Sandbox Setup

To begin testing crypto payments, you'll need a test wallet and test currency. We recommend using MetaMask with the Sepolia testnet and a simulated stablecoin (TST token). Follow these steps to get set up:

1. Set up a MetaMask Wallet

MetaMask is a browser extension wallet that lets you interact with Ethereum-compatible networks, including testnets like Sepolia.

• Install MetaMask for your browser (Chrome, Firefox, Brave, Edge).
• Open the extension and follow the prompts to create a new wallet or import an existing one.
• If creating a new wallet, back up your seed phrase in a safe, offline location , this is the only way to recover your wallet.

2. Add the Sepolia Test Network

Once your wallet is ready, connect it to the Sepolia network:

1. Open MetaMask and click the network selector at the top (usually shows "Ethereum Mainnet").
2. Click Add network > Add a network manually (or "Custom Network").
3. Enter the following details:
   • Network Name: Ethereum Sepolia
   • RPC URL: https://ethereum-sepolia-rpc.publicnode.com
   • Chain ID: 11155111
   • Currency Symbol: ETH
   • Block Explorer URL (optional): https://sepolia.etherscan.io
4. Click Save. MetaMask will now be connected to Sepolia.

3) Import the TST token (Simulated USDT)

We use the TST token to simulate USDT transactions for sandbox testing.

1. Make sure you are connected to the Sepolia network in MetaMask.
2. Scroll down in MetaMask and click Import tokens.
3. Go to the Custom Token tab.
4. Enter the following:
   • Token Contract Address: 0x3320B95782D61829B615933109328beF282fB020
   • The symbol (TST) and decimals (18) should fill in automatically.
5. Click Add Custom Token, then Import Tokens.

4. Get SepoliaETH for Gas Fees

Transactions on Sepolia require SepoliaETH to pay for gas.

1. Switch MetaMask to the Sepolia network.
2. Copy your wallet address from MetaMask.
3. Go to the Ethereum Sepolia Faucet.
4. Paste your address, complete the CAPTCHA, and submit.
5. After a few minutes, you should see SepoliaETH in your wallet.

❗️

Some faucets may require your wallet to hold a small amount of mainnet ETH (e.g., 0.001 ETH) to prevent abuse.

If you’re unable to get SepoliaETH from the faucet, contact your Orbital Implementation Manager they can help top up your test wallet.

✅ You're Ready to Test

With MetaMask connected to Sepolia, SepoliaETH in your wallet, and the TST token added, you can now test crypto payments on our sandbox environment simulating USDT transactions from end to end.
