Every transformative technology era is built on an infrastructure stack — a layered set of technologies, protocols, and services that enable the applications and platforms that end users actually interact with. The internet era was built on TCP/IP at the base, HTTP and DNS in the middle, and cloud computing and content delivery networks at the application layer. The tokenization era is being built on an analogous stack — and understanding that stack is essential for anyone seeking to build, invest, or operate in the tokenization economy.
Layer 1: The Blockchain Settlement Layer
At the base of the tokenization stack are the blockchain networks that provide the settlement and custody infrastructure for tokenized assets. Ethereum remains the dominant platform for institutional tokenization, but a growing number of purpose-built institutional blockchain networks — including several developed specifically for regulated financial assets — are competing for this foundational role. The choice of settlement layer has implications for throughput, finality, regulatory acceptance, and interoperability with the traditional financial system.
The institutional settlement layer is not yet standardised, which creates both risk and opportunity. The networks that establish themselves as the preferred infrastructure for regulated asset tokenization will capture a dominant position in the tokenization economy for years to come.
"The tokenization stack is being built right now, by hundreds of companies, in dozens of countries, across every layer simultaneously. The winners of the infrastructure race will define the economics of the tokenization era."
Layer 2: Compliance and Identity
Above the settlement layer sits the compliance and identity infrastructure — the systems that ensure tokenized assets can only be held and traded by parties who have satisfied applicable know-your-customer, anti-money-laundering, and investor qualification requirements. This layer is critical for institutional adoption, because no regulated financial institution can participate in tokenized asset markets without confidence that the compliance infrastructure is robust.
Several specialist providers have built sophisticated on-chain compliance systems, including investor whitelists, transfer restrictions, and automated regulatory reporting. This layer is less visible than the blockchain itself but arguably more important for institutional market development.
Layer 3: Oracles and Real-World Data
Tokenized real-world assets require accurate, reliable connections between blockchain-native tokens and the real-world assets they represent. Oracles — services that bring verified real-world data on-chain — are the bridge between tokenized assets and reality. Property valuations, commodity prices, income streams, and audit certifications all need to be reliably reported on-chain for tokenized assets to function as reliable financial instruments.
The oracle problem — ensuring data accuracy and preventing manipulation — is one of the most important unsolved challenges in RWA tokenization. The providers that solve it reliably will occupy a critical position in the tokenization stack for the entire era.
