# This approach uses a particular event emitted once very early to trigger token registry
|
|
# initialization. It is not so important what the event is but rather that it was emitted before
|
|
# any other event of an ERC20 token. We even don't know what contract it is. Besides that, the ABI
|
|
# file for that contract was inferred since no contract information or source code is available
|

# out there.
