JavaScript Raydium AMM V4 Log Decoder

Overview

JavaScript (nodejs) wrapper around Raydium AMM V4 Rust SDK for decoding Solana transaction logs containing a ray_log.

Ability to decode:

• Raydium swap logs: swap amount in, swap amount out, swap direction.
• Raydium liquidity add logs: SOL amount in, coin amount in, token decimals.

How to use:

• Run npm install inside /node_call.
• Run cargo build inside /program.
• node_call/index.js contains JavaScript functions for decoding Raydium logs.
• program/src/main.rs calls the respective decode functions natively.
• Example usage: decode_ray_log_swap_amount_in('<RAY_LOG HERE>');, more examples provided in index.js.
• Ability to export log decoding functions to outside JS files, use absolute path for this, instructions in index.js.

Additional Notes:

• The wrapper does not have error checking, functions with "swap" must have a Raydium "swap" log as input and functions with "init" must have a Raydium "init"/"lp add" log as input.
