Inspiration

Before working on nobank, the team was enthusiastically exploring defi and the vast amount of opportunities. One common problem that we all faced was the complexity in investing the way we wanted - different tokens, different chains, various providers for staking, yield farming, etc. With nobank, we want to simplify this and make defi available to all people without compromising on core blockchain beliefs - decentralization, user empowerment, user custody, financial inclusion for all who want it.

What it does

As nobank, we aim to build a blockchain bank through a non-custodial smart wallet which will be deployed on multiple blockchains. As such, it will allow users to trade crypto assets natively on several chains. Features of nobank will include:

Smart wallet with multiple recovery features
Fiat bridge
Send, receive and trade crypto assets
Build your own savings account
Build your own crypto index (Top 10 assets by market cap)

How we built it

We started working on nobank during the Harmony hackathon "Bridging TradFi to DeFi". During the Chainlink hackathon, we now:

completely reworked our code & stack
deployed on Harmony's mainnet
reworked our smart wallet
built a savings account leveraging a SushiSwap liquidity pool with staking on top
re-engineered swaps & send functionality, using Chainlink price feeds
added a wallet security feature that allows signing a high value transaction with an RFID chip - leveraging a Chainlink oracle
progressed on our vision and spent a lot of time on UI & UX

Challenges we ran into

Chainlink was not fully operational on the Harmony blockchain. We successfully tested our contracts on Ethereum but were not able to replicate on Harmony. We are looking forward to a stable Chainlink deployment on Harmony.

Accomplishments that we're proud of

We professionalized our pipelines, secured our code (e.g. Typescript), implemented Swaps, a Savings Account and Chainlink for RFID validation.

What we learned

A lot and it was a lot of fun!

What's next for nobank

With nobank, we will continue to work on our vision and grow our team. We are dedicated to get independent funding and officially launch as soon as possible.
