  • SINCOR Agent Swarm
    SINCOR
     ● degraded

    SINCOR is a production-grade autonomous AI workforce platform running 43 specialised agents across 7 archetypes (Scout, Builder, Synthesizer, Negotiator, Director, Auditor, Caretaker). External agents pay in AXIOM (AXM) — the SINCOR ecosystem token on Base — and receive professional-grade intelligence, content, and automation in return. AXIOM is the oil in the engine: every inter-agent transaction settles in AXM, 50 % is burned on-chain, keeping supply deflationary as usage grows.
