LayerZero is an interoperability protocol that enables developers to create omnichain applications (OApps) that work seamlessly across multiple blockchains. Positioned as an infrastructure layer where "finance and the internet converge," LayerZero makes tokens and applications compatible with various blockchain types. [28] As of early 2026, the protocol connects over 165 blockchains, secures over $95 billion in assets, and is utilized by more than 750 applications. [28][29] LayerZero was founded by Caleb Banister, Bryan Pellegrino, and Ryan Zarick in 2021. [1][2][3]
LayerZero is a messaging protocol, not a blockchain. It facilitates seamless interaction between blockchains using smart contracts on each chain, Decentralized Verifier Networks (DVNs), and Executors. Implemented on January 29th, 2024, LayerZero V2 separates message verification and execution, giving developers more control over security and execution. It also offers enhanced message throughput, programmability, and other contract-specific improvements, making it a more flexible and efficient messaging protocol. [11]
The update includes Decentralized Verification Networks (DVNs), which replace the V1 Oracle and allow any entity capable of verifying cross-chain data packets to join LayerZero, promoting decentralization. In March 2026, Worldpay and Global Payments launched a "Payments DVN" on LayerZero, providing an enterprise-grade security solution for verifying cross-chain payment transactions across nine blockchains, including Ethereum and Solana. [30] Adapters for Axelar and CCIP DVNs are available on testnet and will be on mainnet at launch, with additional adapters planned for 2024 to support various native bridges, third-party bridges, middle chains, oracles, and other verification methods, preventing vendor lock-in. The X of Y of N Verification feature provides a modular approach, enabling applications to customize their security by choosing a combination of DVNs, thus optimizing costs and security levels based on specific needs. [11]
Permissionless Execution introduces Executors, a new role that handles execution on the destination chain separately from verification, simplifying gas payments and offering customizable gas settings. Each application must configure a Security Stack comprising DVNs, Executors, chain confirmations, MessageLibraries, and chain pathways, granting full control over security settings. Increased throughput is achieved by offering lazy or strict nonce enforcement options, allowing developers to choose between in-order or out-of-order transaction execution, thereby aligning LayerZero’s throughput with the destination chain’s while maintaining censorship resistance. [11]
Enhanced programmability is facilitated by improved protocol contract interfaces, path-specific libraries, new design patterns, and horizontal composability, fostering flexibility and uninterrupted cross-chain transactions. Unified semantics ensure that applications function uniformly across all blockchains with LayerZero endpoints, including non-EVM chains. Finally, the V2 launch supports forward and backward compatibility, aiding teams building on V1. [11]
Ultra Light Node (ULN) is a novel cross-chain bridging and messaging approach. ULN combines the security of on-chain light nodes with the cost-effectiveness of middle chains. On-chain light nodes receive and validate every block header for each pairwise chain on the opposing chain, making it the most secure way to transmit messages between chains, but it comes with a high cost. Middle chains, on the other hand, are less secure but more cost-effective. [4]
ULN solves this dilemma by performing the same validation as an on-chain light node, but instead of keeping all block headers sequentially, block headers are streamed on demand by decentralized oracles. This eliminates the need for a node to store every block header, reducing the storage and computational overhead and making it a more cost-effective solution. The oracles are incentivized to provide accurate and reliable block headers, ensuring the security of the messages transmitted between chains. [4]
LayerZero addresses the limitations of existing cross-chain networks, which often suffer from sparse connectivity and inconsistent communication interfaces, by providing a uniform and densely connected mesh network across all supported blockchains. An Omnichain Mesh Network allows any chain to communicate with any other chain directly using a predictable and stable interface, facilitating seamless data and value transfer across blockchains. The LayerZero protocol maintains consistent security and reliability across all connections, despite varying security semantics and design logic among individual blockchains. [14]
