Jupiter Review
Zero protocol fees, unpublished core code
of 10
Jupiter states plainly that there are zero protocol fees on its swap by default, with integrators able to add their own platform fee. The on-chain aggregator program itself is not published, so the code cannot be inspected.

Zero by default
Integrator fee
Set by integrators via platformFeeBps, e.g. 20 bps = 0.2%

Scores
Each criterion carries equal weight. The overall score is the average of these 5 scores — (9.0 + 2.0 + 4.0 + 4.0 + 3.0) ÷ 5 = 4.4.
Pros
- States zero protocol fees on Jupiter Swap by default
- Integrator fees documented with a worked example, 20 bps for 0.2%
- The default cost position is the clearest of any aggregator here
Cons
- No repository containing the core on-chain aggregator program is published
- Only SDKs and clients are public, most without a licence
- A formal supported-chains statement was not found
- No audits named on the pages we read
The clearest fee statement in the category
Jupiter's developer documentation states that by default there are zero protocol fees on Jupiter Swap, and documents how an integrator may add a platform fee in basis points. A reader knows exactly what the protocol itself takes, which is more than most competitors here disclose.
The code is not there to read
No repository containing the core on-chain aggregator program appears on the official GitHub organisation. What is published are SDKs and client libraries, most carrying no licence at all and a few under Apache 2.0.
For a protocol routing trades across venues, the routing logic is the part a user might most want to inspect, and it is precisely the part not available. Zero fees and closed source is a coherent position, but it is a trust-based one.
