A few things that should be quick fixes:

• can you remove most of the code under common? None of it is actually used (aside from a few things in constants.ts)
• Remove the generic and lending SDKs, those are not being used in this subgraph
• In deployment.json there is already an orbit bridge configuration, can you move everything over to the orbit-bridge taxonomy instead of just orbit
• we should be using the latest version of the price library (the prices folder), just need to copy/paste it in
  • Note: you will need to rebase to the latest master branch in order to grab the newest price library

Once these are fixed, can you redeploy everything and link to your subgraphs in the header comment, thanks. Otherwise the rest of the code lgtm. Once all of this is done I will approve and I will let Vincent know for following up :)
