Raiku: A new Solana infrastructure to prevent transaction failures

Brief Overview

According to official documentation, Raiku is an enterprise-grade deterministic layer for Solana infrastructure, enabling businesses to build and operate on-chain with unprecedented speed, higher reliability, and greater efficiency.

Currently, in the crypto world, speed and stability are often a trade-off — you can either pursue fast transactions or sacrifice stability.

Solana is known for its ultra-high throughput and low fees, but as its ecosystem continues to grow, network congestion, transaction failures, or delays during peak times can still occur. This poses a challenge for high-determinism and low-latency applications like DeFi, NFTs, and quantitative trading.

The emergence of Raiku aims to address this pain point.

1. What is Raiku?

<1.1> What is Raiku?

Raiku is a high-performance infrastructure layer built on the Solana network, focused on providing “Enterprise-Grade Certainty” for transactions.

In simple terms, it ensures transactions are “on time and reliably executed,” no longer slowed down by network congestion or performance fluctuations, allowing your transactions on Solana to “no longer fail” and operate in a more controlled manner.

If Solana is a high-speed highway, then Raiku is the smart traffic control system with lane reservations and precise scheduling for that highway.

<1.2> Basic Information about Raiku:

Raiku is a coordination layer that enhances Solana’s core by enabling seamless collaboration between applications, operators, and L1. This improves overall network performance, reliability, and scalable throughput.

By decoupling block construction processes, Raiku empowers block builders to focus on specific areas and offer differentiated features, creating new validator revenue opportunities and richer application experiences. At the same time, transparent transaction ordering mechanisms enhance fairness and coordinate network incentives.

Raiku has secured approximately $13.5 million USD in funding led by Pantera Capital, and is collaborating with validators such as Figment and Kiln to advance testnet development. The mainnet is expected to launch in 2026.

This high level of attention and strong funding background make Raiku one of the most anticipated infrastructure innovations in the Solana ecosystem.

2. How does Raiku solve transaction uncertainty and which DApps is it suitable for?

<2.1> How does Raiku address transaction uncertainty?

In the traditional Solana network, when market trading volume surges (e.g., popular NFT minting or DeFi liquidations), even transactions with slightly higher fees can fail due to congestion.

Raiku’s solution includes:

<2.1.1> Pre-locking execution rights: Applications can reserve block space in advance, ensuring transactions are executed.

<2.1.2> Deterministic execution: Each transaction is executed in a predefined order, avoiding random failures caused by network congestion.

<2.1.3> Improved developer experience: Developers no longer need complex retry logic for failed transactions, simplifying application architecture.

<2.1.4> High performance and scalability: Raiku’s architecture is compatible with Solana’s native performance, supporting more high-frequency scenarios.

<2.2> Which DApps are more suitable for Raiku?

Raiku’s deterministic transaction mechanism is especially suitable for the following types of Web3 applications:

· High-frequency trading and quantitative strategies: Require millisecond response times and guaranteed execution.

· DeFi liquidations and arbitrage systems: Avoid missing opportunities due to network delays.

· NFT minting platforms: Prevent user transaction failures or lag caused by congestion.

· GameFi / real-time applications: Need to ensure instant effect of player actions in interactive scenarios.

In short, any project with a strong demand for transaction stability can benefit from Raiku’s infrastructure.

3. Core Philosophy of Raiku: Deterministic Execution + Pre-booked Block Space

<3.1> What is the core philosophy of Raiku?

Raiku’s core idea is to enable applications to pre-book block space through mechanisms that ensure smooth on-chain execution within a future time window. This transforms transactions from “luck-based” to “guaranteed,” significantly improving user experience.

Raiku’s innovation lies in turning “block space” from a random, competitive resource into a pre-available service. For example, two mechanisms:

<3.1.1> Ahead-of-Time (AoT): Developers or institutions can lock in block space in advance, scheduling transactions for specific times.

<3.1.2> Just-in-Time (JiT): Insert critical transactions at the moment of block creation for millisecond-level control.

More detailed mechanisms and technical documentation are available in the official Docs:

5. Summary

Raiku’s mission is to eliminate transaction failures. It not only addresses the long-standing congestion issues on Solana but also redefines how developers interact with blockchain.

For Web3 teams aiming to build stable, high-performance applications, Raiku is a key piece of the future puzzle.

For individuals, Raiku is still in early stages. You can participate in its testnet validator programs, developer initiatives, and more. The Raiku Discord also features roles like OG and Chads for engagement.

As its official slogan states:

“Raiku makes Solana inevitable.”

Raiku makes the future of Solana unstoppable.
