in the abi.json ,there has two mint funtion with different params ,i cant call mint function ,show undefined

but in the web3js,it done well

When an ABI is ambiguous you must specify the qualified method name. I.e. contract["mint(uint256)"]. If you don’t need both method, I recommend removing the unnecessary methods from the ABI; it keeps the app size smaller and makes the code easier to read.

I am not sure how web3.js does it, but it may just pick the first one? Ethers makes it a policy to never guess, since that could result in lost funds or otherwise cause problems down the road.

In v6 you will be able to wrap values in a Type object too, which will allow explicitly decisions to be made without having to specify the signature. Coming soon. :)

its erc721 standard，different params remain same function。so just generate the "mint" function, let
me call contract successfully, the contract knows which one to use. but now "mint" function don't exist.i call will show undefined.
so if it exit same function , can you remain one . because in frontend ,it just params different and it just a abi, specific code isn't exit.

Sorry, I don’t quite understand what you are trying to say. :s

If you remove the method you don’t use though, everything will work just fine. Keep in mind the ABI coder is a generic solution, so it shouldn’t make assumptions.

(you only need to remove it from the ABI, not the contract)

i means i need both this "mint" function. they both used to mint token.the different is just one get one param and the other get two param.the contract is supported this way。

if remove one from abi. example. i remove this one

when i enter two params ,it wiil throw error
