At Nansen, we're building a trading platform that demands high-quality, cross-chain live price data — so when we went looking for the best onchain data available, we did a thorough search of the market. Bitquery came out on top. What's kept us there is the team. They're genuinely locked in — they respond instantly, and rather than handing us an off-the-shelf product, they tailored an offering specifically to our needs. We recently flagged elevated P95 latency on one of our TradingView OHLCV queries, and their team had us sorted within minutes. We don't think of Bitquery as a vendor. They're a partner. Bitquery now powers all live prices across Nansen.

A Bug Could Have Printed Unlimited Zcash For Four Years. Did Anyone?
A flaw in Zcash's Orchard circuit could have minted counterfeit ZEC invisibly since May 2022. The forgery itself is private by design, but cashing out is not. We pulled the full chain history and checked the turnstiles to find out whether anyone actually exploited it.

Why Stellar custodians, anchors, and payment products use Bitquery as the upstream for their deposit-detection pipelines. The Stellar transfer schema, what each record carries, the API patterns the data supports, and how delivery works at enterprise scale through cloud data dumps to S3, Snowflake, or Google Cloud.
