What is ABI Encoder?

When you want to verify your Solidity Smart Contract's code on EtherScan, BscScan, PolygonScan, etc., or manually make a transaction to call your contract's method, you need to encode input arguments in a special way.
ABI Encoding Service helps you to encode these arguments.

How does it work?

You can use the auto-parse section. Just copy your ABI json interface to an input field and click a ‘Parse’ button. After that, all the necessary parameters will appear. Insert values and get the result.
Also, you can manually construct your object using the manual section.

HashEx offers a free ABI decoder online service that allows you to encode your contract’s arguments.

ABI itself is the description of the code interface. It’s a way for the contracts to interact within an ecosystem as well as contract-to-contract.

Smart contract ABI parsing is required for verifying the contract on Etherscan or making a transaction to call a method. For most actions regarding this code, you would require a special tool, and the arguments have to be encoded in a specific way. HashEx tool does it automatically, free, and doesn’t involve downloading any extra applications.

Code itself is used in the byte format, so it’s harder to decode it correctly. For easy interactions with said code, HashEx has created its ABI decoder. An additional tool allows you to manually enter the values for the parameters.
