The problem Total Recall - EIP: Recallable Token Standard solves

A significant challenge persists: once real-world assets (RWAs) like real estate or art are tokenized and distributed among investors, the original owner loses the ability to manage or sell the asset as a whole. This limitation hinders the practicality and appeal of RWA tokenization.

Our project, "Recallable Real-World Asset Tokens," offers a groundbreaking solution. We enable RWA owners to tokenize assets and maintain the right to recall all issued tokens, providing much-needed flexibility. This approach is particularly advantageous in scenarios where the asset needs to be sold as a whole or if the owner’s plans change.

Our project, Total Recall, directly addresses the current limitations in Real World Asset (RWA) Tokenization by offering:
- Ownership Fluidity: Enables asset owners to tokenize and sell their assets, while maintaining the right to later recall the tokens and regain full ownership.
- Improved Asset Liquidity: Through tokenization, assets are broken into smaller units, making investments more attainable and markets more liquid.
- Investor Profit Guarantee: The recall price can be set higher than the initial offering, assuring investors a guaranteed profit margin.
- Real Estate: Real estate owners can tokenize their properties, sell to various investors, and later recall the tokens to sell the property in its entirety.
- Art Market: Art owners can tokenize their pieces, sell fractional ownership, and still retain the ability to recall for complete sale or exhibitions.
- Crowdfunding: Startups can issue recallable tokens to raise funds and later offer an exit strategy to investors by recalling them upon scaling up.

We created & submitted EIP to standardize RWA tokenization.

Challenges we ran into

During development, we encountered several hurdles, particularly in integrating various blockchain technologies to create a seamless, user-friendly experience. One significant challenge was ensuring the robustness and security of the smart contract handling the recall function. Ensuring that the recall process was fair, transparent, and tamper-proof required meticulous coding and rigorous testing.
Another challenge was integrating external APIs like 1inch Swap and XMTP for a fluid transaction and communication process. We faced initial difficulties in ensuring smooth data transfer and user experience, which we overcame through iterative testing and optimizing our codebase.
Perhaps the most daunting challenge was implementing the 'Anon Aadhaar' KYC process while respecting user privacy and complying with regulatory standards. This required a delicate balance between functionality and security, which we achieved through collaborative problem-solving and consultation with blockchain security experts.
These challenges not only tested our technical capabilities but also provided valuable learning opportunities. Overcoming them has not only improved our project but also enhanced our skills as developers and innovators in the blockchain space.
