Most Layer 1 blockchains treat validators like glorified referees—they confirm transactions, secure the network, collect fees, and that’s about it. Hotstuff Labs is trying something different with Hotstuff L1, a new DeFi-focused chain where validators don’t just validate blocks, they act as financial service providers connecting users to fiat on-ramps, payment rails, and real-world settlement.
The public testnet just went live, and the pitch is ambitious. Hotstuff wants to build what they’re calling an “Uber-style routing layer” where validators compete to deliver financial services on demand. Think less Ethereum, more infrastructure layer that ties on-chain trading directly to global banking systems.

What Makes This Different
Hotstuff L1 runs on DracoBFT, a custom consensus protocol the team built specifically for this use case. The chain itself is designed around a high-performance on-chain order book paired with what they call a “programmable finance routing layer.” That’s a fancy way of saying the chain matches users with validators who can provide specific financial services—fiat on-ramps, remittances, card issuance, currency exchanges, whatever you need.
Instead of treating validators as passive infrastructure, Hotstuff lets them opt into becoming permissioned financial service providers. For traders, validators can tap into off-chain liquidity through stablecoin rails. For regular users, validators handle last-mile connectivity—getting money in and out of crypto, processing payments, supporting local currencies. The chain uses lightweight zero-knowledge proofs to verify both on-chain and off-chain actions without requiring blind trust.
It’s an interesting model, though it does introduce some centralization risk. Permissioned validators aren’t exactly the decentralization purist’s dream, but Hotstuff seems to be prioritizing real-world utility over ideological purity.
The Routing Mechanism
The core idea here is that Hotstuff matches users to validators based on stake, performance history, and quality of service. Need to off-ramp in Brazil? The chain routes you to a validator with strong LATAM payment integrations. Want to issue cards in Europe? Different validator. It’s supposed to work like how Uber routes you to the closest driver, except the “drivers” are validators providing financial services.
Vyom Sharma, Hotstuff’s co-founder and CEO, puts it bluntly: “Most chains validate blocks. Hotstuff validates and delivers trustless access to money.” Whether that actually works at scale is the big question. Routing layers sound great until you hit regulatory walls, liquidity fragmentation, or validators who can’t deliver what they promised.
Who’s Backing This
Hotstuff Labs pulled in backing from some serious names—Delphi Digital, Dialectic, Stake Capital, Tykhe Ventures, and founders from protocols like 1inch, Safe, Biconomy, and Socket. Julien Bouteloup from Stake Capital Group mentioned that the vision aligns with where infrastructure is headed: “decentralized, compliant, and directly plugged into the global economy.”
That’s the tricky part. Building something decentralized that’s also compliant and plugged into legacy finance means navigating a minefield of regulations across different jurisdictions. Every validator offering fiat services is going to need licenses, KYC compliance, banking partnerships—all the things that make DeFi people nervous.
What’s Available Now
The public testnet is open to traders, quants, builders, fintechs, stablecoin providers, and node operators. Traders can test perps and spot trading on the chain’s native order book. Builders and payment companies can explore integrations for trading primitives, payments, FX, and settlement. Validators can run DracoBFT nodes and experiment with the financial service modules.
It’s still early, obviously. Testnets are where things break spectacularly before anyone risks real money. But if Hotstuff can pull off what they’re describing—a chain where validators genuinely act as global financial access points without everything collapsing into regulatory chaos—it would be a legitimate step toward bridging DeFi and traditional finance. Big if, though.
