Get Method Name From A TransactionHash On The Blockchain

[EECvision]

Hi, I want to get the method name that called a function on the blockchain.
e.g. using safeTranferFrom, the method name used to call the function that performed safeTransferFrom is Mint Public. How do I get Mint Public

If you have the ABI, you can use iface.parseTransaction(tx).name to look up the name of the transaction selector from the data, if that helps.

It will only work for calls made directly from the tx selector passed through the data though.

Is that what you mean?

Yes, it is exactly what I mean.

Looking at the screenshot of the section marked Mint Public, It is weird that the method name "Mint Public" is unavailable in the contract abi. How do I get to display that method name "Mint Public"

Thank you for your quick response.

Unless you have the ABI, ethers.js can't directly aid you with this.

If you just have some random tx from the blockchain, you probably wont have it's abi so you can provide the first 4 bytes of call data to the https://www.4byte.directory 's apis to get the suggestions for possible ABIs and then you can decide which to show.

I do this in my project to try to guess a function name (code ref).
