Boltz Exchange has introduced atomic, non-custodial swaps for USDT, specifically designed for Lightning Network users. According to NS3.AI, this new feature allows users to exchange Lightning sats and USDT on Arbitrum-based networks via USDT0. The process is streamlined by routing through tBTC on Arbitrum, integrating Bitcoin and decentralized exchange steps into a single router transaction. Additionally, gas abstraction eliminates the necessity of holding ETH on Arbitrum. Boltz has announced plans to extend this service to additional Bitcoin layers and intends to incorporate direct chain support for networks such as Tron and Solana through USDT0's Legacy Mesh.
