Description

In this example, we will show the implementation of an NFT minting contract using a Dutch Auction, where the minting price follows a decreasing price curve.

Minting Details

The seller of the NFT deploys this contract with a startingPrice.
The auction lasts for a specified duration.
The price decreases over time.
Participants can purchase NFTs at any time as long as the totalSupply has not been reached.
The auction ends when either the totalSupply is reached or the duration has elapsed.

Criteria:

Price is denominated in IERC20 priceToken
Include comprehensive tests
Deploy the contract on a testnet

Hi @julio4, I'm a returning contributor from previous ODHacks (check my OD profile here) and I'd love to handle this issue.

In particular, I have experience porting Solidity code to Cairo as I did in Solidity EIPs to Cairo conversions such as ERC7496 and ERC7498. I will study the Solidity by Example code and carefully replicate it using Cairo and OpenZeppelin ERC20/ERC721 implementations. I will replace the Solidity price logic using msg.value with proper Starknet logic using an ERC20 as price token and transfer_from method. I will include starknet-foundry to write comprehensive tests making sure we have 100% coverage for this example and deploy on Starknet Sepolia.

Hello everyone! I assigned @princeibs for this time!

@princeibs Are you still working on this? @julio4 Following up on my TimeLock implementation in #201 I'd like to continue working on StarknetByExample and handle this issue (please refer to my previous comment).

Yeah sure. Almost done. Will be creating a PR asap.
