For some reasons I am having a lot of diffs in bytecodeHash while nothing has been changed.
Is the dev branch updated?

What is the motivation for removing these?

It is in the description of this PR but in a nutshell
- incompatibility with chain not using ETH as base token
- confuse some explorers

@vladbochok any additional info you need ? |
|
@vladbochok any advices on how to update the SystemContractsHashes file properly? |
@thomas-nguy you should be able to merge in dev, take any of the changes (this will be overwritten), and then run |

@koloz193 Thanks, I have rebased and updated the file I am ending having a lot of differences, perhaps the file in the dev branch is outdated? |

What ❔
Remove Name, Symbol and Decimal from L2BaseToken.sol
Why ❔
Multiple issues with those methods :
1- For hyperchains that does not use ETH as base token, the values returned by those methods are wrong so it should not be hardcoded. I couldnt find a good way to make them variable without heavy changes on the initialisation process
2- L2BaseToken IS not an ERC20 as it does not implement IERC20 interface (no approval or allowance) but it looks like it which confuse some explorers
One example is on https://era.zksync.network/
The value of ETH is counted twices as it is also recorded as an ERC20
https://era.zksync.network/address/0xd0c511bdbf219e3d5793e47b9ad559c9f69b3404
We should remove all confusion and make "symbol" and "name" agnostics as it is done on Ethereum
