PERI Finance dApp Guide for Bug Bounty Program

We will introduce our upcoming dApp details through the following info.
PERI Finance dApp is in the development progress, so you can open the dApp from Kovan testnet and participate the Bug Bounty Program.

All PERI dApp users should have the latest version of the
Metamask Browser Extension installed and to have enough ETH in your wallet to cover transaction fees. (check for the Appendix 1)
We will explain the full status of the Kovan testnet for bug bounty participants and users here, but you can also apply the same procedure for the Ethereum Mainnet for the upcoming dApp.

Add PERI Token on Metamask

If you want to use PERI through Metamask, we suggest adding Token to your wallet first.

Main Page_PERI dApp

This is the main UI of PERI Finance dApp. Users can use stake, burn, and claim in this page, and we will launch additional functions by the next roadmap.

Image: Main Page_My Wallet Detail

PERI dApp set the Target collateral ratio for 400%. This means that if users want to claim for staking, user’s wallet needs to have ample amount of PERI that least exceed the ratio of 400%. Also, If user’s collateral ratio is lower than 150%, the liquidation process will conduct within 3 days. So users need to monitor regularly to check their collateral ratio.


Users can mint PERI’s basic Pynth(PERI Synthetic Asset)pUSD through the staking process.
Click ‘STAKING’ from the main page, then you can choose types of tokens want to stake. We’re currently providing staking tokens; PERI and USDC.

Image: Staking Main Page

If you select “Staking only PERI”, then you can input amounts to mint pUSD.

Images: Staking_only PERI

As shown in the above example, you will mint 100 pUSD by staking 32 PERI.
After launching PERI.Exchange, pUSD will be used for exchanging various kinds of Pynths.

Image: Staking_on Metamask and dApp Alert

Confirm the stake on the Metamask, and you can see the green “success” notification.

Image: Staking_Only USDC

You can also mint pUSD by staking USDC only.

Image: Staking_PERI and USDC Both

If you want to mint pUSD by staking USDC and PERI both, click the “Staking-PERI and USDC”, and input amount to mint pUSD and stake USDC.
The system will display the necessary amount of PERI by inputting the amount of pUSD and USDC.


Image: Burn_Main page

To adjust your C-ratio, you can also burn the minted pUSD.
By burning pUSD, you can refund the staked tokens by selecting PERI, USDC, both PERI and USDC.

While your C-ratio is under the claimable rate
(Target Collateralization Ratio, 400%), click ”Fit to claimable”, dApp will burn the pUSD to adjust the claimable C-ratio(400%) automatically.

Image: Burn_only PERI

For example, you can refund 32PERI by burning 100pUSD as above.
(You have to hold certain amounts of PERI)

Image: Burn_only USDC

Also, “burning USDC only” procedure is working similarly with burning PERI only.
(You have to hold certain amounts of USDC)

Image: Burn_PERI and USDC

By selecting both pUSD and USDC, you can get the USDC and PERI respectively. Input amount to burn pUSD and refund USDC.
The system will display the necessary amount of PERI by inputting the amount of pUSD and USDC.


Image: Claim_Main page and Notice Alert

If your C-ratio is above 400%, you can claim based on staked tokens. This claim is refreshed on every 7 days, so users should regularly check their claim dates.

Appendix 2. Add PERI by Uniswap (v2 only)
