Raiku

We are proud to announce our $13.5MM raise, led by Pantera Capital, with Jump, Faction VC, Figment Capital, Big Brain Holdings, and more visionary partners. We’re making Solana inevitable with institutional-grade certainty, guaranteed transaction inclusion and advanced scheduling. Solana is built for internet capital markets, but major enterprises won’t come on-chain until transactions are guaranteed to land exactly as expected. Raiku gives businesses the certainty they demand, taking the guesswork out of submitting transactions so they can focus on their users. We’re already live on testnet, and collaborating with many of the top validators on Solana: - MEV protection at the validator level - 60k tps with guaranteed inclusion - Slot reservations up to 60s ahead-of-time, with - <50ms pre-confirmation time This raise provides us the resources we need in order to build a world where EVERY business can operate on-chain with the determinism, speed and reliability their customers require. We’re making Solana the default choice for builders everywhere. We’re making Solana inevitable.

Join Raiku as a Senior Rust Engineer! Build the coordination layer between applications and validators - from guaranteed inclusion mechanisms to bandwidth markets. If you understand that performance and reliability beat ideological purity, we want to talk. Apply here: https://lnkd.in/gxghXU_B

Robinhood's choice of Arbitrum Orbit over Solana for tokenized stocks wasn't about performance: it was about control and compliance. Robinhood needed: - Complete control over transaction ordering (to prevent illegal front-running) - Custom compliance logic for regulatory requirements - Deterministic execution for 24/7 tokenized equities Traditional finance needs predictable infrastructure with guaranteed execution, while most blockchain infrastructure offers probabilistic systems. Arbitrum Orbit delivered this through a private sequencer, but this could have been delivered on Solana too! Link to our latest blog in the first comment

Shoal Research just published an in-depth analysis of how we're solving blockchain's reliability problem through high-performance edge compute infrastructure. The Challenge: While Solana leads on throughput and latency, it still lacks the execution guarantees that high-stakes applications demand. High-frequency traders see failure rates up to 75% during network congestion. Ethereum handles just 15-30 TPS with a decade-long scaling roadmap ahead. Our Approach: Raiku introduces specialized execution infrastructure that makes Solana transactions fast, reliable, and guaranteed. Rather than fragmenting the ecosystem like traditional Layer-2s, our edge compute environments enhance Solana's base layer while preserving unified accounts and composability. Key innovations highlighted in the report: 🔹 Ahead-of-Time Block Auctions - Reserve blockspace and get inclusion guarantees 🔹 Deterministic Execution - Eliminate transaction uncertainty and mempool chaos 🔹 Global Account Model - Unified state across execution environments 🔹 Proof Streaming - Handle large payloads via sequential blockspace reservations The research explores how this infrastructure enables institutional-grade applications: payment networks with 99.999% uptime, high-frequency trading with microsecond precision, hybrid CEX/DEX exchanges, and real-time gaming with deterministic execution. Banks, hedge funds, and payment processors can get the performance and control they require on-chain, without sacrificing decentralization. As Shoal Research notes: "With Raiku, building on Solana can feel like building on a scalable cloud service. Need more throughput? Spin up an extension. Need custom logic? Plug in an edge compute zone. Worried about peak times? Offer guaranteed inclusion."

Why did Robinhood choose Arbitrum over Solana for their $18.9 trillion tokenized asset play? Hint: It wasn't about speed. Earlier this month, Robinhood launched tokenized versions of over 200 U.S. stocks and ETFs for European customers, including major companies like Nvidia, Apple, Microsoft, and even private companies like OpenAI and SpaceX. And they chose Arbitrum to do it. Robinhood needed fine-grained control over transaction sequencing, infrastructure-level customization, and protocol logic: all critical for 24/7 tokenized equities under strict compliance requirements. Three Solana upgrades that could have changed Robinhood's decision: - APE: Consensus ≠ Execution - MCL: Multiple leaders, less MEV - Alpenglow: Sub-150ms finality We explore what that would take to build it on Solana in our latest blog (link in the first comment) 👇

Raiku makes every transaction fast, reliable, and predictable. Built on Solana, our protocol delivers deterministic execution, guaranteed inclusion, and low-latency performance—solving the foundational failures that cause transactions to miss and trades to revert. By placing high-performance compute close to where transactions happen and coordinating execution through our advanced scheduling engine, Raiku gives developers and institutions the reliability and control they demand. We believe financial infrastructure should behave like physics: fast, reliable, and predictable.
