# Gas Credit

One of the major obstacles faced by Web3 users is the incompatibility between different chains. Experienced Web3 users are familiar with keeping certain native tokens such as ETH, OKB for gas fee purposes. However, this can be confusing and inconvenient for inexperienced Web3 and Web2 users. 

The Gas Account solves this problem with the paymaster function in account abstraction (ERC-4337). As a result, OpenSocial users can top-up gas credit from any of the supporting EVM chains and not need to concern themselves with acquiring native tokens for their corresponding social assets.  The paymaster function also enables third parties, such as any web3 dApp or OpenSocial as the underlying protocol to pay gas fees on users’ behalf.

**Supported EVM chains**

## 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://gitbook.opensocial.co/features/opensocial-account/gas-credit.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.
