# Omnichain Infrastructure

## **A Unified Standard for Cross-Chain DUSD Mobility**

**DUSD0** is the **omnichain extension** of **DUSD**, Delta’s **decentralized dollar**, purpose-built to **unify liquidity** across the most advanced **DeFi ecosystems**. Leveraging **LayerZero’s OFT (Omnichain Fungible Token)** protocol, DUSD0 enables **seamless** and **secure movement** of DUSD between blockchains — without relying on **wrapped assets**, **synthetic tokens**, or **third-party bridges**.

This framework delivers the **capital efficiency**, **composability**, and **trust** required by **institutional-grade applications** and protocols, ensuring **DUSD** remains **universally accessible** across the expanding **multichain environment**.

## **Where Base Liquidity Is Held**

All **DUSD0 tokens** are fully backed by **native DUSD liquidity**, which is **transparently held and locked** on **Ethereum**, **BNB Chain**, and **Solana** — the original **issuance networks** for DUSD. These **reserves** form the base of DUSD0’s **lock-and-mint architecture**, ensuring that every **cross-chain transfer** is secured by **real, auditable value**.

This design guarantees **1:1 redemption** and **native parity** across all connected environments, while maintaining **high standards of transparency** and **risk management**.

## **Strategic Chain Integrations for Scalable Liquidity**

**DUSD0** is currently deployed across a **growing suite** of **performance-optimized blockchains**. Supported environments include both **EVM** and **non-EVM networks**, ensuring **interoperability without compromise**. These chains are selected for their **technical resilience**, **liquidity depth**, and **developer ecosystem strength**.

| **Chain/Platform**                   | **Type**                           | **Description**                                                   |
| ------------------------------------ | ---------------------------------- | ----------------------------------------------------------------- |
| **Ethereum (ERC-20)**                | Core minting layer / Reserve chain | Core minting layer and primary reserve chain                      |
| **BNB Chain (BEP-20)**               | EVM Layer 1                        | High-throughput alternative minting venue                         |
| **Solana (SPL)**                     | Non-EVM Layer 1                    | Native minting through SPL tokens                                 |
| **Plasma**                           | Bitcoin sidechain, EVM-compatible  | Engineered specifically for stablecoins                           |
| **Hyperliquid  (HyperEVM)**          | EVM Layer 1                        | High-performance blockchain                                       |
| **Berachain**                        | Custom EVM Layer 1                 | Purpose-built for native DeFi liquidity                           |
| **Base, Arbitrum, Optimism, Mantle** | EVM Layer 2s                       | Optimized for scalable DeFi                                       |
| **Sonic**                            | Layer 1 (EVM)                      | High-speed chain with parallelized execution and instant finality |

Each of these networks plays a distinct role in **DUSD distribution** and **omnichain operability** — supporting institutional capital movement, seamless protocol integration, and the expansion of Delta’s unified stablecoin framework.

## **Enabling the Future of Omnichain Liquidity**

**DUSD0** is more than a **cross-chain extension** — it is a **foundational primitive** for the **next generation of decentralized financial infrastructure**. By **anchoring liquidity** to **trusted base layers** and **extending access** across **high-performance chains**, DUSD0 ensures that **DUSD** can move wherever **capital is needed**, without compromising on **trust**, **transparency**, or **technical integrity**.

As **DeFi** continues to **fragment across chains**, **DUSD0 unifies**, enabling a **scalable** and **secure liquidity standard** for **institutions**, **protocols**, and **builders** at the frontier of **multichain finance**.
