Instructions

Clone the repo, and add your Private Key (Base58 string) and RPC to the config.py.

When swapping, you must use the pool id, also known as the pair address. Do not use the mint aka token address.

We cannot pass the mint directly because there can be several pools for a single mint.

It is up to the user to fetch the pool ids via the Raydium API or via RPC methods I've included.

FAQS

What format should my private key be in?

The private key should be in the base58 string format, not bytes.

Why are my transactions being dropped?

You get what you pay for. Don't use the main-net RPC, just spend the money for Helius or Quick Node.

How do I change the fee?

Modify the UNIT_BUDGET and UNIT_PRICE in the config.py.

Why is this failing for USDC pairs?

This code only works for SOL pairs.

Why are there "no pool keys found"?

Free tier RPCs do not permit GET_PROGRAM_ACCOUNTS()! You must use a paid RPC.

Does this code work on devnet?

No.
