1 CASH = 1,000,000 base units. Use base units when constructing on-chain transactions.

## Integrating CASH

CASH works like any SPL token. See the Solana documentation on [tokens](https://solana.com/docs/tokens) for program-level behavior. If your app already handles USDC or other SPL transfers, the same code applies with the CASH mint address above.

### Accepting CASH with x402

The [x402 protocol](https://x402.org) lets you gate HTTP endpoints behind payments. When a client hits a protected route, the server responds with HTTP `402` and payment requirements. The client signs a CASH transfer and retries with proof of payment.

See the community [x402 CASH facilitator](https://github.com/adamdelphantom/x402-cash-facilitator) example for a forkable facilitator service and protected Express server you can adapt.

## Devnet

Devnet CASH tokens are available for testing. [Contact developer support](https://docs.google.com/forms/d/e/1FAIpQLSeHWETFkEJbHQCF-lnl1AHmVQPuyfC0HbnxjDjIp6VYV1sBZQ/viewform) with your use case to get a devnet mint address and test tokens.
