Chain Distribution of Tokenized Fund AUM
The $11.70B tokenized fund market distributes across multiple blockchain networks, with Ethereum commanding dominant market share at 59%. This analysis maps product-specific chain distribution, enabling investors to understand where fund assets reside and how chain selection affects access, costs, and composability.
AUM Distribution by Chain
Ethereum (59% of RWA Market)
Primary chain for: BUIDL (majority of $2.01B), USYC ($2.40B), OUSG (primary), syrupUSDC ($1.75B, Ethereum-only), BENJI (newest deployment), USTB (Ethereum-only).
Ethereum hosts the vast majority of tokenized fund AUM because: institutional infrastructure is Ethereum-first (Securitize, Anchorage, Fireblocks), DeFi composability is deepest (Flux Finance for OUSG), and institutional investors prefer Ethereum’s security track record. See Ethereum dominance analysis.
Stellar
BENJI original and primary chain. Low transaction costs, built-in compliance features. Estimated $400M+ in BENJI AUM on Stellar.
Solana
OUSG and USDY deployed on Solana. Growing DeFi ecosystem attracting crypto-native investors. Estimated $666.8M in Ondo product AUM on Solana.
EVM Layer 2s (Arbitrum, Optimism, Polygon)
BUIDL multi-chain deployment includes Arbitrum, Optimism, and Polygon. BENJI on Polygon. Lower gas costs enable smaller position management. Combined estimated $300M+ in Layer 2 AUM.
Avalanche
BUIDL deployed on Avalanche C-Chain. Targeting Avalanche’s institutional DeFi ecosystem.
Aptos, Mantle, Sui
Emerging chains with Ondo product deployment. Early-stage AUM, primarily targeting next-generation blockchain ecosystems.
Detailed Chain Analysis
Ethereum Mainnet: The Institutional Settlement Layer
Ethereum hosts approximately $5.7B of the $11.70B tokenized fund market — the largest concentration on any single chain. This dominance stems from several structural factors documented in the Ethereum dominance analysis:
Infrastructure Depth: Securitize (SEC-registered transfer agent for BUIDL), Anchorage Digital (OCC-chartered custodian), Fireblocks (MPC custody), and Coinbase Prime (institutional exchange) are all Ethereum-first. This creates a self-reinforcing cycle where institutional infrastructure attracts institutional capital, and institutional capital attracts more infrastructure.
DeFi Composability: Flux Finance (for OUSG leverage), USDY DEX pools on Uniswap and Curve, and Maple Finance lending pools operate exclusively or primarily on Ethereum. The DeFi integration guide maps composability by chain.
Security Budget: Ethereum’s proof-of-stake consensus, secured by $100B+ in staked ETH, provides the highest economic security of any blockchain — critical for products managing billions in institutional capital.
Cost Trade-Off: Ethereum mainnet transactions cost $5-15, making small-scale operations expensive. However, for institutional-scale transactions ($100K+), gas costs are negligible relative to position value. A $10M BUIDL subscription costs ~$8 in gas — 0.00008% of the transaction value.
Stellar: The Compliance-First Alternative
Franklin Templeton chose Stellar for BENJI’s original deployment, representing approximately $400M+ in tokenized fund AUM. Stellar’s appeal for regulated fund products includes built-in compliance features (asset issuance controls, clawback capability, trustlines), sub-cent transaction costs ($0.00001 per transaction), 3-5 second finality, and a regulated-friendly ecosystem with SDF (Stellar Development Foundation) engagement with regulators.
However, Stellar’s minimal DeFi ecosystem limits BENJI’s composability — no equivalent of Flux Finance exists on Stellar, and DEX liquidity is shallow compared to Ethereum. Franklin Templeton has expanded BENJI to Polygon and Ethereum to address these limitations while maintaining the original Stellar deployment for cost-sensitive users.
Solana: High-Performance Chain for DeFi-Native Products
Ondo Finance deployed OUSG and USDY on Solana, capturing approximately $666.8M in combined AUM. Solana’s appeal includes high throughput (~4,000 TPS), sub-cent transaction costs, 400ms block times enabling near-instant settlement, and a growing institutional DeFi ecosystem (Marinade, Jupiter, Raydium).
