Ready to use your bitcoins (BTC) in Starknet’s DeFi ecosystem? This tutorial guides you through bridging BTC to Starknet using the Argent X wallet. For a quick primer on Starknet and Bitcoin differences or to set up your Argent X wallet (a prerequisite for this guide), check out our Starknet Onboarding for Bitcoiners article. We’ll explore bridging options like Layerswap, Garden Finance and Atomiq. to get you started.
Garden Finance
Open Garden Finance app.
Click on Connect. Then connect your Bitcoin wallet and your Starknet wallet.
Enter the amount and hit Swap.
You’ll have to sign the deposit transaction in your Bitcoin wallet. After a few minutes, your Argent X wallet will be credited by the equivalent amount of WBTC.
Atomiq
Open the app —> https://app.atomiq.exchange/ This is the main page. By default, the bridging route is BTC → Solana. We don’t want that.
Click on the SOL logo, select Starknet, then select Wrapped BTC (WBTC).
The swap section changes to this. Click on “Bitcoin wallet”, connect your Bitcoin wallet. Phantom, UniSat, Xverse & Magic Eden are available. Then click on “Connect wallet” and choose Argent X.
Enter the amount you’d like to bridge, tick the “Request gas drop” option if it’s a new wallet and execute the transaction.
After a few minutes, the transaction will be validated on Bitcoin and the funds will be credited in your Argent X wallet.
Layerswap
Go to LayerSwap
The homepage looks like this.
Configure the bridging route: Bitcoin --> Starknet. Layerswap gives you the option to fund your Starknet wallet with some ETH if your account is brand new. With an Argent X account you don't need this as it has a paymaster. We will sponsor your gas fees if you do not have ETH or STRK in your wallet.
Layerswap uses a manual transfer on the Bitcoin side. You'll have to send the corresponding amount to the generated address. After a few minutes, the transfer will be processed and your Starknet account will be credited.
With these bridging options, bringing your bitcoins into Starknet’s DeFi ecosystem is easier than ever. Pick your favourite method and start exploring new opportunities.
