Crypto and Cash App payments for merchants. Customers pay how they like. You receive stablecoins.

Customers who pay in crypto hold it everywhere: BTC on Bitcoin and Lightning, USDT on Tron, SOL on Solana, stablecoins on a dozen chains. Others just have Cash App. A merchant wants dollars, on one chain, without the price risk.

With Flashnet, a customer pays with whatever crypto they hold, or from Cash App through a Lightning invoice, and you receive a stablecoin on the chain you choose. Price in dollars; the amount converts when the customer pays.

  2. 02The customer pays how they likeOn a phone, the link opens Cash App with the invoice; on a desktop, it shows a QR code. Crypto goes to the address.
  3. 03Flashnet converts itThe payment converts as it arrives and lands as the stablecoin you chose, on your chain.
  4. 04Match it to the orderEvery webhook carries your pay link's label or your own tag, so each payment maps to a sale.

Questions

How do customers pay with Cash App?

They open your pay link. On a phone it hands off to Cash App with a Lightning invoice; on a desktop it shows a QR code to scan. The payment arrives as the stablecoin you chose, on your chain.

Which crypto can customers pay with?

Bitcoin and Lightning, Ethereum and its L2s, Solana, Tron, XRP, Zcash and more, sent to your permanent address on that chain. The live list of routes is public at /v2/orchestration/routes. On Tron, permanent addresses take USDT.

What do I receive?

Pay links deliver USDC, USDT, USDB or PathUSD on Spark, Solana or another supported chain. Crypto sent to a deposit address converts to whichever supported asset and chain you set when you create the address.

How much can a customer pay?

A pay link takes $1 to $50,000 a payment, and Cash App applies its own per-payment limits. Crypto payments follow each route's limits, published at /v1/orchestration/limits.

Where is Cash App checkout available?

Pay links aren't available to residents of New York City. Crypto payments to deposit addresses follow Flashnet's screening and each route's availability.
