Citadel, ARK Back LayerZero’s New ‘Zero’ Blockchain for Institutional Markets
LayerZero Labs has introduced a new blockchain network called Zero, positioning it as infrastructure for institutional-scale financial markets.
The rollout comes alongside strategic support from major financial players, including Citadel Securities, which invested in the network’s native ZRO token, and ARK Invest, which is backing both LayerZero’s equity and the token.
The company did not disclose the size of the investments, but the involvement of prominent trading firms and asset managers suggests a growing institutional push into blockchain-based market infrastructure.
Traditional Finance Steps Further Into Blockchain
Citadel Securities said it is working with LayerZero to explore how Zero’s architecture could be used to handle high-volume trading and post-trade processes. Its investment in ZRO adds to the expanding list of institutional participants showing interest in LayerZero’s technology, which already underpins one of the largest interoperability networks in crypto.
ARK Invest is also taking an active role in the project. CEO Cathie Wood will join a newly created advisory board alongside Michael Blaugrund of Intercontinental Exchange and Caroline Butler, formerly head of digital assets at BNY Mellon.
In a separate announcement earlier in the day, Tether Investments, the investment arm of the world’s largest stablecoin issuer, revealed that it had also made a strategic investment in LayerZero Labs as well.
The coordinated support from trading firms, exchanges, asset managers, and stablecoin issuers comes amid a broader shift among traditional financial institutions. After years of limited pilot programs, many are now viewing blockchain rails as potential upgrades to legacy systems for settlement, collateral management, and round-the-clock trading.
Architecture Built for High-Speed Markets
Zero is designed using what LayerZero describes as a heterogeneous architecture that relies on zero-knowledge proofs to separate transaction execution from verification. Instead of every node performing identical tasks, the network distributes workloads across specialized zones.
According to the company, this structure could theoretically support around two million transactions per second while keeping fees extremely low. The goal is to create an environment where different zones can be tailored for specific applications, such as trading engines, payment systems, or general smart contract platforms.
That is made possible through zero-knowledge proofs, which allow the network to confirm that transactions are valid without exposing sensitive data. This is a feature that could be particularly attractive for institutions handling confidential financial information.
Chief executive Bryan Pellegrino said the architecture could accelerate the industry’s development timeline significantly.
“We believe we can actually bring the entire global economy onchain with this technology,†he said.
Early Partners Point to Real-World Use Cases
Several major institutions are already exploring how Zero could be applied in real-world financial systems.
The Depository Trust & Clearing Corporation (DTCC) is evaluating the network for tokenization and collateral management projects, while Intercontinental Exchange is studying potential uses around continuous trading and tokenized collateral.
Google Cloud is also involved, working with LayerZero to explore micropayment systems and resource trading for AI agents.
At launch, Zero will include three core zones: a general-purpose Ethereum Virtual Machine environment, a privacy-focused payments network, and a specialized trading venue.
The ZRO token will be used for governance and network security, while LayerZero’s interoperability stack will connect the system to more than 165 existing blockchains.
