How this service works
Verdix deep ($0.50): call before large or first-time payments to an EVM address on Base when your policy asks for the top tier. Same full check set as standard: sanctions, scam/phishing lists, address poisoning, contract/deployer signals, on-chain behaviour. Returns safe/caution/danger with reasons.
Output
Returns a verdict of 'safe', 'caution', or 'danger' for the screened address, backed by OFAC sanctions database checks, known scam and blacklist database lookups, and deep on-chain behaviour analysis including transfer history and activity patterns. A 'safe' verdict means no risk signals were detected but is not an absolute guarantee.
Example use cases
Autonomous agent vetting a payout address
“I'm about to pay out a freelancer at 0x742d35Cc6634C0532925a3b844Bc454e4438f44e on Base — can you run a deep risk screen on that address first to check for sanctions, scam flags, and any suspicious on-chain activity?”
DeFi protocol counterparty screening
“Before our smart contract releases funds to 0xAbCdEf1234567890AbCdEf1234567890AbCdEf12 on Base, do a thorough deep-tier risk check — I need OFAC clearance, blacklist status, and a full behaviour analysis on that wallet.”
Compliance check before crypto payroll
“We're running crypto payroll to a new employee's Base wallet at 0x1234567890abcdef1234567890abcdef12345678 — please do the deepest available Verdix risk assessment on it before we process the transfer.”

Endpoint

Choose the deep tier when you need the most comprehensive risk assessment available — particularly for high-value transfers, onboarding new counterparties, compliance-sensitive payouts, or when a quick/standard tier returned a 'caution' result and you need deeper investigation. The deep tier adds full on-chain behaviour analysis and activity pattern review on top of the OFAC and blacklist checks offered by lighter tiers, making it the right choice when the cost of a bad transfer far exceeds the $0.50 screening fee.
Side effects
- Invalid address format (not matching 0x[40 hex chars] pattern) returns a validation error
- Unsupported chain value (anything other than 'base') returns an error
- Network timeout or upstream data provider outage may return 5xx errors
- Address with insufficient on-chain history may yield a limited behaviour analysis
- Payment failure (insufficient USDC) blocks the request before analysis begins
