Introduction to Crypto Custody
The term “custody” refers to the protective care of assets. In blockchain, it applies to cryptocurrencies like Ethereum Classic (ETC) and digital asset management. As explained in previous lessons, custody revolves around private key ownership—whoever holds the private key controls the assets linked to a public blockchain address.
This guide contrasts four custody models:
1. Traditional financial systems
2. Centralized exchanges
3. Custodial wallets
4. Non-custodial wallets

How Traditional Financial Systems Handle Custody
Financial Institutions as Asset Controllers
When you deposit money in banks or brokerage accounts:
– Assets become liabilities on the institution’s balance sheet
– You receive conditional access rights, not ownership
– Providers may freeze accounts or restrict withdrawals
This centralized model creates systemic risks, as seen in historical bank failures. Surprisingly, most stocks, bonds, and commodities follow this custodial pattern—you never truly “hold” these assets yourself.
Custody in Centralized Crypto Exchanges
The Illusion of Control
Platforms like Coinbase or Binance mimic traditional finance:
– Deposited crypto becomes an IOU from the exchange
– You rely on their security practices (and honesty)
– High-profile collapses (e.g., FTX) demonstrate the risks
“Not your keys, not your coins” remains crypto’s cardinal rule.
The Trap of Custodial Wallets
Brand Names ≠ True Ownership
Services like BitGo or Blockchain.com:
– Manage private keys on your behalf
– Require traditional login credentials (username/password/2FA)
– Can theoretically restrict access to “your” assets
These wallets offer convenience but sacrifice decentralization’s core benefit—self-sovereignty.

Non-Custodial Wallets: Real Decentralization
Taking Full Responsibility
True self-custody means:
– Generating and storing your own private keys
– Bearing complete security responsibility
– Enjoying uncensorable asset access
Popular options include:

FAQs: Custodial vs. Non-Custodial Wallets
Q1: Which is safer—custodial or non-custodial wallets?
A: Non-custodial wallets eliminate third-party risk but require stringent backup practices. Custodial options shift security burdens to providers.
Q2: Can I recover funds if I lose my non-custodial wallet keys?
A: Only if you’ve securely stored seed phrases. Unlike custodial services, there’s no password reset option.
Q3: Why do people use custodial wallets despite the risks?
A: Convenience factors like:
– Simplified transactions
– Integrated trading features
– Familiar login methods
Q4: Are hardware wallets necessary for non-custodial storage?
A: Not mandatory, but they significantly enhance security by keeping keys offline.
Q5: How do I identify if a wallet is non-custodial?
A: Check whether you:
1. Created the private key/seed phrase
2. Can export keys without provider approval
3. Maintain direct blockchain access
Key Takeaways
– Custodial models (banks/exchanges/wallets) control your assets
– Non-custodial solutions ensure true ownership via private keys
– Security trade-offs exist between convenience and self-reliance
