Listen to this article

Coinbax completed a $4.2 million seed funding round, marking its initial major capital raise to support growth in stablecoin infrastructure. The round was led by BankTech Ventures, with additional investments from Connecticut Innovations, Paxos, and SpringTime Ventures, reflecting strong backing from fintech and blockchain specialists.

Coinbax, headquartered in New York City, operates as a programmable trust layer for stablecoin and tokenized deposit payments. Founded by Peter Glyman, who brings extensive fintech experience from co-founding Geezeo (a personal financial management platform acquired by Fiserv in 2019), the company focuses on bridging traditional finance with blockchain technology. Its core offerings include smart contracts for escrow, multi party approvals, spend limits, conditional releases, and real time compliance features like sanctions screening and KYC verification. Built on blockchains such as Base and Solana, Coinbax supports major stablecoins including USDC, USDG, RLUSD, and PYUSD, with plans for expansion to additional networks and compliant assets under frameworks like the GENIUS Act. The platform enables 24/7 instant settlements, cross border transfers, and integrations with enterprise systems, targeting use cases in treasury operations, trade finance, loan disbursements, and supplier payments.

The seed round, closed on December 22, 2025, raised $4.2 million without a disclosed pre  or post money valuation. BankTech Ventures served as the lead investor, emphasizing their interest in technologies that enhance risk controls for financial institutions. Participating investors include Connecticut Innovations (a state backed VC focused on tech and innovation in Connecticut), Paxos (a regulated stablecoin issuer), and SpringTime Ventures (an early stage fintech investor). This marks Coinbax’s first documented funding event, positioning it as an emerging player in the stablecoin ecosystem.

Coinbax’s $4.2 million seed funding round, announced on December 22, 2025, represents a significant milestone for the New York City-based fintech startup, which is positioning itself as a key enabler in the evolving landscape of stablecoin payments. Founded by Peter Glyman, a seasoned entrepreneur with a track record in financial technology, Coinbax aims to address critical gaps in institutional adoption of digital assets by providing a programmable trust layer that incorporates risk controls, compliance features, and seamless integrations. Glyman’s background includes co-founding Geezeo in 2006, a pioneer in personal financial management (PFM) software for banks and credit unions, which was acquired by Fiserv in 2019 after scaling to serve over 500 financial institutions. This experience in building compliant, scalable fintech solutions directly informs Coinbax’s approach to blending traditional banking workflows with blockchain innovation.

At its core, Coinbax offers a dual on-chain and off-chain architecture designed to make stablecoin transactions safe and practical for banks, fintechs, and enterprises. Key features include programmable escrow mechanisms that release funds based on conditions like delivery confirmations or time based triggers; built-in reversibility to mitigate fraud or errors through review windows and automated rollbacks; real time compliance tools for sanctions screening, KYC, and risk assessments; and instant 24/7 settlements that outperform legacy systems in speed and cost. The platform supports prominent stablecoins such as USDC (issued by Circle), USDG (from Paxos), RLUSD (Ripple’s stablecoin), and PYUSD (PayPal’s USD), initially built on the Base (an Ethereum Layer 2) and Solana blockchains, with expansions planned to accommodate more networks and assets compliant with emerging regulations like the GENIUS Act. This setup facilitates a range of applications, from treasury and supplier payments to escrow in contract settlements, trade finance, loan disbursements, milestone based payouts in industries like construction and manufacturing, and automated approvals for commercial transactions. By integrating with existing AP/AR (accounts payable/receivable) and ERP (enterprise resource planning) systems, Coinbax ensures auditability and regulatory alignment, making it appealing to risk averse institutions.

The funding round was led by BankTech Ventures, a venture firm dedicated to advancing community banking through technology investments. BankTech emphasizes an ecosystem model where bankers and tech founders collaborate to prioritize innovations that align with community banks’ needs, such as digital transformation and risk management tools. Carey Ransom, Managing Director at BankTech Ventures, noted in the announcement that Coinbax tackles a core obstacle to stablecoin adoption: risk. He emphasized the importance of clear rules, accountability, and oversight in banking workflows, stating, “What matters for banks is not speed alone, but having clear rules, accountability, and oversight. Coinbax gives financial institutions a practical way to use stablecoins inside real banking workflows.” Other participants include Connecticut Innovations, Connecticut’s state venture capital entity, which invests in high growth sectors like IT, biotech, and fintech to foster economic development, with recent commitments totaling $45.8 million in fiscal year 2025 across early stage companies; Paxos, a regulated blockchain infrastructure provider known for issuing stablecoins like USDG and Pax Gold, with a focus on 1:1 backed digital assets under oversight from bodies like the New York Department of Financial Services; and SpringTime Ventures, an early stage investor in fintech and digital assets. These backers bring a mix of regulatory expertise, stablecoin issuance experience, and banking focused innovation, signaling strong validation for Coinbax’s model.

The $4.2 million will be used to accelerate engineering development, enhance integrations with custody providers and wallet infrastructure, and facilitate the onboarding of design partners in commercial banking and enterprise payments. Peter Glyman, Coinbax’s Founder and CEO, articulated the vision: “Within the next three years, every bank account will have a wallet. Stablecoins and tokenized deposits will become part of every bank’s core infrastructure. To get there, institutions need tools that feel familiar: clear rules, approvals, and workflows they can trust. Controls make that possible.” This strategic allocation aims to position Coinbax at the forefront of the shift toward programmable money, particularly as traditional payment rails like RTP and FedNow lack the advanced controls that stablecoins can offer through smart contracts.

This funding occurs against a backdrop of rapid growth in the stablecoin sector. As of late 2025, the global stablecoin market capitalization has surpassed $280 billion, up from approximately $200 billion at the year’s start, with transaction volumes approaching $1 trillion monthly in some periods. Projections vary, but analysts anticipate the market could reach $500-750 billion in the coming years, driven by increasing institutional participation and regulatory frameworks that enhance trust and scalability. Institutional adoption has surged, with 13% of financial institutions and corporates already using stablecoins for payments, and over half of non users planning to adopt within the next 6-12 months, motivated by cost savings, speed, and cross border efficiency. Regulatory developments, such as the U.S. GENIUS Act requiring 1:1 reserve backing, have further bolstered confidence, shifting the sector into an “Age of Compliance” where stablecoins are increasingly viewed as infrastructure for modern finance rather than speculative assets.

However, challenges persist. The stablecoin space is competitive, with established players like Circle and Tether dominating market share, and new entrants focusing on compliance and interoperability. Coinbax’s emphasis on reversibility and policy enforcement could differentiate it, but widespread adoption depends on navigating regulatory hurdles and proving scalability in real world banking environments. Broader implications for financial stability include potential shifts in bank deposits and credit structures as stablecoins displace traditional funding sources, though experts suggest this could enhance liquidity and efficiency if managed properly. In 2025, stablecoins accounted for 30% of crypto transaction volume, underscoring their role in global commerce, with forecasts predicting up to $9 trillion in annual volume by institutions alone.

Overall, Coinbax’s funding underscores the maturation of stablecoins from niche crypto tools to foundational elements of global finance, with the company’s controls potentially accelerating this transition by making digital assets “feel familiar” to traditional institutions. As adoption grows, monitoring regulatory evolutions and competitive dynamics will be crucial to assessing Coinbax’s long term impact.
