wallet

To use an external wallet:

1. choose **External wallet**;
2. connect a supported wallet;
3. approve the requested connection or transaction in that wallet;
4. confirm the wallet's network and public address in KK.one;
5. continue to trade review.

KK.one should never ask you to paste an external wallet private key or seed phrase.

## What switching changes

Switching the Trading Wallet changes the funding and signing source for the current trade. It does not:

* sign you out of KK.one;
* change which account is verified as the token creator;
* transfer creator rights;
* change the network-specific destination assigned to Creator Rewards;
* change an already submitted transaction.

## Trade review lock

One trade review is bound to one wallet source, network, address, token contract, quote, amount, slippage setting, and fee estimate. If any of these changes, the review is refreshed before submission.

## Common mismatches

* Wallet connected to the wrong network.
* Insufficient native asset for the network fee.
* Insufficient token balance.
* Quote expired before authorization.
* Token contract does not match the selected network.
* Trading is unavailable even though public Token Detail data remains visible.

Trading availability and estimates do not guarantee execution, price, liquidity, or profit.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://kkone.gitbook.io/kkone-docs/wallets-and-trading/trading-wallet-selection.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
