couple of things,

• could you please add the link to your hosted service deployment too for us to try out some queries.
• There are some lint issues not introduced by your changes, but would be great if you could resolve those. And run prettier.
• We update versions.subgraph here, but I see erc20 subgraph has separate deployments for each year, we'll take care of that. cc @melotik

• Build checker: you can see the issues it is running into using messari build erc20 -l
