Requests are evaluated based on the written brief. All requests should include a 2–4 page summary brief. If there is a fit, you will receive an engagement overview and a scope confirmation path.

Required: 2–4 page summary brief

Attach (or provide a secure link to) a 2–4 page summary brief. The brief should be written for an internal audience and should avoid marketing language.

  • System context: what is being reviewed (architecture, protocol/ledger, payments/settlement)
  • Decision pending: what decision you need to make and by when
  • What is at risk: capital, regulatory exposure, operational risk, reputational risk
  • Threat model: plausible adversaries and failure scenarios (internal and external)
  • Assumptions: dependencies, trust assumptions, third parties, control boundaries
  • Constraints: regulatory, operational, integration, timeline constraints
  • Closure definition: what “done” looks like (e.g., memo suitable for GC/CRO/committee review)
  • Confidentiality: whether an NDA is required before sharing materials
  • Materials available: architecture diagrams, specs, threat models, prior audits, incident history (if any)

Requests that do not include the brief are typically not evaluated.

Use a secure link (e.g., expiring link) if needed. If an NDA is required before sharing, state that here.
Typical fixed-scope engagements are commissioned between $25,000–$150,000 depending on scope and complexity. Not all requests are accepted. Pricing is discussed after suitability and scope are established.
