Diffing

You can use the diffing utility to generate the diff between two contracts.

sh diff.sh <pathA> <pathB> <outName>

If one of the contracts is deployed you can download the contract from etherscan via make download address=0x...

For a mainnet v2 listing you might want to diff the a/s/v implementations, with a standard implementation (like e.g. the ones of DAI) to ensure it's correct.

# LUSD vs DAI diff example
make download address=0x7b2a3cf972c3193f26cdec6217d27379b6417bd0 # aDAI impl
make download address=0xB2f4Fb41F01CdeF7c10F0e8aFbeB3cFA79d1686F # aLUSD impl

# generate aTokenDiff via
sh ./diff.sh ./etherscan/0x7b2a3cf972c3193f26cdec6217d27379b6417bd0 ./etherscan/0xB2f4Fb41F01CdeF7c10F0e8aFbeB3cFA79d1686F aLUSDimplDiff

# If the code is only available with flattened format you would need to bring the contracts in a similar format.
# You can do so by flattening the respective contract.
# In the example case of LUSD and DAI where both are verified via json this method should not be used.