Institutional concerns about Solana center on historical network outages (2022-2023) that temporarily froze all on-chain activity including tokenized fund operations. While reliability has improved significantly in 2024-2025, the historical record creates hesitancy among risk-averse institutional allocators who cannot tolerate periods where fund tokens are untransferable.
EVM Layer 2s: Ethereum Security at L2 Cost
BUIDL’s multi-chain deployment across Arbitrum, Optimism, and Polygon, plus BENJI on Polygon, represents approximately $300M+ in combined L2 AUM. The L2 proposition is compelling: same token, same NAV, same yield, same issuer backing, but with 10-100x lower transaction costs.
Arbitrum: Optimistic rollup settling proofs on Ethereum mainnet. BUIDL’s Arbitrum deployment provides institutional-grade access at $0.10-0.50 per transaction. Growing institutional DeFi ecosystem (Aave, Uniswap deployments).
Optimism: Optimistic rollup with similar security properties to Arbitrum. BUIDL deployed here alongside the broader OP Stack ecosystem.
Polygon: Proof-of-stake sidechain (transitioning to zkEVM). BUIDL and BENJI both deployed on Polygon, providing the broadest tokenized fund product selection of any L2.
Avalanche: Institutional Subnets
BUIDL deployed on Avalanche C-Chain, targeting Avalanche’s institutional DeFi ecosystem and its unique subnet architecture. Subnets allow institutions to create custom blockchains with configurable validator sets and compliance controls — appealing for regulated products that require controlled environments. Securitize supports Avalanche deployment for all its tokenized products.
Aptos, Mantle, and Emerging Chains
Ondo has deployed USDY on Aptos and other emerging chains, targeting next-generation blockchain ecosystems. Aptos’s Move programming language provides formal verification capabilities for financial applications. These deployments are early-stage (estimated <$100M combined AUM) and represent positioning for future growth rather than current institutional adoption.

Chain Selection Framework for Investors
Product availability varies by chain. Selecting the right chain depends on three factors:
Factor 1 — Product Availability: Ethereum provides the broadest product selection (all major products). Stellar is exclusive for BENJI’s original deployment. Solana serves Ondo products. Layer 2s offer cost-efficient BUIDL access.
Factor 2 — Transaction Cost Sensitivity: For positions under $100K with monthly rebalancing, L2s or Solana reduce gas friction. For positions above $1M, Ethereum mainnet gas is negligible. The fee analysis quantifies gas impact by position size.
Factor 3 — DeFi Integration Needs: Ethereum mainnet offers the deepest DeFi composability. OUSG leverage via Flux Finance is Ethereum-only. USDY DEX pools are deepest on Ethereum. syrupUSDC is Ethereum-only.
Factor 4 — Custody Provider Support: The custody solutions guide details chain support across providers. Fireblocks supports all major chains. Anchorage focuses on Ethereum. BitGo supports Ethereum and select L2s.
Multi-Chain Strategy and Cross-Chain Considerations
Investors holding tokenized fund products across multiple chains must manage cross-chain complexity: separate wallet management per chain, bridging risks if transferring tokens between chains, and chain-specific gas token requirements (ETH for Ethereum, SOL for Solana, MATIC for Polygon). The multi-chain deployment analysis provides strategic guidance for multi-chain positioning.
Chain Security and Settlement Finality
For institutional investors managing billions in tokenized fund products, chain security is not merely a technical consideration — it is a fiduciary obligation. The security budget of each chain determines how resistant it is to reorganization attacks that could reverse fund token transfers.
Ethereum Security Budget: Ethereum’s proof-of-stake consensus mechanism is secured by approximately $100B+ in staked ETH. Attacking Ethereum would require controlling 33% of staked ETH for finality disruption — approximately $33B at current prices. This economic security makes Ethereum the most secure smart contract platform and explains why 59% of all tokenized fund AUM resides on Ethereum mainnet. The SEC has acknowledged Ethereum’s commodity status, providing regulatory clarity that reinforces institutional confidence.
