Paxos, the blockchain infrastructure firm behind the USDP stablecoin, has laid out a six-layer framework for stablecoin payment systems. The model tackles the licensing, custody, and regulatory challenges that have kept stablecoins from fully integrating into mainstream payments.
Why the framework matters
Stablecoins have grown rapidly in trading and DeFi, but real-world payments remain a bottleneck. Paxos argues that the missing piece isn't technology — it's the institutional infrastructure around custody, licensing, and compliance. The six-layer approach breaks down what a payments-grade stablecoin system needs to function at scale.
What the six layers cover
The company didn't name every layer publicly in detail, but said the framework addresses three core hurdles: licensing, custody, and regulatory compliance. The other three layers likely involve settlement, token management, and network interoperability, though Paxos hasn't specified them in this release. What's clear is that each layer is meant to solve a distinct problem that prevents stablecoins from being used like traditional payment rails.
Licensing, for example, ensures the issuer holds the proper charters to operate across jurisdictions. Custody deals with how private keys are stored and who controls them — a point of friction for institutional adopters. Regulatory compliance covers anti-money laundering checks, sanctions screening, and transaction monitoring.
Where the industry stands
Right now most stablecoin projects handle these functions in silos. Some rely on third-party custodians, others on self-custody. Few have integrated licensing from day one. Paxos's framework suggests that a mature stablecoin payment network would need all six layers working together, not as add-ons.
The company has itself navigated regulatory scrutiny. It settled with the SEC in 2023 over the BUSD stablecoin and has since focused on regulated products. That experience likely informs the six-layer model.
What comes next
Paxos hasn't announced any specific product built on this framework. The company said it plans to work with regulators and payment partners to push the model forward. Whether other stablecoin issuers adopt the same blueprint — or whether regulators require it — remains an open question.
