As decentralized finance matures, real-world assets (RWAs) are emerging as the critical bridge between traditional finance and blockchain’s programmable, global infrastructure. What started as an experiment is now becoming a core primitive of on-chain capital markets.
Tokenized U.S. Treasuries, real estate, and private credit are already attracting institutional capital. By mid-2025, BlackRock’s BUIDL fund had tokenized nearly $3B in Treasuries, delivering on-chain yields of 5–6%. Platforms like Ondo Finance and Franklin Templeton manage billions in tokenized assets, while private credit RWAs offer 8–12% APY, outperforming many traditional instruments. Industry estimates from BCG and ADDX project the tokenized asset market could reach $16 trillion by 2030.
However, this growth is happening in a multi-chain world, and that introduces serious challenges.
The Fragmentation Problem
RWAs issued on one chain often can’t move seamlessly to another. Liquidity becomes siloed, compliance checks are duplicated, and settlement flows are slow and expensive. Moving RWAs across chains frequently requires re-tokenization and repeated KYC, resulting in 2–5% fees and multi-day delays.
To scale RWAs globally, cross-chain systems must deliver:
- Universal liquidity across chains
- Portable compliance without repeated KYC
- Secure settlement with strong finality
- Reusable identity via decentralized credentials
Interoperability isn’t optional — it’s foundational.
Legal, Data and On-Chain Foundations
RWAs rely on hybrid legal structures that connect on-chain tokens to enforceable off-chain rights. Most issuers use SPVs or trusts to hold assets, while tokens represent contractual claims rather than direct ownership. Custodians safeguard assets, and registrars maintain authoritative records that sync with blockchains via oracles.
Data integrity is equally critical. Oracles like Chainlink deliver NAV updates, proof-of-reserves, and corporate actions using aggregation and cryptographic proofs. These inputs create immutable, auditable trails that regulators and institutions can trust.
On-chain representations vary by asset type:
- ERC-20 for fully backed or wrapped RWAs
- ERC-4626 vaults for yield-bearing assets
- NFT-based models for unique or fractionalized assets
Identity, Compliance and Cross-Chain Messaging
Modern RWA stacks use Decentralized Identifiers (DIDs) and Verifiable Credentials (VCs) to enforce KYC, accreditation, and jurisdiction rules. Standards like ERC-3643 embed compliance directly into token transfers, ensuring only verified wallets can interact.
For cross-chain movement, messaging layers such as Chainlink CCIP, LayerZero, IBC and Axelar synchronize state across networks. New omnichain models avoid fragile wrapped tokens, making them better suited for high-value RWAs.

The Big Picture
RWAs are reshaping on-chain finance — but only if they’re interoperable, compliant, and secure by design. Cross-chain architecture transforms fragmented ecosystems into unified, global markets where assets move as easily as native crypto.

This is a solid breakdown of where RWAs actually get hard: interoperability, compliance, and settlement, not tokenization itself. Cross-chain + portable compliance feels like the real unlock if RWAs are going to scale beyond isolated pilots. Curious which messaging layer you think is most production-ready for high-value RWAs right now
