05 / PRINCIPLES
COSIGN separates current ownership from historical origin. Tokens can circulate freely while the fact that they were created together remains permanent.
A wallet address entered into a form is not completion. The designated Wallet B must submit its own payment before the contract mints anything.
Neither the website owner nor Wallet A can manufacture Wallet B's transaction.
The A and B tokens are not locked together after mint. Their owners can transfer or list them independently like other ERC-721 assets.
A later buyer receives the token and its verifiable history, not control over the paired token.
Both tokens permanently reference the same pair ID. Changing owners does not delete, replace, or recreate that relationship.
The chain preserves which two tokens began from the same completed invitation.
The public interface makes COSIGN easier to use, but the deployed contract remains the source of truth for payments, token ownership, refunds, and pairing data.
Verified source code allows participants and marketplaces to inspect those rules independently.
