2.2 The Certification Token (SBT)

Soulbound and Non-Transferable

Reticula Tokens adhere to an extended ERC-721/SPL standard that enforces non-transferability, meaning the transfer() function is disabled. This is crucial for maintaining the integrity of the purchase proof.

Key On-Chain Metadata Fields:

Field Name	Type	Description
cert_type_id	UINT	Unique ID representing the type of service purchased (e.g., 0x01 for Data Feed, 0x02 for API Access).
target_hash	BYTES32	Cryptographic hash of the target service endpoint (or dataset).
original_tx_hash	HASH	Hash of the original successful X402 payment transaction.
expiry_timestamp	TIMESTAMP	UNIX timestamp when the access right expires.
value_paid	UINT	The exact amount of X402 currency paid for reference.

Importance: The non-transferable nature prevents agents from selling, renting, or sharing their valid access rights, directly protecting the Service Provider's revenue.
