Base Contract Capability Inspector

Live selected bytecode signals, common-proxy resolution, and evidence provenance on Base mainnet.

Choose a sample or enter a Base address, then run a live analysis. No request runs on page load, including shared address links. Current availability is published on the status page.

Public preview by default. Allowlisted samples return full demo responses; arbitrary addresses may return a limited preview.

What a response tells you

Illustrative response excerpt — not live chain evidence, not an audit of the address above. Use the live button to request an actual observation.

  "audit": {
    "dissection": { "opcodesDetected": ["DELEGATECALL"] },

An observed capability is not a safety verdict. Full responses add bytecode hashes, supported proxy resolution, source provenance and limitations. Learn how to interpret them.
