Operating contract tutorial on the explorer

Note: For which asset you want to operate, you must operate the P-token contract of that asset. P-token represents the deposit receipt of the token in WePiggy
For example:
To deposit ETH, you need to operate the P_ETH contract;
To withdraw USDC, you need to operate the P_USDC contract;
To borrow USDT, you need to operate the P_USDT contract;
To repay ETH, you need to operate the P_BNB contract;

How to deposit

Take USDT as an example

  1. Copy the contract address of pUSDT and paste it into the search box, click to search and then check if it is pUSDT

E002.png

  1. Click “Contract”, then click “Write as Proxy”

E003.png

  1. Click “Connect to web3” below, select MetaMask’s approvement and connect to the wallet

E004.png

  1. Find mint under “Write as Proxy”

E013.png

  1. Enter the amount of tokens to be deposited in the text box.
    All currencies other than ETH must be multiplied by 10 to the power of N, where N is the Decimals
    For example, to deposit100 USDT (decimal:6), enter 100 times 10 to the 6th power = 100000000

E011.png
**Note: On the Ethereum mainnet, you can directly enter the amount of ETH when operating ETH
Other tokens such as DAI, USDT, USDC, etc. need to be multiplied by the number of Decimals, the Decimals can be checked in the corresponding token contract
E006.png

  1. Click “Write”, then check the amount, gas fees and other information in the pop-up MetaMask confirmation, and then click to confirm. After confirmation, the “View your transaction” button will appear, and you can check the operation on the explorer after clicking
