Hi all, I am a web3 developer and I am looking to launch an NFT platform app on the App Store with marketplace features. The platform will allow users to connect their external web3 wallets (like Metamask, Coinbase, etc.) and purchase and sell NFTs on the marketplace in the app. All the purchases will be made through the Ethereum (ETH) cryptocurrency existing within the external wallet, hence the transactions will be registered on the ETH blockchain network. The platform will not provide features to buy cryptocurrencies like ETH from the open market. I need help to get confirmation if the In-App Purchase is required for my app? Will the In-App-Purchase charges be applicable to such purchases through the external wallets? Will my app be allowed during App review? Thanks!
