How It Works
For traders
No single exchange wins every trade. Rankings change by size, pair, and timing. Pennysia compares connected venues on each swap and selects the best quote after gas and fees.
Pennysia sends your swap to 30 exchanges at once and picks the best quote after gas and fees.
One request across connected exchanges. The best quote is selected.
Steps
- Broadcast: same request to all connected exchanges
- Compare: rank by net output after gas and fees
- Execute: you sign; Settlement runs the winning route on-chain
Some routes use CoW Protocol, SODAX, InstaSwap / RocketX deposit-address, or other paths. The app shows the type before you confirm.
| Single exchange | Pennysia | |
|---|---|---|
| Quotes | One venue | 30 in parallel |
| Failed routes | Manual retry | Auto-fallback (when enabled) |
| Your effort | Compare platforms | Enter swap and confirm |
Swap at app.pennysia.com or read the Swap Guide.
Trade features
Auto-fallback
Retries the next best SYNC route in the same transaction if the first fails. Enable in swap settings.
Worst Acceptable Price (WAP)
Floor price for your swap. Execution worse than your WAP reverts. Set in swap settings (gear icon).
Deadline
Max wait time before the transaction expires. Useful during congestion.
Price impact and slippage
Price impact is how much your trade moves the pool price. Slippage is the gap between quote and fill. Pennysia shows impact before you confirm. WAP protects against excessive slippage.
Gas-aware routing
Quotes with high gas rank lower even when the headline output looks better.
Source toggles
Disable individual exchanges in settings. Disabled sources are skipped.
30 exchanges, 12,400+ tokens. Full list: Tokens and Liquidity.
For exchanges
Pennysia is a swap marketplace, not a competing exchange. Each trade sends the same quote request to all connected venues, and the best rate is selected. Integration is free and reduces the cost for new venues to reach traders.
