How this service works
Verdix standard ($0.10): call before larger or repeated payments to an EVM address on Base, when an address-age read is not enough. Sanctions, scam/phishing lists, address poisoning and contract/deployer signals, plus on-chain behaviour analysis. Returns safe/caution/danger with reasons.
Output
A JSON response containing a verdict of 'safe', 'caution', or 'danger', along with signals derived from OFAC sanctions databases, known scam/blacklist sources, and on-chain transfer history and activity pattern analysis for the queried Base address.
Example use cases
Pre-transfer compliance check for DeFi payout
“I'm about to send a batch of USDC payouts on Base — can you run a standard risk screen on 0xAb5801a7D398351b8bE11C439e05C5B3259aeC9b before I release the funds to make sure it's not sanctioned or flagged?”
Agent vetting a new counterparty wallet
“A new supplier just gave me their Base wallet address 0x1234567890abcdef1234567890abcdef12345678 — do a standard Verdix screen on it before I approve them as a payout recipient.”
Automated fraud check in payment pipeline
“As part of my automated payment workflow on Base, screen the destination address 0xdAC17F958D2ee523a2206206994597C13D831ec7 for OFAC hits, scam listings, and suspicious on-chain activity before the transaction fires.”

Choose the standard tier when you need deeper analysis than the quick tier (which is faster but shallower) but don't require the most exhaustive possible investigation the deep tier provides. Ideal for regular automated agent workflows where moderate latency is acceptable and a balance of thoroughness and cost ($0.10/call) is appropriate — such as screening counterparty or payout addresses before mid-value transfers on Base.
Side effects
- Invalid address format (not a valid 0x… EVM address) — validation error returned
- Chain other than 'base' specified — rejected, only Base is supported
- Address not yet on-chain or has zero history — may return limited signals with a safe default
- Payment failure (x402 protocol) — call blocked if USDC payment not processed
- Upstream data source unavailability — may degrade verdict accuracy or return an error
