Amboss, a company renowned for developing tools and infrastructure for the Bitcoin Lightning Network, has launched RailsX, a new peer-to-peer exchange that enables users to directly trade bitcoin and stablecoins with one another. This platform comes without the need for centralized exchanges, allowing users to retain control over their funds. The announcement was made during the PlanB Forum in El Salvador.
RailsX aims to address a significant challenge faced by many Bitcoin users: the difficulties encountered when converting between bitcoin, dollars, and other currencies. Traditionally, this process has depended on centralized platforms susceptible to account freezes, high fees, and geographic restrictions. In contrast, RailsX harnesses the Bitcoin Lightning Network, facilitating direct trades while keeping user funds secure.
Unlike conventional cryptocurrency exchanges, RailsX does not manage customer assets or maintain a traditional order book. Instead, it facilitates peer-to-peer swaps through Lightning payment channels, allowing instant and cost-effective exchanges between bitcoin and Lightning-based stablecoins.
The platform supports stablecoins created on Bitcoin using Taproot Assets, a new protocol that enables the creation and transfer of dollar-pegged tokens over the Lightning Network. This innovative approach allows users to convert between bitcoin and stablecoins without relying on other blockchains, ensuring a seamless experience within Bitcoin’s ecosystem.
The implications of this new offering could be substantial, particularly in the context of the global foreign exchange market, which sees approximately $9.5 trillion in transactions daily. Currently, access to this market is mostly restricted to banks, brokers, and large financial institutions. Amboss posits that Lightning-based stablecoins and peer-to-peer trading could democratize currency exchange, making it accessible to anyone with an internet connection, a Lightning wallet, and self-custodied funds.
RailsX is an extension of Amboss’s existing product, Rails, which allows users to provide liquidity to Lightning channels and earn fees while maintaining control over their bitcoin or stablecoins. Together, these products aspire to create a more liquid Lightning ecosystem, facilitating efficient routing for payments and trades across the network.
To enhance the integration of Bitcoin with traditional finance, Amboss is collaborating with companies like Magnolia and Bringin to establish fiat on- and off-ramps in the U.S. and Europe. This partnership aims to enable users to convert between fiat currency and Lightning-based assets without resorting to centralized crypto exchanges.
The launch of RailsX comes at a time when there is renewed enthusiasm for incorporating stablecoins on the Bitcoin network. Key figures in the industry, including Tether CEO Paolo Ardoino and Lightning Labs CEO Elizabeth Stark, have recently expressed support for the issuance of USDT and other stablecoins natively on Bitcoin via Taproot Assets.
Amboss CEO Jesse Shrader remarked that RailsX represents a pivotal step in Bitcoin’s evolution, positioning the product as a means to expand Bitcoin’s utility beyond mere speculation and facilitate everyday financial activities.
