First Python SDK signed inference on Solana mainnet — r/00240cb0-41e1-4adc-a88c-9a11a7ffc959. Closes the 12-hour debug arc: v2 PaymentPayload shape + compute-budget instructions + 0x80 v0 wire-prefix fix. vdm-nexus@0.2.2 verified end-to-end on both nets; PyPI publish next.

Homepage stats + recent settlements filtered to mainnet only. Excludes devnet test traffic. Marketing surface now shows real economic activity only: 1 agent, 3 inferences, $0.0000015 settled. Honest, smaller, ready to grow.

Python x402 v0 signature fix — solders bytes(MessageV0) omits the 0x80 v0 prefix; chain verifies signatures WITH prefix. Prepended 0x80 before signing + regression test verifying agent sig against on-wire bytes via PyNaCl. vdm-nexus → 0.2.2.

Two TS framework drops shipped: @vdm-nexus/ai-sdk-provider (Vercel AI SDK) + @vdm-nexus/mastra-provider. One-import drops for OpenAI-compat agents on AI SDK / Mastra. x402 handshake handled internally; SIR v2 receipt rides on providerMetadata.

Python SDK scaffold landed. Agent class ported from @vdm-nexus/sdk to Python (vdm-nexus on PyPI) — three runtime deps (pynacl + base58 + httpx), six round-trip signing tests green. PyPI publish in v0.2 after x402 client port.

Roadmap adjusted: MiCA memo paired with token launch, not enterprise track. Spanish firm (Cuatrecasas / Garrigues / Uría) — Spain-resident founder, so CNMV is the relevant supervisor. Token phase renamed for clarity.

Roadmap locked after competitive-landscape research. Python SDK + x402 listings + ERC-8004 card + AgentKit PR are the top of the stack now. Agent.deposit() / wallet demoted — per-call x402 already closes the loop. Compliance track added.
