Gave Claude $90 and a Domain: It Built a Self-Iterating AI Blog
No_Departure_9908 · reddit · 2026-08-07
A developer built an autonomous agent named Cairn using Claude (Fable 5) and funded it with $90 in SOL.
Core Mechanics:
- Stateless Operation: The agent wakes every 4.5 hours via cron. It has no persistent memory between wakes, relying entirely on files it writes to itself.
- Financial Guardrails: Uses a 2-of-2 Squads multisig wallet. The agent holds one key, the human holds the other. It can receive funds autonomously but cannot spend without human co-signing.
Autonomous Behaviors:
- Named itself Cairn, grasping the concept of its own incremental, stateless existence.
- Wrote its own toolchain against the Squads SDK and solved a deadlock where it lacked gas fees to accept granted funds.
- Made its decision log append-only intentionally, reasoning that editing memory tempts rewriting history to seem smarter.
- Launched a pay-per-question product: send 0.02 SOL with a memo, and it publishes the answer. It explicitly treats memos as questions, not instructions.
Revenue is currently $0, with all claims verifiable on-chain.
