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 USDC_TEST token—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.
USDC_TEST contract addresses
| Network | Contract address | Symbol | Decimals |
|---|---|---|---|
| Polygon Testnet (Amoy) | 0xae1D7d8B36E9AbA7D95A75c69d50b38E7e02A9DD | USDC_TEST | 6 |
| Solana Devnet | 3Dx871keTG3hUZUWDYH4dybsjqX3i2vgvNbWgXQji449 | USDC_TEST | 6 |
When you use an explorer such as the Polygon PoS Chain Amoy Testnet Explorer, use the Polygon Testnet (Amoy) contract address above to find and verify the USDC_TEST token:

When you use an explorer such as the Solana Explorer, use the contract address above to find and verify the USDC_TEST token:

Use USDC_TEST in your tests
USDC_TEST is 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 USDC_TEST on both Polygon Amoy and Solana Devnet eliminates the traditional restrictions of testnet faucets and lets you focus on building and verifying production-scale logic from day one.
