BTH key mechanics.

Technical solution

  • We have created a separate smart contract for each type of key.

  • Chosen network - Polygon, token standard ERC-721.

  • We use DAO voting mechanics.

  • We mint BTH (user keys/cards) from each smart contract.

  • Cross-chain support for 18 blockchains.

  • We use Metamask wallet for authorization, and upon authorization, we check the wallet ID. If the wallet owns BTH, then access is granted with the corresponding level.

  • The "Learn-and-Earn" reward mechanism.

  • Developed web-3 custom node cross-chain protocol, NFT authentication service on Polygon.
