Learn Rialo — technology & products

Rialo is a developer-first Layer 1 blockchain by Subzero Labs, built to give Web3 apps a Web2-like experience — fast, responsive, and connected to the real world. Tagline: 'Rethink. Rebuild. Rialo.'

• Positioned as 'infrastructure for the next generation of intelligent systems' — often called a 'Real World Chain'.
• Makes real-world connectivity native to the protocol, aiming to render oracles, bridges, indexers, and keepers obsolete.
• Targets internet-scale apps: AI agents, prediction markets, and real-time onchain markets.
• Combines Web2-level UX (speed, usability, low cost) with Web3 decentralization and built-in privacy.

Rialo's VM is based on the RISC-V instruction set and is compatible with the Solana VM (SVM), so developers can reuse existing Solana programs. EVM and MoveVM support are planned.

• Rialo VM: RISC-V based, SVM-compatible (EVM & MoveVM soon), and ZK-friendly.
• REX (Rialo Extended Execution Runtime) enables Confidential Computing via TEEs.
• Execution Engine is event-driven with Conditional Transactions and Hybrid Concurrency Control for dynamic real-world workloads.
• Design targets (Dev Portal benchmarks): sub-second finality, very high execution TPS, near-instant reaction time.

Smart contracts on Rialo can talk directly to the internet (HTTPS / Web2 APIs) without external oracles or bridges.

• Native webcalls let contracts fetch live data (prices, weather, feeds) and call external services directly.
• Enables native communication with AI agents, including protocols like Google's Agent2Agent (A2A).
• Removes multi-hop overhead, bridging scripts, and external watchers — fewer trust assumptions, consistent security.
• Can securely store and use credentials (e.g. API keys) without exposing them.

Also called conditional transactions: logic that executes automatically when a predicate becomes true, validated by the chain itself. No bots, keepers, or cron jobs.

• Predicates can be time-based ('every 10 blocks'), value-based ('when balance > $1000'), or data-driven ('when BTC < $95K').
• Supports long-running programs across many blocks — able to suspend, wait, and resume on future conditions.
• A conditional transaction can spawn more conditional transactions, enabling multi-step workflows lasting hours or days.
• Flow: deploy predicate -> chain evaluates each block -> when matched, auto-execute. Trustless, no privileged operators.

Native real-time data feeds for DeFi, RWAs, and more — advertised as over 40x faster than top oracles.

• Sub-100ms latency data with 100k+ tickers/second in Rialo's demos.
• Powers real-time onchain markets with no middleware or oracles.

Identity, privacy, and compliance are first-class native capabilities rather than app-layer add-ons.

• Privacy is native — not outsourced to the application layer.
• Balances privacy with the verifiability needed for compliance.
• Seed-phrase-free identity reduces the key-management burden that causes permanent loss of funds.

Native gasless transactions with low-to-zero fees, so apps can feel free to end users.

• Removes gas friction for everyday users.
• Enables consumer-grade UX for onchain apps.

One account that transacts across multiple networks.

• A single account usable across chains, with easy and safe interoperability.

SCALE = Simple Contracts for Agent Labor Execution. Inspired by the YC SAFE note, it sets simple, enforceable terms for paying AI agents to do work.

• Uses on-chain logic to enforce task deadlines and quality assurance, refunding on late or low-quality delivery.
• Built on Rialo's native webcalls (talk to agents / A2A), native timers (auto-enforce deadlines), and fast payments.
• Addresses the same risk as hiring a human contractor who delivers late or below your quality bar.
• This is exactly the model Trocooony implements: mint -> escrow -> dispatch -> deliver -> judge -> settle.

Trustless guard-rails for autonomous agent execution at scale, plus an open marketplace for agent services (gateways).

• Gateways are services (payments, automation, web access, compute, confidential compute) shipped by third parties.
• Publish a service, meter usage, get paid in RLO, and build reputation from verifiable on-chain outcomes.
• Users can earn by evaluating gateways; gateways can be owned by DAOs.
• Aims at a machine-to-machine economy with billions of autonomous transactions per day.

RLO is Rialo's native token used to pay for gateway usage, agent tasks, and rewards.

• Gateway providers and evaluators earn RLO; reputation is built from verifiable outcomes.

Rialo offers a Rust-based toolkit plus a browser playground and learning resources.

• rialo-cdk (Rust) — the primary library for building Rialo apps.
• rialo-rex-evm — drive transactions on EVM chains from Rialo programs via REX WASM inside a TEE.
• rialo-venus-dsl — the rialo! macro generates Solana program interfaces from high-level workflow definitions.
• Playground (playground.rialo.io), Learn (learn.rialo.io), Docs (rialo.io/docs), Dev Portal (rialo.io/for-devs), GitHub (github.com/rialo).

Subzero Labs raised a $20M seed (Aug 2025) led by Pantera Capital, with a team drawn from top tech and crypto organizations.

• Investors include Pantera Capital, Coinbase, Susquehanna, Edge Capital, Mirana, Mysten Labs, and Hashed.
• Contributors come from Meta, Netflix, Google, Apple, Amazon, Uber, Robinhood, VMware, Solana, Near, EigenLayer, Magic Eden, Parity, Diem, Linera, and MoonPay.
• Featured in the CBOE Innovation Spotlight.

Rialo has shipped real-time onchain proofs of concept on its devnet / Apex Network.

• 'Stonk Crush' / Onchain Bloomberg Terminal: a real-time onchain market terminal tracking 1000+ live tickers, verified and settled natively onchain with sub-second proofs and zero oracles.
