Multichain squid

This squid captures TakerAsk, TakerBid, Royalty Payments, CancelOrderNonce, and Cancel Multiple Nonces events for the Dotsama NFT Marketplace on ASTAR and MOONBEAM, stores them in the same database and serves the data over a common GraphQL API.

The Astar processor is located in src/astar and similarly the Moonbeam processor can be found in src/moonbeam. The scripts file commands.json was updated with the commands process:astar and process:moonbeam to run the processors.

You can find some useful hints on developing multichain squids on the dedicated documentation page.

Dependencies: Node.js, Docker, Git.
