Your part in the engagement
What do you need from me?
Describe the custody or access question. After scope and handling are agreed, provide sanitized control documentation and an owner for follow-up questions.
What access is required?
Documentation and agreed non-secret observations only. We do not request keys or seed phrases, move funds, or inspect private balances.
What happens after delivery?
You receive findings, unsupported claims and missing evidence to address. Your team owns control changes; the report does not establish solvency or certify custody security.
