Alterya

Alterya is an AI-powered fraud-prevention company founded in 2022 (Y Combinator; seed round led by Battery Ventures, ~$9.8M) that detects authorized-fraud scams — authorized push-payment (APP) scams, pig-butchering and romance scams, money-mule and synthetic accounts, and social-engineering-driven withdrawals — before victims send funds. It connects fraud signals across crypto rails and traditional fiat/bank rails, and prior to acquisition monitored more than $8B in transactions per month for exchanges and fintechs including Binance, Coinbase, and Block, protecting roughly 100M end users. Chainalysis acquired Alterya in January 2025 for a reported ~$150M; it now ships as the "Alterya by Chainalysis" fraud-prevention product. The standalone alterya.com domain is parked and the company operates entirely inside Chainalysis, with no independent public developer portal, API, or OpenAPI surface.

Alterya is profiled on the APIs.io network. Tagged areas include Company, Fraud Prevention, Fraud Detection, Cryptocurrency, and Blockchain.
