I've found several contracts for which I am able to call functions on the contract's front-end but that exist in neither the contract source code nor ABI.
When I call the functions, ftmscan (an analog of etherscan) shows the function name, but when I go the contract page to view the source code and ABI, no trace of the function can be found.
How is this possible?
If I manually modify the ABI to include the function, would I be able to call the function without using the front-end, using, for e.g. the web3 python package?
