# Testnet Faucet

> Get free testnet stablecoins to build and test without spending real money.

The [First Digital Labs Testnet Faucet](https://www.firstdigitallabs.com/testnet-faucet) dispenses test FDUSD and other tokens on supported testnets. Use them to test Prism integrations and Agent Wallet transactions end to end.

## Getting Test Tokens

1. Visit the [First Digital Labs Testnet Faucet](https://www.firstdigitallabs.com/testnet-faucet)
2. Enter your wallet address (your Agent Wallet address or any testnet address)
3. Select the token and testnet chain
4. Request tokens

Tokens typically arrive within a few seconds on testnet chains.

## Using Test Tokens

**Testing Prism integrations:**

* Set up your SDK middleware with testnet chain IDs (e.g., Base Sepolia: `84532`)
* Use test stablecoins to simulate the full x402 payment flow
* Webhooks fire normally on testnet — test your full payment pipeline

**Testing Agent Wallet:**

* Fund your agent wallet with test stablecoins
* Test transfers, swaps, and commerce payments without risk

## Testnet Chains

| Testnet | Chain ID | Mainnet Equivalent |
| - | - | - |
| Ethereum Sepolia | 11155111 | Ethereum |
| Base Sepolia | 84532 | Base |
| BSC Testnet | 97 | BSC |
| Arbitrum Sepolia | 421614 | Arbitrum |

For native gas tokens (testnet ETH, etc.), use the respective chain faucets (e.g., [Base Sepolia Faucet](https://www.coinbase.com/faucets/base-ethereum-goerli-faucet)).
