DUBAI, Nov. 27, 2025 — Bybit, the world's second-largest crypto exchange by trading volume, announced support for USDT0 deposits and withdrawals on Mantle Network. Bybit is among the first global exchanges to enable seamless cross-chain USDT0 flows. The integration makes Mantle the largest exchange-related Layer 2 network by total value locked (TVL).
How USDT0 Works
USDT0 is the cross-chain deployment of Tether's USDT, acting as a unified liquidity layer. Built on LayerZero's Omnichain Fungible Token (OFT) standard, it uses a mint-and-burn architecture that maintains strict 1:1 backing and eliminates fragmented bridges. Users no longer need multi-hop bridging or complex routing.
Benefits for Bybit Users
With the launch, Bybit users can deposit USDT0 from Mantle directly into Bybit, withdraw USDT0 from Bybit to Mantle, and enjoy zero-fee USDT0 withdrawals to Mantle for a limited time. Bybit's integration syncs centralized liquidity, onchain applications, and cross-chain flows into a cohesive experience, giving users more predictable access to Tether-based liquidity.
Strategic Alignment
Mantle is a modular Layer 2 built on Ethereum with deep ties to exchange infrastructure. Being among the first exchange-linked networks to support USDT0, alongside Tether and Bybit, reinforces Mantle's role as a high-performance L2 for stablecoin settlement and capital flows. Mantle said: "Supporting USDT0 early is a strategic step. It strengthens Mantle's role as a core venue for cross-chain stablecoin liquidity." Tether added: "USDT0 unifies liquidity across chains. Working with Bybit and Mantle delivers a more interoperable stablecoin standard."
The early alignment reflects a broader shift: unified cross-chain stablecoin standards, next-gen L2 for high-volume flows, and integration between issuers, exchanges, and high-performance networks. USDT0 is now live on Mantle and will soon be available on Bybit.
