Invoke MMM from another (native) app

Hi,

We're building a native app which needs to interact with the ETH chain. Being native it means we cannot use the MMM embedded browser to interact with it directly.

I'm wondering if it's possible to invoke MMM from another app on iOS or Android to sign message or transactions, and send the result back to said app somehow?

Thanks!

Start by reviewing the mobile app's iOS and Android entry points and how it currently handles Ethereum message or transaction signing. Define the invocation and return flow for a native app, including what result must be sent back; the issue is complete only when that cross-app flow is specified and implemented for both platforms.
