ERC1155 Lottery Tickets

EvolveArt commented 2 years ago

First complete draft of Lottery Tickets implementation as ERC1155 tokens.

ERC1155 standard taken from here and improved.

Some improvements are still to be made :

[ ] Adapt to OZ standards when adopted (soon?)
[x] Complete _balance_to_tickets method (tier system vs formula)
[x] Implement batchClaimLotteryTickets to claim tickets for multiple IDOs at once
[x] Explore order-book design for easy trading on-chain
[ ] Gas Optimizations (if needed)

Some questions still to be answered:

Should VRF be added in IDO contract or this one?

For on-chain trading, looks like we could take inspiration from realms-contracts

One thing to mention here. The standard in cairo is to name the contract where the logic is library.cairo ERC1155_base.cairo -> library.cairo Example
