FAQ
Is the buyer fully anonymous?
Section titled “Is the buyer fully anonymous?”Not entirely. A buyer who pays from another chain still makes a public deposit on that chain. Nothing public links that deposit to the shop or to what was bought.
Does Lunaz hold my money?
Section titled “Does Lunaz hold my money?”No. The server holds viewing keys only, never spending keys. Funds go to your own shielded wallet.
Is cross-chain payment live?
Section titled “Is cross-chain payment live?”Yes, through NEAR Intents. The assets are USDC, USDT, SOL, ETH and BTC on their main chains. The invoice must be at least 0.001 ZEC. A failed swap is refunded to the buyer’s address.
What if a buyer pays too much or too little?
Section titled “What if a buyer pays too much or too little?”Payments to the same address add up, so a buyer can top up before the invoice expires. Lunaz records an excess as overpaid. A short payment ends as underpaid. Lunaz cannot refund either, because it cannot spend. You refund the buyer.
Which shielded pools does it watch?
Section titled “Which shielded pools does it watch?”Orchard and Ironwood, in both the mempool and mined blocks. A payment shows as detected in seconds. It becomes paid after one confirmation, which takes about 75 seconds.
Do I need to run any infrastructure?
Section titled “Do I need to run any infrastructure?”No. Lunaz is a managed service. We run the gateway, the chain watcher and the cross-chain swaps. You sign in with your email, connect the viewing key of your wallet and call the API.
Where do I find my incoming viewing key?
