Catenaa, Friday, December 12, 2025- Hotstuff Labs has launched the public testnet for Hotstuff L1, a DeFi Layer 1 blockchain that connects on-chain trading with global fiat rails using its custom DracoBFT consensus protocol.
The platform combines a high-performance on-chain order book with a programmable finance routing layer.
Validators can participate as permissioned financial service providers, enabling stablecoin rails, cross-border payments, remittances, card issuance, and multi-currency settlements.
Users are matched to validators based on stake, performance, and service quality, with zero-knowledge proofs ensuring trustless verification of on- and off-chain operations.
Traders, quants, fintechs, stablecoin infrastructure providers, and node operators can access the testnet to experiment with trading, payments, FX, and settlement solutions.
Hotstuff Labs said the system aims to create a coherent settlement network connecting regions from Asia to LATAM and Europe.
The project is backed by Delphi Digital, Dialectic, Stake Capital, Tykhe Ventures, and founders of 1inch, Safe, Biconomy, and Socket.
Hotstuff Labs intends to provide a modular, programmable financial layer integrating trading, payments, and settlement, while giving validators opportunities to generate revenue.
Hotstuff L1 represents a shift in blockchain design, merging consensus, financial services, and real-world settlement into a single decentralized infrastructure for global DeFi and fiat access.
