DUBAI — Bybit, the world’s second-largest crypto exchange by trading volume, has added support for USDT0 deposits and withdrawals on Mantle Network, making it one of the first major exchanges to enable direct cross-chain USDT0 flows. The integration positions Mantle as the largest exchange-linked Layer 2 by total value locked (TVL) and advances a unified stablecoin liquidity layer across chains.
What this enables
– Users can deposit USDT0 from Mantle directly into their Bybit accounts.
– Users can withdraw USDT0 from Bybit straight to Mantle.
– Bybit will offer zero-fee USDT0 withdrawals to Mantle for a limited promotional period.
What USDT0 is
USDT0 is Tether’s omnichain deployment of USDT built on LayerZero’s Omnichain Fungible Token (OFT) standard. It uses a mint-and-burn model to preserve a strict 1:1 backing and avoids fragmented wrapped tokens or multi-hop bridging. The goal is a single, interoperable representation of USDT that serves as a “unified liquidity layer” for wallets, exchanges, and onchain applications.
Why this matters
Bybit’s support for USDT0 on Mantle aligns centralized exchange liquidity with onchain applications and cross-chain flows. The direct mint-and-burn cross-chain design reduces routing complexity, lowers operational friction, and makes stablecoin transfers more predictable for both retail users and institutions. For traders and asset managers, it provides a straightforward on/off-ramp between exchange-held liquidity and Mantle-native DeFi or tokenized asset markets.
Mantle’s role
Mantle Network is a modular Layer 2 built on Ethereum with close ties to exchange infrastructure and a focus on liquidity distribution and real-world asset tokenization. Early support for USDT0, in coordination with Tether and Bybit, strengthens Mantle’s position as a high-performance settlement layer optimized for stablecoin flows and institutional capital. Users on Mantle can expect fast, low-cost USDT0 transfers and direct access to Bybit markets for settlement and trading.
Benefits highlighted
– One liquidity layer: USDT0 replaces fragmented wrapped variants with a single omnichain USDT.
– Native cross-chain architecture: LayerZero OFT enables direct mint-and-burn transfers between chains.
– Better user experience: Eliminates many of the multi-step bridging processes that complicate cross-chain transfers.
– Exchange integration: Bybit provides centralized liquidity, portfolio management, and direct on/off-ramps for USDT0.
Statements from partners
Mantle leadership described the move as a strategic step to reinforce the network’s role as a central venue for cross-chain stablecoin liquidity and for onchain capital markets. USDT0’s team said Mantle’s performance and Bybit’s liquidity venue help deliver a more seamless, interoperable stablecoin standard that supports wider multi-chain adoption.
Strategic context
This collaboration reflects a broader industry shift toward unified cross-chain stablecoin standards and next-generation L2s designed for high-volume capital flows. By aligning an issuer (Tether/USDT0), a high-performance Layer 2 (Mantle), and an exchange (Bybit), the integration aims to reduce fragmentation and unlock simpler rails for DeFi, tokenization, and institutional asset movement.
