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.
This review marks a major milestone in our efforts to build a secure, transparent foundation for cross-chain decentralized finance.
The review was conducted by Trail of Bits, a security research firm with deep expertise in blockchain and software assurance. The primary review phase was completed in September 2025, followed by a fix review in November 2025 to verify that issues identified in the initial report had been addressed.
During the remediation process, we also implemented several architectural improvements that further strengthened the protocol’s security model. Trail of Bits verified that the original findings from the report were resolved. Because some architectural improvements were introduced during remediation, Trail of Bits recommends a follow-up review covering the final system end-to-end. This is a common recommendation when meaningful improvements are made during an audit cycle. Security is an ongoing priority for Liquidium, and we will continue investing in audits and security reviews as the protocol evolves.
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.
