When it comes to handling exploits, lots of platforms do different things. Some disappear. Some issue a statement and refuse to help affected users. Some do what they can. A few make right to their users. The JulSwap platform is one of the few who claim they weren't breached, despite the evidence clearly on the blockchain. Despite their insistence they did nothing wrong, volume and liquidity seem to be down lately.
This is a global/international case not involving a specific country. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]

This is a global/international case not involving a specific country.
The background of the exchange platform, service, or individuals involved, as it would have been seen or understood at the time of the events.
Include:
- Known history of when and how the service was started.
- What problems does the company or service claim to solve?
- What marketing materials were used by the firm or business?
- Audits performed, and excerpts that may have been included.
- Business registration documents shown (fake or legitimate).
- How were people recruited to participate?
- Public warnings and announcements prior to the event.
Don't Include:
- Any wording which directly states or implies that the business is/was illegitimate, or that a vulnerability existed.
- Anything that wasn't reasonably knowable at the time of the event.
There could be more than one section here. If the same platform is involved with multiple incidents, then it can be linked to a main article page.
The Reality
This sections is included if a case involved deception or information that was unknown at the time. Examples include:
- When the service was actually started (if different than the "official story").
- Who actually ran a service and their own personal history.
- How the service was structured behind the scenes. (For example, there was no "trading bot".)
- Details of what audits reported and how vulnerabilities were missed during auditing.

Ultimate Outcome
What was the end result? Was any investigation done? Were any individuals prosecuted? Was there a lawsuit? Was any tracing done?
Total Amount Recovered
There do not appear to have been any funds recovered in this case.
What funds were recovered? What funds were reimbursed for those affected users?
Ongoing Developments
What parts of this case are still remaining to be concluded?
Prevention Policies
In general, many smart contract exploits occur because the contract relies on a limited market place to determine the price of an asset.
By instead relying on a proper oracle, this particular exploit could be avoided.
In a more general solution, storing the majority of funds in an offline multi-signature arrangement would keep them safe. Smart contracts should be thought of similarly to hot wallets.
