How Bybit Uses Geofencing and VPN Detection to Block US Traders
Dec, 19 2024
Quick Takeaways
- Bybit blocks users from the United States through IP‑based geofencing.
- Standard commercial VPNs can usually bypass those blocks.
- Only exchanges that combine IP checks with device‑fingerprinting and traffic analysis stop most VPN traffic.
- Regulators are tightening rules, so Bybit may upgrade its detection soon.
- Traders should weigh the legal risk of using a VPN against the convenience of accessing Bybit.
Ever tried to log into Bybit from the United States and got a “service unavailable” message? You’re not alone. The exchange has built a virtual fence around its platform, and it’s catching a lot of traders off guard. Below we break down exactly how Bybit’s geofencing and VPN detection work, why they’re imperfect, and what that means for anyone trying to trade from a restricted jurisdiction.
Bybit is a global cryptocurrency derivatives exchange that offers spot, perpetual and quarterly contracts for major digital assets. To stay on the right side of U.S. regulators, Bybit’s terms of service explicitly forbid access from the United States and a handful of other jurisdictions. The enforcement mechanism is a multi‑layered geofencing system that leans heavily on IP geolocation.
What is geofencing and how does Bybit apply it?
Geofencing is the practice of creating a virtual boundary around a service and refusing connections that originate outside approved regions. Bybit’s fence looks roughly like this:
- When a user creates an account, the platform records the IP address and matches it to a country database.
- If the IP resolves to a restricted country (e.g., the United States), the sign‑up request is rejected.
- During every login, the same IP lookup runs again. If the address changes to a blocked region, the session is terminated.
- For existing accounts, Bybit monitors IP changes in real‑time and flags accounts that hop between jurisdictions.
This approach is cheap to implement and works well for obvious cases, but it treats the IP address as the sole proof of location.
Why VPNs can slip past Bybit’s fence
Virtual Private Networks mask the original IP and make it appear as if the user is connecting from a permitted country. Bybit’s current detection stack focuses on the VPN IP itself, not the traffic pattern or device fingerprint. Most commercial VPN providers have servers in places that Bybit allows (e.g., Singapore, Estonia, or Germany). When a U.S. trader flips on a VPN, the exchange sees a “good” IP and proceeds with the sign‑in and KYC flow.
The typical bypass looks like this:
- Open Bybit’s website; the platform shows a “service unavailable” error because the real IP is U.S.-based.
- Activate a VPN server in a supported country.
- Refresh the page - Bybit now thinks the user is abroad and shows the sign‑up form.
- Complete KYC using a foreign government ID (often a copy of a friend’s passport) - the platform cross‑checks the document’s issuing country, not the user’s actual location.
- Trade as usual, while Bybit only sees the VPN‑derived IP.
Because the detection relies on a single data point, no matter how many VPN hops you take, you’ll get through as long as the endpoint IP isn’t on the blacklist.
How Bybit’s VPN detection compares to other exchanges
| Exchange | Geofencing Scope | VPN Blocking Method | Compliance Status (US) |
|---|---|---|---|
| Bybit | IP‑based block for US, Canada, Iran, etc. | Basic IP blacklist; no fingerprinting. | Offshore platform, no US license. |
| Binance | Complete withdrawal of US retail services; separate Binance.US. | Dedicated US‑only product, no VPN needed. | Operates US‑legitimate entity. |
| Coinbase | Full US licensing; all users allowed. | Not applicable - platform expects US traffic. | Regulated US exchange. |
| Kraken | US‑licensed; permits US residents. | Not applicable - compliance built‑in. | US compliance achieved. |
| OKX | IP‑based block for US and several Restricted territories. | Uses basic IP checks; reports limited success on VPN detection. | Offshore platform, no US license. |
Notice the pattern: exchanges that have obtained a US license (Coinbase, Kraken) simply stop using geofencing, while offshore platforms rely on the same weak IP checks. Binance sidestepped the problem by launching a separate US entity.
Security implications - the 2024 Bybit hack
Geofencing isn’t just a compliance issue; it also intersects with security. In 2024, Bybit suffered a $1.4 billion breach blamed on North Korean actors. The attackers injected malicious code into the SAFE Wallet front‑end, tricking the CEO’s multi‑signature approval flow. While the hack itself didn’t exploit the geofence, it highlighted how a compromised platform can lose the ability to enforce any access controls.
After the incident, Bybit hired Mandiant to audit its code and improve overall security. One recommendation was to embed more robust device‑fingerprinting into the login flow - a step that would also make VPN bypasses harder.
Regulatory backdrop - why the fence exists
The United States has tightened crypto regulations dramatically since 2022. Agencies like the SEC and CFTC now demand full licensing for any platform that offers derivatives to U.S. residents. Bybit chose the “when all else fails” route - block the location entirely instead of building costly compliance programs.
Legal experts like Jake Chervinsky describe this as a “pretty extreme solution” because it discards a lucrative market. Yet the approach protects the exchange from hefty fines, as seen when Binance paid $4.3 billion to settle with US regulators.
Future upgrades - can Bybit make the fence smarter?
Analysts expect three upgrades in the next 12‑18 months:
- Advanced VPN fingerprinting. By examining TLS handshakes, characteristic packet timing, and known VPN exit node lists, Bybit could flag traffic even when the IP looks clean.
- Device and browser fingerprint correlation. Matching a device’s hardware identifiers to the IP location adds a second data point that VPNs rarely spoof.
- Behavioral risk scoring. Machine‑learning models that watch for rapid country changes, sudden spikes in withdrawal volume, or log‑in from atypical devices can trigger an extra verification step.
Implementing any of these will raise the cost of entry for casual traders using free VPNs, but it will also bring Bybit closer to the compliance standards demanded by regulators worldwide.
Trader checklist - staying compliant (or at least aware)
- Confirm your jurisdiction is allowed in Bybit’s terms of service.
- If you’re in a restricted country, understand that using a VPN violates those terms and could lead to account closure.
- Keep your KYC documents consistent with the IP location you present; mismatches raise red flags.
- Monitor your email for any compliance warnings from Bybit - they often notify users of suspicious activity.
- Consider alternative exchanges that are licensed in your country if you want a risk‑free route.
Frequently Asked Questions
Does using a VPN guarantee I can trade on Bybit from the US?
Most commercial VPNs will let you get past Bybit’s current IP check, but the practice breaches Bybit’s terms of service. The exchange can freeze or close the account if it discovers the mismatch.
What happens if Bybit upgrades its VPN detection?
Advanced detection could block many VPN providers outright, force you to use a residential proxy, or require additional KYC steps. In that case, staying on Bybit may become impractical for US users.
Is Bybit legally allowed to block US users?
Yes. As an offshore platform, Bybit can set its own geographic policy as long as it does not discriminate unlawfully. Blocking a jurisdiction is a common compliance tool.
How does Bybit’s geofencing differ from Binance’s approach?
Binance created a separate US‑only entity (Binance.US) that complies with US law, while Bybit keeps a single global platform and blocks US traffic with IP geofencing.
Can I use Bybit’s mobile app with a VPN?
Technically yes - the app uses the same IP checks as the website. However, app stores may flag the app if they detect systematic policy violations.
Bottom line: Bybit’s geofencing works, but it’s a blunt instrument. If you’re comfortable living with the risk of a terminated account, a VPN opens the door. If you prefer a clean, regulator‑friendly experience, look for a US‑licensed exchange instead.
