There are many NFTs already deployed on the IoTeX mainnet such as the "Ucam Pioneer NFT" given to those who pre-ordered a Ucam before it was launched on Amazon, or the "Burn Drop Ignite" NFT, and more will be added in the future by upcoming dApps using trusted data from the real world like PebbleGo (see references below).

Build a general-purpose NFT marketplace with an eye on a modern UI providing a seamless user experience. It should include the following features:

User login with Metamask Allow a user to put an NFT on sale at a fixed price with title and description Allow a user to change the price of his NFTs while on sale List/Filter NFTs available for sale and display the actual content Allow website visitors to buy NFTs Allow website visitors to search NFTs by free text on title and description 25) brianspha has started work.

I would build a general-purpose NFT marketplace. 29) universenox has started work.

I will implement the marketplace as described, but only the basic features, as well as an auction (at least, initially), since I am not confident in my UI skills, and I'm unsure of the proper way to (safely) save/serve music/video/gif/arbitrary files. More details below.

Login will be done by having the user "personal sign" (https://geth.ethereum.org/docs/rpc/ns-personal#personal_sign) a unique message using their account, and the backend can verify the signature belongs to the given account (ecRecover), at which point we start a session using gorilla-sessions (which uses gorilla/securecookie). Https is required for security. We will also try using CSP for added security, but this may not play well with Metamask.

An important note on security: I do not have a trusted node to contact on the backend. Hence, I cannot verify what is truly on the blockchain. I am only able to verify that a user owns a given wallet. I will leave security up to each individual user and their Provider. Each user, presumably, can trust their own provider, and hence, each user can verify on their own (via the frontend web3) whether the information provided by other users matches what is on the blockchain. Postings with contradictory information will not be shown.

NFTs are not owned in the same way that ETH is. NFT ownership is recorded on the ERC721 contract, and not tied to the user's account; hence we cannot simply query the user's account for ownership. Instead, the user can provide the contract address (and relevant token id's, if the contract is non-enumerable, see: https://eips.ethereum.org/EIPS/eip-721#specification enumeration extension). An alternative could be to use some other API. The owned tokens will be saved. The user can then add additional metadata, including title, description, category, and image. The actual metadata URI that is stored on the blockchain may be shown as plaintext, but will not be accessed, due to security concerns.

A fixed price NFT sale contract and an auction contract will be written. They will be simple, and each contract will handle exactly one NFT sale. It is likely that a larger contract that handles many at once would save gas, but it would cause more trouble if something went awry, and harder to scan for vulnerabilities.

The search/display features should be straightforward.

First, I will get this working with an Ethereum testnet, and then I will try to get it working with an IoTeX testnet. I will use Go for the backend, React/MaterialUI for the front, and postgres for my database. Finally, I will host this and add some test account data, so that you may try it out.

when bounty get paid sir

Hey @deepface19 It seems your submission does not belong to our grant, or at least your NFT marketplace doesn’t seem to support IoTeX. Can you provide any link of a working demo for IoTeX?

deepface19 commented 3 years ago
