Exchange lending versus DeFi: custody, costs and liquidity
Exchange and DeFi lending can both earn interest, but differ in control, exit conditions and risk. Compare all costs over the same period without assuming either always pays more.
Key differences
| Factor | Exchange lending with LendPace | DeFi lending |
|---|---|---|
| Assets | Held by exchange; tool uses API | Held by protocol contracts; control varies |
| Dependencies | Exchange, API and service | Contracts, oracles, chain and interface |
| Costs | Interest fees, subscription, possible transfers | Network, protocol and conversion costs |
| Exit | Loan terms or redemption conditions | Available liquidity and collateral constraints |
| Rates | Demand and matching conditions | Protocol utilization and market conditions |
DeFi is not limited to Ethereum mainnet. Network fees vary by chain and time, so a fixed high gas assumption cannot justify a paid tool for every small balance.
Two liquidity limits
Aave withdrawals depend on available pool liquidity. Assets used as collateral can also be constrained by the borrower’s position. No fixed maturity does not mean unconditional immediate withdrawal.
For exchange funding, LendPace’s lack of custody does not remove the exchange’s custody. Active Bitfinex loans cannot be recalled freely.
Before deciding
Check your asset, accessible chain or venue, amount, costs and timing needs. Promotional APRs may not apply to all capital. Smart-contract and exchange risks can be affected by the same event; do not assume they cannot occur together.
If you cannot explain a product’s exit and loss-handling rules, it is reasonable to wait before using it.
