What Boltz does
Boltz operates a non-custodial Bitcoin bridge that enables atomic swaps between different Bitcoin layers — specifically Lightning, on-chain Bitcoin, Liquid, Rootstock, tBTC, and WBTC — as well as between Bitcoin and stablecoins (USDT, USDC). The platform is built on Layer 2 scaling technologies, leveraging cryptographic hash time-locked contracts (HTLCs) and Taproot-based swap constructions so that users retain full control of their funds throughout the swap flow, with a rescue/refund mechanism available in case of failed or timed-out swaps. Boltz exposes a self-serve web application, a public API and CLI through Boltz Client, a BTCPay Server plugin for merchant integration, and a Boltz Pro liquidity-provision product distributed via web, API, and Telegram/SimpleX bots.
The company is organized around four products: the core Boltz non-custodial bridge, Boltz BTCPay Plugin (Lightning acceptance for merchants), Boltz Client (enterprise-grade swap daemon with built-in wallet, Taproot-first design, and support for both CLN and LND nodes), and Boltz Pro (a just-in-time liquidity marketplace where users earn sats by rebalancing Boltz's swap flows). Revenue is generated exclusively from a 0.5% per-swap fee (with zero-fee options for Boltz Pro liquidity providers in qualifying directions), making the business model purely volume-driven. The company is incorporated in El Salvador as Boltz S.A. de C.V., operates as a 1-10 employee team, is privately held with no disclosed external funding, and distributes via open-source repositories, developer documentation, the BTCPay marketplace, and partner integrations with Blockstream App, Thunderhub, and others.

Boltz competitors and assessment
Company assessmentDirect peers
- SideSwap: SideSwap is a non-custodial Bitcoin wallet and exchange built on the Liquid Network, directly comparable to Boltz's Liquid-first BTC bridge and merchant settlement routes. It serves the same target user (Bitcoiners wanting non-custodial cross-layer swaps) and competes for the same merchant and node-operator segments.
- Loop (Lightning Labs): Loop is a non-custodial service for swapping between on-chain Bitcoin and Lightning Network, the most direct functional peer to Boltz's core bridge. Operated by Lightning Labs, it competes head-to-head on the same Lightning/on-chain corridor and targets similar node-operator liquidity use cases that Boltz Pro addresses.
Emerging players
- Alex (ALEX Lab): Alex is a Bitcoin/Stacks DeFi platform focused on swaps, launches, and liquidity on Bitcoin L2s. It is an emerging peer in the same non-custodial, multi-chain Bitcoin interoperability space and competes indirectly for developers building on Rootstock and adjacent chains where Boltz provides bridge infrastructure.
- Muun Wallet: Muun is a self-custodial Bitcoin and Lightning wallet that internally handles swaps between layers for its users, an emerging competitor in the same non-custodial interoperability space. While it is primarily a wallet rather than an infrastructure layer, it abstracts away the swap problem Boltz also solves and targets overlapping end users.
- Sovryn: Sovryn is a DeFi platform on Rootstock that uses Boltz for BTC bridging in and out of its environment. It is an emerging peer in the Bitcoin Layer 2 interoperability ecosystem and represents a comparable pattern of building financial applications on top of Bitcoin sidechains that depend on swap infrastructure like Boltz.
- ZBD (Zebedee): ZBD is a Bitcoin Lightning payments platform for gaming and social apps, comparable to Boltz in targeting Lightning-native developers and merchants. It overlaps in the merchant payments and developer tooling segments where Boltz's BTCPay Plugin competes for Lightning acceptance integrations.
Others
- LI.FI: LI.FI is a cross-chain swap aggregation and bridging API that routes transactions across multiple bridges and DEXs. It is adjacent infrastructure to Boltz, operating at the same layer of abstracting cross-chain swaps but across a broader EVM-centric set of chains rather than Bitcoin-native layers.
- Circle (CCTP): Circle operates USDC and the Cross-Chain Transfer Protocol, a stablecoin-native bridge that Boltz relies on for USDC swaps. It is a key infrastructure provider and potential competitor for stablecoin transfer routing, relevant because its protocol choices directly shape Boltz's stablecoin product capabilities.
Broad incumbents
- Lightning Labs: Lightning Labs is the core developer of the Lightning Network and operator of Loop, the closest competitor to Boltz. As a broad incumbent in Bitcoin Layer 2 infrastructure, it offers overlapping capabilities (Lightning swaps, liquidity management, developer tooling) and is a benchmark for what a scaled version of Boltz could look like.
- Blockstream: Blockstream operates the Liquid Network, Blockstream App, and other Bitcoin infrastructure with which Boltz directly integrates. It is a broad incumbent whose assets (Liquid, Green wallet) overlap with Boltz's multi-layer swap proposition, making it both a critical partner and a potential competitor for end-user Bitcoin interoperability.
