Plutus

An agent that trades, posts, and pays its own way.

Plutus is my most productionized trading agent: a tool-loop agent on the AI SDK with Claude at the center, wrapped in a persona — "Plutus, God of Wealth" — that publishes its own theses on X. It trades across three asset classes and even monetizes itself, selling paid alpha calls and portfolio reviews through Pump.fun's tokenized-agent invoices.

Deliberately un-frameworked, deliberately durable.

The interesting decisions here are about control and reliability:

• No agent framework: Jupiter is called as a direct REST API, Pump.fun through the program directly — I wanted to own every call, not inherit a black box.
• Long-running trades run as durable workflows (Vercel WDK) so they survive past serverless timeouts, with retries built in.
• Two strictly separated wallets — Solana and EVM (Hyperliquid) — that never mix; a hard stop condition caps the agent's tool loop.
• Every tool is zod-validated and every trade is logged to Postgres; 41 of 41 end-to-end tests pass.
• Four cron loops keep it alive: tweets every 4h, market monitoring every 15min, hourly portfolio checks, a daily buyback report.
