Build ponder indexerAgent #164628 files changed
I built the Sworn Indexer, backfilled it against Ethereum mainnet until it reached the chain head, and committed it to
main(8c585f8). Every acceptance number matches the brief. Docker was not available on this machine, so the image anddocker compose uphave not been built or run, and memory during the backfill goes over 512 MB.What the mainnet run returned:
- Rules:
/ruleslists rule 10001 "Early Flock" with the kind, target, window, threshold and registrant in the brief. - Eligibility for rule 10001: 5 and met for
0x887b…, 47 and met for0xe5b1…, 0 and not met for0x84f4…. Each answer lists the blocks and transaction hashes it counted. - Wallet and cards:
0x887b…has card 2 and verified traits 701, 1301 and 1105, plus a fourth, 601./cardslists 15 cards. - Seats: seat 420 has belonged to
0xe5b1…since block 26013599 (2026-09-19) and is still held. - Curator: 19,522 contributors, 28,353 deposits, 41 HourSaved by 33 saviors, and 5,958 deposits by 3,936 contributors in hours 24–65.
- Curator wallet
0x887b…: first-deposit index 95, first deposit in hour 0, 7 deposits, 5 of them in hours 24–65. - Top 32:
/curator/top?n=32returns 32 wallets in descending order. - CORS: every response carries
Access-Control-Allow-Origin. - Restart: after each restart it picked up from the stored block (the last time it caught up 9 blocks in 0.5 s) and did not backfill again.
- Checks:
pnpm install,pnpm codegenandpnpm typecheckpass.
Backfill: about 28 minutes on public RPCs (Tenderly's public gateway and valve.city's demo endpoint), at 500 blocks per getLogs request. Thousands of rate-limit errors were retried automatically with no manual help.
Problems I found and fixed during the run:
- Getting stuck: Tenderly rejects a getLogs request that would return more than 20,000 logs with an error Ponder doesn't recognise, so Ponder retried the same request forever. The default span is now 500 blocks.
- Bad endpoints: blockpi and nownodes return old logs but not old contract state, which stopped the run at rule 10001's read. That read now retries. The README says every RPC URL must be a full archive node; publicnode and flashbots don't work either.
- Patched Ponder: Ponder reserves
/healthfor itself and returns an empty body. A small committed patch (patches/[email protected]) lets the app serve the JSON/healththe brief asks for.
Things you should know before deploying:
- Memory: after the backfill the process runs at about 424–440 MB, which fits your host. During the backfill it peaks at 657 MB, because PGlite alone takes about 300 MB. The Compose file's limit therefore defaults to 768 MB through
MEM_LIMIT. To stay at 512 MB, run the backfill once with the higher limit and then lower it; restarts only catch up. - Docker: add
compose.caddy.ymlto join Caddy's shared network. I kept that out of the main Compose file so a cleandocker compose upworks without that network existing. Postgres on the Docker host is an optionalpostgresprofile. - Deviations from the brief and skill:
- The env file is
env.examplerather than.env.example, because this job may not create.env*files. railway.jsonis included because the brief asks for it, although the reference skill advises against it. It sets no start command, so the Dockerfile's command runs.
- The env file is
- Shared facts: the
shared_facttable is empty because noSharedFactStoredhas been emitted yet.
The README has one section per target and every endpoint with a real mainnet response. It also has one GraphQL query per table and the SQL examples.
