Stock Token Program

Overview

This is a proof of concept transfer-hook program that exibits the power of token extensions for interesting mechanics. It ensures token transfers occur only during market hours and validates the state of token accounts before processing transfers. The program also manages additional account metadata necessary for these operations.

Key Functions

1. Token Transfer Execution:

   • Validates that token accounts are in a "transferring" state.
   • Ensures transfers only occur during market hours (9:30 AM to 4:00 PM ET, Monday to Friday).
   • Executes the token transfer if conditions are met.

2. Account Metadata Management:

   • Initializes and updates extra metadata for token accounts.
   • Ensures metadata is associated correctly with the respective token mint and authority.

Utilities

The program includes utility functions to:

• Determine daylight saving time.
• Convert UTC to Eastern Time.
• Find specific weekdays in a given month.
• Check if the current time falls within market hours.

Error Handling

Handles various errors related to transfer operations and market conditions, such as:

• Attempts to transfer outside market hours.
• Invalid seeds or missing signatures.
