Smart Contract Address Risk Scanner

Read a deployed contract's bytecode and report the powers it holds — upgradeability through EIP-1967 proxy slots, self-destruct, mint, pause and ownership transfer. Findings describe what the contract CAN do rather than pronouncing it safe or unsafe: an upgradeable proxy is a trust assumption whose weight depends on who holds the admin key, and bytecode cannot tell you that. The opcode scan walks PUSH data so that bytes inside address literals are never mistaken for instructions.

Authorized, defensive use only. Check assets you own or lawfully public data. This tool is educational and never provides another party's private data.

Reads a deployed contract’s bytecode from public chain data and reports the powers it holds — upgradeability, self-destruct, mint, pause, ownership transfer.

These are powers, not verdicts. An upgradeable proxy is a trust assumption whose weight depends on who holds the admin key — a multisig with a timelock is a very different proposition from one private key, and bytecode cannot tell you which it is. Nothing here says a contract is safe.

A public EVM contract address.

What happens to what you enter

  • The analysis runs on Solvex servers. What is recorded afterwards is a SHA-256 hash of your input and a coarse summary of the outcome — never the input itself, and never a result you could be identified from.
  • Tools that read public sources (certificate logs, DNS, a public chain) contact those sources from our servers through a fetcher that refuses private and internal addresses.
  • An email address is stored only where a tool offers to send you a report and you choose to give one.

Limits: ten runs of this tool per minute from one address, and three signed reports per minute. Past that the tool says so and tells you when to try again.

When a free check is not enough

This tool reads what is public and reports what it can see. The Smart Contract Security Audit engagement is the authorized, specialist-led version: signed scope, findings proven by hand, a signed report, and a retest.
