What is Coinbase Developer Platform Faucet?
The CDP Faucet is Coinbase Developer Platform's testnet faucet for Base Sepolia, Ethereum Sepolia and Solana Devnet. It gives test ETH, USDC, EURC and cbBTC on the EVM testnets and SOL and USDC on Solana Devnet, from the CDP Portal or the CDP SDK. ETH claims are 0.0001 each, up to 1,000 claims per 24 hours.
How Coinbase Developer Platform Faucet works
The faucet sends test tokens from Coinbase to an address on Base Sepolia, Ethereum Sepolia or Solana Devnet.
Each asset has its own 24-hour cap: ETH pays 0.0001 per claim with 1,000 claims, USDC and EURC pay 1 token with 10 claims, cbBTC pays 0.0001 with 100 claims, and on Solana Devnet SOL pays 0.00125 and USDC pays 1, each with 10 claims. Tokens follow the native ETH, ERC-20 or SPL standards.
In code, the CDP SDK (@coinbase/cdp-sdk for Node.js 22 or later, cdp-sdk for Python 3.10 or later) exposes requestFaucet, which takes an address, a network such as base-sepolia and a token such as eth, and returns the transaction hash. You can fund a new CDP non-custodial account created with createAccount or pass any external address you already control.
How to start with Coinbase Developer Platform Faucet
- Create and sign in to a CDP account at portal.cdp.coinbase.com.
- In the Portal, open Faucets, choose the network and token, paste a wallet address and click Claim.
- For scripts, also create a CDP API key and generate a Wallet Secret, then store CDP_API_KEY_ID, CDP_API_KEY_SECRET and CDP_WALLET_SECRET in a .env file as the quickstart shows.
- New EVM accounts are created on Base Sepolia by default, and you can name another EVM network in the faucet request.
Risks to know before using Coinbase Developer Platform Faucet
- Faucet tokens have no market value, so the risks are operational.
- The quickstart has you keep your CDP API key and Wallet Secret in a .env file; keep that file out of source control.
- The small ETH amount per claim, 0.0001 ETH, means a test suite that burns gas on many transactions can run into the 1,000-claim cap in 24 hours, and USDC testing is capped at 10 claims of 1 USDC in the same window.
