This pull request introduces significant changes to the token minting and allowance system by replacing the MintAllowanceUpgradeable contract with a new RateLimitsUpgradeable contract. Additionally, it includes various updates to deployment scripts and contract configurations to align with the new rate limits approach.

Key Changes:

Major Contract Updates:

• Rate Limits Implementation:

  • Replaced MintAllowanceUpgradeable with RateLimitsUpgradeable to manage minting and burning limits more dynamically (src/RateLimitsUpgradeable.sol).
  • Updated Token contract to use RateLimitsUpgradeable instead of MintAllowanceUpgradeable (src/Token.sol). [1] [2] [3]

• Contract Adjustments:

  • Modified various controller contracts (ControllerToken, EthereumControllerToken, GnosisControllerToken, PolygonControllerToken) to use _useMinterLimits instead of _useMintAllowance for checking minting permissions. [1] [2] [3] [4]

Deployment and Configuration Scripts:

• Script Updates:

  • Updated configureToken.s.sol to use LIMIT_CAP instead of MAX_MINT_ALLOWANCE and added new logic for setting rate limits (script/configureToken.s.sol). [1] [2]
  • Added support for Gnosis Mainnet deployment in deployAll.sh (script/deployAll.sh). [1] [2]
  • Updated shell script to use LIMIT_CAP environment variable (script/configureToken.sh).

• Batch Mint Script:

  • Commented out the setMaxMintAllowance and setMintAllowance calls in the batchMint.s.sol script, indicating a shift away from the old allowance system (script/batchMint.s.sol).

These changes collectively enhance the flexibility and security of the token minting process by introducing rate limits and updating the deployment scripts to support the new system.
