Boltz is a non-custodial bridge natively connecting Bitcoin, its Layer-2 networks, and stablecoins.
Infrastructure
We enable BTC ↔ stablecoin swaps across onchain Bitcoin, Lightning, Liquid, Rootstock, Arkade, and major stablecoin networks like Ethereum, Polygon, and Solana. Users maintain complete control of their funds via atomic swaps - no accounts or intermediaries required. Our battle-tested APIs and SDKs empower developers to integrate instant, non-custodial BTC ↔ stablecoin flows effortlessly.
Integrations
Boltz is designed for wallet providers adding Lightning or stablecoin features, fintechs seeking non-custodial settlement, and Bitcoin-first businesses bridging to EVM ecosystems. We provide the permissionless swap rails that protocols and liquidity networks rely on.
Sovereignty
While most cross-chain bridges rely on trusted custodians, centralized exchanges, or vulnerable multi-sig setups, Boltz never takes custody of user funds. We provide a production-grade alternative that unlocks global, instant access to Lightning and stablecoins while preserving financial sovereignty.
History
Live since early 2019, Boltz pioneered user-friendly atomic swaps. Today, our infrastructure is integrated into applications like Aqua Wallet, Bull Bitcoin Wallet, and Blockstream App.
EVM SDKs and wallets increasingly need to offer Bitcoin routes but adding Bitcoin - especially its most prominent Layer-2 for payments, the Lightning Network - typically means integrating custodial rails. Boltz BTC ↔ stablecoin swaps instead let users retain full custody of their funds end-to-end.
Businesses accepting cryptocurrency often opt to only accept stablecoins to stay within their unit of account. With Boltz's SDKs and POS solutions, merchants can easily accept Bitcoin while still settling atomically in stablecoins.
