M0 Secures $40 Million Series B as Stablecoin Infrastructure Gains Momentum

Stablecoin infrastructure startup M0 has successfully closed a Series B funding round worth $40 million, bringing its total capital raised to nearly $100 million. The round demonstrates intensifying venture capital interest in the stablecoin ecosystem, with major firms recognizing the sector’s critical infrastructure needs.

The funding was led by prominent crypto investors Polychain and Ribbit Capital, joined by the Endeavor Catalyst fund and existing backers Pantera and Bain Capital Crypto. The startup declined to disclose its post-money valuation. M0 remains focused on addressing a core challenge in the stablecoin space: enabling multiple issuers to deploy tokens efficiently across different blockchains without requiring each to build proprietary cross-chain bridging and token conversion infrastructure.

Building the Foundation Layer for Digital Money

M0’s core proposition centers on creating what co-founder and CEO Luca Prosperi describes as “the layer zero of money.” Rather than forcing each stablecoin issuer to solve the same technical problems independently, M0 provides a unified network where issuers can deploy and manage stablecoins with interoperability built in. This approach significantly reduces time-to-market and development costs for new stablecoin projects.

The infrastructure plays a crucial role in a market experiencing rapid expansion. Stablecoins—digital tokens pegged to traditional assets like fiat currencies—have become increasingly central to crypto market infrastructure, bridging the gap between traditional finance and decentralized digital assets.

Regulatory Clarity Fuels Market Growth

The investment surge reflects changing market conditions. Following the passage of the GENIUS Act by the U.S. House last month, regulatory clarity around stablecoin issuance and management has improved substantially. This legislative development removed significant uncertainty that had previously constrained stablecoin proliferation.

The results are quantifiable: the global stablecoin market capitalization surpassed $289 billion as of August 2025, more than doubling in size throughout the year. This explosive growth has attracted venture capital firms eager to capture value from infrastructure and enabling technologies positioned to support continued expansion.

Capital Flowing Into Critical Infrastructure

M0’s funding round represents one of the largest recent investments in stablecoin-related projects, reflecting broader venture trends. Multiple funding rounds have closed across the sector as institutional investors increasingly recognize that stablecoin infrastructure companies occupy a critical position in the emerging digital finance ecosystem.

The concentration of capital among top-tier venture firms—including Polychain’s track record in blockchain infrastructure and Ribbit Capital’s fintech expertise—signals institutional confidence in both M0’s technology and the longer-term stablecoin market opportunity.
