Payment agent security · Blockscout data
Before your AI agent pays, ScoutGuard checks the chain.
Blockscout-powered transaction intelligence for autonomous EVM payments. Inspect recipient history, identify address-poisoning risks, validate supported assets, and enforce payment policy before signing.
did you think they have
forgotten, about
your agents?
Autonomous AI agents execute payments without human eyes. Malicious vanity addresses seed transaction histories, matching both ends of trusted vendors. ScoutGuard PRO checks Blockscout sender history, recipient reputation, contract verification, and payment policy before an agent signs ETH or allowlisted USDC. The live check makes fresh provider requests; saved investigations and simulations are separately labeled below.
Blocks when required Blockscout data is unavailable. Source verification is a signal, not a security audit.
Try a Real Security Evaluation
Submit a proposed payment. ScoutGuard reads live Ethereum data and builds the comparison set from the sender's recent outbound history. No transaction is signed or broadcast.
Evidence appears here
Run a check to see the decision, live Blockscout data, recent sender-history comparison count, receipt digest, and exact Explorer address pages. An address page proves the address data source, not that a proposed payment happened.
A past transfer event link appears when Blockscout returns a transaction containing an outbound transfer between these addresses. The transaction's initiator may differ from the transfer sender. It does not prove this proposed payment occurred. ScoutGuard does not broadcast transactions.
Unkeyed SHA-256 digest (not a signature):
Watch the investigation unfold.
These saved, sanitized results came from completed Blockscout-backed checks on 23 October 2026. Playback reads a local record only. It makes no new Blockscout request.

Inspect saved Blockscout evidence and provenance
The downloadable file is a sanitized receipt excerpt transcribed from the saved observation. The original receipt ID and exact API timestamp were not retained. Its unkeyed SHA-256 digest is not an authenticated Blockscout signature.
Attack Specimens & Pre-Flight Oracle
Select a labeled simulation. Each case runs through the same policy engine with fixture data so the decision is reproducible.

Server-side ethers example for a real USDC transfer flow. Replace the wallet inputs with your own; this page never signs.
A documented address-poisoning attempt
The Poison-Hunter research sample identifies a look-alike address that sent a tiny USDT transfer to a victim. Blockscout shows the historical transaction. Replay its published addresses through ScoutGuard's current similarity rule to see the pre-signing decision it would give with the original counterparty reference available.
