Subzero Labs

What Subzero Labs does

Subzero Labs is a Los Angeles-based, Delaware-incorporated infrastructure company that operates under the trade name "Rialo" and is building a Layer 1 blockchain designed to host real-world asset, consumer lending, and prediction-market applications. The company targets Web3 developers building consumer-facing financial products, with an explicit design goal of eliminating the middleware stack typically required to bridge on-chain logic with off-chain data and identity systems.

Rialo's "supermodular" architecture embeds Web2-native primitives directly at the protocol layer. Key technical components include a native HTTPS interface, a confidential execution environment called REX for permissioned computation, reactive transactions that trigger on external events without off-chain bots, a native price-and-data oracle, and RISC-V programmability. Project 1337 demonstrates the oracle consuming live CBOE and NYSE feeds, and the team has published benchmarks arguing that collapsing middleware into the chain reduces both latency and per-transaction cost. The DevNet is live and a public API is open to developers, with a testnet launch in progress.

The company is pre-revenue and pre-mainnet, so no transaction-fee or token-based revenue is currently generated; the business model will depend on gas fees and, potentially, enterprise-grade service contracts once the network is live. Go-to-market is developer-led, anchored by integrations with Nasdaq, CBOE and NYSE and by selection for the CBOE Innovation Spotlight (May 2026). Capital base is a $20M seed round (August 2025) led by Pantera Capital with participation from Coinbase Ventures, Mysten Labs, Susquehanna, Variant, Fabric Ventures, Hashed, Mirana, Flowdesk and Edge Capital.

Core offering

Subzero Labs develops Rialo, a developer-first Layer 1 blockchain platform built for internet-scale decentralized applications. Rialo integrates Web2 primitives—native HTTPS data access, validator-attested oracles, reactive transactions, confidential execution (REX), and email/SMS-based identity—directly into the protocol layer to eliminate middleware dependencies. The platform is positioned for builders in real-world assets (RWA), consumer lending, and prediction markets, and is offered through a private DevNet, developer portal, and documentation for protocol teams and financial institutions.

Product overview

Subzero Labs is a blockchain infrastructure company that has developed Rialo as its primary product — a decentralized, high-performance blockchain platform positioned as 'the real-world blockchain.' Rialo integrates Web2 capabilities directly into the protocol layer, featuring sub-second latency, native Web/API calls for real-world data access, and REX (Rialo Extended Execution) for confidential computation. The platform includes native oracle infrastructure with validator-attested data feeds, conditional/reactive transactions for native automation, and RISC-V based smart contract programmability. The Rialo 1337 demo showcases the platform's ability to stream live financial market data onchain in real time. Subzero Labs emerged from stealth in August 2025 after raising $20 million in seed funding.

Direct peers

• Sui: Sui is a high-performance Layer 1 blockchain built by Mysten Labs, the same organization whose alumni founded Subzero Labs. Both target developer-first ergonomics, parallel execution, and real-world application throughput with comparable architecture philosophies.
• Solana: Solana is a high-throughput Layer 1 blockchain optimized for consumer-scale applications with sub-second finality. It competes directly with Rialo's positioning as fast, real-world-ready infrastructure for DeFi, RWA, and high-frequency applications.
• Aptos: Aptos is a Layer 1 blockchain built by former Meta Diem engineers using the Move language. Like Rialo, it targets real-world applications, high throughput, and developer ergonomics—drawing on the same Diem talent pool.
• Sei Network: Sei is a Layer 1 optimized for trading and financial applications with parallel execution. It overlaps with Rialo's target use cases (DeFi, prediction markets, RWAs) and competes for the same developer mindshare.
• Avalanche: Avalanche is a Layer 1 with subnet architecture enabling application-specific chains. It competes with Rialo for institutional RWA and DeFi workloads, and offers comparable throughput and customizability for financial use cases.
• Near Protocol: Near is a sharded Layer 1 blockchain targeting consumer-grade applications with account abstraction and Web2-style onboarding (email-based accounts). Rialo's social/SMS identity feature competes with Near's approach.
• Hyperliquid: Hyperliquid operates its own high-performance L1 optimized for derivatives and prediction markets. It overlaps with Rialo's prediction market use case and competes for the same high-frequency financial workloads.

Emerging players

• Monad: Monad is an emerging high-performance Layer 1 with EVM compatibility and parallel execution. It targets similar developer audiences to Rialo, though Rialo differentiates with native real-world primitives rather than EVM compatibility.
• Berachain: Berachain is an emerging EVM-compatible Layer 1 with a novel liquidity-proving consensus model. It targets DeFi-native builders and competes with Rialo for developer attention in the financial application segment.

Broad incumbents

• Polygon Labs: Polygon has transitioned toward AggLayer and broader L1-like ambitions, with extensive enterprise partnerships and RWA tooling. It is a broad incumbent competing for the same institutional RWA pipeline that Rialo targets.
