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.
