Company profile
researched Aug 2026Rialo is a decentralized programmable blockchain network developed by Subzero Labs, a company that emerged from stealth in August 2025. The network is designed so that applications can interact directly with real-world data and off-chain services from within smart contracts, rather than depending on third-party oracles, indexers, bridges and off-chain monitoring services. Advertised capabilities include HTTPS calls and off-chain API integration written directly into contracts, event-driven and reactive transactions, native privacy, sub-second end-to-end latency, identity based on email, SMS or social accounts, and scalability features such as multiple concurrent proposers.
Technically, Rialo combines RISC-V smart contracts with Solana VM compatibility, which the company says allows existing Solana programs to be deployed while adding a broader feature set. The founders frame the project as a rejection of throughput-only benchmarking: their stated thesis is that high TPS alone does not resolve the developer and user friction created by fragmented middleware. The name is described by co-founder Ade Adepoju as an acronym for "Rialo isn't a layer 1," and he declines to categorize it as a layer 1 or layer 2.
The company publishes a body of technical research on its site covering reactive transactions and native automation, supermodularity and blockchain integration, protocol upgrades ("Gauss"), consistency in distributed systems, threshold cryptography and distributed key generation, native privacy, concurrency control, a "stake for service" payment model, agent-economy design, real-world assets, and prediction markets.
Founding story
Subzero Labs was founded by Ade Adepoju (CEO) and Lu Zhang (CTO), both early engineers at Mysten Labs who worked on the Sui network. Adepoju, based in New York City and 30 years old at the time of the 2025 funding announcement, previously worked at AMD, Dell and Netflix before joining Mysten Labs in 2021; he took a career break in early 2024 to study what makes a network successful before linking up with Zhang to start the company. Zhang previously built Diem, Meta's crypto initiative, and large-scale AI/ML infrastructure at Meta and Google.
Business model
Subzero Labs develops and operates the Rialo network as core infrastructure for third-party developers. Sources do not describe how the company charges for the network beyond a described "stake for service" payment concept in its own research writing. Its August 2025 financing was structured as equity plus token warrants, indicating a planned future token, though as of August 2026 no token, ticker or tokenomics had been announced.
Not described in the available sources beyond a company research post proposing a "stake for service" model for paying for network usage.
Traction
Subzero Labs had 20 employees at the time of its August 2025 seed announcement, with staff drawn from Meta, Apple, Amazon, Netflix, Google, TikTok, Citadel, VMware, Solana, EigenLayer, Polkadot, Coinbase and NEAR Protocol. A private devnet was live in August 2025 and a testnet has been described as running since September 2025; by August 2026 a public devnet playground with four live demo applications and a points program were operating. Mainnet is targeted for 2026.
Latest developments
In April 2026 the company published research on reactive transactions, supermodularity, the Gauss protocol-upgrade mechanism, distributed-systems consistency and threshold cryptography, plus blog posts on consumer lending and bringing private credit onchain. On May 7, 2026 it posted that Subzero Labs (Rialo) was featured in a CBOE innovation spotlight. A Rialo Points program was announced on August 21, 2026, awarding 20 points on sign-in and recognizing early ecosystem contributors and existing community roles.
βΈFull profile β market position, technology, go-to-market, geography, history, risks & controversies
Market position
Rialo positions itself as a new base-layer network that its founders decline to classify as a layer 1 or layer 2, competing for developers with existing general-purpose blockchains and with the oracle, indexer and bridge middleware stack it aims to replace. Investors including Pantera Capital and Hashed publicly framed it as a full-stack network for real-world applications with a devnet already demonstrating event-driven execution and native web integrations.
The stated differentiator is embedding capabilities that are normally external β real-world data access, off-chain API calls, automation/monitoring, privacy and identity β directly into the protocol, removing the need for oracles, indexers, bridges and off-chain keeper services, while retaining Solana VM compatibility so existing programs can be deployed.
Technology
Rialo uses RISC-V smart contracts with Solana Virtual Machine compatibility. It provides native web connectivity (HTTPS calls and off-chain API access from within contracts), event-driven and reactive transaction execution, built-in privacy combining verifiable and confidential execution, and identity primitives based on email, SMS or social accounts. Scalability features cited include multiple concurrent proposers, and the company claims sub-second end-to-end latency. Company research also covers threshold cryptography and distributed key generation, concurrency control for parallel execution, consistency models in distributed systems, and a protocol-upgrade mechanism called Gauss.
Go-to-market
Developer-first distribution: a private devnet with an early-access waitlist and onboarding of early development partners from August 2025, followed by a public devnet playground with a test-token faucet and sample applications (Meridian, Guarded Vault, Ermac and Project 1337). Community engagement runs through a Discord with a tiered role system (RialOPS, Rialo Club, Researcher) and an X account, supported by a technical research and blog publishing program. A Rialo Points program launched in August 2026 grants points on sign-in and recognizes early ecosystem contributors.
Developers and teams building internet-scale decentralized applications, explicitly including non-crypto developers. Cited use cases span tokenized real-world assets, prediction markets, AI agents and agent orchestration, credit and consumer lending protocols, global trading platforms and automated trading systems, and enterprise and consumer applications.
Geography
Subzero Labs announced its financing from New York, New York; co-founder and CEO Ade Adepoju lives in New York City.
History
The company operated in stealth before announcing its emergence and a $20 million initial financing round on August 1, 2025; the deal had closed in the first quarter of 2025. A private devnet was live at the time of the announcement, with early development partners being onboarded via a waitlist. The company published "Introducing Rialo: A Blockchain Built for the Real World" on September 25, 2025, and a testnet has been described as running since September 2025. In December 2025 it recapped "Project 1337." By August 2026 the waitlist had closed in favor of a public devnet playground, and a Rialo Points program was announced on August 21, 2026. In May 2026 the company posted that Subzero Labs (Rialo) was featured in a CBOE innovation spotlight.
Risks & controversies
No token, ticker, tokenomics or airdrop has been confirmed, so devnet participation carries no guaranteed reward and devnet RIALO faucet tokens have no market value. Fake Discord servers impersonating the project have circulated, and third parties have solicited payments or wallet connections in the project's name, which the coverage characterizes as scams. A third-party DApp listing page asserts RIALO token trading and a market capitalization figure, which conflicts with the project's own position that no token has been announced. Mainnet has not launched, and the founders' claim that another network is needed faces the objection that many blockchains already exist.
