PROCESS

Create Quote

Merchant requests a quote with payout amount and asset. ZECRail returns the ZEC price, a unique shielded payment address, and a 15-minute expiry window.

SHIELDED INPUT

Receive ZEC

Customer sends shielded ZEC to the unique address. The payment is private — the sender, amount, and memo are encrypted on the Zcash blockchain.

ENCRYPTED ON-CHAIN

Verify Settlement

Once the ZEC payment is confirmed, the liquidity provider executes the payout on Robinhood Chain. This settlement transaction is public and verifiable on the block explorer.

PRIVACY MODEL

What stays private. What becomes public.

ZECRail is not a trustless bridge or a private Robinhood transaction. The ZEC payment can be shielded, but the settlement is public. Here is exactly what each party can observe.

SHIELDED (PRIVATE)

Sender wallet address
ZEC payment amount (on Zcash)
Transaction memo field
Sender IP address (via Tor/VPN)

PUBLIC (ON ROBINHOOD CHAIN)

Settlement amount and asset
Merchant destination address
Transaction hash and block
Liquidity provider address

PROVIDER OBSERVES

Correlation between ZEC payment and settlement
Exchange rate applied
Payment timing and confirmation speed
Merchant identity (via checkout request)

ZECRail is an independent project. It is not an official Zcash or Robinhood product. The liquidity provider operates as a trusted intermediary between the shielded and public sides of the transaction.
