Gitcoin Grants Round 10 - Aave Dapp

[sypeer]

Quick recap

Teller is the first DeFi protocol built to evaluate consumer credit risk, and offers cryptocurrency loans that do not require a collateral amount to exceed principal loan value. This is achieved by assessing a user’s credit risk through personal consumer financial data. Consumer data is privately provided to Teller’s Credit Risk Algorithms (CRAs).

Overview

As part of efforts in expanding utilization to users and the Teller mission, we are looking to build on top of our CRAs. Our goal is to inspire developers to build on top of our open credit risk system, initially with dapps, and then so much more!

Bounty

Upto $2500 worth of ETH will be awarded to the winner entry

Challenge Description

Build a Dapp that allows users with undercollateralized loans through the Teller protocol to interact with Aave with four functions:

• Add liquidity to the Aave AMM
• Remove users’ previously provided liquidity
• Borrow funds, linked to a users loan from Aave
• Repay loan from previous borrow

Submission Requirements

• All submissions should be published on Github through pull requests on the Teller protocol
• All code should be MIT licence based and open source
• Tests to be written in typescript
• PRs should be based off the “develop” branch and with the name starting with “feature” followed by a short description of the task: Example - “feature/GR10/aaveDapp/”

Judging Criteria

All submissions will be evaluated by the Teller Finance team, based on the following criteria:

• Code Quality
• Comments!!!! (enough to effectively articulate the code)
• Fully functional
• Gas usage per transaction
• Test coverage and creativity of testing scenarios
• Scope of work (the amount of time spent)
• Bonus - Leverage the dapp with another dapp of your choice

=> A project that uses a factory contract to spawn new loan pools.

=> It combines a browser-based frontend with the ethereum smart contract using web3.js.

*Anyone can create the pool using the form on the application.

*During the creation of the pool, the pool creator needs to fill in the necessary details and, need to choose the lending pool between Aave & Mstable.

*Based on the choice, a new smart contract will get generated using the factory contract. The details of the pool will get stored on the graph using the-graph SDK.

*The participants will be able to join any pool available to participate from the frontend. They need to deposit the collateral amount and, the collateral will generate a yield from the lending platforms (Aave or Mstable).

*The loan auction will start once at least 2 participants will join the pool.

*During the auction, the participant can bid the amount to win the loan if they want.

*The number of the auction will depend upon the total number of participants in the pool.

*The highest bidder will be able to claim the loan, once the auction period will be over.

*The loan amount will be equal to the loan amount - bid amount (the loan amount is also equal to the collateral deposited at the beginning).

*The bid amount will remain stored on the lending pool and it will get distributed among all the participants with yield generated from lending pools after all auctions.

The advantage of this approach is that the last participant gets the loan interest free and on top of that earns interest on the collateral. The interest paid by other borrowers is used to earn an additional interest which is also distributed among all the participants.
