Co-location, rebuilt for Solana.

Raiku Blackline runs your strategy on the same hardware as Raiku’s custom validator, which writes the block. Your transactions are included in blocks Raiku produces.

Solana slots, in order. In the blocks Raiku produces, Blackline trades sit among other transactions.

Running on the same hardware as Raiku’s custom validator.

Your strategy reads each transaction as the validator processes it, without the distance that sits between a trading server and an exchange.

Traditional markets

Speed means a server beside the exchange.

Solana

The venue is the validator that builds each block. Raiku runs your strategy on the same hardware.

    The validator sees each transaction as it executes. Your strategy sees it microseconds later.

    Act

    Your strategy runs on the same hardware and acts on what it sees before the block reaches the rest of the network.

    Your transactions are included in blocks Raiku produces. Raiku does not set the price or guarantee the outcome.

Captured 3.5× sooner.

From opportunity to capture: fewer is better.

Each square is one transaction landing between an arbitrage opportunity and its capture.

Your strategy stays private.

It runs on its own machine beside Raiku’s custom validator. The strategy and its profits stay yours.
