Sandbox Testnet Currencies
Overview
Testnet faucets typically only drip small amounts of tokens to prevent abuse, which severely limits testing scenarios that involve larger transactions or complex workflows.
For the Sandbox, Noah deploys its own testnet tokens (such as USDC_TEST, EURC_TEST, and PYUSD_TEST)—also used throughout the developer journeys—so you can conduct comprehensive testing with realistic transaction volumes, stress-test applications properly, and simulate real-world scenarios without repeatedly waiting for faucet refills.
Sandbox Cryptocurrency Naming Convention
Be aware that CryptoCurrencies used in the Sandbox always have a _TEST suffix, such as BTC_TEST and USDC_TEST.

Celo Network Migration: Noah has migrated from Celo Alfajores to Celo Sepolia testnet. The Alfajores testnet is deprecated and should no longer be used.

Use Testnet Tokens in Your Tests
Noah's testnet tokens (USDC_TEST, EURC_TEST, PYUSD_TEST) are not available through public faucets. Instead, request the desired amount from your Noah account manager; they can transfer enough tokens for you to:
- Run high-value payment or payout flows
- Perform bulk and stress tests
- Validate FX and refund scenarios
- Replenish balances without cooldowns or "drip" limits
Leveraging Noah's pre-deployed testnet tokens eliminates the traditional restrictions of testnet faucets and lets you focus on building and verifying production-scale logic from day one.
