Appendix I
Benefits of LayerZero Protocol
Application-Owned Security Model
LayerZero v2 introduced Decentralized Verifier Networks (DVNs), offering tailored security for cross-chain messaging. Any participant can operate their own DVN for interoperability, ensuring the security of their assets and other Canton issued asset transfers and have the ability to establish themselves as a trusted option for other third parties in the Canton network. Alternatively, participants can integrate existing DVNs to optimize cross-chain message verification based on specific requirements such as security, cost, and speed. Over 40 DVNs are currently available, including those operated by Google, Blockdaemon, Polyhedra, LayerZero Labs, and many others. There are also adapter DVNs for Chainlink CCIP and other decentralized validation mechanisms if desired.
Omnichain Fungible Tokens (OFTs) and Omnichain Applications (OApps) leverage LayerZero’s modular security framework, enabling Canton participants to select their own verification methods for token transfers, as the application owner. This flexibility allows application owners to alter verification methods as desired, utilizing oracles, bridges, chain validators, or any suitable verification mechanism.
For further details on DVNs and their functionality, refer to the provided link.
Figure 4: Sample of DVN Providers
Pathway Ownership
As the application owners, Canton participants have full autonomy of wiring and un-wiring cross-chain pathways for their applications. The application needs to set peers for the sender application address with each destination LayerZero Endpoint ID and the associated receiver application address. Owners of the contract can turn on and off their set peers whenever they want, providing them the ability to connect and disconnect the ability for users to transfer assets and communicate. The LayerZero protocol, nor LayerZero Labs, has any ability to turn on or off an application set peers.
Universal Composability
OFTs introduce standardization to token operations across various chains. Traditional tokens are often constrained by the rules and standards of their native blockchain, resulting in a fragmented experience when interacting with multiple chains. In contrast, OFTs maintain a consistent standard across all chains they operate on. This uniformity streamlines the user and developer experience, as the token behaves identically regardless of the blockchain used.
Such standardization is invaluable for both developers and users, as it diminishes the complexity and learning curve associated with managing assets across multiple chains. Integration of the OFT Standard can keep token addresses consistent across all chains, simplifying the process for developers and market makers. This feature can significantly reduce the time and resources needed for product managers to incorporate blockchain technology into existing systems.
Unified Liquidity
OFTs unify liquidity across networks through fast and secure communication between contracts via burn and mint (user or application initiated). This eliminates the need for wrapped assets (4/5 largest exploits have occurred with wrapped assets) and liquidity on multiple chains for bridging via standalone asset pools, paving the way for scalable liquidity across numerous L2s and L1s. In terms of efficiency, OFTs exist as native tokens on each chain, requiring only gas fees for transfer, devoid of additional costs associated with wrapping, bridging, or slippage. OFTs can be natively transferred across any LayerZero Labs supported chains (currently 124) in a point to point flow, without ever needing to redeem on any one base chain, e.g. Ethereum.
Inventory Management
OFTs are essential tools for facilitating seamless multi-chain asset management. These tokens enable fast, native transfers across chains, streamlining deposits and withdrawals across any blockchain where they're deployed, eliminating reliance on third-party bridges and reducing settlement times - a critical advantage for effective inventory rebalancing. The unified supply across all chains simplifies the extension to new blockchains, broadening access to diverse ecosystems rapidly, when needed.
Moreover, OFTs optimize liquidity management across different blockchains and exchanges efficiently. The ability to transfer tokens freely negates the necessity for maintaining fragmented inventories across chains. Market makers can centralize their token reserves, deploying them as needed to capitalize on arbitrage opportunities or to provide liquidity, enhancing market stability and efficiency by being able to seamless rebalance across chains via burn and mint without having to wait multiple day escrow periods that are inherent to native bridges going to and from L2s.

PayPal's PYUSD stablecoin, has gained significant traction in DeFi with a market capitalization exceeding $0.5 billion. A major driver of its growth has been its integration into DeFi protocols, particularly on the Solana and Ethereum blockchains. PYUSD has found notable use in liquidity pools. Additionally, platforms offer attractive yields on PYUSD, contributing to its adoption. PYUSD is regulated under the NYDFS and currently LayerZero is the only interoperability protocol approved by the regulator for cross-chain composability and designed on behalf of PayPal, a regulatory compliant solution for cross-chain transfer.
USDT0 Team collaborated with LayerZero to co-build complete interoperability across new chains (via the new USDT0 asset and OFT Standard) and existing chains (via the USDT Legacy Mesh powered by LayerZero messaging).
BitGo’s Wrapped Bitcoin (WBTC), a tokenized form of Bitcoin on the Ethereum blockchain, currently holds a market capitalization of around $14 billion, with over 148,000 WBTC in circulation. Its Total Value Locked (TVL) in DeFi exceeds $10 billion. WBTC allows Bitcoin holders to participate in Ethereum-based DeFi applications, including lending, borrowing, and yield farming. It is widely integrated into major DeFi protocols for lending, liquidity provisioning, and stablecoin swapping. LayerZero has enabled BitGo to expand WBTC to BNB, Base, Sei and Avalanche within two weeks of engineering work and plan to expand WBTC to Uni and Movement before the end of 2024.
Ondo Finance's USDY token, backed by U.S. Treasuries, currently has a market capitalization of approximately $384 million. The total value locked across its products exceeds $600 million, with USDY contributing the largest share. This yield-bearing stablecoin is integrated into major decentralized finance (DeFi) ecosystems, and is used in applications for liquidity provisioning, lending, and other DeFi functionalities. LayerZero is actively working with Ondo to bring USDY to Mantle, Ethereum, Arbitrum, Solana and Aptos. USDY operates under Regulation S of the SEC. More detail on their LayerZero implementation can be found in their documentation here.
Ethena adopted LayerZero’s OFT standard to expand USDe, sUSDe, and ENA across 10 ecosystems, achieving over $2 billion in cross-chain transaction volume. USDe’s rapid growth highlights LayerZero’s ability to facilitate scalable, compliant, and efficient cross-chain movement, with built-in security features such as blacklisting and controlled access mechanisms ensuring seamless asset management.
JP Morgan, WisdomTree and Apollo worked with LayerZero in Project Guardian. LayerZero facilitated seamless cross-chain messaging across two portfolios of digital assets via the OApp standard. This collaboration is changing how traditional finance interacts with blockchain, enhancing liquidity, efficiency, and security across platforms.

- toggle quoted message Show quoted textDear all,As discussed during the last tokenomics committee meeting, we do not want to offer exclusivity or "default" anything status for external services like this where several providers can coexist. Basically any and all mentions of "default" anything or exclusivity need to go.I also want them to include sources for their claims of transaction volume, etc.Regarding the weight, I propose that we bring it down to 2.5 to make it consistent with the weight assigned to the cross chain bridging part of the Chainlink CIP and offer a "bonus" of 1.5 to the first SV to bring cross chain bridging to Canton. By incorporating this "bonus" idea from Eric we should be able to get a working implementation of cross chain bridging sooner and potentially two of them.Best regards,Fernando2025年5月7日(水) 5:20 DrAmandaLMartin via lists.sync.global <amartin=linuxfoundation.org@...>:Hello,