Solana Security Trade-offs: Solana’s proof-of-stake and proof-of-history consensus provides high throughput but with a smaller validator set and lower total stake value compared to Ethereum. The historical network outages in 2022-2023 — while resolved in subsequent upgrades — created institutional hesitancy. For Ondo products deployed on Solana, the trade-off is clear: lower transaction costs and faster settlement versus lower economic security and historical reliability concerns.
Layer 2 Security Inheritance: Arbitrum, Optimism, and Polygon derive security from Ethereum mainnet through different mechanisms. Optimistic rollups (Arbitrum, Optimism) post transaction data to Ethereum with a 7-day challenge window. ZK rollups (Polygon zkEVM) generate cryptographic proofs verified by Ethereum. Both approaches provide Ethereum-level security guarantees while reducing transaction costs by 10-100x — making them increasingly attractive for tokenized fund deployment.
Future Chain Distribution Projections
The chain distribution of tokenized fund AUM will likely shift over the next 2-3 years as Layer 2 infrastructure matures and new blockchain ecosystems attract institutional capital. BlackRock’s multi-chain BUIDL deployment signals that the world’s largest asset manager views multi-chain distribution as strategically important. As additional products follow BUIDL’s multi-chain approach, Ethereum mainnet’s 59% share may decline to 40-50% while Layer 2 chains collectively grow to 20-30% of total AUM.
The data tracked by RWA.xyz shows the broader RWA market at $20 billion across 55,520 treasury holders, with chain-level data revealing growing traction on chains beyond Ethereum. This multi-chain expansion creates both opportunity (broader access, lower costs) and complexity (fragmented liquidity, cross-chain bridge risk) for tokenized fund investors.
Chain Selection Criteria for Institutional Allocators
Institutional investors evaluating tokenized fund products across multiple chains should apply a structured chain selection framework that accounts for security, liquidity, regulatory positioning, and operational requirements.
Security Threshold: Institutional positions exceeding $10M should be deployed on chains with economic security exceeding 100x the position value. For Ethereum (security budget $100B+), positions up to $1B meet this threshold comfortably. For smaller chains with lower staking value, large positions may represent a material percentage of chain security — creating theoretical attack incentives that, while unlikely, violate institutional risk management principles.
Liquidity Requirements: Chain selection should account for on-chain stablecoin liquidity. A BUIDL holder on Arbitrum needing to redeem to USDC requires sufficient USDC liquidity on Arbitrum. Ethereum mainnet has the deepest stablecoin pools ($30B+ USDC), while L2s and alternative chains have thinner liquidity that could create friction for large redemptions.
Custody Infrastructure: Not all institutional custody providers support all chains equally. Fireblocks and Anchorage Digital provide full custody support for Ethereum and major EVM chains but may have limited support for newer chains (Aptos, Sui). Allocators should verify that their custody provider supports the specific chain before deploying. The custody solutions guide maps custody provider chain support.
Regulatory Clarity: The SEC has provided the most regulatory clarity for Ethereum-based digital assets (commodity classification, ETF approvals). Tokens on other chains may face different or uncertain regulatory treatment. For compliance-sensitive allocators, Ethereum deployment offers the safest regulatory positioning. The regulatory classification analysis covers chain-level regulatory considerations.
Gas Cost Impact on Chain Selection Economics
For institutional positions, gas costs on Ethereum mainnet ($5-15 per transaction) are negligible — representing less than 0.001% of a $10M transaction. However, for smaller positions and frequent rebalancing, L2 chains reduce gas costs by 10-100x. A BUIDL holder rebalancing monthly on Ethereum mainnet pays approximately $60-180 annually in gas, versus $1-18 on Arbitrum or Optimism. This cost differential becomes material for positions under $100K, where gas on mainnet can reduce effective annual yield by 5-15 basis points. The fee analysis quantifies gas impact by position size and chain. The SEC has acknowledged that transaction costs affect investor returns, though blockchain-specific gas costs are not yet addressed in standardized fee disclosures. The counterparty assessment evaluates how issuer chain selection decisions reflect operational capability and institutional infrastructure quality across the broader tokenized fund ecosystem and growing institutional market.
