The world’s most widely used stablecoin meets the Lightning Network: non-custodial swaps without intermediaries are now available.
Boltz Exchange has introduced the ability to swap satoshis on the Lightning Network for USDT on Arbitrum-based networks through fully non-custodial atomic swaps.
The innovation is based on the integration of USDT0, Tether’s omnichain version built on LayerZero’s Omnichain Fungible Token (OFT) standard. This solution consolidates all liquidity into a single token, primarily on Arbitrum, eliminating the need for Boltz to build separate liquidity pools across dozens of different blockchains such as Ethereum, Polygon, Optimism, or Rootstock.
For Bitcoin users, this integration provides direct and immediate access to the world’s leading stablecoin without needing to understand the technical complexities of cross-chain bridges. On the other hand, DeFi users gain a direct path to Lightning payments without counterparty risk.
The main advantage lies in eliminating the typical risks of centralized exchanges: no third-party custody of funds, no KYC requirements, and no need to rely on intermediary services.
Atomic swaps ensure trustless and simultaneous execution of trades across different blockchains or layers, preventing situations where one party could receive funds without delivering their side of the exchange.
Boltz’s development roadmap includes extending USDT swaps to all currently supported Bitcoin layers, including on-chain, Liquid, Rootstock, and Arkade. Future updates will also incorporate USDT0’s Legacy Mesh, which is expected to enable direct support for additional chains such as Tron and Solana. According to Tether’s transparency report dated March 17, Tron currently holds the largest USDT supply, with approximately $83.9 billion.
