Write your indexing logic once, and Ponder will use it to process raw logs from multiple chains. If you happen to need chain-specific logic, you can write if (context .network.chainId === 1) { ... } Excited to see what else people build with multi-chain indexing

`eth_getLogs` requests that specify a blockHash should cost fewer RPC credits than requests using fromBlock/toBlock it's a constant vs linear compute/io cost for the node (see reth implementation here)

Ponder is built for application developers. Your code runs in a JavaScript runtime (Node.js) where you can import NPM packages and make network requests. It’s easy to do things that are painful in environments like WebAssembly sandboxes, SQL engines, and EVM runtimes

Ponder used to be plagued by database-specific bugs. Now, the tests run against both SQLite and Postgres ("database" is a GH Action matrix variable) IMO, mocking the db is a trap. If you want stability, run tests against the same db software that's used in prod

Kent C. Dodds 🌌

@kentcdodds

Using SQLite gives you superpowers in so many ways. Testing is one of them. Even your lower-level tests can run against a real database with no mocking necessary (using their own instance or even an in-memory version). And they're still *very* fast. So cool.

Solidity events should never have been called events - They cannot be "handled" onchain; contracts are not actually event emitters - They cost gas and are stored forever - The opcodes are LOG{0-4} - JSON-RPC methods use "log" They're (typed) logs. They should be called... logs

@GalloDaSballo eth_getLogs({ topics: [ keccak256("Upgraded(indexed string)"), implementation_address ] }) Assumes you only care about EIP-1967 compliant proxies. Use an RPC provider that has no limit on eth_getLogs block ranges. Alchemy Composer is great for this kind of task.

TIL 1) An eth_getLogs request to a Nethermind node for a pruned block range returns []. I was expecting an error. 2) An eth_getLogs request to Ankr's public RPC returns [] if the target log has topics = ["0xa"] and you specify ["0xa", null]. I think this is a bug?

@sammdec @ponder_sh Great question. At the moment, no - you would need to fetch the entire list and get the length client-side. Though, we are working towards making the API layer fully customizable, so you can write typescript route handlers that query the indexed database directly.
