+While it is useful to represent the token in bank module, enabling the token to be in action in evm environment is very convenient and pave the possibility of integrating new features into the ecosystem.
 
 Each token can be enabled to work in the evm environment by the token manager, which means user can interact with the token through evm side like metamask or anyother evm wallet and more other protocol integrated in the future. Note that, token manager can disable or enable the token to be used in the evm environment.

 By setting `allow_new_fuctionalities`, `issuer` can specify whether they accept new functionalities or not when creating a new token. If he permits it, when upgrading the chain, the new features will be automatically added to the `functionalities_list`and the `manager` can then modify the `functionalities_list` as he sees fit. Otherwise, the `manager` can not chaing the `functionalities_list`.

 ## Details
 
 - AllowFunctionalities: list of functionalities that the module provides. They can be update after the chain upgrade to enable new functionality add-on to the module.
+- RatelimitDuration: duration of ratelimit for `mint` functionality.
 - WhitelistAddresses: list of the address that's allow to create new token.
