Hello @julio4 I'll like to be assigned to this

i can do this

@julio4 I'd like to take on the task of implementing and testing the ERC721 NFT contract. Here's my plan

What I'll Implement:

ERC721 Contract:
Mint new NFTs.
Transfer NFT ownership.
Query ownership and metadata.

Interface Methods:
Minting: Create new NFTs.
Transferring: Transfer ownership of NFTs.
Querying: Get ownership and metadata of NFTs.

Plan:
Implementation:

I will follow the ERC721 standard.
I will use minimal implementation for clarity.
I will refer to OZ ERC721 and our ERC20 for guidance.

Comprehensive Tests:

Test minting functionality.
Test transferring functionality.
Test querying ownership and metadata.
Cover edge cases like invalid transfers and minting.
I will also deploy the contract on a testnet to verify functionality.

Example Test Cases:
Minting:

Ensure new NFTs are created correctly.
Verify metadata is set correctly.

Transferring:

Ensure ownership is transferred correctly.
Handle invalid transfers.

Querying:

Verify correct ownership details.
Check metadata retrieval.

I think this should cover everything needed to make sure the NFT721 contract works correctly. Let me know if I can take this on. Thank you

Hello @julio4 I would like to be assigned to this. I am currently working on an ERC721 contract and I'm about to write tests for it. I can rewrite it to follow the pattern used for the ERC20 contract. I added an image to show what I am currently working on.

Thank you

Hi, @julio4,

I would like to help with this one if it hasn't been assigned yet. I have extensive experience with Solidity and smart contract development. Here’s my plan:

• Implement the ERC721 NFT contract focusing on minting, transferring, and querying ownership and metadata, leveraging OpenZeppelin's ERC721 for security and compliance.
• Write comprehensive tests to cover all interface methods, ensuring correctness and robustness.
• Deploy the contract on a testnet to validate functionality in a live environment and provide deployment instructions.
• I am confident I can complete this task within 4 days.

Thanks!

Hello @julio4 I'll like to be assigned to this

@raizo07 assigned for now

@raizo07 Any updates on this?

I am applying to this issue via OnlyDust platform.

My background and how it can be leveraged

I am a blockchain developer with experience in typescript, html, css, react, javascript cario and solidility . this would be my first time contributing to this ecosystem .. please i will love to be assigned to this issue

How I plan on tackling this issue

1. Implement Basic ERC721 Contract: Start by importing OpenZeppelin's ERC721 implementation as a base. Define the NFT's name, symbol, and any specific token properties. Implement core functions for minting, transferring, and querying ownership.
2. Interface Methods: Clearly explain each interface method and keep the implementation minimal while ensuring functionality is clear and concise.
3. Comprehensive Testing: Write unit tests covering minting, transfers, and ownership queries. Ensure edge cases like invalid transfers and approvals are handled.
4. Deployment on Testnet: After testing locally, deploy the contract to a testnet like Rinkeby or Goerli using Hardhat or Truffle. Verify deployment and functionality.
5. Use Existing ERC20 as Reference: Leverage your previous ERC20 implementation for contract structure, especially with testing and deployment scripts.

I am a Junior web developer, working with Javascript, HTML and CSS. I have over a decade experience designing graphics and organization branding.

How I plan on tackling this issue

I will follow the guidelines and put my creativeness to work

I am applying to this issue via OnlyDust platform.

My background and how it can be leveraged

I am a Web3 front-end developer skilled in technical documentation and software development. I greatly understand technologies like JavaScript, Typescript, Cairo, Rust and Solidity. I have contributed successfully to open-source projects like Stark Quest and Speedrun scaffold-stark.

How I plan on tackling this issue

My Approach includes :

• Thorough studying of the way ERC20 was implemented
• Follow the same procedure in the implementation of the ERC721.
• Create a Pull Request (PR).
• Request for a Review.
• Make changes based on the Review of the PR.
