Trail of Bits Security Review for Liquidium Cross-Chain Loans

Liquidium has completed an independent Trail of Bits security review of the ICP canisters powering Cross-Chain Loans.

Liquidium completed a Trail of Bits security review of the ICP canisters powering its native cross-chain lending infrastructure. This review examined key protocol components used to support cross-chain loans, with a focus on the systems that manage loan logic, asset interactions, and protocol behavior across networks.

For users, the takeaway is simple: Liquidium is taking the security of cross-chain borrowing and lending seriously before scaling access to more assets and chains. Independent review helps identify risks early, improve implementation quality, and give borrowers, lenders, and partners more confidence in the infrastructure behind the product.

Review Findings & Remediation 

Across the codebase for our ICP canisters, a total of 25 findings were reported during the review process. We reviewed each finding carefully, implemented fixes, and submitted updates for verification. After this process:

• 24 of 25 findings have been resolved
• 1 remaining finding is informational in nature

This outcome reflects the remediation work completed after the review. With only one informational item remaining, the review provides a stronger basis for evaluating the protocol’s current security posture.

What This Means for Users

Security and transparency are core priorities for Liquidium. We believe that rigorous external security reviews are essential not just for internal quality control but for building trust with our users and the broader DeFi community.

This review provides an independent assessment of the ICP canister infrastructure powering Cross Chain Loans. The Cross Chain Loans product enables users to supply assets like native Bitcoin and borrow assets on other chains in a non-custodial way, without relying on third-party bridges or centralized wrapped tokens. The underlying infrastructure is powered by the Internet Computer Protocol’s Chain Fusion technology, which allows ICP canisters to interact directly with other blockchain networks.

What’s Next

With the review now complete and findings resolved, Cross Chain Loans is positioned for broader adoption. We remain focused on continuous improvement and will continue investing in security reviews, tooling, and community education as our products evolve.
