Secudity Tools

Pick the right checker for the risk in front of you — txs, repos, signatures, approvals, or upgradeable contracts.

Decode Ethereum transactions and raw calldata into function calls, logs, and token transfers.

Use when you have a tx hash or calldata hex

Scan a GitHub URL or package.json for interview-scam malware hooks, shady deps, and install scripts.

Use before cloning a “test assignment” or collaboration repo

List active ERC-20 / NFT approvals for any wallet and jump to revoke flows.

Use after phishing or to audit unlimited allowances

Explain Permit, Permit2, and custom typed-data payloads before you sign.

Use when MetaMask asks to “Sign typed data” / Permit

Detect EIP-1967 / UUPS / beacon / minimal proxies and reveal implementation + admin.

Use before auditing or integrating an upgradeable contract

Reveal the real registrable domain and flag brand lookalikes like streamyard.com-call.live.

Use when a meeting, login, or “support” link looks slightly off

These tools are read-only helpers. They do not replace a professional audit — and they never ask for your seed phrase.
