Fees

All fees are shown before you confirm. No hidden charges after you sign.

What you pay

Exchange fees

Set by the winning exchange, not Pennysia. Charged from your trade tokens or as native ETH, depending on the route. Already included in the quoted output.

Network gas

Paid in ETH to publish the transaction. Amount varies by network conditions and route.

How Pennysia earns

Revenue comes from the surplus fee on on-chain sources and partner fees on off-chain sources. There is no flat protocol fee on Settlement swaps.

Surplus fee (on-chain sources)

When execution beats your quote, Pennysia keeps the improvement: 100% of surplus, capped at 10% of output. Zero fee if execution matches or is below the quote.

Example: Quoted 1,000 USDC, executed 1,030 USDC → surplus is 30 USDC. You receive the 1,000 you were quoted.

Partner fee (off-chain sources)

CoW Protocol, UniswapX, and Velora Delta take a partner fee (default 50 bps) paid to the same Settlement fee recipient.

InstaSwap and RocketX (CEX / Private) deposit-address routes do not use Settlement or these partner fees; fees follow each provider’s own breakdown (affiliate / partner fee + referrer attribution).

For exchanges

Integration is free. No listing fees. When flow routes to your exchange, you earn what you would on your own frontend. Pennysia revenue comes from the trader side.
