Proposal: [UNICHAIN] Add Support for USD₮0 Market on Venus Core Pool

Summary

Add support for the USD₮0 market on Venus Core Pool

Background

About USD₮0

USD₮0 is a bridged version of Tether’s USDT stablecoin, designed to extend USDT’s availability to blockchains where it is not natively issued. It operates on a “lock-and-mint” mechanism, meaning that USDT is locked on Ethereum while an equivalent amount of USD₮0 is minted on the destination chain. This system is powered by LayerZero’s Omnichain Fungible Token (OFT) standard, which facilitates secure and seamless cross-chain transfers.

USD₮0 is managed by Everdawn Labs and represents a standardized approach to expanding Tether assets to new blockchains. The protocol’s mission is to make Tether the de-facto asset issuer on every chain, ensuring USDT maintains its position as the most widely accessible stablecoin across all blockchain ecosystems.

How USD₮0 Works

USD₮0 operates through a sophisticated yet simple mechanism:

1. Assets: USDT gets locked in a smart contract on Ethereum Mainnet
2. Issuance on Destination Chains: Equivalent USD₮0 tokens are minted on the destination chain, reflecting the locked amount
3. Transfers: Users can move USD₮0 across supported chains without worrying about liquidity, leveraging LayerZero
4. Redemption: USD₮0 tokens can be redeemed by unlocking the corresponding USDT on Ethereum, from any supported chain, always maintaining a strict 1:1 backing

The LayerZero OFT standard ensures that USD₮0 maintains a 1:1 backing with USDT on Ethereum, and transfers are validated by a decentralized security model involving oracles and relayers. This approach reduces the complexity of cross-chain transactions while enhancing liquidity management.

Benefits

Integrating USD₮0 as collateral on Venus Core Pool will offer several benefits:

1. Deep Liquidity

USD₮0 will significantly improve liquidity and trading volumes on Venus, providing users with seamless access to Tether’s stablecoin without the need for fragmented bridging solutions. The omnichain nature of USD₮0 ensures consistent liquidity across all supported networks.

2. Increased Yield Opportunities

With Venus supporting USD₮0 as collateral in the Core Pool, users can unlock greater capital efficiency by leveraging their USD₮0 holdings. This integration drives higher potential returns from lending and borrowing activities, particularly for stablecoin strategies and cross-chain arbitrage opportunities.

3. Innovative DeFi Strategies

The integration paves the way for the development of advanced DeFi strategies involving USD₮0 and other assets. Users can benefit from:

• Cross-chain yield farming opportunities
• Efficient stablecoin arbitrage strategies
• Enhanced liquidity management across multiple networks
• Seamless integration with LayerZero ecosystem protocols

SuperStacks Incentive Program

To mark the launch, Venus users can earn SuperStacks rewards by lending USD₮0. By participating in SuperStacks, users benefit from:

1. Unique Multipliers: Special reward multipliers for USD₮0 activities
2. Cross-chain benefits: Earn rewards that can be utilized across the entire USD₮0 ecosystem
3. Integration Rewards: Additional incentives for early adopters who provide liquidity
