Creating an Advertisement

An advertisement (“ad” for short) is your public offer to buy or sell USDT at a price and terms you choose. Publishing one takes a single wallet signature — this guide covers every field you'll see, plus how to change or take down an ad later.

Every field, explained#

1. 1

   Market (country / currency)

   Pick the local currency and payment rails you want to trade against — this determines which traders can see and match your ad.

2. 2

   Price

   The rate you're offering, in your chosen currency per 1 USDT. This is a rate you set manually — enter a number close to the going market rate so your ad is competitive.

3. 3

   Trade Amount

   The total size of your ad in USDT — this also acts as the maximum a single trade against your ad can be, unless it's already been partly matched down.

4. 4

   Minimum Match Size

   The smallest amount, in USDT, that a taker is allowed to match in one trade. Setting this too high can shut out smaller traders; too low can invite many tiny trades that each cost you a little gas.

5. 5

   Settlement Time Window

   How long a buyer has to pay after a trade is funded, and how long a seller has to review after the buyer marks it paid. Shorter windows move faster but leave less room for slow payment rails; longer windows are more forgiving.

6. 6

   Payment rails

   Check every payment method you're willing to accept or send through for this market (bank transfer, mobile money, etc.) — the more you support, the more traders can match you.

7. 7

   Terms (optional)

   A short free-text note — e.g. “Fast release on confirmation” or “Please include your name in the transfer note.” Keep it specific and actionable.

Bonds and fees, shown before you sign#

Before you publish, Trustfy shows a breakdown of exactly what's being locked: your Ad Bond, Dispute Bond, and maker fee — each as a separate line item, calculated from your trade amount. All three are bundled into the single signature you approve to publish.

Publishing#

1. 1

   Review the summary

   Double-check price, amount, limits, and the bond/fee breakdown.

2. 2

   Sign once

   Your wallet opens with a single request bundling the bond, dispute bond, and fee. Approve it.

3. 3

   Ad goes live

   Your ad appears in the marketplace immediately, status Open, ready to be matched.

Editing an advertisement#

You can edit an ad's price, terms, and payment rails only before it receives its first match. Open it from My Offers and choose Edit — changes save without a new signature since they don't touch anything already locked on-chain.

Trustfy doesn't currently have separate “pause” or “archive” states — Cancel is the way to take an ad down at any point, and a fully matched ad closes itself.

• Setting a price far from the market rate — your ad simply won't get matched.
• Leaving Terms blank when your payment method needs specific instructions (like a reference note) — this causes payment confusion later.
• Setting a very short Settlement Time Window on a slow payment rail, which pressures buyers and increases dispute risk.
