# Sandbox Testnet Currencies

> Noah deploys its own _TEST suffixed tokens in sandbox so you can test large flows without faucet limits. Includes contract addresses.

## 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**, **PYUSD_TEST**, and **USDG_TEST**)—also used throughout the [developer journeys](../recipes/payout/global-payouts-business.md)—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.

## Use Testnet Tokens in Your Tests

Noah's testnet tokens (USDC_TEST, EURC_TEST, PYUSD_TEST, USDG_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.
