Screen any wallet for sanctions & risk. Verdict, labels & exposure in one query.
Skip stitching OFAC spreadsheets, label feeds and manual transaction reviews. Bitquery screens any address against sanctions lists, scores its 0–100 risk, attaches entity labels and quantifies its exposure to mixers, hacks and sanctioned entities — one GraphQL query, or a live KYT stream into your compliance workflow.
Every wallet, screened and scored.
Bitquery doesn't just flag a hash — it returns a verdict. Each address comes with a 0–100 risk score, the entity labels behind it and the exposure path that earned the flag, so a compliance officer can clear, review or block in a single glance.
See the exposure, hop by hop.
A flagged wallet isn't a mystery — it's a path. One query expands an address into the hops that drove its score: a mixer deposit, an indirect route to a sanctioned entity, and the clean KYC venue at the end. Exactly what an audit trail needs.
Screening a wallet shouldn't mean a spreadsheet and a guess.
Doing screening yourself means scraping OFAC lists, buying and stitching label feeds, replaying transfers to trace exposure and reviewing transactions by hand — and a single missed hop is a compliance breach. We indexed and labeled wallets across every chain, so a verdict is one query.
The compliance workflows teams ship on us.
Each one is a filter on the same indexed label, risk and transfer data — call GraphQL on demand for onboarding, or subscribe over webhook for continuous KYT.
KYT transaction screening
Score every incoming and outgoing transaction in real time, holding or flagging transfers tied to sanctions, mixers or hacks before they settle.
Explore Money Flow →Sanctions monitoring
Maintain a watchlist of sanctioned and high-risk wallets and get an alert the instant one of them moves funds — continuous, not a one-off check.
Read the docs →Onboarding risk checks
Run a one-call sanctions check, risk score and entity-label lookup at sign-up to gate or escalate a new wallet before you ever take its deposit.

"We did a thorough search of the market for the best onchain data. Bitquery came out on top — and now powers all live prices across Nansen. We don't think of them as a vendor. They're a partner."
Bitquery does the hard work of parsing blockchain transaction data into a usable form so that we don't have to. We use their interface to diagnose issues with complex transactions and their analytics as a starting point for our own.
They proved they had the technology to deliver sophisticated data solutions. We extended our support through the Binance X fellowship — building an open-source library of visualization widgets on their blockchain data.
The complex raw data is available at different levels of detail and from different viewpoints — whether we need simple aggregated transfers or parameters for failed contract calls. The support is responsive, friendly and quick.
Partnering with Bitquery has been highly cost-effective — leveraging their established infrastructure rather than building our own let us rapidly expand our blockchain support and reach a much broader segment of on-chain users.
Bitquery's products are very intuitive and easy to use. We currently use their products to obtain DEX-related trading and liquidity information, which saves us the manpower and tedious technical details required to develop our own system. Their excellent technical team deserves special praise; they provide near-24/7 support and resolve issues quickly. I greatly appreciate their products and work ethic.
Bitquery provides the infrastructure we rely on every day. Fast, reliable, and comprehensive across the chains that matter to our business.
