Raiku Protocol

Raiku is an off-chain transaction scheduler for Solana. It sits between users and validators, maintains a view of upcoming leaders, and routes transactions to the right node at the right slot.

What I built

• The scheduler node: receives transactions, applies routing/verification/dedup policies, and delivers them to validator-adjacent sidecars via private links
• Leader-aware routing against a modified Agave validator that exposes internal leader schedules
• Slot-timed delivery that holds requests until the target slot, cutting spam and improving landing rates
• Observability tooling and operator dashboards (Grafana)
