LTC Lottery NFT
Image lottery of LitVM. Mint your favorite image as an NFT ticket, winners drawn by verifiable randomness.
LTC Lottery NFT is a gaming application on LitVM that combines ERC-721 NFT minting with a weekly prize lottery. Described in the official directory as an image lottery powered by verifiable randomness, the platform allows participants to upload an image and mint an NFT that acts as a ticket for the current round. According to its site, the image is stored on IPFS, and the resulting NFT remains in the user's wallet as a collectible regardless of the outcome of the draw.
Questions
- How are lottery winners selected in LTC Lottery NFT?
- According to the project's documentation, winning tickets are chosen using verifiable randomness sourced from drand, a public randomness beacon run by the League of Entropy. An operator submits the drand value to the smart contract, where it is emitted on-chain so users can independently verify the result against public records.
- What happens to the NFT ticket after a round concludes?
- The ERC-721 NFT remains permanently in the minter's wallet as a collectible, displaying the round number and country of origin, whether the ticket won a prize or not.
- How are prize payouts distributed to winners?
- The project uses a pull-payment smart contract model where the contract logs owed prize amounts for three winning places per round. Winners can withdraw their funds independently at any time, allowing new lottery rounds to begin immediately without waiting for prize claims.
