MATIC (and ETH) are not ERC20 tokens, they are native tokens. Before we proceed we need to know the difference between native and ERC20 tokens. The following article can prove to be useful: . In the background, when using MATIC/ETH for blockchain operations, they are wrapped (converted to ERC20 token) and afterwards used for the operation itself. In that regards, Kromatika's GASless contract cannot operate with native tokens, it only accepts ERC20 tokens. Note: this only applies when you trade MATIC to anything else; {% embed url="" %}

Figure A

**Figure A** shows that the "From" sender is not the actual address, because it is executed by Biconomy. Notice that there is also transaction fee existing. GASless does not mean feeless. Blockchain fees still exist and cannot be avoided, but they are being paid by Biconomy. For that service they charge same amount as the transaction fee denominated in output token. The last transaction of 1.19 KROM is for the relayer. The above transfer of 13.04 KROM is what the user actually gets The other transfers are regular swap transfers that occur as in regular aggregate swap. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.kromatika.finance/kromatika-dapp-2.0/tutorials/how-to-use-gasless/what-does-switch-to-wmatic-or-wrap-your-matic-mean.md?ask=&goal= ``` `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.
