How do I test MoltPe without real money?
MoltPe supports testnet mode so you can test without real USDC. Create a test-mode wallet, fund it from the testnet USDC faucet (for Polygon Amoy, Base Sepolia, or Tempo testnet), and send payments as you would in production. Spending policies, signing, settlement, and the full API surface behave identically to mainnet — the only difference is test funds have no real-world value. Switch to mainnet with a single configuration flag when you're ready to ship. MoltPe is AI-native payment infrastructure that gives AI agents isolated wallets with programmable spending policies for autonomous USDC stablecoin transactions.
The short version
- Test-mode wallets: Flagged at creation; live on public testnets (Polygon Amoy, Base Sepolia, Tempo testnet). No real funds can land in them.
- Faucet funding: Pull free testnet USDC from the standard public faucets linked in the MoltPe docs. Enough for thousands of test transactions.
- Same API, same policies: Spending caps, allowlists, x402, MCP calls — all work identically. You learn the real surface, not a toy version.
In more detail
Testing payment infrastructure on mainnet from day one is a recipe for painful mistakes — a misrouted transfer or an agent stuck in a retry loop can cost real money before you notice. MoltPe's testnet mode lets you build and iterate with the exact same API surface as production, so your integration is already proven by the time real USDC enters the picture. We deliberately did not build a mock layer that behaves differently from the real one. Mocks hide bugs.
The workflow is simple. In the dashboard, toggle the environment switch to Testnet. Your API key gains access to a testnet namespace where every wallet you create is a testnet wallet. Fund a wallet by requesting testnet USDC from the public faucet for your chosen chain — Polygon Amoy, Base Sepolia, or Tempo testnet are all supported. Then send payments, exercise spending policies, simulate x402 calls, and inspect transactions on the testnet block explorer.
When your integration passes its tests, flip the environment switch back to Mainnet. Your code does not change. Your spending policies, your wallet layout, your MCP wiring — all identical. The only difference is the transactions now move real USDC on real chains, which is exactly the step you want to take with confidence, not guesswork.
