Q: How does RociFi work? A: On RociFi borrowers can take USDC & USDT loans. Before taking loans, borrowers must ‘score’ their connected addresses, i.e. mint non-transferrable NFCS (Non-fungible Credit Score) for which a Credit Score will be calculated based on the transactional history of the addresses accounted with connected wallet. Borrowers with good scores can get access to loans with lower collateral requirements.

**Q: What kind of tokens can be borrowed on RociFi and what tokens can be used as collateral?**

A: Currently, users are only able to borrow USDC, USDT and use WETH, MATIC, WBTC, USDT, USDC, DAI as collateral. 
  1. NFCS (Non-fungible Credit Score)

Q: What is NFCS?

A: In order to borrow on RociFi, users need to mint an NFCS token (Non-fungible Credit Score). The Non-fungible Credit Score is an identity token unique to one address (i.e. one seed phrase) and is proof of ownership of all the addresses that are connected to one NFCS. Each NFCS has one assigned credit score. The credit score is generated based on the transaction history of all the bundled addresses: the best score is 1, while 10 is the worst. The better the credit score the higher the likelihood of access to under-collateralized loans.

Q. How can I generate an NFCS credit score?

A: Connect your wallet(s) with Metamask or WalletConnect and click on the “Calculate credit score” in the top right corner of the application to follow the process to add to the bundle and minting. See NFCS minting tutorial, read here: https://www.notion.so/Minting-NFCS-flow-bb14e56a4d044e82b6ba54ed97c6945a

Q: What does ‘add addresses to NFCS bundle’ mean?

A: NFCS allows linking more than one address to one credit score. This provides better user experience of accessing RociFi via a single account as well as a chance to improve credit score if a user’s DeFi transactional activity is spread across several accounts. Users can connect up to 32 addresses in one bundle. In order to connect several addresses to the NFCS bundle, follow this guide: https://blog.roci.fi/nfcs-bundling-tutorial-48363e34baca

Q: Can I add more addresses to the bundle after NFCS has been minted?

A: Yes. See how to do this in this guide: https://blog.roci.fi/rocifi-releases-v1-10-september-week38-update-b57f07ba233b (p.2)

Q. Can a bad credit score be fixed by creating a new wallet?

A: No, so the score depends on various factors such as interaction with various DeFi protocols, DAO participation, as well as the wallet’s age. New wallets are most likely to have a bad credit score (i.e. 10 ) which will improve as the interactions grow.

Q: Can I re-mint existing NFCS?

A: No, it’s not possible to re-mint your NFCS. NFCS is immutable.

Q: Can I delete/burn existing NFCS?

A: No, it’s not possible to delete or burn your NFCS.

Q: Can I transfer NFCS between wallets?

A: No, NFCS is non-transferable.

Q: What is the primary address in the NFCS context?

A: Primary address is the one that has been used to sign NFCS addresses bundle. Users will be able to borrow only after connecting Metamask with the primary address.

Q: Can bundled addresses be seen on-chain?

A: Yes, at the moment it is possible to analyse which addresses have been added to NFCS. We care about privacy of our users and therefore will be working on making this information hidden in the future iterations of the product.

Q: Can I connect addresses having different seeds to one bundle?

A: At the moment it is only possible to bundle different seed phrase addresses from Ledger and Metamask; the other use cases in the nearest future this won’t be possible.
