Why Ethereum Dominates Real-World Asset Tokenization

Tokenized real-world assets crossed $38 billion in on-chain distributed value by late 2026, according to rwa.xyz trackers. Ethereum holds roughly 48% of that total: more than $22 billion spread across tokenized Treasuries, private credit, equities, and commodities. No other chain comes close in dollar terms. Understanding why requires looking beyond market cap and into the infrastructure that institutions actually depend on: token standards, audit tooling, custody integrations, and regulatory familiarity.

What RWA Tokenization Means for Institutions

Asset tokenization is the process of representing ownership of a traditional financial instrument as a digital token on a blockchain. When BlackRock issues a tokenized Treasury fund or Franklin Templeton puts money-market shares on-chain, they are creating blockchain-native records that settle in minutes rather than the T+1 or T+2 windows of traditional finance.

Institutions care about three things: legal clarity around the token's status as a security, infrastructure that integrates with existing custody and compliance workflows, and liquidity deep enough to handle large redemptions. Ethereum has built advantages in all three areas over nearly a decade of production use.

Ethereum's Market Share by the Numbers

Ethereum's dominance in RWA tokenization has been declining in percentage terms even as its absolute value grows. In early 2026, rwa.xyz data showed Ethereum at roughly 65% of tokenized RWA value. By September 2026, that share had fallen to about 48%, while the dollar amount on Ethereum rose from approximately $10 billion to over $22 billion. The decline in share reflects faster growth on competing chains rather than capital leaving Ethereum.

Data source note: RWA market figures vary significantly across trackers. rwa.xyz, Token Terminal, and DefiLlama each use different methodologies. The figures in this article primarily reference rwa.xyz distributed asset value, which excludes stablecoins.

Why Institutions Chose Ethereum

ERC-20 and ERC-3643: Standards That Fit Compliance

The ERC-20 standard gave Ethereum a universal interface for fungible tokens. Every wallet, exchange, and custodian already speaks ERC-20. But for regulated securities, plain ERC-20 tokens lack the access controls that issuers need: the ability to restrict transfers to whitelisted addresses, enforce holding periods, and comply with jurisdictional rules.

ERC-3643 fills that gap. Originally developed as the T-REX protocol by Tokeny Solutions, ERC-3643 adds an on-chain identity layer called ONCHAINID that checks every transfer against predefined eligibility rules. An issuer can enforce that only accredited investors in approved jurisdictions may hold the token, and the smart contract itself blocks non-compliant transfers at the protocol level.

The ERC-3643 Association counts 92 members as of 2026, and the standard maps to regulatory frameworks including MiFID II, SEC Reg D/Reg S, and AIFMD. For institutions that need to issue securities on a public chain while maintaining compliance, ERC-3643 is the most battle-tested option available.

Audit Tooling and Smart Contract Security

Ethereum's smart contract audit ecosystem is the deepest in the industry. Firms like Trail of Bits, OpenZeppelin, Consensys Diligence, and Certora have spent years building formal verification tools, static analyzers, and audit playbooks specifically for Solidity. When a fund manager needs to assure regulators and investors that a tokenized fund's smart contracts behave correctly, Ethereum offers the most mature toolchain for proving it.

This matters more than it might seem. Institutional adoption is gated by risk committees, not developers. A risk committee wants to see that the code was audited by a known firm using established methodology, that the language has a track record, and that bugs can be caught with automated tools. Ethereum's Solidity ecosystem satisfies those requirements in ways that newer chains cannot yet match.

Custody Infrastructure

Qualified custodians are a regulatory requirement for institutions managing client assets. Ethereum is supported by every major custodian: Coinbase Prime, BitGo, Fireblocks, Anchorage Digital, Copper, and BNY's Digital Assets division. These custodians have built deep integrations with Ethereum's transaction model, EIP-1559 fee mechanics, and staking infrastructure.

Adding support for a new chain is not trivial for a custodian. It requires new key management logic, transaction-signing flows, fee-estimation modules, and regulatory review. Ethereum's first-mover advantage here creates a self-reinforcing cycle: institutions go where custodians support them, and custodians prioritize chains where institutions deploy.

Regulatory Familiarity

Regulators in the United States, European Union, and Singapore have spent years studying Ethereum. The SEC's enforcement actions, the EU's MiCA framework, and Singapore's MAS tokenization pilots all reference Ethereum directly or implicitly. For an institution's legal team, deploying on a chain that regulators have already examined is meaningfully different from deploying on one they have not.

