LISTING ZVEIN moves from your balance
into order escrow — locked, not spent
SETTLEMENT Buyer pays ZEC on-chain,
straight to the seller's address.
The indexer never touches ZEC.
FILLING Escrowed ZVEIN is credited
to the buyer
CANCEL Escrow returns to the seller
EXPIRY automatically
INDEXER Verifies the chain, escrows ZVEIN,
holds no private keys
A signature proves address ownership. The indexer holds no private keys
and cannot move anyone's ZEC. Orders are signed over the exact payload
shown above — nothing else.
