Oprai

AI Platforms / Agents

Oprai is a platform that allows users to perform all transactions on the Solana blockchain simply by talking to an AI. From Jupiter to pump.fun and on to Magic Eden, users can interact with dozens of platforms directly through the AI.

Oprai serves as the AI layer for Solana.

Opsonchain

DeFi

Opsonchain is Solana's first volume-weighted average pricing execution infrastructure built using Jito Bam with application-controlled execution capabilities.   We replace blind DCA execution with a signal-gated, deterministic engine that reads pool depth, spread, and momentum, firing only when the market can absorb the order.   Built for DAOs, treasuries, and institutions executing large on-chain orders.

OrbLocker

Orin

AI Platforms / Agents
