Ultraner Vault
LivePay safely. Release on delivery.
The buyer's money is locked the moment the escrow is created and only moves when they release it. If something goes wrong, they dispute it and a person at Ultraner decides.
What it does
Escrow: the buyer pays, the money is held, and released to the seller on delivery.
Hold a payment between two Ultraner wallets until the buyer confirms delivery. The buyer can release, dispute, or ask for a refund, and disputes are resolved by a person.
Held, not spent
Funds leave the buyer's balance into escrow and cannot be used elsewhere.
Release by the buyer
Only the buyer can release, so the seller is paid when the deal is done.
Disputes
A disputed escrow is reviewed by Ultraner staff, who release or refund it.
Across currencies
A buyer and seller in different currencies are converted at release.
How it works
- 01
Create
The buyer names the seller's phone, the amount and the condition.
- 02
Deliver
The seller sees the money is held and delivers.
- 03
Release
The buyer releases, and the seller's wallet is credited.
