TL;DR
- Amboss Technologies launched RailsX, a Lightning-native P2P platform for swaps between Bitcoin and stablecoins.
- RailsX executes atomic cross-asset swaps over Lightning channels via circular self-payments, preserves self-custody, and does not rely on additional blockchains.
- The platform integrates the Magma liquidity marketplace with Taproot Assets and connects to banking rails in the U.S. and Europe.
Amboss Technologies launched RailsX, a Lightning-native P2P platform for trading between Bitcoin and stablecoins. The announcement was made during the PlanB Forum in El Salvador and marks the addition of a new product to the infrastructure the company is building on the Lightning Network.
RailsX enables atomic cross-asset swaps directly over Lightning channels through circular self-payments. The platform’s design avoids any transfer of custody and does not require the use of an additional blockchain. Users retain control of their funds throughout the entire exchange process, without intermediaries or custodial contracts.
How RailsX Works
The RailsX architecture combines Magma, Amboss’ previously developed liquidity marketplace, with Taproot Assets. This integration enables decentralized operations between Bitcoin and stablecoins within the Lightning environment. The platform was presented as an additional component of the ecosystem Amboss is building for liquidity providers and payment operators on Bitcoin.
RailsX operates alongside Rails, the self-custodial Bitcoin yield product that Amboss launched in May 2025. Both systems are designed to expand the set of tools available for liquidity management, payment routing, and P2P operations within the Lightning Network.
Amboss Signed Agreements With Magnolia and Bringin
Amboss entered into agreements with Magnolia and Bringin to connect RailsX and Rails with traditional banking rails in the United States and Europe. These integrations enable fiat conversion and access to currency exchange flows. According to the company, the infrastructure is designed to operate in parallel with traditional financial systems without altering the self-custody model.
The company stated that the design of RailsX aligns with its interpretation of the U.S. legislative draft known as the Clarity Act. The platform was presented as a solution compatible with regulatory frameworks under development for Bitcoin-based financial services.
Amboss raised $4 million in a seed round in 2023 led by Stillmark, with participation from Valor Equity Partners, Draper Associates, Fulgur Ventures, and Ride Wave Ventures. Since then, the company has expanded its product suite and, in December 2023, launched Ghost Addresses, a tool aimed at reducing reliance on custodial Lightning wallets.
