The most obvious use case for interop, IMO, is the laundry list of integrations that blockchains need to get an ecosystem going.

For instance, deposits & withdrawals to centralized exchanges, on/off ramps, native stablecoin issuance, price feeds, token bridges, etc.

Launch a chain & interop with one which has these.

We are utilizing the @thirdweb wallet for our MVP to create more interoperability with fiat and they even have a farcaster social auth coming too with AA.
Love the direction we are all heading where the wallet just does the thing despite your balance being spread across chains. ⛓️

yess and the cost for new integrations are insane. infra providers have a lil monopoly and will charge chains a ton bc they know we don’t have a choice but to pay 😭

It would be incredible if then you'd found pooled funded solutions to local on/off-ramping solutions so that not only one ecosystem needs to cover the costs associated to it.
