CeFi (Centralized Finance)

What CeFi includes

The CeFi label covers most of the crypto financial products that look familiar to traditional-finance users:

• Centralized exchanges (Coinbase, Binance, Kraken) — order-book trading venues that custody user funds.
• Crypto banks and lenders — historically Celsius, BlockFi, Voyager, Genesis. Largely defunct after 2022.
• Crypto debit cards and payment apps — Crypto.com, Cash App's bitcoin features, PayPal's crypto offering.
• Custodial wallets — wallets where the provider holds the private keys (most exchange-attached wallets).
• Crypto-native brokers — services like Robinhood Crypto and SoFi.

The defining feature is custody: the user deposits crypto with a centralized operator, who holds it on their behalf and is responsible for keeping it secure.

Why people use CeFi over DeFi

Despite DeFi's transparency and self-custody benefits, CeFi remains the dominant on-ramp for new users for a few reasons:

• Familiar UX. A Coinbase account works like a Schwab account. Self-custody requires understanding seed phrases, gas, and transaction signing.
• Customer support. Lose access to your account? Call Coinbase. Lose your seed phrase to a self-custody wallet? The funds are gone.
• Regulatory clarity (sort of). Major regulated CeFi platforms have explicit licenses and tax reporting. DeFi protocols still occupy ambiguous regulatory territory.
• Advanced features. Options trading, margin, prime brokerage, and institutional services are largely on CeFi platforms.
• Fiat connectivity. Buying crypto with USD almost always involves a CeFi venue at some step.

What 2022 exposed

The May–November 2022 collapse of Terra/LUNA, Celsius, Voyager, BlockFi, FTX, Genesis, and others was the largest CeFi crisis in crypto history. Tens of billions of user dollars were frozen, lost, or recovered only after multi-year bankruptcy proceedings.

The pattern was similar across cases: lenders accepted user deposits, promised yield, and lent or invested the funds in ways that lacked the disclosure or risk management of regulated banks. When markets fell, the lenders were insolvent and froze withdrawals. Users with funds at these platforms lost most of their balance.

The lesson — already known to crypto-native users but learned painfully by retail — was that "crypto in a CeFi account" is not the same as "crypto." It's an IOU from a counterparty, with all the counterparty risk that implies. The crypto-native phrase that crystallized after these failures: "not your keys, not your coins."

What survived and what changed

Major regulated exchanges (Coinbase, Kraken) emerged stronger; opaque crypto lenders mostly didn't survive. The aftermath drove three structural changes:

• Proof of reserves. Major exchanges now publish cryptographic proofs of customer balances and held assets, attempting to demonstrate solvency in a way that traditional auditors couldn't replicate at the speed needed.
• Reduced yield programs. The high-yield CeFi lending products that drove the 2021 boom mostly disappeared. Surviving products are smaller, more conservative, and more often disclosed as bank-style risk products.
• Self-custody resurgence. Hardware wallet sales surged in late 2022 as users moved funds out of failed lenders.

CeFi today

The largest CeFi activity by volume remains spot trading and stablecoin custody. Traditional finance has continued moving in: BlackRock and Fidelity now run spot Bitcoin and Ethereum ETFs; large banks (JPMorgan, BNY) have built crypto custody and tokenization desks. The line between "CeFi" and traditional finance has blurred substantially since 2022, while the more speculative end of CeFi has largely vanished or migrated on-chain.
