How Trading Works on Spawn
Trading on Spawn is built around one design principle: execution quality shouldn't depend on how much gas you can afford or how fast your infrastructure is. Everyone trades in the same market, at the same speed, with the same information.
The Mechanics
The Spawn Engine - Spawn's off-chain bonding curve execution layer - handles trade execution. This is what makes the trading experience different from anything on-chain:
Instant execution
Submit a buy or sell and it settles in real time - no block confirmations, no mempool, no waiting. The price you see when you submit is the price you get.
No gas required
Trading on Spawn is gasless. You don't pay network gas or approval transactions to buy or sell. Gas only comes into play if you're depositing or withdrawing from the vault. A 1% platform fee applies to bonding curve trades - see Fees & Economics.
No approvals needed
You don't need to pre-approve token spending before you can trade. You connect, deposit USDC, and you're immediately able to participate.
Live price updates
As buys and sells happen, the bonding curve price moves. Everyone watching sees the same live price. There's no stale state or quote lag during high-traffic periods.
Instant Mode
Instant Mode can be toggled on or off depending on how quickly you want to trade.
When it's turned on, trades execute without confirmation popups. That makes it useful in situations where speed matters and you want to make full use of The Spawn Engine without extra confirmation friction between trades.
When it's turned off, you keep the standard confirmation flow. The feature gives traders control over how aggressively they want to execute in different market conditions.
What You Won't Find Here
No MEV. No bundling. No queue-jumping through gas bids. These extraction vectors are structurally removed from The Spawn Engine - they're not against the rules, they're not possible. See Fairness as Architecture →
