Liquidium primary sources — 2026-05-01

Project status in this pass

• No canonical standalone whitepaper or litepaper surfaced.
• The clearest current source of truth is the Liquidium site, docs, SDK page, technical docs, security-review disclosure, and public GitHub organization.

Primary-source snapshots

1) Main site overview

• URL: https://liquidium.fi/
• Key excerpt:
  • The homepage describes Liquidium as a place to borrow and lend native Bitcoin against USDT.
  • It emphasizes native-assets-in / native-assets-out flows, no centralized wrapping, and a fully decentralized architecture.
  • The page also links the docs portal, SDK page, app, GitHub org, and a security-review announcement.

2) Docs landing page

• URL: https://liquidium.fi/docs
• Key excerpt:
  • The docs say Liquidium is a decentralized non-custodial cross-chain lending protocol where suppliers provide liquidity and borrowers post excess collateral to access it.
  • The page says assets originate on their native chains and that the system is built on the Internet Computer to support cross-chain interactions without centralized bridges or wrapped-token UX.

3) Technical documentation

• URL: https://liquidium.fi/docs/technical
• Key excerpt:
  • The technical docs say Liquidium is a cross-chain lending and borrowing protocol built on the Internet Computer.
  • They list key features including non-custodial canister-vault asset management, share-based accounting, Aave-style kink interest rates, two-phase execution, and subaccount architecture for privacy-preserving deposit and withdrawal flows.
  • The docs define three primary canisters: Lending Canister, BTC Pool, and ERC Pool.

4) SDK page

• URL: https://liquidium.fi/sdk
• Key excerpt:
  • The SDK page says developers get one API / SDK for lending and borrowing across Bitcoin, Ethereum, and beyond.
  • It pitches embedded lending for wallets and exchanges, leveraged loops, autonomous-agent automation, and custom vault products.
  • The page says the architecture relies on a decentralized bridge design secured by threshold cryptography so assets can move natively rather than via fragmented bridge wrappers.

5) Security-review disclosure

• URL: https://liquidium.fi/blog/liquidium-announces-completion-of-trail-of-bits-security-review-of-icp-canisters-for-cross-chain-loans
• Key excerpt:
  • Liquidium says Trail of Bits completed an independent review of the ICP canisters powering Cross-Chain Loans.
  • The announcement says 25 findings were reported, 24 were resolved, and the one remaining item is informational.
  • The post also notes a recommendation for a follow-up end-to-end review after architectural improvements made during remediation.

6) Public GitHub organization

• URL: https://github.com/Liquidium-Inc
• Key excerpt:
  • The public org shows active repositories such as liquidium-pipeline, staking-canister, staking-app, runes-indexer, and liquidium-recovery-tool.
  • That repository mix suggests Liquidium is shipping protocol-adjacent infrastructure and operational tooling, not only a single landing page or frontend.

Working conclusion

Liquidium is best cataloged as cross-chain lending and liquidity infrastructure. The strongest evidence is the combination of Internet-Computer-based canister architecture, native-Bitcoin / stablecoin borrowing flows, technical docs for the lending system, an SDK aimed at embedded and autonomous integrations, and transparent publication of security-review status.
