Solana Indexer

Overview

The Solana Indexer is a Go-based application designed to track the creation of new coins on Pumpfun and the migration of assets from Pumpfun to Raydium. By utilizing the Yellowstone gRPC service application monitors transactions in real time and stores relevant data in MongoDB for efficient querying and analysis.

The entire application is dockerized, enabling seamless setup and deployment for developers and teams.

Requirements

Docker installed on your machine
Access to a gRPC Solana endpoint for transaction monitoring

Setup

To get started with the Solana Indexer, follow the configuration steps outlined below:

Configuration

Before running the application, configure your environment by editing the .env file with the following settings:

MONGO_DB_NAME=solanaIndexer
MONGO_USERNAME=example1
MONGO_PASSWORD=example2
GRPC=grpcEndpoint

MONGO_DB_NAME: The name of the MongoDB database to store indexed data.
MONGO_USERNAME: The MongoDB username for database access.
MONGO_PASSWORD: The MongoDB password for secure access.
GRPC: The Solana gRPC endpoint for monitoring transactions in real time.

Running the Application

Once the .env file is properly configured, you can start the Solana Indexer application using Docker. Simply run the following command to build and launch the container:

docker-compose up

This will build the Docker image, pull any necessary dependencies, and start the application.

Upon startup, the application will simultaneously monitor both of the things:

New coin creations on Pumpfun
Migrations from Pumpfun to Raydium

Database structure

Pumpfun created coin structure in database

type PumpfunCoin struct {
	ID                     primitive.ObjectID `bson:"_id,omitempty"`
	CreatedAt              string             `bson:"createdAt"`
	CoinAddress            string             `bson:"coinAddress"`
	Creator                string             `bson:"creator"`
	BondingCurve           string             `bson:"bondingCurve"`
	AssociatedBondingCurve string             `bson:"associatedBondingCurve"`
	Block                  uint64             `bson:"block"`
	Signature              string             `bson:"signature"`
}

Raydium migrated coin structure in database

type RaydiumCoin struct {
	ID          primitive.ObjectID `bson:"_id,omitempty"`
	MigratedAt  string             `bson:"migratedAt"`
	CoinAddress string             `bson:"coinAddress"`
	PoolId      string             `bson:"poolId"`
	Pool1       string             `bson:"pool1"`
	Pool2       string             `bson:"pool2"`
	Block       uint64             `bson:"block"`
	Signature   string             `bson:"signature"`
}
