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 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 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 example for a forkable facilitator service and protected Express server you can adapt.

​
Devnet

Devnet CASH tokens are available for testing. Contact developer support with your use case to get a devnet mint address and test tokens.
