Custodial Risk

Definition ∞ Custodial risk is the potential hazard that arises when a third party holds control over an individual’s digital assets. This risk involves the possibility of loss due to the custodian’s insolvency, security breaches, operational failures, or fraudulent activities. When a user delegates control of their private keys to an exchange or service, they become reliant on that entity’s integrity and security measures. The custodian’s failure to safeguard assets or honor withdrawal requests constitutes the primary exposure.
Context ∞ The debate around custodial risk in crypto news often highlights incidents of exchange hacks or platform collapses, underscoring the importance of self-custody. Regulatory bodies are increasingly examining custodial practices, particularly for institutions managing significant digital asset holdings. A key consideration for investors involves evaluating the security protocols and insurance provisions offered by custodial service providers. Future trends indicate a growing demand for audited and transparent custodial solutions.
