NFT Lottery on Solana
The user has to first submit SOL worth $1 at that current moment, which is checked against the live price feeds of SOL/USD being fetched by pyth-network/Chainlink. Winners will charge 65%, a major part of the rest will be distributed as charity. Depending on the matched number count, we again split 65% to each winner. 3 match: they will get the ticket price back. 4 matched: these users will receive 2% / N of the total lottery amount. 5 matched: these users will receive 5% / N of the total lottery amount. The final winners who matched all numbers will have the rest 65% - low tier prizes. All "low tier" prizes are subtracted from the main prize pool of 65%. Thus, if no low tier winners, then they will get a full 65%.
The Randomisation of the winning lottery numbers is done with the help of VRFs from Chainlink itself.
