Hi,
Wanted to let you know that we have built a multi-chain monitoring SDK that addresses some of the use cases that you’ve mentioned i.e. connection with Smoldot and pallet-specific modules. We also have an example application for monitoring sovereign account assets across parachains.
You can find all the details in our post, including the Github repo link and our future plans on building a potentially decentralised network of monitoring agents. Would love to know if what we are building is useful for you and what capabilities you would like to see in a multi-chain monitoring solution.
