# Solana Scripts

This is a library of Rust scripts for specific purposes:

- [Generate a new wallet](#new-wallet)
- [Create an SPL token](#create-an-spl-token)
- [Mint an SPL token](#mint-spl-tokens)
- [Get an associated token balance](#get-token-balance)
- [Get the creation date of an account](#get-account-creation-timestamp)
- [Get the owner of an NFT](#get-nft-owner)
- [List NFTs in wallet](#list-nfts-in-wallet)
- [Subscribe to events](#subscribe-to-events)
- [Fetch onchain Anchor IDL](#fetch-onchain-anchor-idl)

The scripts are found in the `src/bin` folder. They can be configured using environment variables, which are documented below.
