Step 1: Use EVM wallet to add Merlin Chain, portal: https://chainlist.org/?search=merlin
Step 2: Merlin Chain uses BTC as GAS and needs to cross-chain
1️⃣Use the official cross-chain bridge to transfer the BTC from your brc20 wallet: https://merlinchain.io/bridge
The advantage is that it can be interactive and there may be airdrops in the future. The disadvantage is that the speed is too slow and the GAS is very high.
2️⃣Now switch your wallet to BSC link, then choose BEP20 to your wallet when withdrawing $BTC from the exchange, and then use the third-party tool to directly cross to Merlin Chain
