- of returning
false
on failure. This behavior is nonetheless conventional - and does not conflict with the expectations of ERC20 applications.
-
- Additionally, an {Approval} event is emitted on calls to {transferFrom}.
- This allows applications to reconstruct the allowance for all accounts just
- by listening to said events. Other implementations of the EIP may not emit
- these events, as it isn't required by the specification.
