Trail of Bits Review of Liquidium Cross-Chain Loans
An independent review of the ICP canisters behind Liquidium’s cross-chain lending infrastructure, including the systems that support Bitcoin-backed borrowing across chains.
Liquidium completed an independent Trail of Bits review of the ICP canisters powering its native cross-chain lending infrastructure. The review covered the canister systems behind loan logic, asset interactions, and protocol behavior across networks, including infrastructure used for Bitcoin-backed and cross-chain borrowing.
For borrowers, lenders, and partners, the key takeaway is simple: Liquidium is strengthening the security foundation before scaling access to more assets and chains. The review helped identify implementation risks early, verify remediation work, and increase confidence in the infrastructure behind cross-chain loans.

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
The Trail of Bits review gives users a clearer view into the infrastructure behind Liquidium’s cross-chain loans. These systems support borrowing against assets like native Bitcoin without relying on third-party bridges or centralized wrapped tokens.
The review provides an independent assessment of the ICP canister infrastructure powering Cross Chain Loans. The product lets users supply collateral such as native Bitcoin and borrow assets on other chains in a non-custodial way.
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 complete and remediation work finished, Liquidium can continue expanding cross-chain loans with a stronger technical foundation. Security reviews, protocol hardening, and user education remain ongoing priorities as the product supports more borrowing and lending use cases.
