FinowlFinowl for Crypto exchanges
Stop account takeover on crypto exchanges and wallets
On a crypto exchange, an account takeover is rarely recoverable. Once an attacker logs in with reused credentials, changes the withdrawal address and moves funds on chain, there is often no chargeback and no bank to call. That makes exchanges, custodial wallets and trading apps some of the most persistent targets for credential stuffing, especially during price rallies when new users rush to sign up.
Finowl lets crypto platforms check emails and passwords against Finowl Intelligence at the points that matter most: account creation, login, API key generation and withdrawal address changes. Results are fast JSON responses you can feed into existing risk engines. Gender prediction is available too, but for exchanges it is limited to aggregate audience analytics and must never influence trading limits, verification or access.
WHAT TEAMS RUN INTO
Challenges in crypto exchanges
Irreversible withdrawals
On-chain transfers cannot be reversed. Stopping a takeover before a withdrawal address is changed is far cheaper than investigating after funds leave the platform.
Credential stuffing at scale
Attackers replay billions of leaked credentials against exchange logins, often from rotating proxies, hoping that a small share of users reused passwords from older breaches.
Market-driven signup spikes
Price rallies bring sudden waves of signups. Security checks must keep up with traffic bursts without slowing onboarding at the moment new users are most eager to trade.
API key abuse
Trading API keys created from a compromised account can be used to drain balances through manipulated trades, so key creation deserves the same scrutiny as withdrawals.
HOW FINOWL HELPS
Three APIs, one integration
Email breach checks for crypto exchanges
An exchange account tied to an email that appears in breach data is more likely to face credential stuffing, phishing and SIM-swap follow-up attacks. Finowl checks the address against Finowl Intelligence and returns each breach with its date, data classes and verification status. A breach that exposed passwords, or a stealer log entry flagged by IsStealerLog, is a strong signal that the account deserves stricter controls.
Breached password checks for crypto wallets and exchanges
Credential stuffing works because people reuse passwords, and the payoff from a crypto account makes exchanges a favorite target. Blocking passwords that already appear in breach data removes the credentials attackers try first. Finowl returns whether a password has been seen and how often, so you can reject widely circulated values outright and nudge users away from rarer ones, in line with NIST SP 800-63B guidance.
Aggregate audience analytics for crypto platforms
Crypto marketing teams often want to know whether education content, referral programs and community events reach beyond a narrow audience. Finowl gender predictions estimate how names or email local parts are typically used, which can produce an aggregate view of who signs up for a newsletter or attends an online explainer session. Those numbers help plan more inclusive outreach and content.
