Base Faucet: How to get free Base testnet ETH

Base is an Ethereum L2 built for onchain applications — fast, low-cost, and fully EVM-compatible. To test applications before deploying to production, developers typically rely on a Base faucet to get testnet ETH. Whether you’re building consumer apps, DeFi protocols, or payment flows, you’ll need testnet ETH before anything goes to mainnet.

The Chainstack Base faucet gives you 0.5 ETH every 24 hours with no Twitter gate, no friction. Just sign in, paste your wallet address, and start building.

How the Chainstack Base faucet works

Before you push anything to mainnet, you dry-run the flow — deploy a contract, test stablecoin transfers, fire transactions against a Base testnet RPC, or validate payment and settlement logic. For any of that, you need ETH.

We’re one of the first to ship a Base faucet built for that. It’s tied to your wallet address and lets you claim 0.5 ETH every 24 hours, with no Twitter authentication in the mix. Just sign in, point it at your wallet, and you’re ready to test.

From there, you can use your balance to cover gas on testnet, validate smart contract deployments on Base, or run automated checks in your dev loop. And when you’re ready to go beyond test tokens, you can deploy a Base node in the console and plug into mainnet or testnet RPCs all in one place.

⚠️ Faucet requirements:

To safeguard against misuse, the Chainstack faucet implements two key checks
before disbursing funds:

1. The requesting address must have a minimum balance of 0.08 ETH on the
   Ethereum mainnet.
2. The address should have a history of holding ETH on the mainnet; it should
   not have been recently empty.

These precautions help maintain the integrity of the faucet, ensuring fair and
equitable access for all users.

How to use the Base testnet faucet on Chainstack

Getting test ETH from our Base faucet is simple.

1. Sign in — Log into your Chainstack console.
2. Get your API key — In the console, go to Settings → API keys and copy an active key. You’ll need it to authenticate with the faucet.
3. Open the faucet — Navigate to the Base faucet page and paste your API key when prompted.
4. Enter your wallet address — Paste the address you want to fund.
5. Claim tokens — Submit the claim. You’ll receive 0.5 ETH every 24 hours.
6. Confirm balance — Check your wallet or query your Base RPC endpoint.

Once your wallet has balance, you can use it to pay gas on testnet, deploy contracts, or run integration scripts against the Base testnet. If you need stable, high-performance infrastructure, alongside tokens, you can spin up a Global Node for quick tests or a Dedicated Node for latency-sensitive workloads. Both expose HTTPS and WebSocket RPC URLs that slot straight into wallets, frameworks, or custom tooling.

What you can do with Base testnet ETH

On Base, nothing moves without ETH, even on testnet. ETH pays gas for contract deployments, transaction calls, and anything routed through a Base testnet RPC. That makes a Base faucet the starting point for testing real workloads before going to mainnet. With testnet ETH, you can:

• Test stablecoin settlement flows and payment infrastructure
• Simulate DeFi activity like swaps, lending, and liquidation checks
• Run bots or automation scripts against real RPC responses
• Stress-test AI agents or keeper logic under bursty request patterns
• Backtest protocol logic without risking real funds

Once you’ve got tokens in your wallet, the next step is to connect them to infrastructure you control. In the Chainstack console, you can spin up a Base node, copy the HTTPS or WebSocket RPC URL, and start routing calls through your own endpoint.

Base tooling

Beyond the faucet and nodes, Base provides developer tooling you can integrate into your stack. You can interact with the network using standard EVM-compatible tooling over JSON-RPC, making it easy to work with smart contracts, query chain state, and run automated workflows.

Base works with familiar Ethereum developer tools and libraries, allowing you to reuse existing Solidity code, frameworks, and scripts without custom integrations. For the full set of SDKs, APIs, and integration guides, check the Base tooling docs.

Chainstack also supports Flashblocks on Base — 200ms transaction preconfirmations for latency-sensitive apps.

Wrap up: more for Base builders

Faucet ETH gets you moving, but production-grade stablecoin and payment workflows need more than just gas. On Chainstack, you can run a reliable Base RPC infrastructure to query historical data, debug transactions, and stream state changes over WebSocket connections.

If you prefer starting from code, Chainstack provides examples and reference implementations that show how to interact with Base RPC endpoints using standard EVM-compatible tooling. The Base API refers to the standard Ethereum-compatible JSON-RPC interface exposed by Base RPC nodes.

Between the faucet, stable RPC infrastructure (Global or Dedicated Nodes), and up-to-date documentation, you get an end-to-end setup: test with faucet tokens, validate against production-like infrastructure, and move to mainnet without reworking your stack.
