Liquidium SDK

One API. Native Bitcoin. Cross-Chain.

Liquidium gives you a single integration point for lending and borrowing across Bitcoin, Ethereum, and beyond. Your users lend and borrow native assets, across chains.

Why Builders Choose Liquidium

Most cross-chain infrastructure depends on fragmented bridges and wrappers. Liquidium takes a different path: one integration to access BTC, and stablecoin liquidity through a decentralized bridge architecture secured by threshold cryptography.

Native by Design, Cross-Chain by Architecture
Users move between BTC, and stablecoins through a decentralized bridge design. No single party controls custody.
Built for multi-chain expansion
Liquidium's architecture is designed to extend across chains over time. Integrate once, then scale as new routes are added.
One SDK, multiple ecosystems
Access Bitcoin, and stablecoin flows through a single SDK, without stitching together multiple vendor integrations.

The Full Protocol, in One SDK

Everything available in the Liquidium app is available via SDK: supply, borrow, repay, withdraw, position queries, and health-factor monitoring.

Supply action illustration

Supply

Supply collateral and earn yield on native BTC, ETH, or stablecoins.

Borrow action illustration

Borrow

Borrow against supplied collateral without selling your assets. Keep long exposure while accessing liquidity.

Repay action illustration

Repay

Repay debt and actively manage position risk in real time.

Withdraw action illustration

Withdraw

Withdraw back to supported Bitcoin or Ethereum wallets or directly to a CEX or Ledger.

What You Can Build

Most cross-chain infrastructure asks you to trust a bridge. Liquidium doesn't. Every asset that flows through the protocol enters and leaves native, secured by threshold cryptography.

The Liquidium Loop

Give users leveraged exposure in one integrated flow. With a single SDK integration, users can deposit BTC as collateral, borrow stablecoins, and redeploy capital without leaving your product.

  • Single integration, multi-step flow
  • Automated leverage management
  • No manual bridging between apps

Embedded Lending

Embed lending directly into your wallet, exchange, or portfolio app. Users can supply, borrow, and manage positions natively inside your interface.

  • Native integration into your UI
  • Full user journey in one place
  • Native assets in, native assets out

Autonomous Agents

Built for programmable finance. Trading bots, strategy engines, and AI agents can open, monitor, and rebalance positions through API-first execution.

  • API-first position management
  • Real-time monitoring and automation
  • Rule-based automated execution

Custom Vaults

Create managed vault products on top of Liquidium infrastructure. Support treasury, structured, or protected strategies with programmable risk controls.

  • Flexible vault logic
  • Policy-based risk controls
  • Institutional-ready product rails
