Definition
Custody risk is the danger of losing access to digital assets due to technical vulnerabilities, human error, or failure of a third-party custodian.
Why It Matters
Asset Loss: Often irreversible
Security Breaches: Hacking and phishing
Counterparty Failure: Custodian insolvency
Operational Risk: Poor security practices
Regulatory Risk: Changing compliance rules
Types of Custody
1. Self-Custody
User controls private keys.
Risks:
Lost keys
Device theft
Malware/phishing
2. Third-Party Custody
Exchange or custodian manages keys.
Risks:
Exchange hacks
Custodian mismanagement
Insolvency
Government seizure
3. Hybrid Custody
Multisig or MPC solutions.
More secure but complex.
Example
Alice holds 5 BTC and 20 ETH.
If private keys lost → total loss.
If exchange hacked → partial pooled loss possible.
