Bybit launches new stablecoin support to accelerate Mantle cross-chain volume

The integration, announced on November 28, 2025, connects Bybit’s centralized order books to USDT0’s cross-chain “unified liquidity layer,” which is built on LayerZero’s Omnichain Fungible Token (OFT) standard. USDT0 uses a mint-and-burn mechanism that keeps a strict 1:1 backing with USDT and avoids the fragmented wrapped tokens and bridge risk that typically arise when stablecoins are moved across networks.

Bybit users can now send USDT0 from Mantle directly into their exchange accounts, trade against the exchange’s markets, and withdraw the same asset back to Mantle in a single step. According to the announcement, the zero-fee withdrawal window is intended to encourage early adoption of USDT0-based flows between Mantle and the exchange.

USDT0 is designed as an omnichain deployment of Tether’s USDT, serving as a single liquidity layer across supported networks rather than spawning separate wrapped versions on each chain. Transfers work via native mint-and-burn across chains, which aims to reduce operational complexity for both retail users and institutions and to cut out multi-hop bridging routes.

Mantle Network, a modular Layer-2 built on Ethereum with close ties to exchange infrastructure, is positioned in the partnership as a gateway for both institutional and retail capital into onchain markets. With USDT0 support and the Bybit integration, Mantle is described as the largest exchange-related Layer-2 by total value locked, focusing on low-cost stablecoin settlement and cross-chain flows.

The integration extends a broader collaboration between Bybit and Mantle around onchain assets and cross-chain rails. Earlier in November, the two partnered with tokenization platform Backed to bring tokenized US equities (“xStocks”) onto Mantle, with Bybit providing deposits and withdrawals between the exchange and the Layer-2. That setup uses Mantle as an execution layer for real-world assets while Bybit serves as a liquidity and access hub.

USDT0’s launch on Mantle and support on Bybit sits within a wider industry shift toward unified cross-chain stablecoin standards and tighter alignment between centralized exchanges, Layer-2 networks and DeFi protocols. Bybit also recently announced a collaboration with Taxbit aimed at strengthening tax reporting and compliance across its global and EU platforms, signaling ongoing work to connect exchange infrastructure with regulatory and onchain requirements.
