What inspired the idea forDelegated Accounts and Crypto Plastic Money, and how does it aim to solve the security and usability challenges in crypto?

[kishan1729]

Hello welcome to hackathon S7! This concept is impressive, especially the idea of combining NFC and crypto to create a plastic-like card. It’s great that users can set up limits and track delegate transactions. A small suggestion—focusing more on simplifying the user interface will help bring this idea to a wider audience. Excited to see how this evolves!

Hey @ankitmawle , Can you explain more about how the admin contract works in situations where the main account holder is unavailable? Are there plans for emergency protocols?

[ankitmawle]

Actually we are working a better and more simplified UI, but are a bit behind schedule due to other development related to IC, hope you will like the new UI once we release it, will let you know once we have it deployed

[ankitmawle]

Admin contract has method that allows the the admin account( which as of now I am holding), to disable any delegate card. For security and transparency, the admin account can only restrict(or block) a delegate card, but could never send any other transaction.

we are planning to integrate with some social login based system to connect your account, to send stoppage request to admin account. We are yet to decide on the actual social login to use and are open to suggestions

[kishan1729]

No worries! I understand how it goes with balancing different tasks. I’m looking forward to seeing the new UI when it’s ready. Keep up the great work, and definitely let me know when it’s live!

Inspiration and Project Goal

Why isn’t Crypto as mainstream as Centralized monetary systems?
What are some major factors making people avoid using crypto for usual monetary transactions?

• One such factor is the sense of security, One might feel safe with their money when it is locked some where safe, when you are confident that your money is somewhere safe.
• A monetary system becomes strong and preferred when it could allow you to have that sense of security and still be able to spend your money where ever you want.
• One such solution banks came up was introduction of plastic money(credit and debit cards which now evolved into online payment systems), and now a person could bee safe about his money in the bank and carry the plastic money anywhere, in case the plastic money i.e. card or your mobile is stolen, one can easily call and disable the card and one will never loose anything other tan a very small amount. Also now you could have multiple plastic cards which you could share with your family and allow them to spend from your account nd also set limits and restrictions on everything
• With crypto the issue an issue, we always have to carry the account with us, be it a hardware wallet or in mobile. We needed something with crypto such that your highly secure hardware wallet could lie guilt free in a safe and you could carry out smaller transactions without any issue.

Project Value

What our project Delegated Accounts and Cypto Plastic Money does

• Delegated Accounts and Cypto Plastic Money tries to provide similar ability for crypto accounts by providing a delegator contract for main account and allowing multiple delegates i.e. family members to spend from the main account,
• It also provides full ability to restrict daily limits for amount and number of transactions as well as per transaction limit and time delay between two transaction, also allowing you to monitor who initiated the transactions.
• Next phase involves involvement of NFC transactions, and we are also working on a new type of NFC card based crypto delegated wallet to allow blockchain and tron to go mainstream

Project Info

How we built it

We first created a Delegator contract, could be found on our git repo contract’s section in TronIDE. and toughly tested out its capabilities.

• Delegator contract could be deployed by any main account who wants to add delegates.
• Then user would provide allowance to the Delegator contract to spend money on te accounts behalf, this could be restricted based on user’s preference, and could add another security layer.

-Then user could add as many delegates as he wants and provide separate name and values of daily limits for amount and number of transactions as well as per transaction limit and time delay between two transaction.

These delegates could be an wallet based account without restrictions

• Then delegates could use our delegates sections to see their limits, and carry out transactions of sending USDT form the section, without requiring to have any available resources
• If a delegate account is compromised or stolen or lost, one can directly login using main account and disable the delegate account, or can contact admin contract to get the delegate disabled.

We also made a Admin Contract to manage addresses of all delegate accounts, and allow disabling delegates without having access to main account in cases you are travelling, etc.

We also created a frontend for accessing the same using react and tronweb

please note this is our first step towards creating actual plastic crypto in form of nfc card, We have the finalized the RTL designs for a IC , with NFC capabilities, and could sign wallet transactions on chip, and will be using delegator contracts. The chip is now in Verifications stages and we are reverifying the storage security capabilities for the same. we are in talk with a silicon proven edtech startup “VSD” in India to get our chips taped out, Our team was sponsored for a Complete internship by the startup to understand complete process related to IC design manufacturing, add now we re certified Physical Design Engineer.

