# Pay gas with ERC-20

> Let your users pas for gas with ERC-20 tokens

You can choose what asset to use as a fee token (i.e., to cover gas and bridging fees):

```ts {10} theme={null}
const transaction = await rhinestoneAccount.sendTransaction({
  sourceChains: [base],
  targetChain: arbitrum,
  calls: [
    // …
  ],
  tokenRequests: [
    // …
  ],
  feeAsset: 'USDC',
})
```
