Mango Events Parser

This is a Node TypeScript repository for parsing Mango events from transactions on Solana mainnet using the Mango program account ID: 4MangoMjqJ2firMokCjjGgoK8d4MXcrgL7XJaL3w6fVg.

Installation

git clone https://github.com/ritvick/mangosolana.git

Usage

docker compose -f docker-compose.development.yml up

This will bring the docker up and program will do the following:

The application will establish a connection to Solana mainnet via an RPC endpoint.
The application will query transactions from Mango's program account and try to decode and parse for any available Mango events in each transaction's logs.
If an event is found, the parsed data along with the transaction signature and block time will be logged to the console.
