lzAsset is chain expansion as a service for token asset issuers. LayerZero deploys and manages pre-native token versions across 150+ chains using the Omnichain Fungible Token (OFT) architecture, providing immediate composable liquidity with a seamless upgrade path when issuers enable native minting.

​

Overview

lzAsset leverages LayerZero’s OFT contracts to expand native assets to new blockchains using a repeatable, future-proof architecture. The service acts as a universal liquidity rail with point-to-point interoperability, unlocking distribution at scale with on-demand liquidity. Once a chain is connected, asset issuers can access pre-native versions of their assets through lzAsset. For example, the native asset USDG becomes the pre-native asset for USDG0. Each pre-native token is fully backed 1:1 by the native asset and aligns with issuer standards (such as Circle’s Bridged USDC Standard) for contract ownership takeover by the asset issuer. All pre-native asset supply can be redeemed for the native asset on any chain with a native asset deployment.

​

Architecture

lzAsset uses a two-mesh system that separates issuer-controlled deployments from LayerZero-managed infrastructure:

​

Native mesh

The asset issuer deploys and controls their standard OFT implementations across selected chains. These are the sanctioned deployments that the issuer directly manages, maintains upgrade authority over, and configures security settings for.

​

lzAsset mesh

LayerZero deploys and manages corresponding pre-native OFT implementations (e.g., USDG0, PYUSD0, AUSD0) across all supported chains. These contracts are maintained by LayerZero Labs with security configurations, DVN selection, and operational management handled as a service.

​

Hop composer

The two meshes interoperate through a hop OFT Adapter that enables transfers between native and pre-native versions. Users can deposit native tokens into the adapter, which mints equivalent lzAsset tokens that can then travel across the lzAsset mesh. Conversely, users can redeem lzAssets for native tokens on any chain where native deployments exist. Security isolation: The only funds at risk are those deposited in the hop OFT Adapter. The pre-native mesh is fully backed 1:1, and all lzAsset supply can be redeemed for native assets. This architecture limits exposure while enabling broad distribution.

​

How it works

lzAsset is a collection of existing OFT standards working together with a Composer on the Hub Chain to route transfers between Native and lzAsset chains.

​

Core Contracts

​

On lzAsset chains

OFT Mint & Burn: Implements an OFT with mint and burn capabilities. This architecture enables a point-to-point mesh where spoke chains transfer directly to one another by burning lzAssets at the source and minting them at the destination, without routing through a hub. The contract manages access control (minter/burner roles) for security.

​

On Hub Chain

OFT Adapter: Uses a Lock/Unlock pattern (Lockbox) to hold native tokens in escrow. This adapter locks assets when sending to the lzAsset mesh and unlocks them when receiving, serving as the bridge between the native and pre-native ecosystems. Hop Composer: A contract that orchestrates messaging between the Native Mesh and the lzAsset Mesh. It receives composed messages, decodes destinations, and routes packets. It also ensures robustness with permissionless refund (return to source) and retry (re-execute with higher gas) mechanisms for failed transactions.

​

On Native Chains

OFT Mint & Burn: The standard Mint/Burn pattern deployed by the asset issuer. These contracts are fully controlled by the issuer and interoperate with the lzAsset mesh via the Hub Chain’s Composer.

​

Transfer Flows

​

Within the lzAsset mesh (Direct)

User sends tokens from one lzAsset chain to another

1. Source: Burn tokens and sends LayerZero message
2. Destination: Mint tokens to recipient

All spoke chains are wired point-to-point, enabling direct transfers without routing through the hub.

​

Between meshes: Native → lzAsset (Routes through Hub)

User sends tokens from a Native chain to an lzAsset chain

1. Native: Burn tokens and sends LayerZero message to Hub Chain
2. Hub: OFT Lockbox locks native tokens and triggers compose
3. Hub: Hop Composer routes to the lzAsset chain and sends LayerZero message to lzAsset chain
4. lzAsset: Mint tokens to recipient

​

Between meshes: lzAsset → Native (Routes through Hub)

User sends tokens from an lzAsset chain to a Native chain

1. lzAsset: Burn tokens, sends LayerZero message to Hub Chain
2. Hub: OFT Lockbox unlocks native tokens, triggers compose
3. Hub: Hop Composer routes to Native chain and sends LayerZero message to Native Chain
4. Native: Mint tokens to recipient

​

Value proposition

​

For asset issuers

Rapid expansion: Deploy to 150+ chains without building and maintaining infrastructure for each chain. LayerZero handles deployment, security configuration, monitoring, and operational maintenance. Compliance alignment: Pre-native deployments follow established standards for contract ownership transfer, enabling issuers to take over deployments when ready to enable native minting on new chains. Operational simplicity: No ongoing maintenance required. LayerZero manages bridging, routing, rebalancing, and protocol upgrades automatically. Brand protection: Pre-native tokens clearly indicate their status (e.g., USDG0) while maintaining association with the native asset. When issuers enable native minting, every lzAsset balance seamlessly upgrades 1:1 to the native asset.

​

For chain owners

Immediate liquidity: Launch with day-one access to deep, interoperable liquidity across LayerZero’s network, already trusted for over $100B in bridge volume. No need for incentive programs or bootstrapping. Trusted assets: Users interact with familiar, fully-backed stablecoins and RWAs from day one. Pre-native versions maintain full backing and redeemability. Instant composability: DeFi protocols can immediately build lending markets, DEX pairs, and payment systems using trusted assets. All lzAssets implement the IOFT interface for unified integration. Eliminates cold-start problem: New chains receive standardized, composable liquidity without waiting for individual asset issuers to deploy. Chains become attractive deployment targets for DeFi protocols from launch.

