Oko contract explorer

What is Oko?

Oko is an Ethereum explorer focused on smart contracts.
It is intended for a public of experienced Ethereum developers. It was developed to fill a gap in the tools available out there that wouldn't show enough information about smart contracts.

Oko tries to get the source & ABI of verified contracts, and uses Panoramix to decompile contracts without code.
It also tries to interpret the input data for all calls made to contracts, to display it in an understandable form.

How do I use it?

Simply use the search box above. You can enter:

- A contract address
to see source code or decompilation of a contract, calls made from/to it.
- A transaction hash
to see the state modification caused by the transaction, and a tree of the calls made during it.
- A block number
to see basic information about the block, and a list of transactions included in it.

Last block is 23970046.

You can also simulate arbitrary calls.
