# 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.
