Agents.fun Base indexer

A Ponder indexer for tracking Memeorr contract events and building a GraphQL API.

Overview

This indexer tracks the following Memeorr events:

  • Collected
  • Hearted
  • OLASJourneyToAscendance
  • Purged
  • Summoned
  • Unleashed
  • FeesCollected

The indexed data is exposed via a GraphQL API that can be queried to analyze Memeorr activity.

Docker Deployment (development)

Deploying will Docker will run the indexer in development, inside a containerized environment, alongside a PostgreSQL database.

  1. Create a .env file following the .env.example template.
  2. Start the Docker container:
docker-compose -f docker-compose.dev.yml up

The GraphQL playground will be available at http://localhost:42069/graphql

Local Development

  1. Clone the repository
  2. Install dependencies:
npm install
  1. Create a .env.local file with your RPC URL:
PONDER_RPC_URL_8453="https://eth-mainnet.g.alchemy.com/v2/YOUR-API-KEY"
  1. Start the development server:
npm run dev

The GraphQL playground will be available at http://localhost:42069/graphql

Deploy

Check out the ponder deployment guide for detailed instructions.

Useful queries for testing:

Run ponder on one port:

 npm run dev

Query all summon events and format:

curl -X POST http://localhost:42069/graphql \
  -H "Content-Type: application/json" \
  -d '{
    "query": "query { summonEvents { items { id chain summoner memeToken memeNonce nativeTokenContributed timestamp blockNumber } } }"
  }' | awk '
  BEGIN { indent = 0 }
  {
    gsub(",", ",\n", $0);
    gsub("{", "{\n", $0);
    gsub("}", "\n}", $0);
    gsub(":", ": ", $0);
    for (i = 1; i <= length($0); i++) {
      char = substr($0, i, 1);
      if (char == "{") { print char; indent += 2 }
      else if (char == "}") { indent -= 2; printf("%*s%s\n", indent, "", char) }
      else if (char == ",") { print char; printf("%*s", indent, "") }
      else printf("%s", char)
    }
  }'

Query all tokens and format:

 curl -X POST http://localhost:42069/graphql \
  -H "Content-Type: application/json" \
  -d '{
    "query": "query { memeTokens { items { id chain owner memeToken memeNonce name symbol decimals lpPairAddress lpTokenId liquidity heartCount heartAmount isUnleashed timestamp blockNumber } } }"
  }' | awk '
  BEGIN { indent = 0 }
  {
    gsub(",", ",\n", $0);
    gsub("{", "{\n", $0);
    gsub("}", "\n}", $0);
    gsub(":", ": ", $0);
    for (i = 1; i <= length($0); i++) {
      char = substr($0, i, 1);
      if (char == "{") { print char; indent += 2 }
      else if (char == "}") { indent -= 2; printf("%*s%s\n", indent, "", char) }
      else if (char == ",") { print char; printf("%*s", indent, "") }
      else printf("%s", char)
    }
  }'
