Approve and Transfer script for SPL 2022 tokens

This script demonstrates a simple flow:

• Investor approves a delegate (third party) to spend tokens from their token account.
• Third party performs a transfer using the transfer hook instruction.

Setup

1. Copy .env.example to .env and fill the values (mint address, program ids, RPC_URL, token account addresses or leave blank to derive associated addresses).
2. Place JSON keypair files in the same directory: investor-keypair.json and third-party-keypair.json (each file contains the secret key array produced by Keypair.toSecretKey() / fs.writeFileSync(..., JSON.stringify([...secretKey]))).
3. Install dependencies:

npm install

Run

npm start

Notes

• This script assumes holder/group/holdergroup/security-associated accounts and transfer rule exist on-chain for the token. It only performs approve + delegated transfer.
• Replace placeholder key files with real secret key arrays. Do not commit real secrets to source control.
