Bridging the gap: Cardano goes multichain with LayerZero

One of the most widely adopted interoperability messaging protocols in Web3 is coming to Cardano

LayerZero, the omnichain messaging protocol that connects over 160 blockchains and has facilitated over $200 billion in cross-chain volume, is integrating with Cardano. 

This is a landmark ecosystem initiative that unlocks cross-chain access to over 400 tokens, $80 billion in omnichain assets, and direct connectivity to every major blockchain ecosystem. Stablecoins, Bitcoin liquidity, the infrastructure for tokenized real-world assets, and decentralized finance (DeFi) infrastructure that were previously out of reach will become technically accessible on Cardano.

This is the single largest interoperability unlock in Cardano’s history.

Why this matters

Cardano has always been built differently. Rigorous, research-driven development. Code that’s mathematically proven to work before it ships. Cardano’s extended UTXO model, the same foundational architecture as Bitcoin, is designed for determinism, predictability, and security. These strengths are precisely why Cardano exists.

Much of the broader crypto economy uses a different design: account-based architectures. Ethereum, Solana, BNB Chain, Arbitrum, Base, and others follow this model. As a result, most cross-chain tooling has been designed primarily for account-based chains. Bridges built for EVM-to-EVM transfers don’t natively support UTXO, creating a friction layer between Cardano and cross-chain liquidity.

LayerZero is a significant unlock. Its protocol operates at the messaging layer, making it chain-agnostic by design, enabling messages to move between endpoints regardless of the underlying execution model. As with any form of interoperability, this expands what is possible without changing Cardano’s underlying approach to security, determinism, or governance.

With LayerZero, Cardano connects directly to numerous major blockchain ecosystems – Ethereum, Solana, Base, Arbitrum, BNB Chain, Sui, and over 140 more. Assets, data, and applications can move more freely between Cardano and the broader crypto ecosystem.

What gets unlocked

LayerZero’s Omnichain Fungible Token (OFT) Standard allows tokens to exist natively across multiple blockchains while maintaining a single, unified supply through a burn-and-mint mechanism. This means no traditional token wrapping, no liquidity pools sitting between you and the asset you want, and no slippage from trading against a pool. Tokens just move directly between chains, coordinated at the messaging layer.

The scale of what this opens up for Cardano is significant. More than 400 tokens, collectively worth more than $80 billion, already use the OFT Standard. These are live, production assets with billions in market cap, ready to expand to Cardano once the LayerZero Endpoint is deployed:

• Stablecoins: over 61% of all issued stablecoins are already supported by LayerZero infrastructure. Cardano gains a direct pipeline to the industry's largest stablecoin liquidity.

• Bitcoin-backed assets: wrapped BTC-denominated tokens can flow into Cardano’s DeFi ecosystem, giving the network access to Bitcoin liquidity.

• Institutional and real-world assets: tokenized equities, treasury products, and other real-world assets already on the OFT Standard become accessible on Cardano. This aligns directly with Cardano’s push toward real-world asset tokenization and institutional-grade infrastructure.

• DeFi primitives: lending protocols, yield-bearing assets, governance tokens, and liquid staking derivatives that already operate across dozens of chains via LayerZero can now plug into Cardano natively.

What this means for builders

For Cardano developers, LayerZero enables building omnichain applications using the OApp Standard, the same framework used by Ethena, PayPal, BitGo, Stargate, and hundreds of other protocols. Developers can build applications that send and receive messages, move assets, and coordinate logic across any LayerZero-connected chain. For teams building natively on Cardano, omnichain connectivity means you don’t have to choose between models. You get the benefits of EUTXO on Cardano, with the opportunity to reach account-based ecosystems beyond it.

A developer can build a lending protocol on Cardano and source collateral from Ethereum. A DEX can tap into liquidity from more than 150 networks. A stablecoin product can launch on Cardano and distribute across the broader ecosystem from day one. Throughout this, the Cardano developer experience remains unchanged. What expands is the addressable market: access to liquidity and users across the wider crypto ecosystem, regardless of the execution model on the other side.

LayerZero also brings Stargate, the largest cross-chain bridge by volume, directly to Cardano. Stargate enables seamless asset transfers between chains with unified liquidity: no fragmentation, no wrapped tokens, just native assets moving at the speed of the underlying networks.

What this means for users

For ada holders and Cardano users, this integration removes long-standing barriers that have limited what has been possible on the network. Stablecoins from other ecosystems can now be brought to Cardano without complex bridging workflows. DeFi opportunities that previously required moving to other chains become available natively. Tokens held on Cardano can flow into the broader crypto economy just as easily.

The historical borders between Cardano and the rest of crypto come down. And interoperability works in both directions.

What’s next

Cardano’s DeFi ecosystem is entering a new phase. The Cardano community has committed significant funding and resources towards critical infrastructure: stablecoins, cross-chain connectivity, custody solutions, and institutional tooling. LayerZero integration is a powerful move in its own right. Taken holistically, it becomes a game-changing component of a wider strategy, connecting Cardano to the same interoperability rails trusted by some of the largest names in crypto, financial services, and beyond.

Development will soon be underway. The integration involves deploying LayerZero Endpoint smart contracts on Cardano, with OFT-compatible token support to follow.

More details on timelines, partner launches, and developer tooling will be shared as milestones are reached.

Cardano was built to be the most secure, reliable, and censorship-resistant blockchain in the world. LayerZero expands its reach in an omnichain world.
