It bothers me seeing people asking for a polymarket on base. Just go use polymarket, the whole point of building consumer-friendly apps is the chain literally should not matter. Biases are showing.

Curious about this as i havnt seen it yet - but have yiu come across an app that requires an external wallet (metamask, etc), and then when you need to interact with their contracts, looks at where you have eth amd prepackages up all the txns to bridge and interact? 

Eg, i have eth on base, but the app im interacting with has contracts deployed on polygon. The app looks at my connected address, see that i have eth on base, and preps the txns needed to bridge and makes it easyish so i dont have to do it all externally? Ideally with as few txns from my perspective as possible (could be xferring eth on base to custodial and then *hand wave* sponsor bridge to polygon, so i can start using it right now)

Check out Okto wallet. Not available in all countries yet but soon.
