$Proshares Ether Strategy ETF(EETH.US)

1 Event Summary

In early April 2025, the world's largest custodian bank BNY Mellon announced the launch of the on-chain tool Digital Asset Data Insights, starting to broadcast the Net Asset Value (NAV) of its funds daily to the Ethereum mainnet via smart contracts. The first user was BlackRock's BUIDL USD Digital Liquidity Fund. Although the data types are currently limited to NAV, the symbolic significance is immense as it marks the first step onto a public blockchain by a financial infrastructure giant with approximately $53.1 trillion in total assets under custody.

2 Authenticity Verification

Conclusion: Cross-verified from multiple sources, the event is confirmed and already operational in a production environment.

3 How "Digital Asset Data Insights" Works

1. On-chain Endpoint: BNY or its authorized parties deploy a read-only smart contract on Ethereum.
2. Signed Payload: The official NAV value is signed daily by the fund accounting system and uploaded to the chain, forming an event log.
3. Data Consumption: Portfolio dashboards, risk engines, and DeFi protocols can directly call or listen to events, achieving second-level data retrieval.
4. Off-Chain and On-Chain Data Homogeneity: The announcement emphasizes that on-chain NAV has the same legal validity as traditional FTP/SWIFT pipeline data, meeting audit and compliance requirements.

4 Strategic Significance for Traditional Custodians

5 Latest Progress in Institutional Asset On-Chainization

1. BlackRock BUIDL — The first tokenized money market fund issued on Ethereum in March 2024, with AUM reaching $1.92 billion.
2. State Street — Plans to launch tokenized collateral and bond products by 2026 and has partnered with Taurus to accelerate RWA on-chain.
3. JPMorgan Onyx / TCN — Uses Ethereum-derived Roll-up for inter-institutional collateral settlement.
4. HSBC Orion — Issues digital bonds on permissioned chains, allowing cross-chain bridging to ERC-20 environments.

Trend: First, mirror ledger data (BNY → NAV), then tokenize the assets themselves, and finally bridge private Roll-ups to meet privacy and throughput needs.

6 Will Custodians Build Their Own L2 or Private Roll-ups?

Realistic Assessment: BNY has not yet announced an L2 plan; it is expected to first pilot in closed-loop environments (permissioned Roll-ups) before bridging to public L2s, depending on compliance progress.

7 Vitalik’s "World Computer" Vision and RISC-V Proposal

• 2025-04-09 Hong Kong Web3 Carnival: Vitalik reiterated that "Ethereum's ultimate goal is to be a world computer," emphasizing L1/L2 synergy.
• 2025-04-21: Proposed replacing EVM with RISC-V to reduce zero-knowledge proof overhead by 50–100×.
  • If implemented within 2-3 years, it could significantly increase L1 throughput and weaken competing chains' pure performance advantages.
  • For custodians, lower Roll-up costs would enhance the commercial feasibility of "writing accounting or asset actions to the chain."

8 Insights and Milestone Observations

1. First-Mover Example: BNY's on-chain NAV is confirmed, marking the first formal integration of a public blockchain with a globally systemic institution.
2. Technical Building Blocks: With on-chain accounting oracles in place, the next steps of tokenization and real-time settlement become significantly easier.
3. Path Dependency Lock-in: Each traditional institution that embeds itself in Ethereum increases the friction of migrating to other L1s.
4. Short-Term Indicators to Watch:
   • When BNY will add more data (e.g., shareholder registries, dividend records).
   • Regulatory sandboxes allowing the issuance of on-chain Fund Class C shares.
   • Multiple custodians collaborating to build privacy Roll-ups with proofs anchored to Ethereum L1.

9 Conclusion

The event is confirmed and far-reaching.
BNY Mellon has begun broadcasting regulated fund NAVs daily to Ethereum via Digital Asset Data Insights, initially serving BlackRock's BUIDL fund. Though a small step, it lays the foundation for a financial pillar with over $53 trillion in custody assets to engage with open networks, lowering the psychological and compliance barriers for traditional finance to embrace public blockchains. If follow-up projects like tokenization and private Roll-ups progress, a large-scale institutional on-chain financial stack based on Ethereum's security will take shape, also laying the groundwork for future digital economy scenarios like RWA and AI agent settlements.