The network ensures uniform standards for packet delivery, reliable data transfer without censorship, and packets are delivered exactly once to their intended destinations. LayerZero's modular security model offers configurable and non-configurable security guarantees, allowing developers to choose the security and cost-efficiency models that best fit their applications. Decentralized Verifier Networks (DVNs) verify messages and can be configured by applications, while configurable block confirmations protect against block reorganizations on the source chain. Core security features, such as protection against censorship, replay attacks, and unauthorized code changes, are built into the network's immutable interfaces. [14]
The network recognizes that each pathway might require a different security configuration. Pathways, defined by source blockchain, source application, destination blockchain, and destination application, can be individually configured to tailor security and cost to the specific needs of each connection. This chain-agnostic approach enables developers to create Omnichain Applications (OApps) that operate seamlessly across blockchains. [14]
The LayerZero Endpoint is an immutable smart contract providing a standardized interface for Omnichain Applications (OApps) to manage security configurations and send and receive messages seamlessly. A LayerZero Endpoint is divided into four modules: Communicator, Validator, Network, and Libraries. The Communicator, Validator, and Network modules make up the core functionality of the endpoint, while new chains are added as additional Libraries. This design allows for easy support of new chains without modifying the core modules. [3][15]
LayerZero is a blockchain infrastructure that provides a range of utilities to developers and users. Its key features include a cross-chain decentralized exchange, multi-chain yield aggregator, and multi-chain lending. These utilities allow for seamless transfer of native assets across different chains, access to high-yield opportunities, and cost-efficient lending options. [15]
LayerZero facilitates a cross-chain decentralized exchange (DEX) that operates solely with native assets. Unlike traditional DEX designs that use wrapped tokens or go through intermediary sidechains, LayerZero enables DEXs with liquidity pools on both chains, allowing users to deposit their native assets on one chain and withdraw native assets from another. With LayerZero's messaging capabilities, direct bridges, automated market-making, and other pricing models can be implemented. [15]
When using LayerZero for cross-chain transactions, a multi-chain yield aggregator could tap into the high-yield opportunities across multiple ecosystems, maximizing access to high-yield opportunities and allowing users to take advantage of market inefficiencies. This would be an improvement over single-chain yield aggregators that restrict their access to yield opportunities outside of their current ecosystem and instead would provide more yield opportunities to choose from. [15]
Multi-chain lending on LayerZero allows users to take advantage of opportunities on different chains while consolidating their assets on their preferred chain. Through a lending protocol, users can lend their assets on their preferred chain and borrow the desired asset directly on another chain, eliminating the need for costly intermediary steps like bridge and swap fees. [15]
LayerZero's Omnichain Fungible Token (OFT) standard is a framework for creating tokens that can be transferred across multiple blockchains while maintaining a single, unified supply. [22] [23] Unlike traditional cross-chain bridges that "wrap" tokens—creating a separate, synthetic version on the destination chain—the OFT standard utilizes a burn-and-mint mechanism. When a user transfers an OFT, the token is burned on the source chain, and an equivalent amount is minted on the destination chain. This process avoids the liquidity fragmentation and security risks associated with wrapped assets. [22] [24]
