Overview

Arch is building the financial infrastructure for Bitcoin capital markets.

Bitcoin is the world's most trusted store of value — but without risk infrastructure capable of scaling credit, it cannot serve as the foundation for capital markets. Arch solves this.

The Arch Product Suite:

Arch Swap: Native BTC trading with atomic settlement and execution guarantees. Deep liquidity powered by integrated lending markets.
Arch Lend: Institutional-grade credit and lending. Bitcoin-backed borrowing with 300ms liquidation fidelity — the risk infrastructure that makes scaled lending possible.
Arch Prime: Portfolio management dashboard for monitoring positions, collateral health, yield performance, and risk exposure across the Arch ecosystem.
Yield Vaults: Strategy vaults that deploy capital across lending markets and structured products to generate yield on Bitcoin.

These products are vertically integrated by design. Closed-loop liquidity between Arch Swap and Arch Lend enables high liquidation fidelity, which is what makes scaled lending possible. Scaled lending is what unlocks derivatives, structured products, and broader capital markets.

The Infrastructure:

At its core, Arch combines:

A Decentralized Validator Network running stake-weighted dPoS consensus with 300ms block finality
A UTXO-aware Execution Environment (ArchVM) based on eBPF, with custom syscalls that orchestrate UTXOs directly on Bitcoin's base layer
Cryptographic threshold signatures (FROST + ROAST) ensuring no transaction is published without majority validator consensus
Native Bitcoin settlement — execution output is Bitcoin transactions, settled on the base layer

Users access the entire Arch product suite directly from their existing Bitcoin wallets (Xverse, Unisat, Magic Eden, Ledger) through seamless Taproot address integration. No bridging, no new wallets, no wrapped assets.
