The Arch Unlock

Arch expands what's possible in the Bitcoin ecosystem by providing a user and developer experience previously unattainable on Bitcoin. As the financial infrastructure layer that Bitcoin has been missing, Arch preserves the monetary integrity of pristine BTC while enabling scalable Bitcoin-backed credit and capital markets.

Seamless Bitcoin Wallet Integration

Unlike other solutions that force users away from their Bitcoin wallet, Arch Network's novel Taproot address compatibility account model allows users to access Arch applications directly from their existing Bitcoin wallets:

• Native compatibility: Use familiar Bitcoin wallets like Xverse, Unisat, Magic Eden, and Ledger to interact with Arch applications
• No bridging required: Access Arch functionality without transferring assets to external chains or secondary wallets that introduce additional trust assumptions
• Unified asset management: Manage all your Bitcoin assets (BTC, Ordinals, Runes) in a single wallet interface
• Interoperability: Move seamlessly between Bitcoin applications and Arch-enhanced applications

This deep integration with the Bitcoin wallet ecosystem eliminates the fragmentation of liquidity and attention that has plagued previous Bitcoin extension attempts. By preserving the security model users trust while expanding what they can do with their Bitcoin assets, Arch enables a unified experience.

Flexible Trust Models for Developers

Arch's unique approach gives developers unprecedented flexibility in how they balance Bitcoin's security with modern application performance requirements:

• Customizable security models: Choose the optimal point on the trust spectrum for each application or transaction type, breaking free from Bitcoin's security vs. innovation dilemma
  • Direct Bitcoin settlement: Process transactions directly on the Bitcoin base layer for maximum security when needed using Arch's high threshold signature scheme
  • Pre-confirmation acceleration: Utilize Arch's pre-confirmation system to achieve sub-second responsiveness, overcoming Bitcoin's inherent 10-minute block times
• Sub-second execution with native Bitcoin settlement: Deliver responsive, instantaneous experiences without sacrificing Bitcoin's security guarantees

This flexibility empowers developers to build applications that are both responsive and secure, without sacrificing either quality. Through Arch's UTXO-aware execution environment based on the eBPF virtual machine with custom syscalls, developers can finally implement complex financial applications interoperably with Bitcoin.

Integrated Financial Product Suite

Arch doesn't provide tools for others to build financial products — Arch builds them. The product suite is vertically integrated by design:

• Arch Swap provides native BTC trading with atomic settlement, deep liquidity, and execution guarantees
• Arch Lend enables institutional-grade Bitcoin-backed lending with 300ms liquidation fidelity
• Arch Prime delivers real-time portfolio management — positions, collateral health, yield tracking, and risk exposure in a single dashboard
• Yield Vaults deploy capital across lending markets and structured strategies to generate yield on Bitcoin

This vertical integration is the structural advantage. Closed-loop liquidity between trading and lending enables the liquidation precision that makes scaled credit possible.

Institutional-Grade Risk Infrastructure

• 300ms block finality for deterministic liquidation — positions are enforced before market conditions can move against them
• UTXO-aware execution ensures collateral state is always consistent with Bitcoin's base layer
• Native settlement eliminates bridge risk — collateral is never held in intermediate custody
• High-throughput execution (~1,000 TPS) supports institutional-scale trading and lending volumes
