Key Takeaways
- Hotstuff Labs launched Hotstuff L1, a DeFi-native Layer 1 blockchain, on December 5, 2025, in Singapore.
- The public testnet opened immediately, inviting traders, fintech builders, and validators to engage with integrated on-chain trading and fiat rails.
- Backed by investors like Delphi Digital and founders from protocols such as 1inch, Hotstuff aims to unify decentralized trading, payments, and settlement globally.
Hotstuff Labs unveiled Hotstuff L1 on December 5, 2025, marking a significant advancement in DeFi infrastructure from its Singapore base. This purpose-built Layer 1 blockchain employs the DracoBFT consensus protocol to combine a high-performance on-chain order book with a programmable routing layer, bridging decentralized trading with global fiat payment systems. The project positions itself as an Uber-style routing network where validators serve simultaneously as consensus nodes and essential financial access points.
DeFi-Native Blockchain Designed for Real-World Financial Connectivity
Differing from general-purpose blockchains, Hotstuff L1 offers a specialized routing fabric enabling real-time, trustless connections between on-chain trading and off-chain fiat services. Validators can opt into permissioned financial roles, facilitating fiat-crypto on/off-ramps, payments, foreign exchange, and regional remittance networks. Julien Bouteloup, Founder of Stake Capital Group and an investor in Hotstuff Labs, emphasized the platform’s vision to integrate trading, payment, and settlement in one compliant decentralized layer.
This modular setup allows validators to tap multiple revenue streams by supporting stablecoin rails, issuing local payment cards, and connecting users to diverse currency corridors. Deep integrations with payment platforms, banking partners, and card programs are core to the chain’s architecture, ensuring seamless financial flows that reflect global economic activity.
Public Testnet Launches, Encouraging Broad Ecosystem Participation
The Hotstuff L1 public testnet is now accessible to traders, quantitative analysts, fintech developers, stablecoin providers, and node operators. Participants can test features such as early perpetual and spot markets, multi-venue vaults, and financial infrastructure embedded directly at Layer 1. Validators deploying DracoBFT nodes can benchmark system performance and experiment with finance-specific modules catering to payments, FX, and settlement.

Vyom Sharma, Co-Founder and CEO of Hotstuff Labs, noted, “Most chains validate blocks. Hotstuff validates and delivers trustless access to money. It’s the Uber for financial validators.” The network’s routing algorithm matches users to validators based on stake, service quality, and historical performance, harnessing lightweight zero-knowledge proofs for both on-chain and off-chain verification.
Backers and Ecosystem Support
Hotstuff Labs’ diverse investor base includes Delphi Digital, Dialectic, Stake Capital, Tykhe Ventures, and founders of prominent DeFi protocols such as 1inch, Safe, and Biconomy. This coalition signals growing confidence in programmable finance platforms designed to connect decentralized exchanges with real-world fiat economies.
DeFi: Market Outlook
Hotstuff L1’s December 5 launch introduces a new paradigm by merging on-chain DeFi trading with traditional financial rails. The project’s public testnet invites global stakeholders to build and innovate across trading, payment, FX, and settlement domains. By enabling validators to become active financial access nodes, Hotstuff could pave the way for scalable, compliant decentralized finance ecosystems that integrate seamlessly with legacy financial infrastructure.
