• Add test USDFC to your wallet

Prerequisites

• A web3 wallet (like MetaMask) installed and have your wallet address

2. Enter your wallet address

3. Complete any verification steps required by the faucet

4. Request tFIL (you will receive 100 tFIL twice a day)

5. Wait for the transaction to complete (this usually takes a few minutes)

Step 3: Mint Test USDFC Using tFIL

Now that you have tFIL and are connected to the testnet application, you can mint test USDFC.

1. On the USDFC testnet application, navigate to the "Trove" section and click "Open Trove"

2. Enter the amount of tFIL you want to use as collateral

3. The application will calculate the amount of USDFC you can mint based on your collateral

Step 5: Closing Your Trove

Most cases, 'Adjust' should allow withdrawing collateralized FIL, but if you no longer need to use USDFC system, you can close your trove and you can reopen a trove again.

Don't forget to repay the borrowing fees. If you wish to close the trove with the USDFC amount you just borrowed, it doesn't work. You should repay borrowing fees. Please get additional USDFC from another account or via swap.

1. On the Dashboard page, navigate to the "Trove" section

2. Click "Close Trove" button

3. If you see error message that you need more USDFC to pay borrowing fees, please get it.

4. If you just wish to withdraw FIL as much as possible, you can cancel closing and click "Adjust"

5. Click "Confirm" to send the transaction with your wallet

Closing Your Trove requires repayment of the borrowed amount and fees in USDFC
