A simple smart contract that mints a non-fungible token (NFT, but a very simplified version) or a standard ERC-20 token with a supply of "1" to an address that provides a specific "secret code" provided at the event.
Blockchain-based attendance verification using a secret event code and one-per-wallet on-chain claims.
Problem Statement: Event organizers need a simple, immutable way to verify and reward attendance at a specific physical or virtual event.
● Proposed Solution: A simple smart contract that mints a non-fungible token (NFT, but a very simplified version) or a standard ERC-20 token with a supply of "1" to an address that provides a specific "secret code" provided at the event.
● Core Smart Contract Logic:
○ A state variable for a secret code/password.
○ A function claimAttendance(string memory secret) that verifies the code.
○ If correct, call a minimal_mint function (or just record the address in a mapping). Focus on the logic, not complex NFT standards.
