# How to Pay Gas in ERC-20 Tokens | EIP-7702

**Smart EOAs via EIP-7702**

Enable users to pay gas in ERC-20 tokens using any [supported ERC-20 token](https://docs.candide.dev/wallet/paymaster/tokens-supported.md) on Candide Paymaster.

1. Create a new app on the [dashboard](https://dashboard.candide.dev) and copy the Paymaster URL to your `.env` file
2. Select an ERC-20 token for gas payment and add its address to the `.env` file (this example uses CTT)

If you would like to see a full example, you can reference it [here](https://github.com/candidelabs/abstractionkit-examples/blob/main/eip-7702/simple-account/02-upgrade-eoa-erc20-gas.ts).

* index.ts
* .env

```
import {

  ...

  Erc7677Paymaster,

} from "abstractionkit";



const paymasterRPC = process.env.PAYMASTER_RPC as string;

const tokenAddress = process.env.TOKEN_ADDRESS as string;



const paymaster = new Erc7677Paymaster(paymasterRPC)



const { userOperation: tokenOp, tokenQuote } = await paymaster.createPaymasterUserOperation(

    smartAccount, // = new Simple7702AccountV09(eoaDelegator.address)

    userOperation,

    bundlerUrl,

    { token: tokenAddress },

)

userOperation = tokenOp;

const cost = tokenQuote?.tokenCost;

console.log("This useroperation may cost up to : " + cost + " in the token")

console.log("Please fund the sender account: " + userOperation.sender + " with at least " + cost + " of the token")
```

info

Don't forget to fund the account with ERC-20s to pay for gas. We are using Candide Test Tokens (CTT) for this example. Get test tokens from our [dashboard faucet](https://dashboard.candide.dev/faucet) - supporting CTT and USDT on testnet.
