ABI Decode Tool
Use this ABI decode tool to decode hex-encoded EVM data into readable Solidity values based on the types you provide.
Example Usage
- Decode return data from a contract call using known output types.
- Inspect a stored payload or log fragment while debugging a frontend.
- Turn ABI-encoded hex back into readable values for comparison.
ABI Decode Tool Explained
An ABI decode tool takes hex-encoded EVM data and interprets it using the Solidity types you specify. This is useful when you are inspecting contract return data, debugging stored payloads, reading encoded parameters, or comparing results from frontend code and scripts. Instead of treating the data as an unreadable hex string, you can map it back into addresses, integers, strings, arrays, and other Solidity values. This makes low-level contract debugging much faster, especially when you want to verify that a payload or response matches the types you expected.
FAQ
Do I need the exact types to decode correctly?
Yes. ABI decoding depends on the correct ordered list of Solidity types.
Can I use this for contract return data?
Yes. It works well for decoding outputs when you already know the expected output types.
Why are big integers shown as strings?
Because JavaScript numbers are not safe for many large EVM integers, so strings preserve the full value.
