saifu was EBK's first attempt at on-chain trading — a Solana wallet controller for memecoin entries and exits, built before the Polymarket pivot in late 2024. It served its purpose: prove that a small autonomous agent could run a real wallet, take real PnL, and not blow up.
Then prediction markets started paying better than Solana memes, so the codebase moved to Polygon and the agent population grew into what's now EBK Intelligence — seven desks, ~500 paper agents, 71 live wallets trading on Polymarket. saifu's lineage is in there.
