As fintech companies expand their use of blockchain, privacy is becoming the fault line that separates innovation from exposure. The transparency that once made crypto appealing now threatens to reveal personal financial data, forcing startups to design around the open ledgers they once celebrated.
Seismic’s latest funding round shows how quickly that shift is accelerating. The startup raised $10 million led by a16z crypto, joined by Polychain, Amber Group, TrueBridge, dao5, and LayerZero, bringing its total capital to $17 million. CEO Lyron Co Ting Keh said Seismic’s mission is to build private blockchain rails that protect users’ financial details without losing the efficiency of crypto payments.

Funding scale
The new capital gives Seismic an edge in a race defined by privacy layers and secure interoperability. It follows a16z’s “State of Crypto” report, which found growing public concern over blockchain data visibility. Google searches for crypto privacy surged through 2025, showing that both consumers and institutions are seeking solutions that blend transparency with discretion.
Founder perspective
Co Ting Keh described Seismic as “boots on the ground,” emphasizing a customer-first approach to technical innovation. The startup partners with fintechs like Brookwell, which uses Seismic’s private rails for stablecoin accounts that operate outside traditional banks. Cred, a private credit platform, also uses its system to prevent transaction exposure. Co Ting Keh’s approach contrasts with larger, infrastructure-heavy players by focusing on intimacy and adaptability rather than scale alone.
Competitive field
Seismic enters a market defined by giants like Tempo, a Stripe-backed blockchain startup valued at $5 billion after a $500 million raise. Co Ting Keh acknowledged Tempo as “a powerhouse,” but argued that both can thrive if the demand for financial privacy continues to expand. Seismic’s pitch to fintech clients goes beyond functionality, offering broader operational support that aligns with their growth goals.
Market context
The timing of Seismic’s round suggests investor alignment around a single theme of controlled transparency. As crypto infrastructure merges with banking and payments, startups providing encryption and privacy layers are emerging as critical enablers. Fintechs experimenting with stablecoins, cross-border transfers, and credit platforms are now looking for systems that shield customer data while satisfying compliance requirements.
Near-term signal
Seismic’s roadmap now includes expanding partnerships and deploying its private rails with new financial institutions. Early adoption will likely determine whether smaller players can compete against Stripe-linked ecosystems or if consolidation will define the next cycle of blockchain finance.
Privacy as a differentiator has shifted from a technical feature to a commercial advantage. If fintech adoption of crypto continues at this pace, companies that can guarantee discretion may become the real gatekeepers of trust in digital finance. The coming year will show whether investors keep backing privacy infrastructure as enthusiastically as they fund transaction speed.
