Output amount, impact, fee — if numbers confuse you, shrink size.
Preview before Confirm is the main DeFi screen
On TON DeFi the urge to tap fast is strong: numbers, charts, “hurry”. Yet output preview, impact, and approve decide whether you keep funds. If the preview isn’t readable — shrink size or close.
Check pair, route, slippage, fee, spender. Dust as the first tx. Infinite approve to an unknown contract is a conscious risk, not a default.
Liquidity lies prettily
A thin pool shows a pretty price before your size. After — impact kills the expectation. Don’t trust someone else’s profit screenshot. Price your own exit before entry.
After the trade
Check balance and history. Revoke extra allowance if unused. Don’t run experimental DeFi on the wallet holding main savings. A catalog shows protocol storefronts; the in-client preview is your moment of truth.

A decision glossary for “preview”
When chat says “preview”, translate into actions: what to open, what to verify, what not to sign. “Swap preview: learn to read it before Confirm” is a headline; decisions live in the preview and wallet choice.
Frame: Output amount, impact, fee — if numbers confuse you, shrink size. Anything demanding a seed, prepaid “access”, or an “activation transfer” falls out of frame automatically.
Anchor words: pin, favorites, dust, spender, limit. If the talk has only urgency — you’re in someone else’s script.
Safety contour before any “preview” click
Device updated from normal sources. Wallet client too. Seed not in chats. Experimental balance separated. Not “paranoia before preview” — a table you can work on.
Public Wi‑Fi, foreign PC, screen share — bad background. Move large size to another moment. The topic can wait.
Entry checks: lookalikes next to “preview”
Two candidates beat one. Pin reference beside a feed link. Character by character. Aloud. Icons and “online” don’t count. One letter is enough error cost.
After verify — favorites. Don’t return to global brand search. Clones queue there specifically for “preview”.
Action, preview, aftercare
An action on “preview” without a readable preview is a lottery. State the operation type. Shrink size until it’s boringly clear. Dust. History. Balance.
After: revoke extra approve, delete temporary bookmarks, ensure you didn’t leave a session on a foreign device. The catalog may have helped find the entry; cleanup is yours.
Long distance: “preview” without season drama
Seasons come and go. Habits stay. Weekly short review: favorites, junk tokens, updates. Once a season — a careful look at seed backup without publishing words.
If “Swap preview: learn to read it before Confirm” feels long — that’s intentional. Short taps already belong to attackers. Your edge is a slow Confirm and a calm refusal.
How “preview” links to other ecosystem habits
Even when today’s focus is “Swap preview: learn to read it before Confirm”, seed hygiene, username anti-phishing, wallet separation, and exchange memo care still matter. You don’t need to learn everything at once. You need to not break the base while handling the special case “preview”.
Leave TON Web Search as an entry map. Maps can be closed. Keys and limits cannot.
“preview” practice: three kill-switches
First kill-switch — source. If the entry for “Swap preview: learn to read it before Confirm” didn’t come from the pin or your favorites, you’re already in a higher-risk zone. Second — wallet: experimental for new, main for known and verified. Third — size: dust before volume. Three switches close most everyday failure stories around “preview”.
Reminder frame: Output amount, impact, fee — if numbers confuse you, shrink size. Don’t turn the frame into a “hurry” slogan. Refusing also counts as being on time.
FAQ without fluff (about preview)
**Do I need the main wallet?** Usually no. An experimental limit is enough to learn “preview”.
**What if friends are already in?** Their deposit doesn’t insure yours. Source checks stay yours.
