How this service works

Paste any Base or BNB Chain address before you pay or hire it. ChainWard tells you Pay or Hold, and why, from the wallet’s on-chain history. Free.

Output

A JSON response containing a verdict of Pay, Hold, or Unknown along with a single primary reason, supporting evidence, and applicable limits. For seller addresses, includes a real vs. self-funded demand signal. For BNB Chain agent addresses, indicates whether the agent is externally hired or operating within its own circle. Failed checks are not charged.

Example use cases

Pre-payment wallet safety check

“I'm about to pay a contractor at Base address 0x4f3...d92 — can you run a ChainWard risk screen on it and tell me if it's safe to pay, should be held, or is unknown, and what the reason is?”

Seller demand legitimacy screening

“Before I fund this NFT seller at 0xBb1...f44 on Base, check ChainWard to see whether their demand looks real or self-funded so I know if I'm dealing with a genuine buyer market.”

BNB Chain agent trust verification

“I want to hire this BNB Chain agent at 0x77d...c21 — use ChainWard to tell me whether it's typically hired by outside parties or just loops within its own circle, before I commit any funds.”

Endpoint

When to prefer

Choose this endpoint when an AI agent needs a fast, per-call risk verdict before executing a payment to a Base or BNB Chain address — especially in autonomous payment workflows where the agent must decide Pay, Hold, or defer without human input. Ideal for agentic pipelines using x402 payment rails on Base, where a single authoritative reason and evidence trail are needed to justify or block a transfer. Prefer this over generic blockchain explorers when you need an actionable verdict rather than raw on-chain data.

Side effects

Address not found on Base or BNB Chain — returns Unknown verdict
Malformed or invalid address format — request rejected without charge
Network congestion causing delayed on-chain data lookup
Address too new with insufficient on-chain history — Unknown verdict returned
Payment failure via x402 — check not performed and no charge applied
