TokenManagerHelper2

These smart contracts are designed for creating new tokens and executing trades.
The old TokenManager (referred to as V1) still functions for trading tokens that have already been created but cannot create new tokens; It is only used to support the buying and selling of tokens created before the TokenManager2 (referred to as V2) deployment.
If full support four.meme is needed, both TokenManager V1 and V2 should be supported.
If you only wish to support tokens created after September 5, 2024, then only V2 TokenManager needs to be supported.
The method for simultaneously supporting both V1 and V2 TokenManagers is as follows:
- First, use the TokenManagerHelper method getTokenInfo to get the token information.
- Check information if the token was created by V1 that the tradings should be processed through the interfaces of old V1 TokenManager. Otherwise, use the V2 version.
- If pre-calculations of trading are needed, call helper methods.

This smart contract is a wrapper of the TokenManagers. It is designed for getting token information and performing pre-calculations easily.
The old TokenManagerHelper (referred to as V1) still works but we have provided a new TokenManagerHelper2 (referred to as V2) contract that unifies the information query interfaces for both V1 TokenManager and V2 TokenManager.
We recommend users who have previously used V1 helper to migrate to V2 helper.

This smart contract is mainly used to create new tokens and execute trades.
