[VPD-113]: add NativeTokenGateway compatible with BNB Core pool #8
Conversation
This NativeTokenGateway is compatible with Isolated Pools. It's not compatible with the BNB Chain Core pool. Source: https://github.com/VenusProtocol/isolated-pools/blob/58b76f81f15c61fc441bd1c5b2831509ac943288/contracts/Gateway/NativeTokenGateway.sol

This must be recovered automatically, not hardcoded, depending on the selected network. We can read it from the npm governance package

I would also add (not right now, but ideally before merging the PR) the configurations for the NTG of the Isolated Pools, on the rest of the networks. I would also copy/add the deployment files of those NTG contracts

I would add a number prefix to this deployment script. We won't follow a sequence of execution in this project, but I think it will help to clearly identify the files

I would also consider the original fork tests in the IL repo, to check the NTG works as expected with IL markets

I don't think we should mix tests and no-tests contracts in the same folder. Moreover, can we replace these imports with any configuration in hardhat?

I don't think that we can replace Solidity import statements with Hardhat configuration, as it cannot substitute for actual Solidity imports in the source files.

Should it be renamed to NativeTokenGateway_vWBNB_Core?

the testnet VIP is already executed for this NTG address .

I don't see the dependency. It would be only to rename the deployment, not affecting the deployed code

Do we need two deployment files? Cannot we use only one (taking into account that there will be only on NativeTokenGateway.sol file)

This PR introduces NTG (NativeTokenGateway) for Core pool in bnb chain . NativeTokenGateway contract facilitates interactions with a vToken market for native tokens.