The Major Institutional Projects

BlackRock BUIDL

BlackRock's USD Institutional Digital Liquidity Fund, known as BUIDL, launched in March 2024 through Securitize as the tokenization and transfer agent. BUIDL invests in U.S. Treasury bills, repurchase agreements, and cash, distributing yield daily to token holders. By mid-2026, the fund held approximately $2.9 billion in total AUM across nine blockchains: Ethereum, Avalanche, Solana, Aptos, Arbitrum, Optimism, Polygon, and BNB Chain.

BUIDL originally launched exclusively on Ethereum. Its multi-chain expansion began in late 2025, but Ethereum remains the primary settlement layer. The fund's deployment on Ethereum gave it immediate compatibility with DeFi protocols: BUIDL tokens were integrated as collateral on decentralized exchanges and accepted as margin on centralized venues like Binance.

Franklin Templeton BENJI

Franklin Templeton's OnChain U.S. Government Money Fund (FOBXX) was the first U.S.-registered fund to use a public blockchain for transaction processing and share ownership recording. The fund, accessible through the BENJI token, held approximately $828 million in AUM as of Q1 2026.

Unlike BUIDL, BENJI launched primarily on Stellar, where it held over $650 million of its total value as of April 2026. It has since expanded to eight public blockchains including Ethereum, Base, Arbitrum, and Solana. Stellar's dominance in BENJI distribution illustrates an important point: Ethereum's RWA lead is not universal across every product category. For payment-oriented tokenized funds, Stellar's native asset issuance and low fees remain competitive.

Securitize as Infrastructure

Securitize functions as the tokenization layer for several of the largest institutional RWA projects. The platform reported over $3.1 billion in tokenized assets under management as of December 2025 and filed for a public listing in 2026 under the ticker SECZ. Its client list includes BlackRock, Apollo, Hamilton Lane, KKR, and VanEck.

Securitize's architecture is Ethereum-native. Its token standard, DS Protocol, builds on ERC-20 with added compliance modules for transfer restrictions, investor accreditation checks, and regulatory reporting. This deep Ethereum integration is a practical example of how the ecosystem's composability creates switching costs: migrating away from Ethereum means migrating away from Securitize's toolchain, compliance infrastructure, and institutional network.

The Competitors

Stellar

Stellar's strength in RWA tokenization is narrow but significant. Franklin Templeton chose it for BENJI, and Stellar's native asset issuance model does not require smart contracts, which simplifies the compliance surface. The Stellar Development Foundation has positioned the network for cross-border payments and remittance corridors, where tokenized funds can serve as settlement instruments.

Stellar's limitation is ecosystem depth. It lacks the DeFi composability, audit infrastructure, and developer tooling that Ethereum offers. Tokenized assets on Stellar tend to be isolated from secondary markets.

Avalanche

Avalanche's pitch to institutions centers on Subnets (now called L1s): customizable blockchain instances with their own validator sets and compliance rules. An issuer can deploy a permissioned Avalanche L1 where only KYC-verified participants can transact, while still bridging to the public C-Chain for liquidity.

BlackRock's BUIDL expansion to Avalanche in 2025, along with projects like Intain's structured credit platform, brought institutional attention. However, Avalanche's total RWA value remains roughly one-tenth of Ethereum's, and the subnet model fragments liquidity across isolated chains.

Solana

Solana has emerged as a surprising RWA contender. By mid-2026, Solana's RWA holder count surpassed Ethereum's for the first time, driven largely by tokenized equities and retail-facing products. State Street launched a tokenized fund on Solana in May 2026, and platforms like Solana's payment ecosystem have attracted consumer-facing tokenization projects.

Solana's advantage is throughput and cost: sub-second finality and transaction fees below $0.01 make it practical for high-frequency tokenized-asset transfers. Its limitation is institutional infrastructure. Fewer qualified custodians support Solana natively, and the smart contract audit ecosystem for Rust-based programs is thinner than Solidity's.

Are Ethereum L2s Cannibalizing Mainnet?

Ethereum's Layer 2 networks present an interesting dynamic. Arbitrum claimed the top rank in tokenized RWA deployments during H1 2026, and both Arbitrum and Base host portions of major institutional funds including BUIDL and BENJI. Robinhood launched its own Ethereum L2 built on Arbitrum in July 2026, adding a retail-brokerage distribution channel for tokenized assets.

The question is whether L2 growth represents a threat to Ethereum mainnet or an extension of its dominance. The answer, for now, is extension. Rollups like Arbitrum and Base still settle to Ethereum L1, meaning Ethereum's security guarantees underpin every tokenized asset deployed on its L2s. From a market-share perspective, trackers like rwa.xyz count L2 assets separately, which understates Ethereum's effective footprint.

