[Experimental] [POC] ERC-5643 Subscription NFTs

0xandee commented 2 days ago

Create and work inside folder experimental/erc_5643_subscription_nft:

It proposes an additional interface for NFTs to be used as recurring, expirable subscriptions. The interface includes functions to renew and cancel the subscription.

Implementation Details:

The design and approach are left to the discretion of the assignee.
NFTs are commonly used as accounts on decentralized apps or membership passes to communities, events, and more. However, it is currently rare to see NFTs like these that have a finite expiration date. The "permanence" of the blockchain often leads to memberships that have no expiration dates and thus no required recurring payments. However, for many real-world applications, a paid subscription is needed to keep an account or membership valid.

Mid level Cairo Developer

How I plan on tackling this issue

I will implement a contract that supports NFT subscriptions with expiration dates, then include functions to renew, cancel, and check the expiration status.

My background and how it can be leveraged

I am shantel peters, a frontend and blockchain developer , with experience in cairo, html, css, react , solidity, javascript, typescript etc. My experience with blockchain and smart contract development positions me well to design this system and create an intuitive frontend for managing subscription statuses and payments. kindly assign

How I plan on tackling this issue

To solve the issue of implementing ERC-5643 subscription NFTs, I would design a smart contract that allows NFTs to act as recurring, expirable subscriptions. The contract would include functions for renewing and canceling the subscription, enforcing an expiration date and recurring payments for continued access. By following the ERC-5643 standard, I would ensure compatibility with existing NFT ecosystems while providing flexibility for real-world applications like memberships and subscriptions.

My background and how it can be leveraged

I have contributed to several Cairo projects on OnlyDust and I've worked on very similar issues in the past, porting Solidity ERCs to Cairo eg. https://github.com/carbonable-labs/cairo-erc-7496 and https://github.com/carbonable-labs/cairo-erc-7498

How I plan on tackling this issue

I will carefully read the ERC and proposed Solidity implementation and I'll implement the expected behavior in Cairo. I will then use Starknet Foundry to test if the implementation is correct.

My background and how it can be leveraged

I started with cairo a month ago and have been actively solving algorithm problems to build my problem-solving skills in the language and has also helped me develop a strong understanding of cairo’s capabilities. I also prioritize the time complexity and efficiency of my solutions ensuring optimal performance. I am now looking forward to garnering more experience by contributing to actual projects.

How I plan on tackling this issue

Assuming there's an NFT struct available, my approach would be to create a trait which provides the renewal and cancel actions. The renewal function would call the payment processing method and update the renewal date while the cancel function would restrict user's access to the NFT effectively ending the subscription.
