This not the first project coming up with this new innovations of Bitcoin DeFi, Bitcoin layer 2 and all these Bitcoin subchain projects but they never end well.
Mintlayer came and nothing special about it till today,
The problem I always have this so-called Bitcoin layer 2 are always using EVM address starting with 0x to maximize transactions calling it on Bitcoin protocol, that's actually not real to me.
Build on Bitcoin and use Bitcoin address that starts with bc1 or 1, let's know where you leading the users to, EVM or Bitcoin chain, I don't find a project fulfilling when they claim to be Bitcoin DeFi while still using EVM address for transactions, that's sketchy to me.
