How this service works
MCP tool: verify blockchain wallet address. Checks on-chain activity and risk flags.
Output
Returns a JSON object with wallet_valid (boolean indicating if address is a valid wallet), activity_score (0-100 integer measuring on-chain activity level), and risk_flags (array of identified risk indicators such as sanctions associations, mixer usage, or unusual patterns)
Example use cases
Vet supplier wallet before payment
“I'm about to send a large stablecoin transfer to a new supplier. Can you verify their wallet address 0x9876543210fedcba9876543210fedcba98765432 on Ethereum and let me know if there are any risk flags or if their activity score is decent?”
Screen customer deposits for fraud
“A customer just submitted this wallet address 0xabcdef1234567890abcdef1234567890abcdef12 for receiving their payout. Run a quick check on the on-chain activity and risk flags — I need to know if it looks legitimate before processing the withdrawal.”
Validate counterparty in swap deal
“Before I execute this token swap with a counterparty, verify their wallet 0x5555555555555555555555555555555555555555 on Polygon. Give me the activity score and any red flags so I know if they're a trustworthy actor.”
Technical details
Endpoint
POSThttps://limitguard.ai/v1/mcp/verify-wallet?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, automated risk check on a specific blockchain wallet address before executing a transaction or onboarding a counterparty. Prefer this over full entity compliance checks when you only have a wallet address (not a name/company), and need on-chain derived signals rather than off-chain KYC data. Ideal for agent-to-agent payment flows where wallet trust must be assessed programmatically.
Side effects
- Invalid wallet address format returns validation error
- Unsupported chain_id returns error indicating chain not supported
- Wallet with no on-chain history may return low activity_score with empty risk_flags
- Payment failure (402) if USDC balance insufficient
- Rate limiting if too many requests in short period
- Network timeout if on-chain data provider is slow
