Coinbax has raised $4.2 million in seed funding as it looks to accelerate the development of its programmable trust and control layer for stablecoin-based payments. The funding round was led by BankTech Ventures, with participation from Connecticut Innovations, Paxos, SpringTime Ventures, and several strategic investors from the banking and payments infrastructure space, according to data from RootData.
The raise comes at a time when stablecoins are increasingly being explored by banks and fintechs for real-time settlement, treasury management, and cross-border payments. While blockchain rails offer speed and efficiency, many institutions remain cautious due to compliance, governance, and operational risk concerns. Coinbax is positioning itself to address that gap.

Founded with a focus on institutional adoption, Coinbax is building what it describes as a “programmable trust layer” for stablecoin payments. Rather than acting as a wallet or issuing a stablecoin itself, the platform sits on top of existing stablecoin infrastructure and adds policy-driven controls. These include escrow logic, conditional payments, multi-party approvals, spending limits, and programmable release rules that can be enforced on-chain.
The company argues that while instant payment systems such as RTP and FedNow have improved settlement speed in traditional finance, stablecoins require additional guardrails to be safely deployed at scale by regulated entities. Coinbax’s software is designed to integrate stablecoins into existing compliance, risk management, and approval workflows familiar to banks and enterprises.
According to Coinbax, the newly raised capital will be used primarily to expand its engineering team, deepen integrations with custody and wallet providers, and onboard early design partners across commercial banking and enterprise payments. The company is currently building across multiple blockchain ecosystems, including Base and Solana, with support for major dollar-backed stablecoins such as USDC, PYUSD, RLUSD, and USDG. Additional chains and assets are expected to be added over time.
Founder and CEO Peter Glyman has previously said that the long-term direction of financial infrastructure points toward a convergence between traditional bank accounts and blockchain-based wallets. In that environment, he believes institutions will demand stablecoin systems that feel as controlled and auditable as legacy financial products, without sacrificing the efficiency of on-chain settlement.
Investors backing the round appear aligned with that view. BankTech Ventures, which focuses on technologies relevant to banks and financial institutions, has highlighted the need for risk-aware stablecoin infrastructure as adoption expands beyond crypto-native use cases.
Coinbax’s raise adds to a growing wave of infrastructure-focused startups targeting the “plumbing layer” of digital asset payments. Rather than competing on consumer-facing products, these companies are increasingly focused on enabling banks, fintechs, and enterprises to use stablecoins within existing regulatory and operational frameworks.
As stablecoins move closer to the core of global payment systems, platforms like Coinbax are betting that programmable controls and governance will be essential for bridging the gap between blockchain rails and institutional finance.
