# transferERC20

Transfer L2 ERC-20 tokens from one user to another.

## Usage

The following example is an advance handler that transfers 1 CTSI from the sender of the input to a recipient specified in the input payload.
If the sender does not have enough balance an exception is raised, and that handler is aborted.

```ts twoslash
import { Rollup, chain } from "@cartesi/rollup";
import { createWallet } from "@deroll/wallet";
import { parseUnits } from "viem";

// open the rollup device
const rollup = new Rollup();

// create wallet
const wallet = createWallet();

const token = "0x491604c0FDF08347Dd1fa4Ee062a822A5DD06B5D"; // CTSI address
rollup.run({
    advance: chain(wallet.handler, ({ msgSender, payload }) => {
        const value = parseUnits("1", 18);
        const address = payload.toString();
        wallet.transferERC20(token, msgSender, address, value); // [!code focus]
        return true;
    }),
});
