Project Overview 📄​

Overview​

Please provide the following:

  • A brief description of the project.

Vera DeFi is a key component of Vera Protocol, a larger vision to build an open protocol that enables the lending, borrowing and exchange of NFT assets on the blockchain by leveraging hash signatures of object scan, NFC smart tags and decentralized oracles. As a Substrate-based application, Vera DeFi smart contracts will manage unique asset identities, interest, and payment, enabling users to loan assets for token payout.

  • An indication of how you will integrate this project into Substrate / Polkadot / Kusama.

Core Smart contract components will be developed in Ink on substrate. We will research integrating oracles like paralink.

  • An indication of why your team is interested in creating this project.

Like how Bitcoin and Ethereum have enabled trustless decentralized payments of digital assets between strangers, our vision is to enable the trustless retail or exchange of physical goods and assets between strangers without reliance on a centralized marketplace. In light of recent censorships taken by Big Tech oligopolies, our mission is to be an alternative platform for decentralized, censorship-resistant digital commerce and DeFi applications both for digital and real-world assets and physical consumer goods. The Vera team looks forward to working closely with its community to build an ecosystem that empowers and rewards entrepreneurs, inventors, and producers of consumer goods and protect the fundamental human right to buy, sell, or trade property we create and own.

NFT Exchange​

NFT decentralized non-custodial marketplace will facilitate P2P trading between sellers and buyers. The process will be controlled by the ExchangeManager contract. It will provide the following functionality:

createTrade​

Input: NFT address, the tokenID Address in which they want to get paid and the amount Expiration date . Output: Tx ID

This function will be used by sellers to list a new trade opportunity.

When called, the user will be asked to approve the transaction, and the NFTs will be transferred to the smart contract . The function will generate a unique trade ID.

Purchase​

Inputs: Tx ID

This function will be called by buyers to perform a trade by sending the trade ID. The function will get the tokens to pay with from them, they need to approve them first, collect a fee, and send the rest to the seller. At the same time, it will send the NFTs to the buyer. The trade is then marked as completed.

expireTrade​

Inputs: Tx ID

This function can be called by a seller to expire a non fulfilled trade to recover their NFT token.

withdrawFees​

The administrator of the smart contract can call this function to withdraw fees.

ListTrades​

Inputs: None Outputs: List of available NFT for sale with details.

Exchange Transaction

NFT Lending​

NFT Lending functionality is provided by our AssetManager Smart contract.

listToken​

Input: NFT address, the tokenID Address in which they want to get paid and the amount Loan duration Output: Tx ID

This function will be used by borrowers to list a new loan opportunity.

When called, the user will be asked to approve the transaction, and the NFTs will be transferred to the smart contract as collateral. The function will generate a unique trade ID.

lend​

Inputs: Tx ID

This function will be called by investors to perform a trade by sending the trade ID. The function will get the tokens to pay with from them.

withdraw​

Inputs: Tx ID

This function will be called by borrower to pay back their loans with interest and get back the NFT

cancleLoan​

Inputs: Tx ID

This function will be called by the investor to get NFT from the smart contract when the borrower fails to pay back on time.

expireLoan​

Inputs: Tx ID

This function can be called by a borrower to expire a non fulfilled loan to recover their NFT token.

listLoans​

Inputs: None Outputs: List of available NFT for sale with details.

0b.DocumentationWe will provide both inline documentation of the code and a basic tutorial that explains how a user can spin up one of our Substrate nodes. Once the node is up, it will be possible to send test transactions that will show how the new functionality works.
1.NFT LendingContinue the development of our PoC AssetManager contract in Ink to enhance the functionality to fully support the first phase of the user interface. Described above.
2.ExchangeManagerBuild exchange manager to enable non custodial buy/sell of NFT, described above.
3.UI/DesignDesign UI based on the phase wireframe.
4.User InterfaceBuild the UI on top of the smart contract functionalities and based on the design
5.DockerWe will provide a dockerfile to demonstrate the full functionality of the application
6.ArticleWe will write an article or tutorial that explains the work done as part of the grant.

Future Plans​

  • Research and implement oracle integration
  • Integration with physical devices to authenticate physical objects
  • Build more sophisticated decentralized market place
