Incidents
- 2024 · Hack: June 2024: a small number of OKX user accounts were drained after attackers bypassed account verification (reported as SIM-swap attacks). The amount was not disclosed. OKX said it had compensated and would continue to compensate affected users; it did not confirm whether every user was repaid. source
- 2020 · Withdrawal freeze: Digital asset withdrawals were suspended from October 16, 2020 while a private-key holder cooperated with a public security bureau investigation. OKX's November 6, 2020 update confirmed the suspension was still in place; withdrawals were reported to have resumed in late November 2020. source

Who OKX fits
A good fit if
- You want reserves checked by an outside firm.
Think twice if
- You live in the US: availability is limited, so check your state first.
- A clean regulatory record matters to you: OKX pleaded guilty in 2025.

About this review
Blocklr has no affiliate, advertising or sponsorship deal with OKX or any other platform, so nothing here was paid for. Scores come from the rules in our review methodology. A fact we could not confirm scores as the lowest tier, which can make a score lower than it deserves. If something is wrong or out of date, tell us and we will check the source and correct it.
