Aave dominates DeFi lending with $14.49 billion in TVL as of May 2026. For Bitcoin holders, it offers one path: wrap your BTC into wBTC, then deposit it as collateral. This works, but it introduces dependencies that native Bitcoin lending protocols can avoid entirely.
Chainflip takes a different approach. You can borrow against native BTC without wrapping, bridging, or trusting third-party custodians. The result is a cleaner collateral structure, better rates, and a liquidation model that protects borrowers during volatility.
Collateral Types: Native BTC vs Wrapped Bitcoin
Aave requires wBTC as collateral for Bitcoin-backed loans. This means your BTC must first be wrapped through BitGo or another custodian before you can deposit it. The process adds friction, and it introduces counterparty risk that exists for the entire duration of your loan.
Aave currently holds over $4.3 billion in wBTC collateral. That represents significant exposure to the wBTC bridge and custodial infrastructure. If something goes wrong with the wrapper, every borrower using wBTC as collateral faces potential issues.
Chainflip accepts native BTC directly. Your Bitcoin stays on the Bitcoin network, secured by Chainflip's decentralized validator set using threshold signatures. No bridges, no custodians, no wrapped token dependencies. This is the same native BTC lending architecture that eliminates the wrapper entirely.
Borrowing Rates: 3.13% APR vs Variable Rates
Chainflip offers BTC-backed loans at 3.13% APR. This rate is fixed and predictable, making it straightforward to calculate your borrowing costs over time.
Aave uses variable interest rates that fluctuate based on utilization. For wBTC specifically, there's an unusual dynamic: supply yields sit near 0% due to low utilization. On Aave V3 Ethereum, roughly 43,400 wBTC is supplied while only about 1,400 wBTC is actively borrowed. This 3% utilization means suppliers earn almost nothing.
For borrowers on Aave, this low utilization can mean favorable rates during calm periods. But rates spike during high demand, and you have no certainty about what you'll pay next month. Chainflip's fixed 3.13% APR removes that uncertainty.
Loan-to-Value and Liquidation Mechanics
Both protocols cap LTV at 80%, but their liquidation approaches differ significantly.
Aave uses traditional liquidation auctions. When your collateral ratio drops below the threshold, liquidators can purchase your collateral at a discount. During market stress, this can mean selling your BTC at panic prices precisely when you'd least want to sell.
Chainflip implements soft liquidations. When your collateralisation falls below the threshold, the protocol starts unwinding your loan gradually using near-market rates rather than fire-sale pricing. This protects borrowers from the worst effects of volatility spikes. You keep more of your collateral compared to hard liquidation models that dump assets at discounted prices.
Trust Assumptions Compared
Aave's trust model for BTC lending involves multiple layers. You trust the wBTC custodian to hold and redeem Bitcoin. You trust the bridge infrastructure to remain secure. You trust that the wrapped token maintains its peg. Each layer adds potential failure points.
Chainflip's model consolidates trust into a decentralized validator network. Your BTC is secured by validators using threshold signatures. There's no centralized custodian holding your collateral. The protocol coordinates custody without any single entity controlling the funds.
This isn't about one model being absolutely trustless. Both protocols require some trust assumptions. But Chainflip's approach eliminates the specific risks associated with wrapped tokens and centralized bridge custodians.
Protocol Economics
Both protocols capture fees from lending activity, but they route those fees differently.
Aave distributes interest payments to liquidity suppliers and uses a portion for protocol reserves and AAVE staker incentives.
Chainflip captures 20-30% of lending fees for buy-and-burn or staking rewards. This creates direct value accrual to FLIP holders from lending activity. The FLIP 2.1 tokenomics update connects protocol revenue to staker returns.
When Each Protocol Makes Sense
Aave works if you already hold wBTC or need to interact with Ethereum DeFi ecosystems that require ERC-20 tokens. Its deep liquidity and established track record matter for larger positions.
Chainflip fits if you hold native BTC and want to keep it native. You avoid wrapping costs, eliminate bridge dependencies, and benefit from soft liquidations that protect your collateral during volatility.
For Bitcoin holders who prioritize keeping their BTC on the Bitcoin network, Chainflip's native approach offers meaningful advantages. The 3.13% fixed rate, 80% LTV, and soft liquidation mechanics create a borrowing experience designed specifically for Bitcoin.

What's the main difference between Chainflip and Aave for BTC lending?
Chainflip accepts native Bitcoin directly as collateral, while Aave requires you to wrap BTC into wBTC first. This means Chainflip eliminates bridge and custodian dependencies that come with wrapped tokens.
What are the current lending rates on each platform?
Chainflip offers a fixed 3.13% APR for BTC-backed loans. Aave uses variable rates that fluctuate with utilization, and wBTC supply yields currently sit near 0% due to low borrowing demand.
How do liquidations work differently?
Aave uses traditional liquidation auctions where liquidators buy collateral at a discount during margin calls. Chainflip uses soft liquidations that gradually unwind loans at near-market rates, protecting borrowers from fire-sale pricing during volatility.
What's the maximum LTV on both platforms?
Both Chainflip and Aave cap loan-to-value at 80% for Bitcoin collateral, though their liquidation mechanisms for handling undercollateralized positions differ significantly.
Which platform is better for Bitcoin holders?
Chainflip is designed specifically for Bitcoin holders who want to keep their BTC native. You avoid wrapping costs, eliminate bridge risks, and benefit from soft liquidations. Aave makes more sense if you already hold wBTC or need deep integration with Ethereum DeFi.