Settlement layer matters: When an institution deploys a tokenized fund on Arbitrum or Base, the settlement finality still flows through Ethereum mainnet. L2 growth strengthens Ethereum's position as the settlement layer for tokenized assets, even as it shifts transaction activity away from L1.

That said, L2 fragmentation creates real challenges. A BUIDL token on Arbitrum and a BUIDL token on Optimism are not natively interoperable. Moving between L2s requires bridging, which introduces latency, cost, and smart contract risk. Standards like ERC-7683 for cross-chain intents aim to solve this, but the fragmentation problem is real and growing.

The Role of Token Standards in RWA Growth

Token standards are the quiet infrastructure that determines where institutions can practically issue. The RWA market is converging on a layered model: a base fungibility standard (ERC-20 on Ethereum, SPL on Solana), a compliance layer for transfer restrictions, and an identity layer for investor accreditation.

On Ethereum, ERC-3643 handles all three. Its ONCHAINID module provides decentralized identity verification, and the standard's transfer-restriction logic is enforced at the contract level. A newer proposal, ERC-7943 (uRWA), takes a lighter approach by focusing on wrapping any RWA token into a standardized interface. As of mid-2026, ERC-7943 was in Last Call status and had not yet reached Final.

Solana's Token Extensions (formerly Token-2022) added transfer hooks, confidential transfers, and metadata pointers that serve similar compliance purposes. However, the tooling around Solana's compliance extensions is younger, and the audit ecosystem for verifying their correctness is less developed.

What Could Shift the Balance

Ethereum's RWA dominance is real but not guaranteed. Several forces could erode its lead:

• Cost pressure: Ethereum mainnet gas fees make small-denomination RWA transactions impractical. L2s help, but add complexity. Chains with native low fees avoid the problem entirely.
• Regulatory divergence: If regulators in Asia or the Middle East standardize on non-Ethereum chains, institutional flows will follow the regulatory path of least resistance.
• Retail distribution: Solana's growing RWA holder count shows that consumer-facing tokenization may not follow the same infrastructure logic as institutional products. Retail users go where the apps are.
• Chain-agnostic issuance: Platforms like Securitize are already deploying across multiple chains. As multi-chain tooling matures, the switching cost of leaving Ethereum will decrease.

The counter-argument is that RWA tokenization is fundamentally a trust-and-compliance problem, not a throughput problem. Institutions move slowly and prefer the chain with the deepest compliance infrastructure, the most custodian support, and the longest regulatory track record. That chain is Ethereum, and that advantage compounds over time.

The Bitcoin Alternative

Ethereum dominates RWA tokenization today, but its position rests on infrastructure advantages, not on the properties of the underlying settlement layer. Bitcoin offers something that no smart contract platform can match: censorship resistance backed by the largest proof-of-work network in existence.

Taproot Assets, built by Lightning Labs, enables the issuance and transfer of arbitrary assets on Bitcoin. The protocol stores proof data off-chain while publishing standard P2TR outputs to the Bitcoin blockchain, adding token functionality without altering Bitcoin's UTXO model. Combined with Spark, which enables instant off-chain transfers with self-custody, Bitcoin-native tokenization offers a path toward RWA issuance on the most neutral settlement layer available.

For institutions that want tokenized assets to be truly censorship-resistant and settled on a base layer without governance risk, Bitcoin presents an alternative worth watching. The infrastructure is earlier-stage than Ethereum's, but the properties of the settlement layer itself are fundamentally different. Developers building in this direction can explore the Spark SDK documentation for integration details.

Conclusion

Ethereum's dominance in RWA tokenization is the product of compounding infrastructure advantages: mature token standards, deep audit tooling, universal custodian support, and years of regulatory scrutiny. These advantages created a self-reinforcing cycle that competitors have not yet broken.

But the market is shifting. Ethereum's share has declined from roughly 65% to 48% over the course of 2026 as Solana, BNB Chain, and Stellar capture new categories of tokenized assets. L2 networks like Arbitrum and Base extend Ethereum's reach while fragmenting its liquidity. And Bitcoin-native tokenization via Taproot Assets and Spark introduces a settlement layer with properties that no EVM chain can replicate. The question is no longer whether RWA tokenization will go multi-chain. It already has. The question is whether Ethereum's infrastructure moat is deep enough to keep institutions anchored as the alternatives mature.
