Cross chain rebase token

1. A protocol that allow users to depoit tokens into a Vault andin return receive rebase tokens that represent their underlying balance and accrued interest.

   • 10 ETH and accrued 1 reward => Total of 11 rebase tokens. Can redeem these 11 rebase tokens for 11 ETH

2. Rebase token -> balanceOf function is dynamic to show the changing balance with time

   • Balance increases linearly with time
   • mint tokens to our users every time they perform an action (minting, transferring, burning or bridging)

3. Interest rate

   • Individually set an interest rate for each user based on the global interest rate of the protocol at the time user deposits into the vault.
   • This global interest rate can only decrease to incentivise/reward early adopters.
   • Increase user adoption

Caveats

• The admin may grant itself the role to mint and burn rebase tokens, this is a bit centralized part of the contract.
• Let's say a user has two wallets and he has deposited liquidity using both of the wallets. Wallet A has an interest rate of X and wallet B has an interest rate of X - Y. If user tries to move all the funds from A to B, then the final interest rate would become X - Y.
• Let's say a user has a wallet A with an interest rate of X. The global interest rate got changed to something less than X, say X - Y. In this scenario, if user tries to move all funds from wallet A to a brand new wallet B, then the new interest rate of wallet B would become X.
