Overview
BTC Grow is a platform that lets Bitcoin holders earn a return on their coins without handing them over to a company. You connect a Bitcoin wallet, choose an amount, and your Bitcoin goes to work earning interest that gets paid back to you in Bitcoin1. It is aimed at people who want their Bitcoin to do more than sit idle but don't want to give up control of it.
The yield comes from Cardano, a separate blockchain with an active lending market. BTC Grow acts as a bridge: your Bitcoin stays on the Bitcoin network, while a matching amount is put into Cardano lending pools run by an affiliated project called Danogo, where borrowers pay the interest you earn2. Because it is non-custodial, no central company ever holds your coins.
Key Features
- Keep control of your Bitcoin. Your coins stay locked on the Bitcoin network under your own wallet the entire time, rather than being deposited with a company that could freeze or lose them1.
- Earn interest paid in Bitcoin. The return comes from real borrowing demand in Cardano lending pools, not from a project handing out its own coins, and it is paid back to you in Bitcoin2.
- Start with just a Bitcoin wallet. Unisat, OKX, and XVerse wallets are supported, so you don't need to set up a separate Cardano wallet or manually move funds between chains3.
- No lock-up period. You can withdraw whenever you want, with no fixed staking term and no penalty for pulling your Bitcoin out early1.
- Cross-chain handled for you. A bridge run by Wanchain moves value between Bitcoin and Cardano behind the scenes, spreading control across independent operators instead of a single custodian2.
What to Expect
Using BTC Grow follows a short, guided flow: connect a Bitcoin wallet, choose how much to stake, confirm the transaction, and then watch the balance grow4. When you stake, your Bitcoin is locked and a wrapped version called wanBTC is created on Cardano and supplied to a Danogo lending pool; when you withdraw, that process runs in reverse and native Bitcoin returns to your wallet2. The cross-chain step takes time to settle rather than being instant, so moving funds in and out is not immediate3.
BTC Grow is an early-stage project. It has run an incentivized testnet and offers a beta app, and its light paper states that a third-party audit of its own smart contracts is planned before the full mainnet launch2. There is no BTC Grow token; during the testnet, rewards were paid in DANO, the token of the affiliated Danogo lending project5.
