Check if a blockchain address is blacklisted by token issuers (e.g. Tether, Circle, Coinbase, Paxos) or sanctioned by the US Treasury’s Office of Foreign Assets Control (OFAC). See Understanding Risk Scores for how this fits into Range’s broader risk methodology.

Token Blacklist Events — Real-time monitoring on Ethereum, Tron, and Solana for specific stablecoin issuers.
OFAC Sanctions — Sourced from official OFAC reports and covers any network published by OFAC.

Sanctions & Blacklists Only: This endpoint checks if a wallet has been sanctioned (OFAC, EU, etc) or blacklisted by asset issuers (Circle, Tether etc). For a more comprehensive check for malicious actors, use the Address Risk Score endpoint.

How It Works

The endpoint performs two types of checks:

Token Blacklist Check — Monitors on-chain blacklist events emitted by stablecoin issuer contracts on Ethereum, Tron, and Solana. When issuers like Tether or Circle blacklist an address, it is blocked from transferring their tokens. The endpoint tracks both blacklist and unblacklist events in real-time to determine the current status.
OFAC Sanctions Check — Cross-references the address against the US Treasury OFAC Specially Designated Nationals (SDN) list. OFAC data is sourced from official published reports and covers any network published by OFAC.
Attribution Data — In addition to real-time blacklist events, the endpoint includes attribution labels that may provide extended context and information beyond what is captured in on-chain events.

Note: The is_token_blacklisted field reflects the current status based on the most recent event. An address that was blacklisted and later unblacklisted will show false. Use blacklist_event_history to view the complete history.

Path Parameters

Name	Type	Required	Description
address	string	✅	Blockchain address to check

Query Parameters

Name	Type	Required	Default	Description
network	string	❌	all	Filter blacklist events by network
include_details	boolean	❌	true	Include event history, token status breakdown, and attribution

Recommendation: In general, we do not recommend using the network parameter. Omitting it ensures comprehensive screening across all networks for both blacklist events and OFAC sanctions. Only use the network parameter if you have a specific use case, such as:

Limiting the search to a specific network for performance reasons

Checking an address format that exists on multiple networks (e.g., EVM addresses on Ethereum vs other EVM-compatible chains)

OFAC Sanctions Coverage

OFAC sanctions data is sourced from official US Treasury reports and is network-agnostic. If an address appears in OFAC publications, we flag it across all 300+ networks we support. See Supported Chains for full coverage.

Supported Networks & Tokens (Blacklist Events)

Real-time blacklist event monitoring is available for the following stablecoin issuers:

Network	USDT (Tether)	USDC (Circle)	CBBTC (Coinbase)	USDP (Paxos)
Ethereum	✅	✅	✅	✅
Tron	✅	✅	—	—
Solana	✅	✅	—	—

Clean Address

An address with no sanctions or blacklist history.

curl -G "https://api.range.org/v1/risk/sanctions/0x1234567890abcdef1234567890abcdef12345678" \
  -H "Authorization: Bearer your_api_key_here"

Minimal Response

Use include_details=false for high-volume screening when you only need pass/fail results.

curl -G "https://api.range.org/v1/risk/sanctions/0x1da5821544e25c636c1417ba96ade4cf6d2f9b5a" \
  --data-urlencode "include_details=false" \

Errors

HTTP Code	Cause	Recommended Action
400	Invalid address format	Validate the address format before making the request
429	Rate limit exceeded	Implement exponential backoff and retry
5xx	Internal server error	Retry after a short delay; contact support if persists

Best Practices

Check both flags — Always check both is_token_blacklisted and is_ofac_sanctioned for comprehensive compliance screening.
Real-time checks — Blacklist status can change; avoid caching for high-risk use cases.
Use full details — Keep include_details=true (default) when you need event history.
Addresses are case-insensitive — Both 0x1DA5... and 0x1da5... return identical results.

Use Cases

Pre-transaction screening — Check counterparty addresses before processing payments or transfers.
Exchange compliance — Screen addresses during deposit/withdrawal flows.
DeFi integration — Add sanctions checks to smart contract interactions or front-ends.
Audit trails — Generate compliance reports with full event history.
