Case Study: Allbridge Classic strengthens cross-chain bridge security with Cossack Labs

Smart contract security audit for Allbridge Classic

Allbridge Classic, a cross-chain bridge enabling asset transfers between Tezos and other blockchains, faced the security challenge of ensuring the consistency and robustness of its Tezos Project smart contracts and infrastructure. They engaged the vendor, Cossack Labs, for a comprehensive security engineering and architecture audit to identify risks and prevent potential threats to user funds.

Cossack Labs conducted a thorough review that went beyond code to analyze transaction flows, gas consumption, and operational security. Their solution included pragmatic security analysis, threat modeling, and providing detailed recommendations for fixes and improvements, such as strategies for secure contract migration and key management. The result was a significantly reinforced Tezos Project, with verified security controls, more consistent functionality, compliance with standards, and optimized storage, which boosted confidence in the bridge's correctness for both Allbridge and its users.
