Examples
The following are full examples of EIP12 typed data for each of Nado's executes. Each execute includes a sender field which is a solidity bytes32 . There are two components to this field:
- an
addressthat is abytes20 - a subaccount identifier that is a
bytes12
For example, if your address was 0x7a5ec2748e9065794491a8d29dcf3f9edb8d7c43, and you wanted to use the default subaccount identifier (i.e: an empty identifier "") you can set sender to 0x7a5ec2748e9065794491a8d29dcf3f9edb8d7c43000000000000000000000000 , which sets all bytes of the subaccount identifier to 0.
{% hint style="info" %}
Note: a bytes32 representation of the sender must used when signing the request.

See below a sample util to convert a hex to a bytes32:
