What is the most challenging aspect of building onchain games?

doing the right thing.
working hard.
being optimistic.
putting the team over the individual.
pushing boundaries with creativity.

A lot of ux (batched txs, user onboarding) can be solved with embedded or smart wallets, but you want to allow users to use their existing wallets too. I know solutions like Privy's account linking exists, but so far I am a bit wary of centralised embedded wallets. I don't know yet what could be the solution except for maybe an sdk that can abstract and unify dev-ex when dealing with different types of wallets (for EOA it would use erc7702 perhaps, and for smart wallet something more appropriate?)
