Ledger published a case study on CADD, the Canadian-dollar stablecoin issued by Tetra Trust. The core theme is straightforward: regulated on-chain money still needs offline key protection, auditable approvals, and strict custody boundaries. That makes it a clean cold-storage story. The post shows why institutional issuers keep choosing hardware-backed isolation instead of keeping reserve keys anywhere near internet-connected systems.
CADD is framed as Canada's first regulated Canadian-dollar stablecoin, backed 1:1 by reserves held in segregated bank trust accounts. Ledger says CADD selected Ledger Enterprise as the secure execution layer for key management and transaction authorization. The post emphasizes hardware-backed key management, offline isolation, and multi-approval governance for mint, transfer, and redemption flows.
For a regulated stablecoin issuer, key compromise is not just a technical incident. It can break mint/burn controls, weaken reserve trust, and create immediate compliance and counterparty risk. If operational keys are exposed, the fallout can include unauthorized transfers, frozen redemption processes, and a loss of confidence that is hard to recover.
Cold storage keeps the most sensitive signing material out of exposed environments, which sharply reduces remote attack surface. Combined with multi-approval policies, it makes unauthorized movement far harder even if a production system is breached. That is the practical value here: offline custody preserves control, auditability, and recovery options when live systems are under pressure.
