Cross-chain Rebase Token

1. Create protocol that allows users to deposit into a vault and return, receiver rebase tokens that represent their underlying balance.
2. Rebase token -> balance of function is dynamic to show the changing increasing balance with time.
   • Balance increase linearly with the time
   • Mint tokens to our users every time they perform an action (minting, burning, transferring, or... bridging)
3. Interest rate
   • Individually set an interest rate or each user based on some global interest rate of the protocol at the time the user deposits into the vault.
   • This global interest rate can only decrease to incentive/reward early adopters.
   • Increase token adoption.
