# RociFi launches on Kovan Testnet By [RociFi](https://paragraph.com/@rocifi) · 2022-03-30 --- After a few weeks of battle-testing with [RociFi community,](https://discord.com/invite/tGgKkSqHZz) we are excited to share that [RociFi is available for everyone to try on Kovan Testnet](https://roci.fi/app/markets)! RociFi is building decentralized credit economy with transferable, blockchain-native credit scores designed to facilitate zero and under-collateralized lending. At its core, the protocol leverages machine learning algorithms for scoring on-chain data and decentralised identity data points to effectively facilitate under-collateralized loans via the blockchain. Read more about RociFi’s vision statement [here](https://blog.roci.fi/rocifi-a-new-multi-chain-defi-primitive-for-zero-and-under-collateralized-lending-based-on-709daf186d54). This release demonstrates core functionality of the future RociFi product on Ethereum blockchain. For the testing purposes, the release is done on Kovan Testnet where users can lend and borrow test tokens. ![](https://storage.googleapis.com/papyrus_images/d5abb8d4d7f30103ac17e61eb2f4f16abefb2c4ad1e172107324fa5bd46b4bbf.png) ### The key functionalities of the release * Connect wallet in Chrome, Brave or Firefox desktop browsers via Metamask and mint your personal Non-Fungible Credit Score ([NFCS](https://kovan.etherscan.io/address/0x0e0fd2228f789Da59e8059114C9FCfb945B04237)) for the bundle of connected addresses. [NFCS](https://kovan.etherscan.io/address/0x0e0fd2228f789Da59e8059114C9FCfb945B04237) is minted on Kovan * Mint [NFCS](https://kovan.etherscan.io/address/0x0e0fd2228f789Da59e8059114C9FCfb945B04237) token preferably for the wallet that has good balance and history of DeFi activity (borrowing, liquidity provision, DEX trading) on the Mainnets of EVM-compatible chains: Ethereum Mainnet, Avalanche, Moonriver, Polygon, Arbitrum, BSC, Fantom, Optimism * Generate your personal credit score for your NFCS. RociFi Credit Scores are from 1 to 10, where 1–6 — are the best scores that would give access to the undercollateralized lending. Read [here](https://blog.roci.fi/rocifis-defi-credit-scoring-terminology-67109d2114ab) more on RociFi’s scoring terminology * Deposit to various risk-based testDAI, testUSDC and testUSDT pools and earn interest on your stablecoins * Borrow stablecoins against your testETH and testWBTC with the rates that depend on your score. Take 2–3 loans of different configurations and track their performance over time * Withdraw your lending position anytime and cash out interest earnings * Do repayment of your loans * Review the actual status of your lending and borrowing positions via Dashboard * Manage collateral holdings on the platform * As a test, you can also miss repayment of the loan and try the experience ### Set up 1\.

Borrow operation has failed. What to do? * Most likely the reason is that Chainlink oracle that RociFi is using has run out of LINK. You can help the whole community to unblock Borrow flow by doing following steps: * Check balance of Chainlink oracle here: [https://kovan.etherscan.io/address/0xfbbbddbb2b53e50400c0339474323f8b2a3e6939](https://kovan.etherscan.io/address/0xfbbbddbb2b53e50400c0339474323f8b2a3e6939). * If it is low, connect your wallet and mint it here: [https://faucets.chain.link/kovan](https://faucets.chain.link/kovan) (select ‘LINK’) * Then send minted LINK from your Kovan wallet to 0xfbbbddbb2b53e50400c0339474323f8b2a3e6939 Thank you! 🙏 2\. I wanted to get test tokens (testDAI, testUSDC etc) but faucet does not work. What to do? * Most likely the reason is that faucet has run out of ETH to pay for transaction costs. Help the community to fix the faucet by doing the following steps: * Mint ETH on Kovan here: [https://faucets.chain.link/kovan](https://faucets.chain.link/kovan) (select ‘ETH’) * Send minted ETH to 0x42446E8d0873dCb7c5DDf649DBEEa6538b8F9f05 Thanks! 😍 3.If you have any issues or questions regarding Testnet usage, please reach out for help in RociFi Discord. ### Feedback We are very much looking to receiving your feedback! It’d be great if you would sum up your feedback, impressions about the product and wishes about the improvements and let us know in the Feedback channel in RociFi Discord: [discord.gg/tGgKkSqHZz](http://discord.gg/tGgKkSqHZz). ### Known limitations and issues * Accessing Application from Ledger wallets is not supported * ETH Collateral price is hardcoded and set to 2700 USD * Only desktop experience — using application on mobile is disabled * LTVs and APRs values are ‘dummy’. They will be different in the final mainnet product * Only full loan repayment and full withdrawal are possible * By default, repayment does not do collateral withdrawal; collateral withdrawal needs to be done explicitly via “Collateral” tab * During the liquidation of the overcollateralized loans, part of the ‘excessive’ collateral that is higher than LTV=100%, will not be returned to the borrower ### Testnet Instructions in Chinese 有关中文说明，请参见此处：[https://mirror.xyz/0xbEE3C272ad4215cb352291af334dDC014BB3c20b/lO2AtgnMI-Bmw-57o2ll6zxs\_mb57bxwAzmAZdjGUMg](https://mirror.xyz/0xbEE3C272ad4215cb352291af334dDC014BB3c20b/lO2AtgnMI-Bmw-57o2ll6zxs_mb57bxwAzmAZdjGUMg) _RociFi is the Layer 1 for a permissionless, multi-chain web3.0 credit economy._ * _Follow us on Twitter:_ [_https://twitter.com/rocifi_](https://twitter.com/rocifi) * _Join our Discord:_ [_http://discord.gg/tGgKkSqHZz_](http://discord.gg/tGgKkSqHZz) * _Join us on Telegram:_ [_http://t.me/RociFi_](http://t.me/RociFi) * _Read our Blog:_ [_blog.roci.fi_](https://blog.roci.fi) --- *Originally published on [RociFi](https://paragraph.com/@rocifi/rocifi-launches-on-kovan-testnet)*
