Solana Escrow Program

A secure token swap implementation on Solana blockchain that enables trustless exchanges between two parties (Alice and Bob). The program demonstrates atomic swaps of SPL tokens using an escrow mechanism.

Features

• Atomic token swaps between two parties
• Support for SPL Token and Token-2022 programs
• Secure vault system for holding tokens during the exchange
• Complete test suite demonstrating the escrow workflow

How it Works

1. Initialization: Creates test accounts for Alice and Bob, along with two different token mints (Token A and Token B)

2. Make Offer:

   • Alice creates an escrow offer by specifying:
     • Amount of Token A to offer
     • Amount of Token B wanted in return
   • Tokens are securely locked in a program-controlled vault

3. Take Offer:

   • Bob can accept the offer by providing the requested Token B amount
   • The program atomically swaps:
     • Token A from vault to Bob
     • Token B from Bob to Alice
