"Weird ERC-20 Tokens" is an effort to collect and categorize implementations of ERC-20 tokens with behavior that is surprising or otherwise unexpected.
Given that the ERC-20 specification is so loosely defined there are plenty of token variations out there. One can use this repository to test code against such ERC-20 implementations that don't fully follow the official specification or have potential attack surfaces like reentrant calls, code injection via token name and more.
