BONE Bridge Reopens as Shibarium Reinforces Security
Shibarium has reactivated BONE transfers on its Plasma bridge, reopening the link between Ethereum and the layer-2 network after a month-long shutdown caused by a validator-key exploit.
The relaunch follows an extensive security overhaul designed to prevent similar breaches.
Core developer Kaal Dhairya confirmed that the rebuilt bridge includes stronger withdrawal controls, new address blacklisting tools, and a mandatory seven-day delay for withdrawals to allow for security monitoring before funds are released. Blockchain firm Hexens independently audited the updated code before its return to mainnet.
The Plasma bridge was originally frozen on September 12 after an attacker used compromised validator permissions to push unauthorized withdrawals through the PoS bridge. Containment measures stopped the loss, but Shibarium temporarily halted all cross-chain activity while rebuilding its systems.
Some stolen assets remain blocked, including KNINE tokens linked to the exploit. The team said it might still offer a conditional bounty for full recovery but ruled out partial returns.
For now, only BONE transfers are active, with other tokens set to follow once testing concludes. Developers are also finalizing a repayment plan for affected users, though details will be shared only after the network’s full restoration.
The new safeguards mark a cautious restart for Shibarium’s bridge infrastructure – slower but far more secure, with the project prioritizing trust and transparency over speed as it rebuilds user confidence.

It started in 2016 with Bitcoin. Like most people at the time, he didn't fully understand it - so he kept digging. Blockchain, tokenomics, the projects, the cycles. That curiosity never stopped, and eventually pulled him into traditional markets too: equities, commodities, macro. Not because he left crypto behind, but because you can't properly understand one without the other. What drives him is straightforward: he wants to know why something is happening, not just that it's happening. Most market coverage stops at the headline - price up, price down, here's a chart. Alex finds that kind of reporting actively unhelpful. If you walk away from an article without understanding the mechanism behind the move, what did you actually learn? He holds a degree in Tourism from New Bulgarian University - not the most obvious path into financial markets, but markets have a way of pulling in people who are simply too curious to stay out. He has authored over 200 in-depth analyses and more than 10,000 articles across crypto and traditional finance. He still thinks every day in markets teaches him something new. That's probably why he hasn't stopped.
