Adding the Theta Testnet to your MetaMask wallet opens the door to exploring decentralized applications (dApps) on one of blockchain’s most innovative networks focused on video streaming and content delivery. Theta Network aims to decentralize video and data delivery by leveraging user-powered edge nodes, making it faster, cheaper, and more efficient. The Theta Testnet allows developers and enthusiasts to experiment with smart contracts, dApps, and token integrations in a risk-free environment.
Whether you're a developer testing a new streaming dApp or a crypto user exploring emerging blockchain ecosystems, connecting MetaMask to Theta Testnet is a simple yet essential step. This guide walks you through the complete process—from setting up MetaMask to configuring the Theta Testnet RPC settings and adding test tokens.
Understanding Theta Testnet
Before diving into configuration, let’s briefly explore what Theta Testnet offers:
- Network Name: Theta Testnet
- ChainID: 365
- NetworkID: 365
- Native Token Symbol: TFUEL (testnet version)
- Block Explorer: https://testnet-explorer.thetatoken.org
- RPC URL: https://eth-rpc-api-testnet.thetatoken.org/rpc
- Official Website: https://www.thetatoken.org/
Theta Testnet is an Ethereum-compatible blockchain, meaning it supports Ethereum Virtual Machine (EVM) standards. This compatibility allows tools like MetaMask to connect seamlessly using custom RPC configurations.
Step-by-Step: Connect MetaMask to Theta Testnet
Step 1: Install and Set Up MetaMask
MetaMask is one of the most widely used cryptocurrency wallets, especially for interacting with EVM-based blockchains. If you haven’t installed it yet:
- Open Google Chrome and go to the official MetaMask website.
- Click Download and select the browser extension for Chrome.
- After installation, click “Get Started.”
Choose between Create a Wallet or Import Wallet:
- For new users, select Create a Wallet.
- If you already have a recovery phrase from another device, use Import Wallet.
- During setup, securely store your 12-word recovery phrase. Never share it or store it digitally.
Once completed, your MetaMask wallet is ready for use on Ethereum Mainnet—but we’ll now customize it for Theta Testnet.

Step 2: Configure MetaMask for Theta Testnet
By default, MetaMask connects to Ethereum. To interact with Theta Testnet, you need to add it as a custom network.
- Open your MetaMask extension.
- Click the network dropdown at the top (e.g., "Ethereum Mainnet").
- Select Add Network > Add a Network Manually.
Enter the following details:
- Network Name: Theta Testnet
- New RPC URL:
https://eth-rpc-api-testnet.thetatoken.org/rpc - Chain ID:
365 - Currency Symbol (optional):
TFUEL - Block Explorer URL (optional):
https://testnet-explorer.thetatoken.org
- Click Save.
MetaMask will switch to the Theta Testnet. You may see a "0 TFUEL" balance initially—this is normal until you receive test tokens.
Step 3: Verify Connection to Theta Testnet
After saving the network:
- The network selector in MetaMask should now display “Theta Testnet.”
- Your account address remains the same, but transactions will occur on the Theta blockchain instead of Ethereum.
- Use the Theta Testnet Block Explorer to verify transactions by pasting your wallet address.
You’re now fully connected and ready to interact with Theta-based dApps.
Step 4: Add TFUEL or Custom Tokens to Your Wallet
While TFUEL is the native gas token on Theta, you might also want to add other test tokens deployed on the network.
To add any ERC-20 compatible token:
- In MetaMask, click Assets > Import Tokens.
- Paste the token’s contract address (obtained from the project’s documentation or block explorer).
- The token symbol and decimals should auto-populate.
- Click Add Custom Token, then Next, and finally Add Tokens.
Note: On testnets, real value isn’t involved—these are for testing purposes only.

Why Use Theta Testnet?
The Theta Network stands out for its unique approach to decentralized video delivery. By allowing users to share bandwidth and computing resources, it creates a peer-to-peer content delivery network (CDN). Developers building on Theta can leverage this infrastructure for live streaming platforms, NFT marketplaces, or metaverse experiences.
Using the testnet enables you to:
- Deploy and test smart contracts without spending real funds.
- Simulate user interactions with dApps.
- Debug frontend interfaces connected to Theta’s blockchain.
- Participate in developer bounties or test campaigns.
It’s an essential tool for anyone looking to contribute to or understand the future of decentralized media.
Frequently Asked Questions (FAQ)
Q: Is Theta Testnet free to use?
A: Yes, the Theta Testnet is completely free. It uses test TFUEL tokens that have no monetary value. You can request test tokens from official faucets when available.
Q: Can I lose money on Theta Testnet?
A: No. Since it’s a test environment using fake tokens, there's no financial risk involved in transactions or contract deployments.
Q: How do I get test TFUEL tokens?
A: While official faucets may be limited, developers often distribute test tokens during hackathons or through community channels. Check Theta’s official Discord or GitHub for updates.
Q: Is MetaMask safe for managing multiple networks?
A: Yes, MetaMask securely manages all networks under the same private key. Just ensure you never enter your seed phrase on suspicious sites.
Q: Will my Ethereum Mainnet assets appear on Theta Testnet?
A: No. Assets are network-specific. Your Ethereum tokens remain on Ethereum unless bridged via official cross-chain tools.
Q: Can I switch back to Ethereum after adding Theta Testnet?
A: Absolutely. Use the network dropdown in MetaMask to switch between Ethereum Mainnet, Theta Testnet, or any other added network instantly.
