No source code required.

Online

Free to use. No wallet connection needed.

Building a pipeline?Get API access

Decompiled output is a best-effort reconstruction. Always verify against on-chain behaviour.

Runtime bytecode

Start with a deployed address or paste raw EVM bytecode.

Readable Solidity

Recover function bodies and structured control flow.

Selector recovery

Resolve function selectors to understand entry points.

Unverified contracts

Inspect the logic without published source or an ABI.

Decompiler API

From one contract to your whole workflow.

Automate your research with the same decompiler, through a simple REST API. Choose a monthly plan or buy credits as you go.

Talk to our team
What counts as one API call?

Each decompilation request — by contract address or by raw bytecode — counts as one call, regardless of contract size.

Which chains are supported?

Ethereum mainnet and BNB Chain. The API resolves bytecode on-chain by address, or you can submit runtime bytecode directly.

What does the API return?

A JSON payload with the reconstructed Solidity-like source plus every artifact the engine emits, the same output shown in the web UI's result panel.

How do I get an API key?

Buy one in our Telegram bot — pay with USDT or USDC on Ethereum or BNB Chain and the key is delivered in chat as soon as the on-chain payment confirms, usually within a minute. Credit packs and monthly subscriptions are both available; for Enterprise volume, email [email protected].

Do prepaid credits expire?

No. Credit packs are pay-as-you-go with no commitment and never expire. Subscriptions renew monthly with a fresh call allowance.