​

Benefits

​

Immediate liquidity

Unlock day-one access to deep, interoperable liquidity across LayerZero’s 150+ supported chains. Asset issuers can instantly scale to meet demand anywhere liquidity flows. Chains receive trusted assets that users already know and protocols can immediately integrate.

​

Future proof

Stablecoins grew from approximately $27B market cap in 2020 to over $250B by mid-2025, representing the fastest-growing asset class in crypto. lzAsset positions both issuers and chains to capture the next wave of tokenized value on efficient, programmable rails.

​

Instant trusted composability

Access fully-backed stablecoins such as USDG0, PYUSD0, and AUSD0 across issuer-selected chains with zero slippage. Mint, burn, and redeem from the deepest liquidity hubs. DeFi protocols can instantly build on top of these assets, and all transfers use LayerZero’s security-first approach with configurable DVN verification.

​

Operational simplicity

lzAsset handles bridging, routing, rebalancing, and token upgrades automatically. Asset issuers connect once to LayerZero and inherit a fully managed, security-audited liquidity rail with zero ongoing maintenance required. Chain operators receive battle-tested infrastructure without deployment complexity.

​

Upgrade path

When asset issuers enable native minting on a chain currently served by lzAsset:

1. Seamless transition: Every lzAsset balance automatically becomes redeemable 1:1 for the native asset
2. No user action: Holders don’t need to swap, bridge, or manually upgrade their tokens
3. Smart contract transition: The issuer can take over the pre-native deployment contract following established standards for ownership transfer
4. Maintained liquidity: All existing integrations continue working through the IOFT interface

This upgrade path ensures that early adopters and DeFi protocols building on pre-native assets face no disruption when issuers expand their native deployment strategy.

​

Current adopters

​

USDG0

Backed by native USDG, Paxos’ regulated stablecoin backed by the Global Dollar Network (including Robinhood, Kraken, Mastercard, and others). USDG0 is available pre-natively via the Stargate Finance Hydra offering, giving blockchain ecosystems day-one access to compliant USD liquidity.

​

PYUSD0

Backed by native PayPal USD (PYUSD), a regulated stablecoin issued by Paxos. Bridges Web2 fintech rails with Web3 applications to expand stablecoin utility across payments and DeFi.

​

AUSD0

Collateralized by U.S. Treasuries, AUSD provides instant stablecoin liquidity and powers Citrea’s Bitcoin-based applications with secure, yield-backed collateral.

​

Chain partners

lzAsset pre-native tokens are available across LayerZero’s network of 150+ chains, including major L1s, L2s, and emerging blockchain ecosystems. The service provides chains with immediate access to trusted, composable liquidity without requiring individual negotiations with each asset issuer.

1. Contact business development: Email bd@layerzerolabs.org with details about your chain and liquidity needs
2. Technical integration: Ensure your chain supports LayerZero Endpoint deployment (EVM, Solana, Aptos, Sui, or other supported VMs)
3. Asset selection: Work with LayerZero to identify which lzAssets best serve your ecosystem
4. Launch coordination: LayerZero handles deployment, security configuration, and integration with the existing lzAsset mesh

​

For DeFi developers

If you’re building on a chain with lzAsset tokens:

1. Review IOFT interface: All lzAssets implement the standard LayerZero token interface
2. Use existing integration patterns: Integrate once, support all LayerZero assets including lzAssets, native OFTs, and Stargate tokens
3. Plan for native transition: Design integrations that continue working when lzAssets upgrade to native

​

Technical implementation

lzAsset tokens are standard OFT implementations managed by LayerZero Labs. From a technical perspective, they function identically to any other OFT:

• Implement the IOFT interface for transfers
• Support composed messages via lzCompose() for DeFi integration
• Use LayerZero DVNs for verification and Executors for delivery
• Maintain unified supply across all chains through burn/mint mechanics
• Provide fee quoting via quoteSend() for accurate cost estimation

The key difference is operational: LayerZero handles deployment, security configuration, and maintenance rather than the asset issuer.

​

Security model

​

Isolation through architecture

The hop OFT Adapter is the only point where native assets are held. This limits exposure to the adapter contract rather than the entire lzAsset mesh. All pre-native supply is backed 1:1 by assets in the adapter.

​

LayerZero security

All transfers use LayerZero’s security infrastructure:

• DVN verification: Multiple independent verifiers confirm message validity
• Executor delivery: Separate delivery mechanism from verification
• Configurable security: LayerZero Labs configures appropriate DVN requirements for each lzAsset

​

Audited infrastructure

lzAsset uses battle-tested OFT contracts that have processed billions in volume. The same contracts power Stargate Hydra and numerous independent OFT deployments across the LayerZero ecosystem.

​

Comparison with alternatives

​

lzAsset vs. deploying your own OFT

​

lzAsset vs. Stargate Hydra

Both use similar OFT architecture for extending liquidity. Stargate Hydra focuses on established deep liquidity assets (USDC, USDT, ETH) managed through StargatePool and StargateOFT contracts. lzAsset focuses on stablecoin and RWA issuers who want their brand represented across chains with a clear path to native deployment ownership.
