Blockchain – Connecting WBTC to Laysat mainnet

There is a problem with bridging. I came across a Twitter post (now blocked) advertising the BTC Layer 2 inscription. I followed their instructions and went to the site and linked my BTC to WBTC. The next step was to replace WBTC with CSAS on the laysats mainnet, the native token to imprint on. The problem is that the gas for swap or reverse bridge release is CSAS. This is question 22. Do I need CSAS on Laysats mainnet to convert my WBTC to CSAS? Any help would be greatly appreciated. Can someone please send me a small amount of BTC to send me CSAS? My abilities are limited. thank you all
