Schema UID:

This value is used to declare the EAS schema UID for this attestation. It is automatically calculated.

Reference UID: This value is used to link the attestation to another EAS attestation. The field is optional.

TokenScript / Token Negotiator

Magic Link Base URL: The URL defines where the user gets directed to when clicking on the Magic Link. This is usually the URL of the TokenNegotiator outlet site where the attestation will be saved in local storage.

TokenScript URL: The URL defines the location of a TokenScript that can be used with this attestation.

Step 2 - Generate Attestations & MagicLinks

Create Attestation

Attestor Private Key Hex

The private key is used to compute a digital signature that may be verified by the corresponding public key. You can generate an ethereum private key securely by running the following command in a linux/unix shell:

head -c 32 /dev/urandom|xxd -ps -c 32

Please ensure you write down your private key and store it somewhere safe.

Recipient Address: This address is used to issue the attestation to a specific ethereum address. The field is optional

Field	Value	Static

Click on Generate to create a single attestation and MagicLink with the values entered above.
To create attestations in bulk, you can download the CSV template, fill it with rows and upload it here using the bulk generate button. Or you can use an existing CSV and map the source columns to each schema field. Ticking the "static" checkbox omits the field from the import and instead uses the value defined above for all attestations. Attestations will be generated and saved in a CSV download.
