Introduction to Bitcoin Connect
Bitcoin Connect is Lombard's infrastructure platform that enables developers to build Bitcoin products across any chain, protocol, or application. Rather than forcing teams to deploy on a specific Bitcoin L2 or build infrastructure from scratch, Bitcoin Connect provides production-grade tooling that connects native Bitcoin to the broader onchain ecosystem.
The Infrastructure Gap
Bitcoin represents over $2 trillion in value, yet less than 1% exists onchain in productive use cases.
For years, building with Bitcoin meant building on Bitcoin. Developers faced limited options: deploy on sidechains, build on Bitcoin L2s, or use custodial wrappers. Each approach locked teams into closed ecosystems with fragmented liquidity and limited interoperability. Worse, each required teams to either operate complex Bitcoin infrastructure themselves or accept significant compromises on security and composability.
These architectural constraints made institutional adoption impossible and forced developers to choose between building on Bitcoin or building where their users actually are. Bitcoin Connect eliminates this tradeoff entirely.
What Bitcoin Connect Is
Bitcoin Connect is a comprehensive and evolving developer platform that provides production-grade tools for bringing native Bitcoin to any application. Instead of forcing teams to build on a specific Bitcoin L2 or manage their own infrastructure stack, it offers direct access to the same systems Lombard uses to secure over $3 billion in Bitcoin across 15 blockchains.
The platform handles all the operational complexity of Bitcoin so developers can focus on the core roadmap. Teams integrate once and inherit infrastructure that's been production-tested at institutional scale, with zero downtime and no security incidents since launch.
What It Unlocks
Bitcoin Connect fundamentally changes what's possible with Bitcoin onchain. Developers are no longer constrained by where Bitcoin infrastructure exists as they can build Bitcoin products wherever their users are.
For Applications
Applications can integrate native Bitcoin functionality without hiring infrastructure teams or managing operational complexity. A DeFi protocol can add Bitcoin collateral support. A wallet can offer one-click Bitcoin staking. A trading platform can enable Bitcoin-backed derivatives. The platform provides the infrastructure (like custody, routing, security) while teams maintain complete control over their product experience and user interface.
This means applications can offer Bitcoin deposits that work like centralized exchange flows, integrate native yield generation directly into their products, launch staking products, and build features that were previously impractical or impossible without dedicated Bitcoin infrastructure teams.
For Chains and Protocols
Chains gain access to native Bitcoin liquidity without building bridges or custody solutions from scratch. Protocols can use Bitcoin as collateral to scale their products without operating validator networks or managing cross-chain complexity. Infrastructure providers can offer Bitcoin services to their users through a single integration rather than building each component separately.
The platform handles cross-chain settlement, custody guarantees, and security validation across all supported blockchains. This lets chains and protocols focus on their core value proposition while accessing the Bitcoin liquidity they need to grow.
For Institutions and Enterprises
Institutions can launch whitelabeled Bitcoin products under their own brands with enterprise-grade security built in. They inherit institutional custody controls, audited smart contracts, Proof-of-Reserve verification, and operational guarantees from infrastructure securing billions in assets—without building separate custody arrangements or undergoing lengthy security audits for each deployment.
This enables institutions to move quickly on Bitcoin product opportunities while maintaining the security standards and compliance requirements their users expect.
Build Bitcoin Products Everywhere with Bitcoin Connect
Bitcoin Connect provides sophesticated tools connecting native Bitcoin to every application, enabling teams to launch Bitcoin products wherever their users are.
What teams can do with Bitcoin Connect:
Onboard Native BTC Deposits directly into the Application (like a CEX)
Offer native Bitcoin yield, including Vault & staking products
Launch whitelabeled Bitcoin products under their own brands
Enable Bitcoin as collateral for lending & Derivatives Products
Innovate with BTC Products without sacrificing security or distribution
Who Bitcoin Connect Is For
Bitcoin Connect supports teams building across the Bitcoin product spectrum, including:
DeFi protocols integrating canonical BTC assets
Chains launching with native or whitelabeled Bitcoin assets
Fintech platforms offering Bitcoin yield or investment products
Institutions, custodians, and staking providers integrating onchain Bitcoin strategies
Each team selects the builder tool that best matches its technical and operational requirements.
Builder Tools Available within Bitcoin Connect
The Lombard SDK (Available today)
The Lombard SDK is the first builder tool released under Bitcoin Connect.
It provides a complete, deployment-ready toolkit for integrating established Bitcoin assets and infrastructure directly into applications. The SDK exposes the same capabilities Lombard operates internally to issue, secure, and manage Bitcoin at institutional scale.
If Lombard can offer a Bitcoin capability in production, teams integrating the SDK can offer the same capability - without building or operating Bitcoin infrastructure themselves.
Lombard SDK
Complete SDK documentation covering installation, configuration, wallet integration, and all available actions. Includes code examples, TypeScript interfaces, and implementation patterns for Bitcoin staking, deposits, and vault deployments.
SDK FAQ
Quick answers to common integration questions covering setup, Partner IDs, wallets, SDK patterns, testing, security, and support. Reference guide for technical and operational questions.
The SDK Playground
Live testing environment to configure flows, simulate operations, and generate SDK code before deploying to mainnet. Test Bitcoin integrations without touching production.
Builder Support
Integration assistance and direct access to the Lombard team via Telegram. Get help with architecture review, debugging, and production escalations.
Additional Builder Tools (Coming Next)
Bitcoin Connect is an evolving developer platform that will expand with additional tools that support different integration patterns, including:
APIs for direct, server-to-server integration and custom orchestration
Widgets
Additional builder tools designed for new Bitcoin workflows and product abstractions
