# Swap Architecture

At the core of Gamerse’s ecosystem is the ability to securely swap cryptographic tokens in a decentralized way. It does this through the use of an escrow smart contract to hold both NFT and ERC-20 tokens until the correct conditions have been met for release.

$LFG can be used in place of ETH as payment for NFTs. Both buyer and seller fees receive a 50% discount on fees when $LFG is utilized as the base currency in the transaction.

Gamerse also supports other ERC-20 currencies and charges a 0.50% fee to swap.

## 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://gamerse.gitbook.io/gamerse/tokenomics/swap-architecture.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.
