Three steps. Nothing left to trace.

  1. 01

    Paste a Lightning invoiceEnter your shielded address

    Get a live quote and a fresh shielded address made for this one payment. No account, no wallet to connect.Pick an amount and get a Lightning invoice, or claim a Lightning address that always lands in your shielded wallet.

  2. 02

    Pay from any shielded walletThey pay from any Lightning wallet

    Scan the QR with Zodl, Zkool or any Zcash wallet. On chain it is one shielded transaction: no sender, no recipient, no amount.Phoenix, Strike, Cash App, anything that speaks Lightning. Nothing about the payment is written to the Bitcoin chain.

  3. 03

    The invoice is paidShielded ZEC arrives

    The gateway pays over Lightning about a minute later and hands you the preimage, the payee's cryptographic receipt.Seconds after the invoice is paid, ZEC lands in your shielded address, with the payer's note as an encrypted memo.

Who sees what. Look it up yourself.

Two real cross-chain moves from October 26, and what the public chains recorded for each.
