Flashnet, a decentralized exchange, has introduced native Bitcoin to USDB swaps on its platform. Built on the Spark layer-2 network and powered by USDB, a Brale-issued stablecoin, this new feature allows for fast, low-fee, and trustless trading of BTC against a US dollar-pegged asset directly on the Bitcoin network.

Brale, a platform specializing in Stablecoin-as-a-Service, issued USDB as the first regulated stablecoin on Spark. This integration allows users to hold and trade dollars directly on Bitcoin without intermediaries. Brale's model supports rapid deployment of stablecoins across EVM and non-EVM chains, with day-one integrations for ecosystems like rollups. Their partnership with projects like Glo Dollar demonstrates how they enable compliant issuance in weeks, focusing on community impact over market cap.

During a presentation on the "Day Zero" podcast, Marcus illustrated Flashnet's technology by executing live trades. Starting with a small amount of BTC (equivalent to $10), he swapped it for USDB in under four seconds, incurring just 20 basis points (bps) in fees—no slippage, no middlemen, and fully on-chain. Reversing the trade from USDB back to BTC was even faster, with only 2 bps in costs.

Flashnet aims to significantly reduce trading costs, with execution fees of 2-20 basis points, a substantial discount compared to the 70+ bps typically charged by centralized exchanges.
