Predy v2 Doc
Testnet Setup

Predy is deployed on the Aribtrum Rinkeby testnet, so you can try out trading without risking your own money. This guide will get you started by teaching you to connect to the network and get the ETH and USDC you'll need to start trading.

The first thing you'll need to do is add the testnet to your wallet, here's the easy way to do this.
  1. 1.
    Navigate to and connect your wallet.
  2. 2.
    Enable the Testnets setting.
  3. 3.
    Search for Arbitrum Rinkeby.
  4. 4.
    Click Add to Wallet.
Alternatively, if you want to add the network to your wallet manually, here's the details you need.
Network Name
Arbitrum Testnet
Block Explorer URL

First you'll need some ETH to use for gas.
  1. 2.
    Enter your wallet address.
  2. 3.
    Click Send me ETH.
Now you should have 0.5 ETH in your Arbitrum Rinkeby Wallet.
Note: If you are having issues with the faucet, you can also use one of these faucets:

Now we need some USDC to be able to trade with on Predy. Make sure you've changed your wallet to Arbitrum Rinkeby, note that on Metamask, you may need to enable test networks to be able to select it.
Note: We previously used the Aave faucet, but they recently changed the USDC contract on Rinkeby. We'll eventually have an easier solution, but it's good to learn to use Etherscan anyway!
  1. 1.
    Follow this link, it will take you to the Etherscan page of the USDC contract. If you are not on the Write Contract page already, go to Contract then Write Contract.
  2. 2.
    Click Connect to Web3 and approve the connection in your wallet.
  3. 3.
    Now scroll down through the functions to 5. mint and enter a value here. USDC has 6 decimals, so 1000000 is $1 and 10000000000 is $10000.
  4. 4.
    Click Write and approve the transaction in your wallet, once the transaction is confirmed, you'll have freshly minted USDC in your wallet.
Note: If you want to display the tokens in your wallet, the USDC address used by Predy is 0xF61Cffd6071a8DB7cD5E8DF1D3A5450D9903cF1c.

Now you have everything you need, you can follow the Quick Start guide to make your first trade.