The OFT standard is particularly advantageous for stablecoins, as it helps maintain their peg and ensures consistent liquidity across different ecosystems. By eliminating wrapped tokens and the need for liquidity pools in transfers, it avoids slippage and price inconsistencies between chains. [22] Issuers also retain control over their assets, as their own smart contracts manage the mint-and-burn logic. They can also configure their own security through Decentralized Verifier Networks (DVNs). [24]
The OFT standard has been adopted by major players in the stablecoin space. In November 2024, PayPal's stablecoin, PYUSD, integrated the OFT standard to enable seamless transfers between Ethereum and Solana. This allows PYUSD holders to move their assets between the two networks without relying on centralized platforms or third-party bridges, with security managed by a DVN chosen by the issuer, Paxos. [24] [22]
In January 2025, Tether partnered with LayerZero to launch USDT0, a cross-chain version of its USDT stablecoin using the same standard. Debuting on Kraken's layer-2 blockchain, Ink, USDT0 is designed to unify liquidity and has facilitated over $70 billion in cross-chain value transfers in the 12 months leading up to February 2026. [25] [31] The standard was further adopted in October 2025 for KRWQ, the first multi-chain stablecoin backed 1:1 by the Korean Won. Developed by IQ in partnership with Frax, KRWQ utilizes LayerZero's OFT technology to operate as a unified asset across various blockchains, launching initially on the Base network. [36]
The standard has also been adopted for the public sector. In 2025, the state of Wyoming launched "FRNT," the first U.S. state-backed stable token, built on LayerZero to ensure sovereign control and compliance across seven blockchains. [32]
The OFT standard is also used for tokenized assets. In September 2024, BitGo, the custodian for Wrapped Bitcoin (WBTC), chose LayerZero as its interoperability provider to expand WBTC to chains like BNB Chain and Avalanche. [26] Tokenized real-world asset protocol Ondo Finance used the OFT standard to launch its yield-bearing stablecoin, USDY, on networks including Solana in November 2024, making it fungible across different blockchain ecosystems. [27]
In March 2026, a partnership with Centrifuge was announced to integrate its institutional-grade real-world asset (RWA) infrastructure with LayerZero. This allows asset managers to issue tokenized funds on Centrifuge and extend their reach across all LayerZero-connected chains, with initial products including JTRSY, JAAA, and SPXA. [29]
In June 2025, Skate, a project focused on creating a unified multi-chain execution ecosystem, integrated Stargate's LayerZero OFT for its native SKATE token. This integration allows the SKATE token to move across multiple blockchains, including Ethereum, Arbitrum, and Solana, enhancing its liquidity and accessibility for dApp interoperability. The use of the OFT standard ensures that transfers are cost-effective and have zero slippage. [23]
On June 14, 2024, the LayerZero team introduced the 'LayerZero Foundation'. [16] The foundation's stated mandate is to promote the decentralization of the LayerZero protocol and support the growth of its ecosystem and community. It oversees governance activities, including a ZRO token buyback program and protocol fee switch proposals. [33] Also, Bryan Pellegrino, the CEO of LayerZero Labs, released his calculations on the ZRO token airdrop in a tweet on X;
Ok let's talk some numbers.23.8% of the supply is going directly to the community and builders. This does not include foundation, growth, etc. Directly to community. 8.5% of this is being distributed day 1 (5% core, 3% RFP, 0.5% community pool) The majority of the remainder will be given over the next 36 months with additional retroactive distribution every 12 months, along with some forward looking RFPs for builders.... - he tweeted on June 14, 2024 [12]
Per the tweet, ZRO has a supply of 1 billion, of which 23.8% is reserved for allocation to community and builders. 23.8% excludes foundation, growth, and other heads. 8.5% of the tokens allocated to the community and builders will be distributed on the first day of the airdrop; the rest will be allocated within three years. The project plans an additional allocation every 12 months, and some forward-looking Request for Proposals (RFPs) will be provided for builders in the ecosystem. [13]
LayerZero Labs also mentioned June 20 as the airdrop date for the token while asking users to determine their eligibility status via the official website. [17]
LayerZero has established partnerships across institutional finance, enterprise payments, and government sectors.
