- A bug allowed 32 wallets to claim 623 million PYBOBO within four seconds.
- The event nearly drained the entire 625 million reward pool almost instantly.
- The flaw is linked to an OKB price underrun.
The crypto sector suffered another sell-off on Friday, with Bitcoin falling about 10% over the past 24 hours to $81,865 at the time of reporting.
Global cryptocurrency market capitalization stands at $2.81 trillion after the roughly 10% decline in the last day.
Amid the broader downturn, OKX’s native token was hit particularly hard as the drop coincided with fresh scrutiny of OKX after an unexpected contract flaw in its recent Boost campaign.
The planned PYBOBO token distribution drained almost the entire reward pool within four minutes — and it was not the enormous consumer demand initially suspected.

Token OKX underperformed the broader cryptocurrency market over the past 24 hours.
At the time of writing it had fallen from $115 to $94, registering a drop of more than 18% on the daily price chart.
OKB faced intensified selling pressure as reports of the contract failure spread.
Four-second bug empties 99.68% of rewards
On-chain statistics show 32 addresses claimed 623 million PYBOBO tokens, nearly wiping out the full 625 million allocated for the distribution event.
Most strikingly, the sweep took only four seconds, surprising both the team and participants.
Investigation indicates a multifunctional mechanism within the OKX Boost claim contract permitted abnormal, rapid claims, allowing a small set of addresses to obtain far more PYBOBO tokens than intended.
OKLink identified a specific wallet that ended up holding 37.847 million tokens, worth about $18,600 at the time.
Remarkably, 99.68% of rewards were gone before the issue was noticed.
The incident appears to have been an unintended contract behavior that pushed distributions well beyond the intended limits.
OKX Wallet pauses claims pending investigation
The team acknowledged the problem shortly after reports emerged and confirmed a pause on PYBOBO claims until the contract issue is resolved with the project issuer.
Claiming for PYBOBO rewards will be postponed.
We’ll provide updates here once the issue has been resolved.

The temporary pause is intended to prevent further potential damage while the project undergoes review.
The team said it will publish updates as the investigation progresses.
The incident sent shockwaves through the OKX ecosystem and helped trigger the sharp selling pressure seen in OKB.
OKB price outlook
OKX’s token hit a daily low of $94 after losing the psychologically important $100 level.
It fell from a daily high of $115 and lost more than 18% of its value in the past 24 hours.
OKB saw daily trading volume increase by roughly 100%, signaling heightened speculative activity.
The digital token will likely decline further before regaining a stable footing, as sellers remain dominant in the current market environment.
