Trade
Swap any token — get the best rate available across the entire DEX market, with no extra steps.
Most swap interfaces route through a single aggregator and call it the best rate. Pennysia Exchange is different: it queries all major DEX aggregators simultaneously, compares every quote, optimizes the execution path further, and submits the single best result — automatically, on every trade.
You don't pick an aggregator. You don't compare platforms. You just swap.
True Best Rate Swap
- Provably best rate — not best rate from one source, but best rate across the entire market at that moment
- Gas-aware routing — a better quote that costs significantly more gas isn't actually better; the protocol accounts for the full net cost
- Execution reliability — if conditions shift between quote and submission, the protocol handles it; no silent failures at degraded rates
- Zero overhead — one interface, one transaction, no aggregator research required
📖 How routing works under the hood
Pennysia Exchange is an Aggregator of Aggregators (AoA) — a routing layer that sits above existing DEX aggregators and makes them compete on your behalf. See How it Works for details.
Price Impact & Slippage
| Term | What it means |
|---|---|
| Price impact | How much your trade moves the price — larger trades in smaller pools = higher impact |
| Slippage | The difference between your quoted price and the actual execution price |
Price impact is predictable. Slippage also includes price changes from other transactions that happen before yours is confirmed.
Protection Settings
Slippage Tolerance
Set a maximum acceptable deviation (e.g. 0.5%). If the final price is worse than this, the transaction reverts automatically.
Example: Expecting 100 USDC for 0.05 ETH with 1% tolerance → you'll receive at least 99 USDC, or the trade cancels.
Setting it too low may cause failed transactions. Too high exposes you to sandwich attacks.
Deadline
Set a time limit for your transaction. If not confirmed within the deadline, it reverts — preventing execution at stale prices during network congestion.
