🤔 What Happens Before a Swap Is Broadcast to the Blockchain?
I used to think clicking "swap" sent something straight to the chain instantly, no real steps in between. Then I actually watched the request cycle happen step by step, and realized there's a whole sequence running before anything gets broadcast at all.
🛠 WHAT RUNS BEFORE YOU EVEN SIGN ANYTHING
- A simulation calculates expected output, fees, and a guaranteed minimum amount based on live pool reserves
- That data gets built into actual transaction parameters — addresses, amounts, a query ID, sometimes referral fields
- Nothing touches the blockchain yet. This is all just preparation happening off-chain first
🔍 THE MOMENT YOUR WALLET ACTUALLY GETS INVOLVED
Only after those parameters are fully built does anything actually reach your wallet. TonConnect passes the prepared transaction over, you review and sign it, and only your signature turns prepared data into something that can actually be broadcast. Before that signature, none of it is final or reversible in any way.
🧾 ONE DETAIL I DIDN'T EXPECT
Every prepared transaction actually carries a validity deadline built into it. If you sit on the confirmation screen too long, the transaction simply expires instead of executing on stale terms.
💬 MY HONEST TAKE
The click feels instant on screen, but there's real sequencing happening behind it — simulate, build, sign, then finally broadcast. Nothing executes until you've actually agreed to specific, calculated terms.
Did you know your entire swap gets calculated in full before your wallet ever even sees it?
