[N4] - Lumen 🏅

Building a proof of funds system facilitating underwriting procedures in under-collateralized loans by verifying funds based on a borrower’s attested on-chain assets utilizing zero-knowledge proofs and soul-bound tokens.

Challenges

Web3Modal DeFi Challenge: Making Bank (Without the Banks)

Ranked 5,000 USDC

- We used Walletconnect to solve a real problem in finance - creditworthiness!

Best Use of Polygon

Ranked 10,000 ETH

- What we built is useful for Polygon, especially since Clearpool, Teller and many more credit protocols are on Polygon. - As Polygon grow and onboard emerging market users, what we build will help them get access to credit.

Deploy your smart contract on Scroll

Pool 10,000 USDC

- We have deployed on Scroll. - We intend in the future to use the zero-knowledge feature to generate ZK-proofs.

OpenZeppelin Defender Integration

Ranked 10,000 USDC

- We used Sentinel for monitoring and alerts.  - In case of borrowers moving funds in and out just to fool proof of funds, any large amounts of movement would trigger alerts. - We included a recorded video of how Defender notification would trigger in a demo case.

Build on Base 🔵

Ranked 15,000 USDC

- Coinbase has many consumer users who can very easily be liquidity providers and use our lender dashboard. - Our attestation is a base primitive. - We can further build credit lines and etc. to allow Coinbase users to borrow against their crypto holdings. - We can imagine a future where our attestation is one key part of a larger consumer credit underwriting process that can happen on-chain.

Create a Developer Tool for the AttestationStation

Ranked 9,896 USDC

- Our attestation creates a base primitive for lenders, borrowers and other under-collateralized lending protocols to build upon. - This also helps developers to read/pull data from on-chain in a ready way; smoothing out the UX and lowering the risk for lenders to engage in under-collateralized lending.

Create an AttestationStation App

Pool 11,573.6 USDC

- Our attestation creates a base primitive for lenders, borrowers and other under-collateralized lending protocols to build upon. - This also helps developers to read/pull data from on-chain in a ready way; smoothing out the UX and lowering the risk for lenders to engage in under-collateralized lending.

#BUIDLathon 2023 DeFi Track

Pool 15,000 MATIC

If our product ends up succeeding then will have helped lenders increase their confidence and ability to lend and as a result adding liquidity to credit pools and helping under-collateralized lending and DeFi grow as a whole.


Risk Management

Ranked 20,000 ETH

- Our Proof of Funds addresses counterparty risks. - This can be particularly useful for heavy Binance users in LATAM and Asia. - We can imagine a future where our attestation is one key part of a larger consumer credit underwriting process that can happen on-chain.

Most Useful Web3 Tool

Ranked 2,500 ETH

Web3 is all about transparency and that's what were bringing with our product to the on-chain lending space. The next phase of Web3 credit adoption will be through toolsets that help increase trust amongst risk reduction solutions that today is only truly served in DeFi by collateral. But by increasing the trust of other risk reducing attestations such as proof of funds, more forms of lending will be brought on-chain and and there will be more direct borrower and lender relationships - meaning businesses in places in the world with low access to capital can tap into large pools of capital efficiently.

Spectral.finance's Bounty

Ranked 15,000 USDC

- Our attestation can be an attribute that feeds to how Spectral's MACRO score is generated. - Future vision of using zero knowledge to preserve live wallet balance and allow underwriters to set conditions (e.g. wallet balance and LTV).

Project details

There currently exists no way to verify borrower ownership of on-chain assets or accurately account for liabilities. But verifiable information of a borrower’s funds allow auditors and lenders to make better decisions on managing loans. If they cannot properly verify funds and assess risk - it leads to loss of funds, the reduction of liquidity provision and unfortunate cases such as the FTX crash. Thus we are building a proof of funds system for auditors that validates access and verifies funds based on a borrower’s attested on-chain assets utilizing zero-knowledge proofs and soul-bound tokens. If lenders are able to verify information of a borrower’s funds then it would increase their ability to lend and add liquidity to credit pools and help under-collateralized lending grow as a whole.
