A new era of Bitcoin summer and liquidity is coming to Starknet and there’s no denying it.

If you're not aware, the Starknet Foundation has launched BTCFi Season, which will offer various opportunities to put your Bitcoin to work through Starknet. To prepare, you should move your BTC, which you've been holding, to Starknet right away!

This is a simple guide on bridging BTC (from Bitcoin) to wBTC to Starknet.

Here are the prerequisites for bridging Bitcoin (BTC) to Starknet:

1. Most obvious one - Have a Bitcoin wallet which is funded with BTC. Choice of wallets: Xverse, Phantom, Unisat and MagicEden.

2. Next, create a Starknet wallet. You can choose Ready or Braavos.

3. Now, choose any of the 3 websites mentioned below to swap. Layerswap supports sending BTC to a wallet address for swap if incase you don’t want to connect your wallet to the website.

   

4. Receive BTC in the form of wBTC. If you want, you can choose to swap BTC to ETH, STRK or any other token directly depending on each platform (we’ll mention this too below).

5. Done! If you want to swap some wBTC for gas, you do do it via Avnu, or Fibrous Finance.
