The Rise of Infrastructure: Crypto On-Ramp Solution 'Fun' Raises $72 Million in Series A Funding

On May 1, 2026, the crypto infrastructure sector gained strong momentum as Fun, an on-ramping and payments solution company, secured a $72 million Series A funding round. This round was co-led by Multicoin Capital and SignalFire. As institutional investors like BlackRock strengthen their presence in the digital asset market, Fun's achievement demonstrates the concentration of capital into the core infrastructure of the blockchain ecosystem.

This $72 million funding is considered a rare large-scale investment in the crypto infrastructure field recently. Fun plans to use the capital to increase the scalability of its core services, which optimize deposit, withdrawal, and settlement processes. Investors expect Fun's technology to play a decisive role in simplifying complex payment flows between traditional financial systems and decentralized protocols.

Fun provides a powerful engine that supports the deposit, withdrawal, and settlement flows of leading crypto apps such as Polymarket, Lighter, and Aave.

Fun has established a unique position by managing the payment infrastructure for major market-leading decentralized applications (dApps). In particular, it is recognized as a core utility in the DeFi ecosystem by seamlessly supporting liquidity flows for the prediction market Polymarket and the lending protocol Aave. Use cases for major partners that have adopted Fun's infrastructure are as follows.

Multicoin Capital's Investment Philosophy and Market Reshaping

Multicoin Capital's investment is based on their investment thesis of a 'one-time shift in wealth.' They are convinced that blockchain networks will become a new alternative at a time when trust in traditional centralized financial institutions is declining. The large-scale investment in Fun is interpreted as a strategic move to secure a reliable payment layer amidst these macro changes.

• Gradual weakening of consumer trust in traditional financial intermediaries
• Opportunities in the process of trillions of dollars in assets moving to blockchain networks
• Enhancing decentralization and efficiency of financial services through technical innovation

In terms of the competitive landscape, the proliferation of embedded on-ramp solutions is notable. A prime example is fintech giant Stripe's integration with the Avalanche network to offer cryptocurrency purchase features. Fun differentiates itself from these general-purpose solutions by providing highly optimized payment flows and sophisticated infrastructure specialized for specific protocols, thereby securing a competitive advantage.

Institutional market participation is also a key factor supporting the demand for Fun's infrastructure. BlackRock's digital asset franchise generated $42 million in fee revenue in the first quarter of 2026 alone, establishing itself as a substantial revenue source on Wall Street. This influx of institutional capital and the changing metrics of major institutions can be clearly seen in the chart below.

Global Regulatory Environment and Regional Variables

Despite the positive investment climate, regulatory uncertainty remains. On May 1, 2026, the Central Bank of Brazil announced new foreign exchange regulations prohibiting the use of cryptocurrencies in regulated cross-border payment systems. This move aims to fully integrate cross-border payment flows into the regulatory framework and will serve as a significant regulatory milestone for on-ramp companies seeking global expansion.

Meanwhile, in the Asian market, Japan's SBI Holdings is accelerating its expansion into the digital asset ecosystem by pursuing an acquisition of a stake in Bitbank. SBI is making aggressive moves, including entering Singapore and launching card services through a partnership with Visa. These conflicting trends of regional regulation and market expansion create a complex landscape for infrastructure companies like Fun to navigate.

In conclusion, Fun's $72 million Series A funding signifies that crypto on-ramp technology has evolved beyond simple tools into institutional-grade financial infrastructure. While BlackRock's ETF performance and SBI's expansion demonstrate the market's immense potential, the regulatory case in Brazil serves as a reminder of the need for thorough compliance. Starting with this investment, technological competition and market consolidation in the infrastructure market are expected to accelerate further.
