Supply limits and blacklist check

Each pricing tier has a fixed supply. When a tier sells out, it automatically advances to the next tier. Current supply availability is shown on the purchase page. If your wallet is on the Autheo blacklist, the purchase button will be disabled. Contact Autheo support if you believe this is in error.

​
After your purchase

On the Success page (/success), you will see a transaction summary and a link to return to the Purchase page. Your new license NFT will appear in your wallet. Your next step is to import the NFT into MetaMask for visibility and then bridge it to Autheo Chain. See Order history and NFT import for the import steps.
