# Pay miner fee with tokens

When conducting any transaction on Ethereum, a certain amount of ETH is required as gas fees. This means when a wallet runs out of ETH, it becomes troublesome to proceed as you have to top up the wallet with more ETH from outside sources. This problem has been considered in our protocol design.

Our trade matching relayers are able to pay the ETH gas fees in advance on behalf of users, allowing them to complete their transaction even when they have no ETH in their wallets. If you need to make an ETH-less transaction, simply toggle the ‘Pay miner fee with tokens’ button in Tokenlon!

#### How to turn on the【Pay miner fee with tokens】mode

If you do not have ETH or enough ETH to pay the miner fee, we suggest you turn on the【Pay miner fee with tokens】mode. Please update your [imToken App](https://token.im/download) to v2.10.0 or above.

After finishing the update, please visit the【Market】page and click the gear button to enter the【Setting】page.

In the【Setting】page, click the button on the right to turn on the【Pay miner fee with tokens】mode.

As long as you turn on the【Pay miner fee with tokens】mode, you can make trades on Tokenlon even if you don’t have ETH to pay miner fees. The miner fee will be deducted from the tokens you receive.

#### Please note that

* If you turn on the【Pay miner fee with tokens】mode, the minimum trade amount will still be in effect.

#### Tips

* When the【Pay miner fee with tokens】mode is on, the transaction success rate on Tokenlon is over 99%. To prevent users from losing miner fees due to failed trades, we suggest you turn it on when the miner fee on the Ethereum network is relatively low and stable.
* When the【Pay miner fee with tokens】mode is on, the miner fee will no longer be displayed on the【Preview】page.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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://tokenlon.gitbook.io/docs/docs.en/blog/whatsnew/market-update/2023/0712.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.
