How it really works
Track your collateral headroom in the app
Send BTC
You deposit native BTC and the app automatically converts it to wBTC (1:1), the version of Bitcoin that runs on the networks where Aave operates. The round trip works: wBTC converts back to native BTC on the way out.
wBTC becomes collateral on Aave
The wBTC is deposited as collateral in an Aave protocol contract. The protocol computes the maximum you can borrow, up to about 73% of the collateral's value, and you choose how much. The less you borrow, the further you are from liquidation.
Receive USDC instantly
USDC lands in your wallet in minutes, at ~5% p.a. variable. No term, no installments: interest accrues on the outstanding balance, and only on it.
Track the headroom on your collateral
The app shows your position's health in real time. If BTC drops, add collateral or repay part of the debt. The liquidation point sits at about 78% of the collateral's value.
Repay and get your BTC back
Return the USDC whenever you want, partially or in full. Your wBTC is released instantly, converts back to native BTC, and can go to any Bitcoin wallet, with no early-repayment penalty.
Why Chainless
Liquidity without selling your BTC
You get USDC in minutes and keep your position: repay and your BTC comes back in full, to your keys. If BTC appreciates along the way, that upside is yours.
Credit without asking permission
No credit check, no committee, no term, no installments. Collateral on Aave is the only requirement, and audited contracts execute the rules, verifiable on the blockchain.
The rate comes from the market, not a committee
Around 5% p.a., variable, set by USDC supply and demand on Aave. Personal credit in Brazil tops 30% p.a., and the difference is structural.
Self-custody end to end
The collateral is locked in an Aave contract, on your keys. Chainless is a technology provider and does not custody assets. The wallet recovers through your Google or Apple account.
The questions that matter
Not the question you had? There are real people answering in the app.
Why not just sell the BTC?
Selling closes your position: if BTC rises afterward, you are out. Selling can also have tax implications a loan does not have, because a loan is not income. Talk to your accountant. With BTC as collateral you get USDC now and your BTC back when you repay. Any appreciation along the way is yours.
How much can I borrow?
On Aave, the wBTC maximum sits around 73% of the collateral's value: R$100,000 in BTC unlocks up to ≈ R$73,000 in USDC. In practice, borrow well below that. Borrowing 50%, BTC can drop about 35% before you approach the liquidation zone. You pick the amount in the app.
What if BTC drops? When am I liquidated, and how much do I lose?
Liquidation starts when your debt exceeds about 78% of your collateral's value. The protocol sells part of your wBTC, generally up to 50% of the debt per event, with a penalty of about 6.5% that goes to the liquidator. It is not all-or-nothing: you can add collateral or repay part before you get there. The app shows your distance from that point in real time.
Does the rate change? What does it really cost?
Yes, the rate is variable, around 5% p.a. today, set by USDC supply and demand on Aave. Borrowing R$50,000 costs ≈ R$2,500 a year at that level, about R$208 a month. Personal credit in Brazil easily tops 30% p.a. Check the live rate in the app.
Is there a term, installments, or a credit check?
No. No due date, no monthly installment, no credit score or proof of income, because the collateral is the only requirement. Interest accrues on the outstanding balance and you repay whenever you want, partially or in full. The only rule is to keep your debt below the liquidation point.
Who is on the other side lending?
The USDC comes from Aave liquidity pools. Aave is one of the largest and most audited onchain credit protocols, live since 2020. No company sets your rate or freezes your account: smart contracts execute the rules, and you can verify everything on the blockchain.
Is the BTC still mine?
Yes. Your BTC becomes wBTC (1:1) and is locked as collateral in an Aave protocol contract, on your keys. Chainless is a technology provider and does not custody your assets. The wallet recovers through your Google or Apple account.
How do I repay and get my BTC back?
Return the USDC (principal + accrued interest) right in the app, all at once or over time. Once repaid, your wBTC is released instantly, converts back to native BTC, and can go out to any Bitcoin wallet. No early-repayment penalty.
The risks
What can go wrong, written down before you invest.
- 01Liquidation risk: if BTC drops and your debt exceeds about 78% of the collateral's value, the protocol sells part of your wBTC. The penalty is about 6.5%. The protection is to borrow little, watch the alerts and keep spare collateral.
- 02The rate is variable and can rise when USDC demand on Aave increases. There is no guaranteed rate, so track it in the app.
- 03Smart contract risk: Aave is audited and has run since 2020, but DeFi protocol vulnerabilities exist and have been exploited elsewhere.
- 04Regulation and taxes: under current rules a loan isn't a sale for tax purposes, but Brazilian crypto regulation is evolving. Document the operation and talk to your accountant.