• First test batch of NFC and onchip transaction signing capable delegated card should be available with us by next phase of Tron Hackahon

Challenges we ran into

We wanted to showcase the usefulness of delegated account to the community but were much busy with the Development and Testing of the IC design, and complete frontend for this project was built in only few days to be in mainstream community in this hackathon and participate in builder category in next season, while also making sure that we understand community and make necessary changes to the final expected product.

Accomplishments that we’re proud of

We are proud to be able to demonstrate how delegated accounts work and also to keep all the concepts easy to understand for anyone.

What we learned

We learned a lot about multiple technologies, and how we could bring togethers multiple streams to build something great

Project milestone

What’s next for Delegated Accounts and Cypto Plastic Money

• We plan at going main net by start of November
• New Tape out and crypto enabled NFCs with delegated accounts, the first tape out would take approx. 4-5 months, and in the mean time, we would continue to have our software ready for great UI and integrations.
• We would surely love to be active with community as much possible nd integrate the community response,

Tron would be the first chain we would be deploying our delegated crypto plastic cards, as it allows for energy sharing and zero fee transactions, which could be very helpful for the cards

I really like your Delegated Accounts and NFC cards! How will you help new users feel safe using them?

[ArtQuest]

Congrats on your hard work! I just gave your project a like and would appreciate it if you could check ours out and give us some love. Voting opens tomorrow, let’s make it count!

How does the concept of “crypto plastic money” align with the broader vision of mainstream cryptocurrency adoption?

[mahreenzahoor384]

How will the admin contract function in cases of emergency, such as a stolen delegate account, to ensure fast and secure disabling of the account?

[ankitmawle]

Main thing we are trying to accomplish is to decrease the gap between web2 and web3 users, providing web3 users the ability to utilize features available in web2 space. while maintaining all the benefits available inn web3 like, having complete control over their funds, no stopping international borders, decide your own restrictions, completely transparent charges, and best security, and much more.

plus biggest scam happening on traditional plastic money is card shimming, which is not possible with delegated accounts.

[ankitmawle]

as of now we are working on a simple to use ui with minimized manual steps for users to make it more user friendly. still one would have generate their own wallet, and all but we have a plan to solve this issue

This is a future plan, we got the idea from coinbase wallet, where they allow passkey to create wallet, which is stored securely inn your device credential manager. so users could onboard without much worry, but it doesn’t support tronchain as of now.

The usecase though fits quite well with delegated accounts, as you need not worry about loosing these accounts when using it as delegate accounts,

in future we could create a similar wallet extension for tronlink, but as of now we are are just a team of two, and short of time to start working on that.

[ankitmawle]

Most important thing that I think is complete transparency. and complete ownership. we provide the users with complete ownership of delegate accounts, and its the main user account which controls everything, Only thing the admin contract is allowed to do is track your delegates, and delegator contract, and disable a delegate.

How does the concept of “crypto plastic money” align with the broader vision of mainstream cryptocurrency adoption?

users need a faster way to carryout transactions, in India UPI plaid a huge role in allowing people to accept digital transactions and now India is the country making highest number digital transactions in world, ad what UPI provided to general public is a way to directly transact from their main account directly from your mobile with a simple UI and without having to worry about creating a separate wallet, or without having to worry about exposure of their main account.

We are trying to provide a similar approach to crypto

What will it be like for main account holders and delegates to use the Delegated Accounts and Crypto Plastic Money project? Will there be an easy way to track transactions and set spending limits?

[ankitmawle]

As of now spending limits can be set only from main account, if we allow delegates to set their own spending amount, if someone steals a delegate account we do not want to allow them to edit it and increase the risk.

as for tracking the transactions, thank you for this idea, I will surely try to add this in the new UI iteration we are creating

How does the Delegated Accounts and Crypto Plastic Money project simplify cryptocurrency use for families, and what features secure transactions among delegates?
