If you choose a chain ID greater than Number.MAX_SAFE_INTEGER for your chain, call me. There's something I'd like to say. Best not in writing

Going all-in on Postgres was the single best decision we made in 2024. Much simpler, with no regression to the quickstart / local dev experience (thanks to PGlite). Obvious in retrospect.

Goal: By the end of 2025, even the largest Ponder app backfills will be fast enough to run in CI. Seconds or minutes, not hours or days. It should feel like a build or reload, not a "backfill".

Ponder 0.9.3 adds a new event ordering strategy designed for low-latency apps that index 10+ chains. The current ordering strategy is “omnichain” - events across all chains share a single queue, with blocks ordered by (block timestamp, chain ID, block number).

Did Etherscan remove their public/unauthenticated tier for API requests? Until recently, you could make unauthenticated requests for verified contract ABIs, contract deployment transactions, etc with a restrictive rate limit (1 req / 5 second). Now seeing consistent "Missing/Invalid API Key" errors.

Quick PG debugging story. And a great blog post about the Postgres null byte situation. Seems to be a common rough edge. https://www.commandprompt.com/blog/null-characters-workarounds-arent-good-enough/ https://warpcast.com/typedarray.eth/0x761b14a8

Fun debugging rabbit hole from this week. Last week, a few Ponder users opened issues for an "invalid byte sequence for encoding "UTF8": 0x00" error. Most software ignores or removes null characters (\0, \x00, or \u0000), but the Postgres TEXT data type rejects them with that error. We reproduced the issue with an ENS NameRegistered event log from 2022 (s/o @greg). Turns out, some EVM event logs contain null characters within decoded `string` parameter values. Now, the framework removes null characters from all decoded ABI parameters before passing them to userland. We could have instead fixed this on the PG driver/Drizzle side, but it seemed more fragile (are we wrong?). We're not certain why this only appeared recently - we haven't changed any relevant codepaths in recent releases. My best guess is that Viem used to remove them but stopped. Viem is a peer dep, so the version can change independently from Ponder's version. PR: https://github.com/ponder-sh/ponder/pull/1414
