Contract powers check before an agent signs

● verified · data.onchain · 0.02 USDC/call · base

Before you sign or approve: can this Base contract be paused, frozen, or have new tokens minted by its owner? Can it self-destruct or delegate execution somewhere you have not seen? Returns the opcodes and function selectors actually present in the deployed bytecode, resolves EIP-1967, UUPS, transparent, minimal-proxy and EIP-7702 delegated accounts to the implementation that really runs, and states the RPC trust level behind every answer. This is factual capability evidence for your own policy. It does not label a contract safe, malicious, or exploitable, and every response says so.

Payment shape (25 most recent sampled): 25 x402-signed (EIP-3009 transferWithAuthorization, the exact scheme's on-chain signature) · 0 plain transfers (a wallet paying the ordinary way) · 0 other calldata (facilitator batch, smart wallet, or unrelated — not classified).

Peak day 2026-09-12: 3 payments. Last indexed day 2026-10-07: 1. Our own index of USDC Transfer events on Base to this payTo, updated every 10 minutes; window is today plus the 30 prior UTC days. Base USDC only — a seller settling elsewhere reads as quiet here. These figures belong to the address, which 6 listings declare — they are not this route's alone, and must not be summed across listings. Methodology.
