We want to raffle away a single NFT (token) based off of another NFT collection (or drawingToken) in a fair and trustless manner.
체인링크를 활용해서 NFT 라플을 돌리는 프로젝트. 유저들이 NFT를 넣어서 래플을 돌리고 당첨자에게 새로운 NFT를 클레임할 수 있도록 하는 것이 전체적인 흐름이다.

후기
LOC가 너무 짧아서 그런지 결함은 못 찾았다. 내가 발견하지 못 한 걸 수도 있으니 나중에 레포트 나오면 꼭 다시 봐야겠다. 기간이 겹치는 콘테스트가 많이 있을 경우 LOC가 너무 짧은 것들은 후순위로 두는 것이 나을 것 같다.
Just BUIDL :)
