Decode Smart Contract Call Data

Learn how to decode encoded smart contract function calls using the Okto SDK in Unity.

Overview

The Okto SDK provides decoding function that allow you to interpret encoded smart contract function calls.

Decoding is the reverse process of encoding - it takes hex-encoded call data and converts it back into readable function names and parameters using the contract's ABI.
