OverviewERC-165 is an interface identification mechanism that enhances compossibility as contracts can determine whether a contract supports an interface at compile time.ERC-165 GoalPrior to ERC-165, there was no mechanism to check whether a contract supported a specific interface, such as ERC-20. Therefore, there was no way of verifying whether a contract could accept tokens or tokens sent to a contract would be ‘stuck’ and effectively lost.ImplementationERC-165 introduces a standardized fun...
