DeFi vs CeFi Crypto Loans: After Celsius, BlockFi, and FTX

·8m read·By the Zeeria team

Before 2022, retail crypto borrowers used Celsius, BlockFi, and Voyager because the UX was identical to a regular bank — a clean app, a customer-service phone number, a fixed rate. By December 2022, all three were bankrupt. Total user losses across CeFi lenders that year exceeded $10 billion. The wreckage reshaped the lending landscape: most retail flow rotated to non-custodial DeFi protocols where, by design, no balance sheet exists to collapse. This guide is the honest 2026 comparison of what remains.

What actually broke in 2022

The CeFi lenders that failed shared a single design choice: they took user collateral, held it on their balance sheet, and re-lent it (or proprietary-traded with it) to generate yield. Celsius alone rehypothecated user BTC into Anchor Protocol on Terra — when Terra collapsed, the loss propagated back into the user's collateral. BlockFi extended uncollateralized credit to FTX's sister hedge fund Alameda; when FTX failed, BlockFi's receivables vaporized.

The structural problem wasn't the centralized model per se — it was that user collateral was treated as the lender's working capital. When the lender's investments soured, user funds were not segregated. By the time bankruptcy filings surfaced, withdrawals had already been frozen.

DeFi protocols have a different structure: user collateral lives in smart contracts, there is no operator that can borrow against it, and there is no balance sheet to fail. When Celsius froze withdrawals on June 12, 2022, Aave kept processing borrows and repayments without interruption. That difference is the entire post-2022 thesis for non-custodial.

The 2026 landscape

DeFi (non-custodial)

  • Aave V3 / V4 — multi-asset, cross-chain. ~$30B TVL across all chains. The default starting point for sophisticated users. Variable APR set by utilization curves.
  • Morpho Blue — permissionless markets with custom risk parameters per market. Each market is isolated; an exploit in one cannot drain another. Powerful but complex.
  • Spark Protocol — Sky/Maker-affiliated, focused on USDS and DAI borrowing. Tight integration with Sky's stablecoin issuance.
  • Compound V3 — single base asset per market (e.g. USDC market on Base). Simpler model, fewer assets supported.
  • Zeeria — single-asset focus (WBTC↔USDC on Base only), small attack surface, deliberately boring.

CeFi survivors (post-2022)

  • Nexo — Bulgarian-based, public proof-of-reserves since 2022, no rehypothecation declared. Offers loans at 0-15.9% APR depending on tier. Loyalty token structure ties best rates to NEXO holders.
  • Ledn — Cayman-based, focused on BTC and USDC. Custody-only, transparent about not rehypothecating. Higher rates than Nexo (~9-13%) but cleanest structure of the survivors.
  • Salt Lending — US-based (Colorado), longest-running CeFi lender (since 2018). Operates through a Cayman subsidiary; reputation rebuilt slowly post-2022. Lower volume than Nexo or Ledn.
  • Coinbase's built-in BTC loans — relaunched 2024 via a Morpho Blue integration, technically a DeFi product behind a CeFi UI. The collateral lives in a Morpho smart contract Coinbase publishes the address of.

Who should use which

The honest answer is that DeFi wins for users who can self-custody and who treat smart-contract risk as a cost of doing business. CeFi wins for users who need handholding (a real customer-service line, fiat on-ramps integrated, account recovery if they lose keys) and who trust the specific lender's post-2022 governance.

  • Choose DeFi if: you can read your wallet's transaction history, you're comfortable using a non-custodial wallet, you want lower rates, you value withdrawing whenever you want with no restrictions, and you accept smart-contract risk.
  • Choose CeFi if: you want a fixed-rate loan, you want fiat directly to a bank account, you need account recovery, you value customer support, and you trust your specific lender's reserve segregation.
  • Don't choose either if: you can't afford to lose the loan collateral. Crypto-backed lending is for people whose long-duration thesis on the collateral is strong enough to absorb a forced sale at the worst time.

Hybrid: CeFi UX over DeFi rails

Some 2026 products hide DeFi mechanics behind a CeFi UX. Coinbase's BTC loan relaunched in 2024 is the most prominent: you tap "Borrow" in the Coinbase app, and Coinbase routes your collateral into a Morpho Blue market on the back end. You get the DeFi rates and the smart-contract custody guarantee, but the UX is the Coinbase app. For users who want DeFi's economics with CeFi's polish, this category will likely grow through 2026-2027.

What about Zeeria?

Zeeria is decisively non-custodial DeFi. The protocol takes WBTC into a smart contract on Base; the contract address is publicly verifiable on Basescan. Admin actions go through a 3-of-5 Gnosis Safe + 48h Timelock. The operator (Intermo PSP FZCO, Dubai) cannot freeze user collateral or rehypothecate it.

You can open the app, claim a starting allocation from the welcome bonus page, and run the full deposit-borrow-repay loop in a few minutes.
