Mantle and Bybit Unite to Bring USDT0, the Omnichain Deployment of Tether’s USDT Stablecoin, to the Largest Exchange-Related Network

Bybit, the world’s second-largest cryptocurrency exchange by trading volume, announced support for USDT0 deposits and withdrawals on Mantle Network, becoming one of the first global exchanges to enable seamless cross-chain USDT0 flows. This integration makes Mantle the largest exchange-related Layer 2 network by total value locked (TVL). By supporting the new cross-chain standard for USDT, Mantle and Bybit are jointly positioned at the forefront of unified stablecoin liquidity infrastructure.

USDT0 is the cross-chain deployment of USDT, the largest stablecoin, serving as a “unified liquidity layer” across multiple networks. Built on LayerZero’s Omnichain Fungible Token (OFT) standard, USDT0 uses a mint-and-burn architecture that maintains a strict 1:1 backing and eliminates fragmented bridges.

With this launch, Bybit users will soon be able to:

• Deposit USDT0 from Mantle Network directly into Bybit
• Withdraw USDT0 from Bybit directly to Mantle Network
• Enjoy zero-fee USDT0 withdrawals to Mantle for a limited time

This collaboration brings together USDT0 as a liquidity infrastructure, Mantle as a leading exchange-linked L2 network, and Bybit as a global liquidity venue to help build the next phase of cross-chain stablecoin infrastructure.

USDT0 as a Unified USDT Layer

USDT0 aims to reshape stablecoin movement with:

• One liquidity layer: A single omnichain representation of USDT, not fragmented wrapped variants.
• Native cross-chain architecture: Using LayerZero’s OFT standard for direct mint-and-burn transfers.
• Simplified UX: Eliminating multi-hop bridging and complex routing for users and institutions.

Bybit’s support for USDT0 on Mantle syncs centralized liquidity, onchain applications, and cross-chain flows into a cohesive experience, giving users more predictable and efficient access to Tether-based liquidity.

Mantle as a Leading Exchange-Connected Network for USDT0

Mantle Network is a modular Layer 2 built on Ethereum, with deep ties to exchange infrastructure and a focus on distribution and liquidity for tokenized assets and real-world finance. Being among the first exchange-related networks to support USDT0 early, alongside Tether & Bybit, reinforces Mantle’s positioning as:

• A high-performance L2 optimized for stablecoin settlement and cross-chain flows.
• A gateway for exchange liquidity and institutional capital entering onchain ecosystems.
• A hub for DeFi, tokenization, and RWA markets built on stable, programmable collateral like USDT0.

For users, this means:

• Fast, low-cost USDT0 transfers on Mantle.
• Direct access to Bybit markets using USDT0 as a settlement and liquidity asset.
• Streamlined deployment of capital into Mantle-native applications.

“Supporting USDT0 early, together with Tether and Bybit, is a strategic step for Mantle,” said Emily Bao, Key Advisor at Mantle. “It strengthens Mantle’s role as a core venue for cross-chain stablecoin liquidity and the onchain capital markets that depend on it.”

“USDT0 was designed to unify liquidity across chains, and Mantle’s high-performance infrastructure makes it an ideal network for this vision,” said Lorenzo R., Co-Founder at USDT0. “Working alongside Bybit and Mantle enables us to deliver a more seamless, interoperable stablecoin standard that improves UX and accelerates multi-chain adoption for users and institutions alike.”

Improving Onchain UX and Capital Movement

USDT0 is designed to make stablecoin flows feel more intuitive and direct:

• More efficient cross-chain liquidity movement
• Reduced operational friction for both retail and institutional users
• Stronger alignment between centralized exchange rails and onchain destinations

Bybit’s integration adds:

• A centralized liquidity hub for USDT0 trading and portfolio management
• Direct on/off-ramps between Mantle and Bybit
• Free withdrawals during the initial rollout to encourage early adoption

Strategic Importance for Tether, Mantle, and Bybit

The early alignment across all three parties reflects a broader industry shift toward:

• Cross-chain stablecoin standards that unify rather than fragment liquidity
• Next-generation L2 infrastructure designed for high-volume capital flows
• Integration between issuers, exchanges, and high-performance networks
• Infrastructure required for DeFi, tokenization, and institutional-grade asset movement

With USDT0 now live on Mantle and will soon be available on Bybit, the ecosystem takes a major step toward a borderless, frictionless stablecoin standard that will underpin the next era of onchain finance.
