Indexing is key to great Ethereum apps. But it's harder than it should be! Here's how we made ours work & what we'd like to see in the future https://daimo.com/blog/posts/less-terrible-ethereum-indexing

Thank you for writing this. * Gets out soapbox* So many assumptions about reliability in the space, especially at scale, fail as invariants. I know this is distributed systems 101 but it becomes a lot less fun around money/tokens. This is amplified by the fact that often times many users access services through bespoke APIs or play around on chains that have poor evm support, ie. Multicall try all suddenly reverting after certain block number whereas before it worked normally. Again I get that this is software development but I do want people to know that it's a lot of these long tail, annoying, niche problems and people encounter day to day and that is a lot of the job. *Puts away soap box* Directly addressing the article a lot of the process resonates I love that you are building this!

Still curious, though—what's the best third-party indexer out there? Do any support dynamic address filters?

Great article! I've worked on several projects where I had to build indexers, and they all follow a similar approach to your v3—'Simplify, then add lightness.' Practice definitely proves it!

For general contract based indexing I heard goldsky is really good. For asset transaction / portfolio tracking indexing, have you tried debank or zerion API?

Having to use traces to get ETH transfers is so painful. Why is that the design? It's like the most basic thing you can do in a transaction and yet it's so hard to process.

Thanks for sharing your challenges! I think I heard @nonlinear.eth say they ended up rolling their own indexing as well for hypersub. It makes sense that indexing-as-a-service would be a hard problem, so much of the data reqs are app-specific.

Having written a couple of these from scratch…I feel your pain. Will give this a look. Thanks for the write up!

wow, I never imagined building an indexer myself. It looks much harder than I thought. Thanks for sharing your experience! 16384 👏🏻👏🏻👏🏻👏🏻
