Supported staking protocols and integrations

DUO Protocol Overview

DUO Protocol integrates with established, high-liquidity staking and DeFi platforms to aggregate multiple yield streams while maintaining security, composability, and full liquidity.

Current Integrations

DUO’s restaking layer is currently deployed exclusively on Arbitrum (Layer 2), leveraging Ethereum Layer 1 as the settlement layer for security. Within this deployment, DUO integrates the following external protocols:

• Lido Finance (wstETH) — primary staking source for ETH, providing the base staking rewards used in DUO’s restaking layer.

• 0Fx Protocol — the central protocol of the 0Fx ecosystem, acting as the primary unit of account and value anchor for ecosystem applications.

• Aurex — a collateralized lending and leveraged trading platform that receives liquidity from DUO. This liquidity deployment generates additional interest income on top of base staking rewards, without compromising DRST liquidity.

All staking operations, including wstETH sourced from Lido, are executed and managed via Arbitrum for scalability and low fees, while remaining anchored to Ethereum Layer 1 for settlement security.

Integration Priorities

The initial focus is to launch restaking products for the most recognized and widely used market assets, ensuring DUO provides yield solutions suitable for all investor profiles.

Multi-Chain Roadmap

While DUO is currently available exclusively on Arbitrum, its architecture supports future multi-chain expansion. Deployment to other chains or layers will depend on:

• User demand and liquidity depth

• Asset availability and yield opportunities

• Security and composability requirements

For assets native to a specific chain or layer, DUO will prioritize native restaking deployments to preserve yield efficiency over wrapped or bridged alternatives.