On April 1st, 2021, LayerZero raised $2 million as their first-ever seed funding round. [2][18]
On September 16th, 2021, LayerZero's series A funding round, led by Binance Labs and Multicoin Capital, raised $6 million. Additional investors included Sino Global Capital, Defiance, Delphi Digital, Robot Ventures, Spartan, Hypersphere Ventures, Protocol Ventures, Gen Block Capital, and Echelon Capital. [2][5]
On March 20th, 2022, LayerZero's series B funding round was led by a16z, FTX, and Sequoia, raising $135 million. Some of the main investors included Coinbase Ventures, PayPal Ventures, Tiger Global, and Uniswap Labs. [6][7]
In February 2026, Tether Investments announced a strategic investment of an undisclosed amount into LayerZero Labs. The investment was made to support LayerZero's work in building its interoperability protocol and was cited as a sign of confidence in its technology as critical infrastructure for the digital asset space. [31]
On February 10, 2026, LayerZero Labs introduced Zero, a new blockchain architecture described as the first decentralized "multi-core world computer." [34] Zero is designed to function as a high-performance, sharded blockchain that can scale horizontally to achieve internet-scale throughput while maintaining decentralization and permissionless access. It is positioned as a distinct product alongside LayerZero's interoperability protocol. [35]
Zero's architecture is built on a heterogeneous model that decouples transaction execution from verification using Zero-Knowledge (ZK) proofs. This separation allows for two classes of validators: high-performance Block Producers that execute transactions and generate proofs, and lightweight Block Validators that run on consumer hardware to reach consensus by verifying those proofs. [34]
The system scales horizontally through "Atomicity Zones," which are parallel execution shards, each functionally equivalent to a single EVM instance. The protocol is designed to run hundreds of these zones simultaneously, with new zones added through on-chain governance. A specialized "System Zone" manages core protocol functions, including the native ZRO coin, staking, and governance processes. [35]
Zero's performance relies on four key technological innovations designed to address major blockchain bottlenecks: [35]
Zero utilizes a Pure Delegated Proof of Stake (PDPoS) consensus mechanism, where security comes entirely from delegated stake, and validators are not required to provide a self-stake. To encourage decentralization, there is no consensus-layer slashing for downtime or misconfiguration, and staking rewards are distributed proportionally to all honest participants. [35]
Governance is managed through a "Senator Model," where ZRO stakers can delegate their voting power to recognized experts in relevant fields. Delegators retain full control and can override their Senator's vote at any time. All protocol upgrades, including the creation of new Atomicity Zones, are handled through a formal on-chain governance process. [35]
In August 2025, LayerZero acquired the cross-chain protocol Stargate for $110 million. [20] The acquisition followed a competitive bidding process where LayerZero's offer was chosen over proposals from several rivals. [19]
The bidding war saw interest from other major interoperability protocols. Wormhole submitted a competing bid of 10 million higher than LayerZero's offer. [20] [19] Additionally, Axelar Network and Across Protocol signaled their interest in acquiring Stargate, though the process moved forward with LayerZero's proposal. [19] [21]
The acquisition was approved by the Stargate community DAO in a vote where 95% of participants favored the deal. [20] [19] Following the vote, the Stargate DAO was officially dissolved. [20] This acquisition brought Stargate, which was originally developed and launched by LayerZero in 2022, back under its control, aligning the bridge's future development with LayerZero's strategic vision. [19]
In April 2026, a major exploit involving infrastructure connected to LayerZero resulted in approximately $290–$292 million in losses from a cross-chain bridge used by Kelp DAO. [37]
The attack targeted a bridge supporting rsETH, a liquid restaking token issued by Kelp DAO. Reports indicate that the attacker drained approximately 116,500 rsETH, representing roughly 18% of the token’s circulating supply. [38]
According to multiple reports, the exploit involved forging a cross-chain message within the bridge’s communication system. This caused the bridge to incorrectly validate a transaction and release funds to an attacker-controlled address.
Further analysis suggested that the bridge relied on a 1-of-1 Decentralized Verifier Network (DVN) configuration, meaning a single validator was responsible for approving cross-chain messages.
This created a single point of failure that enabled the forged message to be accepted. [37][38]
Kelp DAO implemented emergency measures shortly after the exploit, including pausing contracts and freezing core systems.
These actions prevented additional unauthorized withdrawals, including two subsequent attempts that could have resulted in further losses of up to $100 million. [37]
