Trying to match a deposit against a transfer event

[michprev]

While EIP-20 guarantees to emit the Transfer event, it seems like an unnecessary logic that can bring more problems. What if there are multiple Transfer events? Or none at all (because of a non-standard ERC20 token). Multiple deposits per transaction should be supported. How will work pairing these events, then? If there is any necessary information missing in deposit events, it should be included directly in the deposit events.
