Reading Solana… (this view reads the merchant's account live and needs JavaScript; the stored verification of every run is under Live proof)
Step 1 of 3 · You

Three short steps: who you are, how you want the money, and your link. No account and no sign-up. Nothing is kept on a server.
Share a link. Your customer pays with what they already hold. You receive exactly the invoiced USDC in your Solana wallet, or straight into yield, and nothing counts until Solana itself shows it.
One exception, by design: a private payment adds a tag of 0.000001 to 0.000999 USDC on top of the invoice, so Sluice can find it on Solana without Aurora's transaction hashes.
Paid live on mainnet from Base, Arbitrum and Optimism, and from a non-EVM wallet on Tron. Every one of those runs is under Live proof.
The merchant's Solana wallet signs amount, address and how it settles. Change one character and the checkout refuses the link.
USDC on Base, ETH on Arbitrum, USDT on Tron, BTC and more. Connect a wallet, or scan a QR from any wallet or exchange.
The page reads the merchant's balance on Solana itself. A provider's "success" is only a hint. Short, late or failed payments go back to the payer.
For tips, top-ups and a QR on the counter. Each merchant gets a permanent address per network: customers send any amount from whatever they hold, whenever they like, and it arrives as USDC on Solana. Nothing to quote, nothing to connect.
Live on mainnet: on 4 Nov, 1.10 USDC sent on Base to a merchant's permanent address arrived as 1.089777 USDC on Solana 14 seconds later, checked on Solana. It is the first row under Live proof.
Payment rails leave money idle until someone moves it. With Sluice a customer on Base can pay an invoice and, in one atomic Solana transaction run through Aurora Intents Connect, the USDC is supplied to Kamino and the yield-bearing cUSDC lands in the merchant's own token account. The payer's account never holds the position, and the order's reference travels with the deposit, so the payment is findable from Solana alone.
Sluice's fee rides in the same transaction. On these invoices the payer adds 0.5% on top, sent to Sluice's own account in the very transaction that settles into Kamino, so the merchant still gets exactly the invoice. The fee account and the rate are pinned in the checkout, which shows the fee before the wallet opens and refuses a transaction that asks for anything else.
The same rail works without a browser. A Sluice API answers 402 Payment Required with its price in USDC on Solana. The buyer pays from any supported chain and calls again. The server delivers exactly once, only after it has read the USDC credit on Solana, and returns a signed receipt.
A hosted one is live. Ask it for its price:
curl -i https://sluice-api.swiftbotlab.workers.dev/api/report/9cYFzrmHRcsYzLhAWsNemzCy75ZhETn2px4MS8oDDReRThen create an order with your own refund address, send the exact amount it quotes from your own wallet, and call again with X-Sluice-Order. The receipt key is published at /.well-known/sluice.json. Every step, with the headless buyer that checks the quote against NEAR Intents' public record before it pays:
$ python3 cli/sluice_buy.py https://sluice-api.swiftbotlab.workers.dev/api/report/<address> \
