Reduce the signing blast radius
We review where keys can be accessed, which components can request signatures and what limits remain if a server or operator account is compromised. Recommendations may include isolated signers, policy checks, withdrawal restrictions, rotation and emergency shutdown procedures.
This is a technical architecture review, not a certification or legal compliance opinion.
Delivery and operational boundaries
TierZero provides software engineering, testing, documentation and deployment support. The client controls its infrastructure, accounts, credentials, wallets and product decisions. We do not custody client or end-user assets, transmit funds on a client's behalf, operate customer trading accounts, recommend specific investments or guarantee financial results. Production use remains subject to the client's legal, compliance and risk review.
