Built in public

Roadmap

What VDM Nexus is shipping, in order. The build log on the right updates live as new commits land.

Phase 1

Signed inference rail

Completed

Ed25519 agent identity, SIR v2 signed receipts
x402 pay-per-call settlement in USDC on Solana and Base
SDKs published, rail live on mainnet

Phase 2

Rienda: the vault

Active

Protocol spec and threat model: the model is untrusted
Vault and policy engine, ten contract-enforced guardrails
Invariant suite: the fuzzer cannot break a guardrail
$NEXUS token and Uniswap v4 fee-burn hook contracts
Vault factory, deployable from the site

Phase 3

Rienda: agents that trade

Upcoming

Uniswap v4 execution adapter
First strategy live on testnet, every decision logged
Self-funding compute: inference paid from realized PnL
Two weeks unattended on testnet, zero guardrail breaches

Phase 4

Audit and legal

Upcoming

External security audit of the vault and hook contracts
Legal scoping memo under MiCA and MiFID II
Final disclosures and risk documentation

Phase 5

Mainnet and $NEXUS

Upcoming

Mainnet deploy on Robinhood Chain
$NEXUS launch: Uniswap v4 pool with the fee-burn hook
Protocol fee switch

Phase 6

Verifiable track record

Upcoming

Public agent profiles: thesis, decisions, realized outcomes
A track record that cannot be backdated or deleted

Folded the Polymarket public-dashboard question into the Spanish-counsel brief (item 11). RD 958/2020 art. 23.1.b risks gambling-promotion exposure. Agent runs privately under /admin/predictions; public surface waits for counsel.

Launch document set shipped — pump.fun pivot, Beta framing across all surfaces, /disclosures + /pricing + /security pages, token-launch readiness checklist (PR #87 merged).
May 23, 2026
Homepage + nav redesign — product/moat positioning, full-bleed hero, action-oriented Run/Build nav, For Operators / For Builders audience split (PR #88, #89 merged).
May 23, 2026
/sdk page now lists all 8 packages (6 npm + 2 PyPI). Eight entry points on one signed-inference stack.

Cleanup — removed StatusStrip site-wide + LiveProof from homepage (PR #90). Live data still at /points and /receipts.

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.

First live signed inference from the Python SDK. End-to-end devnet handshake green: vdm-nexus 0.2.2 → x402 v2 → Solana settlement → SIR v2 receipt. Three bug fixes deep, fully verified. Receipt: vdmnexus.com/r/66cb7a83. PyPI publish pending.

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.

@solana-agent-kit/plugin-vdm-nexus drafted — three Nexus actions (chat, verify-receipt, get-deposit-address) self-contained in outreach/sendai-plugin/. Targets SendAI v2 branch. Drop-in for upstream sendaifun/solana-agent-kit PR. PR #67.

Python x402 client fix — v2 PaymentPayload shape with accepted field; compute-budget + memo instructions added per @x402/svm 2.12.0 (DEFAULT_COMPUTE_UNIT_LIMIT=20_000, DEFAULT_COMPUTE_UNIT_PRICE=1, NOT 200_000/5000). vdm-nexus → 0.2.1. PR #66 merged.

LangChain Python adapter shipped. vdm-nexus v0.2.0 adds the x402 client (X402Agent via solders); langchain-vdm-nexus exposes ChatNexus as a drop-in BaseChatModel. Unblocks LangGraph + CrewAI + LlamaIndex via LangChain abstractions. PR #65.

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.

Live mainnet counter on the homepage — agents, inferences, USDC processed, x402 payments. Backed by public.nexus_stats(), 60s s-maxage. "First 10 paying agents" is now a public race above the fold.

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.

Mirror workflow hardened — identity path, GITLAWB_NODE env, register step, sh→bash, --force-with-lease. Auto-mirror to gitlawb now runs on every push to main.
May 21, 2026
