## Signing

{% hint style="info" %}
See more details and examples in our [signing](https://docs.nado.xyz/developer-resources/api/gateway/signing) page.
{% endhint %}

The solidity typed data struct that needs to be signed is:

```solidity
struct MintNlp {
    bytes32 sender;
    uint128 quoteAmount;
    uint64 nonce;
}
```

<mark style="color:red;">`sender`</mark>: a <mark style="color:red;">`bytes32`</mark> sent as a hex string; includes the address and the subaccount identifier.

<mark style="color:red;">`quoteAmount`</mark>: this is the amount of quote to be consumed by minting NLPs, sent as a string. This must be positive and must be specified with 18 decimals.

<mark style="color:red;">`nonce`</mark>: the <mark style="color:red;">`tx_nonce`</mark>. This is an incrementing nonce, can be obtained using the [Nonces](https://docs.nado.xyz/developer-resources/api/gateway/queries/nonces) query.

{% hint style="warning" %}
**Note**: for signing you should always use the data type specified in the solidity struct which might be different from the type sent in the request e.g: <mark style="color:red;">`nonce`</mark> should be an <mark style="color:red;">`uint64`</mark> for **Signing** but should be sent as a <mark style="color:red;">`string`</mark> in the final payload.
