THE PROBLEM

Complex calls.
Clear answers.

A contract prompt can hide the details that matter most. KEVO turns raw calldata and on-chain evidence into a readable inspection, so you can see what a call requests and what remains unknown.

BUILT FOR THE MOMENT BEFORE YOU SIGN
WHAT YOU CAN INSPECT

See the intent.
Keep the context.

One focused workspace for the first questions you should ask of an EVM call.

01 / DECODE

Understand the call

Read ERC-20 transfers and approvals in plain language. Bring an ABI to decode other function arguments.

FUNCTION + ARGUMENTS
02 / PERMISSIONS

Spot access requests

See the spender, requested allowance, and exact maximum-value approvals without treating a request as an executed transfer.

ALLOWANCE CONTEXT
03 / EVIDENCE

Check the contract

Confirm whether code is deployed on Ethereum or Base. View explorer metadata when the API is configured.

ON-CHAIN BYTECODE
KEVO WORKSPACE

Inspect before
you interact.
