Inspiration

Since blockchain is trustless and wallet addresses are so long and weird we would not make out to who are we sending tokens. It was hard to get some wallet addresses that we need to copy and paste into the wallets to make payments and still be clueless about who is getting tokens. In India, UPI is really amazing technology that gives out an id that is connected to bank accounts and when you make a payment to a certain UPI id, the money gets transferred to the bank account directly. So I wanted to build something like that in web3 that will allow us to have a little more trust in the blockchain.

What it does

With Notans, you create your own page that will act as a mediator for token senders to know who is getting tokens. You can link your wallet address to that page and update the wallet address if you lose it. You can share your page on social media or publications and not worry about updating your wallet address everywhere.

How we built it

  • We used Solidity to write smart contract.
  • Front-end is built on Nextjs and tailwind css
  • We are using firebase for authentication and basic data storage
  • Deploy site on varcel

Challenges we ran into

  • Initial challenge we found was actually starting the project. We had no idea how this turns out
  • Second was picking up the technologies we want to use
  • One issue we faced was with the Image upload and display on the dashboard since web3.storage has a different URL for each content
  • A biggest issue that I'm facing right now is not able to transfer tokens which we'll solve pretty soon

Accomplishments that we're proud of

  • Writing smart contract and implementing a stable coin transfer
  • Making it easier for user to actually make payments in crypto

What's next for Notans

  • Web3 community and early adopter may wanna try this
  • This could work great with organization payrolls handling payments in crypto
  • If it makes out to be a startup then partner up with some publications to allow a content creators to get paid in crypto easily
