"Real-world assets onchain" — or RWA, as the crypto industry calls it — has become one of the most discussed categories in DeFi. BlackRock is doing it. Franklin Templeton is doing it. Dozens of startups are building the infrastructure to make it work at scale.

But most of the coverage focuses on the product layer — the tokenized fund, the stablecoin, the yield instrument — without explaining the full stack that makes it possible. This article is for GPs, fund managers, and investors who want to understand what's actually being built, layer by layer.

What RWA Means and Why It Matters

Real-world assets are financial instruments that exist outside the blockchain — equities, bonds, real estate, private credit, commodities, fund interests. RWA tokenization is the process of representing these instruments as blockchain tokens, enabling them to be held, traded, and used as collateral in DeFi protocols.

The appeal is straightforward: the global stock of real-world financial assets is roughly $500 trillion. The total value locked in DeFi is a few hundred billion. Bringing even a fraction of traditional finance onchain would dwarf the current DeFi ecosystem — and would make onchain infrastructure the default settlement layer for global capital markets.

That's the long-term thesis. The near-term reality is that RWA tokenization is moving fast in specific categories — US Treasuries, private credit, and increasingly pre-IPO equity — where the tokenization premium (yield + liquidity) is large enough to justify the infrastructure investment.

The Full Infrastructure Stack

Understanding RWA tokenization requires understanding five distinct layers, each of which has its own technical and regulatory requirements.

Layer 1: The underlying asset and legal custody

The foundation of any RWA product is the underlying asset and who legally holds it. This can be a custodian bank, a licensed trust company, a special purpose vehicle, or a regulated entity with authority to hold the asset class in question. The legal claim on the underlying asset is what gives the token its value — without a credible legal framework, a "tokenized" asset is just a token with a story.

For private equity, this typically means an SPV or fund structure holds the underlying shares, with fund administration handling the legal record. For US Treasuries, it means a regulated custodian holds the bonds and issues receipts.

Layer 2: Fund administration and compliance

Before anything gets tokenized, the underlying legal and compliance infrastructure has to be in place. KYC/AML checks on investors, accreditation verification, subscription agreements, cap table management — this is the layer that Allocations operates in. It's unglamorous but essential. An RWA token without credible underlying administration is a security with no defensible chain of custody.

This layer also handles tax reporting (K-1s, 1099s), regulatory filings (Form D, blue sky filings), and investor communications. When an on-chain transfer of a tokenized LP interest happens, the fund admin needs to reflect that transfer in the official legal record.

Layer 3: The tokenization layer

Once the legal infrastructure is in place, the tokenization layer represents the underlying asset as a blockchain token. The key decisions here are: which blockchain (Ethereum, BNB Smart Chain, Base, Solana), which token standard (ERC-20, ERC-1400, ERC-3643), and how transfer restrictions are enforced (on-chain, off-chain, or hybrid).

ERC-1400 and ERC-3643 are the most common standards for tokenized securities because they include built-in transfer controls — you can encode accredited investor requirements, lock-up periods, and geographic restrictions directly into the token contract. This makes compliance programmable rather than manual.

Layer 4: The DeFi integration layer

This is where RWA tokenization intersects with DeFi — where tokenized assets become composable with lending protocols, AMMs, stablecoin mechanisms, and yield aggregators. The token from Layer 3 becomes a primitive that other protocols can build on.

OpenStocks is a clear example of Layer 4 infrastructure. The protocol takes tokenized pre-IPO equity (the Layer 3 asset) and uses it as collateral to issue USDOS — a DeFi-native stablecoin on BNB Smart Chain. Staking USDOS generates up to 15% APY, with yield derived from the underlying equity portfolio of SpaceX, OpenAI, and Anthropic. This is DeFi composability applied to a private market asset — something that wasn't technically possible even five years ago.

Layer 5: Secondary markets and liquidity infrastructure

The final layer is where tokenized RWAs are traded, priced, and used as collateral in broader DeFi ecosystems. This includes compliant secondary markets for tokenized securities, DEX liquidity pools for RWA-backed stablecoins, and lending markets that accept RWA tokens as collateral.

This layer is the least mature. Secondary liquidity for tokenized private equity is thin. Lending markets for RWA tokens are nascent. But the infrastructure is being built — and the trajectory is clear.

Where the Bottlenecks Are

The RWA stack has progressed unevenly across its five layers. Layers 3 and 4 (tokenization and DeFi integration) have moved fastest because they're primarily software problems. Layers 1, 2, and 5 (legal custody, fund administration, and secondary markets) have moved slower because they involve regulatory frameworks, institutional relationships, and market-making operations that take longer to build.

The result is that there's more tokenization infrastructure than there is high-quality underlying asset infrastructure to support it. Any protocol that gets Layer 1 and Layer 2 right — credible legal custody, compliant fund administration, transparent reporting — creates a durable competitive advantage because it's the hardest part to replicate.

This is why fund administrators like Allocations matter in the RWA ecosystem. The product layer (the stablecoin, the tokenized fund) is what investors see. The administration layer is what makes it trustworthy.

The Convergence Thesis

The most interesting thing about RWA infrastructure is where it's converging: traditional finance and DeFi are building toward each other from opposite directions.

Traditional finance is tokenizing existing products — money market funds, bond ETFs, private credit facilities — and putting them onchain. DeFi is building new products — stablecoins, yield instruments, structured products — backed by traditional assets. The middle ground, where a fully onchain product has fully compliant traditional asset backing, is where the most interesting infrastructure is being built.

OpenStocks sits squarely in this convergence: a DeFi protocol (Layer 4) built on properly administered private equity (Layers 1–2), using compliant tokenization (Layer 3), with DeFi-native liquidity (Layer 5 in early form). Allocations provides the Layer 2 foundation that makes the rest of the stack credible.

What to Watch Over the Next 12 Months

The RWA category will see significant developments in the near term. Regulatory clarity in the US on tokenized securities will either accelerate or constrain secondary market development — the SEC's position on whether token transfers require broker-dealer involvement is still being tested. Institutional adoption will continue: more asset managers will launch tokenized products, which will drive demand for compliant administration infrastructure. And on-chain liquidity for private assets will deepen as more protocols build on top of tokenized RWA primitives.

For GPs and fund managers, the implication is the same as it's been throughout this article: the decisions you make about structure, administration, and tokenization optionality today determine how much flexibility you have as this infrastructure matures. Build on solid legal and administrative foundations. Choose platforms that understand both worlds.
