The meetup is focused on contract development. Very tech stuff - down to the byte code. Not frontends and JS Frameworks - there are other meetups for those.

Example topics will be comparison of proxies, their gas, size, ect. Other talks will be about cross chain / layer calls, blind signing, security, clever hacks, and more. Regarding contracts level - any smart contracts, i.e. not limited to EVM based.
