Choosing between DeFi lending protocols means weighing more than just APR. Chainflip, Aave, and Compound each serve different borrower profiles with distinct trade-offs around collateral, fees, and risk. This guide breaks down what matters for practical decision-making.
The Core Difference: Native vs Wrapped Collateral
The most fundamental distinction between these protocols is how they handle Bitcoin collateral. Aave and Compound operate on Ethereum and accept wrapped BTC variants (primarily WBTC, which holds 81% market share among wrapped Bitcoin with 128.8K BTC supply). Chainflip accepts native BTC directly on the Bitcoin blockchain.
This isn't just a technical detail. Wrapped BTC introduces custodial trust assumptions that native BTC avoids entirely. When you deposit WBTC on Aave, you're trusting both the lending protocol and the custodian backing the wrapped token. For a deeper exploration of these trust trade-offs, see our breakdown of native vs wrapped BTC lending.
Chainflip's custody model relies on a decentralized validator network that secures your collateral without a centralized custodian. Your BTC stays on the Bitcoin chain, not a derivative on Ethereum.
Protocol Comparison Table

|---|---|---|---|
BTC Collateral Type | Native BTC | WBTC, cbBTC | WBTC |
BTC Borrow APR | Variable (typically 0.5-5%) | Variable (typically 0.5-4%) | |
Max LTV | 80% | 73-80% (varies by asset) | 65-80% (varies by market) |
Liquidation Model | Soft liquidation | Hard liquidation | Hard liquidation |
Gas Costs | Bitcoin network fees only | Ethereum gas | Ethereum gas (or L2) |
TVL | Growing | ||
Chains Supported | Bitcoin, Ethereum | 14+ chains | 6 chains |
Borrow Markets | USDC, USDT, BTC | 100+ assets | 4-6 per chain |
Rates and True Borrowing Costs
Headline APR tells only part of the story. Chainflip Lending currently offers 3.13% APR on native BTC loans. Aave and Compound rates fluctuate based on utilization, but their BTC borrowing markets typically range from 0.5% to 5% depending on market conditions.
Where costs diverge significantly is in transaction fees. Borrowing on Aave or Compound means paying Ethereum gas for every interaction: depositing collateral, borrowing, repaying, and withdrawing. During high congestion, a single borrow transaction can cost $20-50 or more. Chainflip's collateral deposits use Bitcoin network fees, which have historically been lower and more predictable.
Neither protocol charges origination fees. All three use utilization-based rate models where interest moves up as pool utilization rises and down as it falls. For a detailed rate comparison across DeFi and centralized options, check our BTC loan rates comparison.
Liquidation: Hard vs Soft
Aave and Compound use hard liquidation. When your loan-to-value ratio exceeds the liquidation threshold, liquidators can immediately repay a portion of your debt and claim your collateral at a discount (typically 4-10%). This happens in a single transaction with no warning beyond on-chain health factor monitoring.
Chainflip implements soft liquidation. Rather than immediate forced selling, the protocol gradually converts collateral to cover the position as it approaches the liquidation threshold. This gives borrowers more time to respond and typically results in less value lost compared to hard liquidation events.
For borrowers holding volatile collateral, this difference matters. A sudden 15% price drop on Aave could trigger liquidation before you can add collateral. Chainflip's soft approach provides a buffer.
When to Use Each Protocol
Choose Chainflip When
You hold native BTC and want to borrow without wrapping it. The 80% max LTV, soft liquidation, and absence of wrapped asset trust assumptions make it ideal for Bitcoin holders who prioritize keeping their BTC on the Bitcoin chain. If you're borrowing stablecoins against BTC for any reason that doesn't require staying within the Ethereum DeFi ecosystem, Chainflip is the more direct path.
Choose Aave When
You need maximum flexibility across chains and assets. With $14.162 billion in TVL and deployment on 14+ chains, Aave offers the deepest liquidity and widest asset selection. If you're actively composing with other Ethereum DeFi protocols or need to borrow obscure tokens, Aave's breadth is unmatched.
Choose Compound When
You want a simpler interface and plan to borrow primarily on Ethereum L2s where gas costs are lower. Compound V3's focused market structure (single collateral asset per market) reduces complexity. Its $1.8 billion TVL provides sufficient liquidity for most users without Aave's sprawl.
Trust Assumptions Worth Considering
Every lending protocol requires trust in something. With Aave and Compound, you're trusting the smart contract security (both are battle-tested), the wrapped BTC custodian's solvency, and the oracle price feeds. WBTC specifically requires trusting BitGo's custody and minting process.
Chainflip requires trust in the validator network that secures deposits and the protocol's cross-chain messaging. There's no wrapped token issuer in the middle. The protocol has processed over $3 billion in cross-chain swap volume, demonstrating the validator network's operational track record.
Neither approach is objectively superior. They represent different risk profiles that may suit different users.
Making Your Decision
For Bitcoin-native borrowers who want the most direct path to liquidity without wrapped assets, Chainflip Lending offers a compelling combination: competitive rates, soft liquidation, and native BTC collateral secured by validators rather than centralized custodians.
For users already embedded in Ethereum DeFi who need composability with other protocols, Aave's scale and asset variety remain the default choice despite the wrapped collateral trade-off.

What's the main difference between Chainflip and Aave for Bitcoin loans?
Chainflip accepts native BTC directly on the Bitcoin blockchain, while Aave requires wrapped Bitcoin (WBTC or cbBTC) on Ethereum. This means Chainflip avoids the additional trust assumptions that come with wrapped token custodians.
Which protocol has the lowest borrowing rates?
Rates fluctuate across all three protocols based on utilization. Chainflip currently offers 3.13% APR on native BTC loans. Aave and Compound typically range from 0.5-5% for BTC borrowing, varying with market conditions. Total cost also depends on gas fees, which are higher on Ethereum mainnet.
What happens if my loan gets liquidated on each platform?
Aave and Compound use hard liquidation where liquidators immediately claim collateral at a discount when your position becomes unhealthy. Chainflip uses soft liquidation, which gradually converts collateral rather than forcing an immediate sale, giving borrowers more time to respond.
Can I use the same collateral on all three protocols?
Not directly. Chainflip accepts native BTC on the Bitcoin chain. Aave accepts WBTC and cbBTC on Ethereum. Compound accepts WBTC. You cannot deposit the same BTC across multiple protocols simultaneously without first wrapping or unwrapping it.
Which protocol should I choose for occasional borrowing?
For infrequent borrowers, gas costs become a larger factor. Chainflip's Bitcoin-based collateral deposits avoid Ethereum gas entirely. If you're on Ethereum L2s, Compound V3 offers lower gas costs than Aave mainnet. For users who prioritize keeping BTC native and want soft liquidation protection, Chainflip is the strongest fit.
