HashEx ABI Encoder
According to the abi-spec:
Constructor and fallback function never have `name` or `outputs`
but the ABI example defines a constructor with name of empty string:
"type": "constructor",
"name": "",
The name value should be null or the name key should not be present at all.
The calculation of function selector seems to be wrong.
Error(string) for abiencoder returns 5e8a70b4. It should return 08c379a0
Panic(uint256) for abiencoder returns 08754fa9. It should return 4e487b71
Hi,
I would like to encode an ABI without any parameters but when I click in parse option it doesn't parse the object
Any help is appreciated.
Thanks
uint is uint256
Given a parameters which is an array of tuple the encoding function produces a wrong result due to input restrictions.
The input field should enforce the user to enter something like this [[1,2,3,4],[5,6,7,8]]
but it only takes in the values for one tuple.
This results in a wrong abi encoding for the function.

Hello there,
This tool helps me a lot,
I wanna know how to encode a function which has a variable of structure type.
Thank you.
My contract constructor arguments has include uint256[3] feeSettings
,then I copied form remix abi json and exactly fill every parameter. I copied generated abi code string, but I can not verify my contract.
I did it twice and check every step, but the same result. So I to find only this type argument does not show the right type,I created another contract and remove this type,the part of uint256[3] feeSettings
using hard-coding, Wow,it is fine.
So I'm be sure contain argument such as uint256[M]
type generate wrong abi encoding.
I hope you can fix it as soon as possible!
Seems to be a glitch in the code, but after inputing parsed JSON file for ABI w/ constructor arguments, no encoding output is generated. Infact, the encoding generator doesn't have any output for you to copy at all. I tried Edge and Firefox, and used Linux and Windows.
and also array of tuples
Here's the abi:verifier.abi
The method id for verifyTx should be 0x43cd76fc while the online encoder gave me 0xc7f48250.
And also my input is:
[
[
"0x0e80ca8906f6387652a94c97d79c2446708417437743b76b47b567c3e0f6faee",

The correct encoded input should be:
