EVIDIQ Helm

Compass prices the market.

Helm proves how it traded.

Every other hackathon entry will publish a PnL number. Helm publishes a number with evidence behind it: which signal fired, which rule matched, what stop was set, at what price — signed EIP-191 by the fleet signer and anchored on 0G Storage before the fill, chained so that dropping a record leaves a hole anyone can see. The mandate is a public commitment: get_mandate returns it verbatim, free forever. 10 tools (5 free, 5 paid).

Quickstart

Connect the Streamable HTTP MCP endpoint, read the mandate in force (free), then check the decision chain before paying for anything.

claude mcp add --transport http evidiq-helm https://mcp.evidiq.dev/helm/mcp

Read the mandate — free forever, this is the public commitment:

curl -s -X POST https://mcp.evidiq.dev/helm/mcp -H "content-type: application/json" -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"get_mandate","arguments":{}}}'

Or probe the public pricing discovery endpoint and the Skill file:

curl -s https://mcp.evidiq.dev/helm/x402

curl -s https://mcp.evidiq.dev/helm/skill.md

What Helm is for

Ten MCP tools

Five free tools support discovery and verification; five paid tools carry the evidence.

Paid execution and evidence tools

• decision_log — The signed decision chain over a window: which signal fired, which rule matched, what stop was set, at what price — sequence number, signature and anchor per record. (0.005 USDT0)
• signal_digest — The current ranked watchlist with its basis: which sources contributed and when the offline pass ran. (0.01 USDT0)
• risk_report — Live exposure: open positions, where each stop sits, distance to the daily loss limit, drawdown from the principal base. (0.01 USDT0)
• performance_attestation — A signed PnL statement for a window, tied to the decision chain, anchored on 0G — the number and the reasoning arrive together. (0.015 USDT0)
• mandate_compliance_audit — Walks every position and decision in a window against the mandate in force and lists violations — including a no-trade that should have been a trade. (0.03 USDT0)

Free preflight and verification

• helm_capabilities — Catalog: 10 tools, prices, mandate summary, trust model and boundaries. (free)
• estimate_cost — Exact USDT0 price for any paid tool, from the same table the gate charges from. (free)
• get_mandate — The rule set and risk limits currently in force, verbatim. Free forever. (free)
• chain_status — Freshness and integrity: last decision, current sequence number, gaps, anchored versus pending records. (free)
• verify_helm_decision — Offline verification of any record: recompute the digest, check the EIP-191 signature, walk the predecessor hashes, report gaps. Free forever. (free)

x402 pricing

Payments use x402 v2 exact scheme with USDT0 (6 decimals) on X Layer (eip155:196). Verification and settlement run through the official OKX Onchain OS Payment SDK.

Verification Log

The rules-engine fixture gate passed 14/14 before any tool existed; the decision-chain suite (digest, EIP-191, gap detection including omission) and the compliance audit suite pass; all 10 tools exercised live end-to-end by the OpenClaw agent on the VPS on 2026-08-03, and the Phase 2 gate assertions were measured from outside with the 402 gate on. Raw run + report in the helm repo.

Fixture gate (14/14)
  F1 strong signal, no positions        → enter, size 60 USDT, stop 97 000 ✓
  F2 signal below threshold             → wait (never a phantom trade)   ✓
  F3 daily loss limit reached           → halt even with a strong signal  ✓
  F5 instrument outside mandate scope   → wait                            ✓
  F7/F9 stop hit (long/short)           → exit (stop-hit)                ✓
  F10 price between stop and TP         → hold                           ✓
  F14 determinism                       → identical inputs, identical    ✓

Free Tools (HTTP 200)
  helm_capabilities · estimate_cost · get_mandate · chain_status · verify_helm_decision ✓
Paid Tools (HTTP 200 — bypass mode, Phase 1)
  decision_log · signal_digest · risk_report · performance_attestation · mandate_compliance_audit ✓
  0G anchored twice (root 0xf20ccb79… / 0x154af1…)

Phase 2 gate (bypass removed) — measured from outside:
  empty POST → 402 · no content-type → 415 · HEAD → 402 (75ms, no hang)
  5 paid bare {} → 402 · 5 free bare {} → 200
  payment quote all 5 paid tools → exact matches the price ladder (0.005/0.01/0.01/0.015/0.03)
