To enhance its security measures further, XLink is expediting its partnership with Ancilia Inc. to boost “real-time on-chain monitoring infrastructure.”

Ancilia played an important role in the recent incident by alerting XLink to the attack, allowing the bridge provider to take swift actions that prevented additional fund losses.

Additionally, XLink is collaborating with Cobo, its BTC custodian, to expand its setup and expedite migrating its web3 key management to the Cobo MPC infrastructure. XLink emphasized that in addition to its partnerships with Cobo, Ancilia, and Kaamel Technology, it plans to announce further partnerships in the future as part of its efforts to enhance the security of its platform.

The company urged users who interacted with the compromised contracts to revoke any approved spending limits as a precautionary measure to mitigate further risks.

In a related incident, Bitcoin layer-2 developer Alex Labs, the creator of the XLink bridge, suffered a separate attack on May 15. Due to compromised private keys, the attacker stole approximately $13.7 million in Stacks (STX) tokens.
