# Native Token Address

> The sentinel address used for the native token.

Skip approval for the native token (e.g. ETH). Use this address for comparisons:

```text theme={null}
0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE
```

Filter it out before calling `getAllowance` or `approve`:

```typescript theme={null}
const NATIVE = "0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE";
const tokensForApproval = tokens.filter(
  (t) => t.address.toLowerCase() !== NATIVE.toLowerCase()
);
```
