# Example ERC20 token API

This example shows how to create a GraphQL API for an ERC20 token using Ponder. It uses the Adventure Gold token contract on Ethereum ([Link](https://etherscan.io/address/0x32353A6C91143bfd6C7d363B546e62a9A2489A20)).

## Sample queries

### Get the current balance and all approvals for an account

    balance
    approvals {
      spender
      amount

```graphql
{

```

### Get the current owner of the token contract

```graphql

  accounts(where: { isOwner: true }) {
    id

}
```

### Get all transfer events for an account

```graphql

  account(id: "0x1337f7970E8399ccbc625647FCE58a9dADA5aA66") {
    transferEventsTo {
      from
      amount
    }
    transferEventsFrom {
      to
      amount
    }
  }
}
```
