Smart Contract

Solidity code can be found at contracts/ folder.

Currently hosted on Goerli.

Available methods:

• safeMint(string uri, uint256 ethPrice, uint256 usdcPrice): mint token with the specified IPFS uri (link part after https://ipfs.io/ipfs/) and prices in ETH and USDC
• buyEth(uint256 tokenId): buy specified token in ETH (price can be seen by invoking tokenPriceEth(uint256 tokenId))
• buyUSDC(uint256 tokenId): buy specified token in USDC (price can be seen by invoking tokenPriceUSDC(uint256 tokenId)). Before invoking this method, this contract should be approved to transfer USDC from your account

After any successful deal, the price is increased by a constant amount.
