Testnet Faucets

Faucets are essential for developers to quickly obtain testnet tokens, including native tokens like ETH and stablecoins like USDC, to fund their wallets on blockchain test networks for testing purposes.

Testnet tokens play a critical role in test network environments for two primary use cases:

• Cover network gas fees: Use native tokens like ETH to pay network gas fees for testnet transactions.
• Validate smart contract functionality: Experiment with funds flows in your smart contracts to validate behavior and support for specific digital assets.

Available faucets

Circle provides two faucets:

• Public Faucet: Distributes USDC and EURC on supported blockchain test networks.
• Developer Console Faucet: Distributes native tokens like AVAX, ETH, and MATIC, and stablecoins like USDC. To access the Developer Console faucet, you must log in with your Circle developer account.
