Supported Ecosystems

Supported Chains for DUSD0

DUSD0 is designed to operate across a curated selection of leading Layer 1 and Layer 2 blockchains, enabling omnichain liquidity for Delta’s decentralized digital dollar, DUSD. These networks are selected based on performance, security, adoption, and composability with the broader DeFi ecosystem. Through direct minting or interoperability with Delta’s Liquidity Grid, DUSD0 ensures capital efficiency and seamless user experiences across ecosystems.

Native Minting Chains

Supported Native Chains for DUSD0 Minting

Native DUSD0 liquidity is initially minted on three foundational blockchains, ensuring high security, scalability, and efficient accessibility across diverse decentralized ecosystems:

1

Ethereum (ERC-20)

Ethereum serves as the origin chain for DUSD0 issuance. Known for its robust security model and high composability, Ethereum remains a foundational layer for institutional deployment and large-value transactions. This ensures that DUSD0 liquidity remains secure, transparent, and accessible to a wide range of decentralized applications and protocols.

2

BNB Chain (BEP-20)

BNB Chain is a high-throughput Layer 1 blockchain selected for its scalability, cost-efficiency, and widespread adoption. Serving as an alternative minting environment for DUSD0, BNB Chain enables greater user accessibility, especially in global retail and institutional sectors, while offering lower transaction costs compared to Ethereum.

3

Solana (Native SPL)

Solana further enhances DUSD0's liquidity capabilities by enabling native minting of DUSD0 through native SPL tokens. As a high-performance, non-EVM blockchain, Solana offers high-speed transaction processing and low costs, making it an ideal choice for enabling DUSD0 liquidity in fast-growing decentralized ecosystems that prioritize scalability and throughput.

These chains host the fully collateralized DUSD0 reserves that back all DUSD0 tokens across the omnichain network. By utilizing native minting on these foundational chains, DUSD0 ensures that liquidity is secure, transparent, and readily available for cross-chain transfer and utilization in a variety of decentralized finance environments.

Omnichain Deployments via OFT Standard

Networks Compatible with DUSD0

DUSD0 is deployed using the Omnichain Fungible Token (OFT) standard powered by LayerZero, allowing native and trustless interoperability between supported chains. These include:

1

Base

A Coinbase-incubated Layer 2 offering low fees and fast finality, optimized for consumer-facing DeFi applications.

2

Berachain

An EVM-compatible Layer 1 tailored for institutional-grade DeFi infrastructure and native incentive alignment.

3

Arbitrum

A leading Ethereum rollup known for its deep liquidity and robust protocol integrations.

4

Mantle

A modular Ethereum Layer 2 offering high performance and gas efficiency, backed by a robust ecosystem treasury.

5

Optimism

An L2 focused on open innovation, scalability, and retroactive public goods funding.

6

Sonic

A next-generation parallelized Layer 1, purpose-built for high-speed execution, modular scaling, and seamless composability with Ethereum tooling.

Each of these chains is integrated into the DUSD0 architecture via a lock-and-mint mechanism, maintaining 1:1 parity with underlying DUSD on Ethereum or BNB Chain, and ensuring consistency of value and availability.

Liquidity Grid Integration

For chains without native DUSD minting, Delta utilizes the Delta Liquidity Grid, a proprietary interchain routing framework that allows DUSD liquidity to flow seamlessly across networks. This enables secure, non-custodial transfers between native and non-native chains, while avoiding the risks and inefficiencies of traditional bridging mechanisms.

Chains such as Solana and Berachain are connected to this grid through OFT messaging layers and audited liquidity pools, allowing users to mint and redeem DUSD0 tokens with confidence.

Expansion Strategy

As the ecosystem evolves, DUSD0 will continue to expand to high-impact blockchains that meet Delta’s security, liquidity, and governance criteria. All new chain integrations will be subject to internal audits, third-party reviews, and ecosystem alignment assessments. This ensures that the DUSD0 network grows responsibly and remains fully interoperable and institutionally compliant.
