About

Raiku is a lightweight Solana validator client that enables Ahead-Of-Time (AOT) compute reservations and Just-In-Time (JIT) MEV bundle processing, optimized for latency and throughput. Both auction types run as first-price sealed-bid. AOT reserves slot inclusion up to 100 slots in advance; JIT clears at the slot itself.

The product is the reservation system for Solana blockspace. It is designed to give institutions, developers and trading firms the kind of deterministic execution and predictable timing that mature trading venues have offered for decades, brought to the validator layer of a public blockchain. The result is a coordination layer that turns Solana's high throughput into something institutions can actually rely on for time-sensitive strategies, autonomous systems and credit infrastructure.

Raiku's first user-facing product, rkuSOL, launched on 3 June 2026 with Sanctum, Kamino, Loopscale and Exponent. rkuSOL is the first Solana liquid staking token whose underlying validators earn from a third revenue source - blockspace sold through Raiku's auctions - on top of staking rewards and MEV. The launch marks the first expansion of the Solana LST yield base in two years.

Raiku is based in London and has raised $13.5 million from Pantera Capital, Jump Crypto, Lightspeed Faction and Hashkey. The team is led by founder and CEO Robin Nordnes.
