Webb24 mars 2024 · Interfaces in Solidity are similar to abstract contracts, but they cannot have any functions implemented. Interfaces are used to define a set of functions that a contract must implement. They are useful for creating contracts that can interact with other contracts in a standardized way. WebbIt's for reporting, and interaction with user interfaces / other services. An Event Handle model is not really suitable on the blockchain, as if an undefined number of handlers can attach to an event, it is hard to judge how much gas triggering the event will end up costing.
