Adding the Binance Smart Chain (BSC) Testnet to MetaMask is a crucial step for developers and blockchain enthusiasts looking to test decentralized applications (dApps) and smart contracts in a safe, no-cost environment. This guide walks you through the complete process—both automated and manual—while explaining key concepts, best practices, and common pitfalls to avoid.
Whether you're building your first token or debugging a complex DeFi protocol, the BSC Testnet offers an EVM-compatible playground with near-identical behavior to the mainnet, minus the financial risk.
Understanding the BNB Smart Chain Testnet
The BNB Smart Chain Testnet is a parallel version of the BSC mainnet, designed specifically for development and testing. It uses the same Proof of Staked Authority (PoSA) consensus mechanism and supports all EVM-based tools, making it ideal for simulating real-world conditions without spending real cryptocurrency.
Instead of BNB, the testnet uses test BNB (tBNB)—a freely available token with no monetary value. This allows developers to deploy, interact with, and debug smart contracts using realistic gas fees and network latency.
Key features:
- Fully compatible with Ethereum Virtual Machine (EVM)
- Fast block times and low transaction costs
- Integrated with popular tools like MetaMask, Hardhat, and Remix
- Monitored via BscScan Testnet for transaction tracking

Option 1: Add BSC Testnet Using Chainlist (Recommended)
The easiest and safest way to add the BSC Testnet to MetaMask is through Chainlist, a trusted aggregator of blockchain network configurations.
Steps:
- Open your browser and go to chainlist.org.
- Connect your MetaMask wallet when prompted.
- Search for “BNB Smart Chain Testnet” or enter Chain ID 97.
- Click “Add to MetaMask” next to the correct network listing.
- Confirm the network addition in your MetaMask popup.
Chainlist automatically populates all required fields—RPC URL, Chain ID, currency symbol, and block explorer—reducing the risk of errors or malicious network spoofing.
This method is especially recommended for beginners or those concerned about security.
Option 2: Manual RPC Configuration in MetaMask
For advanced users who prefer full control, you can manually input the network settings directly into MetaMask.
Required Network Details:
- Network Name: BNB Smart Chain Testnet
- RPC URL:
https://bsctestapi.terminet.io/rpc - Chain ID:
97 - Currency Symbol:
tBNB - Block Explorer URL:
https://testnet.bscscan.com
Step-by-Step Setup:
- Open MetaMask and click on the network dropdown (top center).
- Select "Add Network", then choose "Add a Network Manually".
- Fill in each field with the values listed above.
- Click "Save" to confirm.
Once saved, your wallet will switch to the BSC Testnet, and you’ll be able to interact with testnet dApps.
⚠️ Always verify RPC endpoints through official sources like the BNB Chain documentation, as public RPCs may change or become deprecated over time.
How to Get Test BNB (tBNB) for Development
After adding the network, you’ll need tBNB to cover gas fees for transactions and contract deployments.
Sources of Free tBNB:
- BNB Chain Faucet: Visit the official BNB Chain developer portal and request test tokens via their faucet.
- Community Faucets: Some developer communities and Telegram groups offer automated tBNB distribution bots.
- Third-party Tools: Platforms like Chainlist sometimes include direct links to faucets upon network connection.
Simply enter your MetaMask wallet address on the faucet website and complete any required verification (such as social tasks or captcha).

Why Use the BSC Testnet?
Choosing the right test environment is vital for successful blockchain development. Here’s why the BSC Testnet stands out:
- EVM Compatibility: Deploy Solidity-based contracts without modification.
- Realistic Simulation: Experience actual network conditions including congestion and gas pricing.
- Wide Tooling Support: Works seamlessly with Truffle, Hardhat, Remix, and more.
- Active Developer Community: Find help, tutorials, and libraries across forums and GitHub repositories.
Using the testnet helps catch bugs early, optimize gas usage, and ensure smooth mainnet launches.

Frequently Asked Questions (FAQ)
Q: Is the BSC Testnet free to use?
Yes, the BSC Testnet is completely free. You can obtain test BNB (tBNB) from faucets to cover gas fees without spending real money.
Q: Can I lose money on the BSC Testnet?
No. Since tBNB has no real-world value, there’s no financial risk involved in testing on this network.
Q: What should I do if MetaMask shows “Network Error”?
Ensure your RPC URL is correct and active. Try switching to an alternative RPC like https://data-seed-prebsc-1-s1.binance.org:8545/ if the current one fails.
Q: How do I switch back to the Ethereum network in MetaMask?
Click the network selector in MetaMask and choose “Ethereum Mainnet” or whichever network you’d like to return to.
Q: Are smart contracts deployed on the testnet permanent?
No. The testnet is periodically reset, so contracts and balances may disappear without notice. Never store value or rely on testnet data long-term.
Q: Can I use the same wallet address on both testnet and mainnet?
Yes. Your MetaMask address works across all networks, but keep funds separate—your real BNB stays on the mainnet.

Final Thoughts
Integrating the Binance Smart Chain Testnet into MetaMask is a foundational skill for any blockchain developer. Whether using Chainlist for simplicity or manual configuration for precision, having a reliable test environment accelerates learning and innovation.
By leveraging tBNB and robust tooling support, you can safely experiment with dApp logic, token standards, liquidity pools, and more—before ever touching real assets.
Always double-check network details from official sources and stay updated on changes to RPC endpoints or consensus rules. With proper setup, the BSC Testnet becomes an indispensable part of your Web3 development toolkit.
Remember: great projects are built not just on code—but on thorough testing.
