🔁 Cross-Chain Rebase Token Protocol

This project implements a Cross-Chain Rebase Token Protocol where users can deposit assets into a vault and receive dynamic, interest-accruing tokens in return. These rebase tokens automatically reflect yield over time and enable seamless cross-chain interactions.

🔧 Key Features

⛏️ 1. Vault-Based Deposits

• Users deposit assets into a secure vault.
• In return, they receive rebase tokens representing their deposit.

📈 2. Rebase Token with Dynamic Balance

• The balanceOf() function is dynamic:
  • Token balance increases linearly over time.
  • Rebase occurs automatically on every action:
    • Minting
    • Burning
    • Transferring
    • Bridging

💰 3. Interest Accrual per User

• Each user has a personalized interest rate fixed at the time of deposit.
• The interest is calculated based on a global protocol interest rate.
• The global rate is designed to only decrease over time:
  • Early adopters benefit more.
  • Incentivizes early participation and adoption.

🧠 How It Works

1. Deposit into Vault

   • Users deposit approved assets into the protocol vault.

2. Mint Rebase Tokens

   • Protocol mints rebase tokens to user address.
   • Initial balance is proportional to the deposit value.

3. Interest Calculation

   • Each user’s balance increases linearly using their fixed interest rate.
   • The balance increases without needing manual claims.

4. Bridging Across Chains

   • The rebase token is designed for cross-chain compatibility.
   • Rebase logic ensures consistent balance on any supported chain.
