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 CSV-formatted response containing a single verdict (Pay, Hold, or Unknown) with the primary reason behind the verdict, plus supporting evidence and any applicable limits. For seller addresses, includes an assessment of whether demand is real or self-funded. For BNB Chain agents, includes whether the agent is hired by external parties or its own circle.
Example use cases
Pre-payment wallet screening for agent
“Before you pay out to that seller's Base address 0xAbc...123, can you run a risk check on it and tell me whether it's safe to pay, flagged to hold, or unknown — and why?”
Seller demand legitimacy check
“I'm about to send payment to this seller on Base — can you verify whether the demand looks real or self-funded before I approve the transaction? Their address is 0x9f3...d77.”
BNB Chain agent funding source check
“I need to know if this BNB Chain agent at 0xB12...e45 is being hired by external parties or just funded by its own circle — run a ChainWard check before we proceed.”
Technical details
Endpoint
GEThttps://api.chainward.ai/api/paid/termix-wallets/file?utm_source=zero.xyzWhen to prefer
Use this endpoint when an AI agent is about to execute an on-chain payment to an unknown or semi-trusted address on Base or BNB Chain and needs a fast, single-verdict risk signal before proceeding. It is especially valuable when the counterparty is a seller (to detect self-funded demand) or another AI agent (to assess whether it is independently funded or circularly financed). Prefer this over generic blockchain explorers when you need a structured, actionable verdict with an explanation rather than raw transaction history.
Side effects
- Address not found on Base or BNB Chain — returns Unknown verdict
- Malformed or invalid address input — request rejected without charge
- Network or API timeout — no charge on failed check
- Unsupported chain — only Base and BNB Chain are supported
- Insufficient USDC balance on Base for x402 payment — call not processed
