# Seven New Chains. One Unified Stablecoin Layer. By [StableFlow](https://paragraph.com/@stableflow) · 2026-03-20 stableflow, usdt0, stablecoins, bridge --- StableFlow is expanding USDT0 routing support to seven additional networks: Mantle, MegaETH, Ink, Stable, Celo, Sei, and Flare. This brings StableFlow’s total network coverage deeper into the long tail of chains where stablecoin liquidity has historically been thin, fragmented, or nonexistent at scale. * * * Why USDT0 matters for crosschain transfers ------------------------------------------ USDT0 is Tether’s omnichain deployment of USDT, built on LayerZero’s OFT (Omnichain Fungible Token) standard. Unlike traditional wrapped or bridged representations of USDT, USDT0 shares a single, unified liquidity pool across every supported network. There is no wrapping. No fragmentation. The same USDT moves freely between chains. For StableFlow users, this translates directly into tighter execution, lower fees, and broader reach. When USDT0 offers the most competitive route for a given transfer, StableFlow’s smart routing engine selects it automatically. Users never need to think about which rail is being used. They specify the source, the destination, the amount, and the system handles the rest. * * * What these seven chains unlock ------------------------------ Each of these networks represents a growing pocket of onchain activity where users currently face limited options for moving stablecoins in and out at scale. * **Mantle** has emerged as a major destination for DeFi capital, with deep lending and yield markets that require reliable stablecoin inflows. * **MegaETH** is pushing the boundaries of EVM throughput, attracting latency-sensitive applications that depend on fast, predictable settlement. * **Ink** (Ethereum L2 from the team that brought you Kraken) is building a bridge between CEX users and onchain activity, creating natural demand for seamless stablecoin movement. * **Stable** is purpose-built for stablecoin-native finance, making it a natural fit for StableFlow’s routing network. * **Celo**, now an Ethereum L2, continues to serve as a key rail for real-world payments and remittances across emerging markets. * **Sei** offers parallelized EVM execution optimized for trading infrastructure, where fast deposits and withdrawals are table stakes. * **Flare** is focused on cross-chain data and interoperability, with a growing stablecoin footprint that benefits from deeper connectivity. Adding USDT0 routes to each of these chains means StableFlow users can move USDT to and from these ecosystems with the same capital efficiency, low fees, and atomic settlement guarantees they already experience on Ethereum, Base, Arbitrum, Solana, and every other supported network. * * * The routing advantage --------------------- StableFlow does not rely on a single bridging mechanism. The smart routing engine evaluates every available path for a given transfer (NEAR Intents solver network, CCTP for USDC, USDT0 for USDT) and selects the route that delivers the best execution. As USDT0 expands to more chains, StableFlow’s routing surface expands with it. Moreover, StableFlow uniquely supports bridging to chains not supported by USDT0 via dynamic crosschain swaps with the NEAR Intents network. This is the compounding advantage of building on top of multiple native rails. Every new USDT0 chain integration simultaneously improves StableFlow’s coverage, pricing, and reliability without requiring users to change anything about how they interact with the product. Connect wallet, specify transfer, confirm. The routing layer handles everything underneath. * * * Where this fits in the broader picture -------------------------------------- Most bridges were designed for a world with two stablecoins on a handful of chains. That world no longer exists. StableFlow (alongside the upcoming [Stablecoin Transport Protocol](http://stablecointransport.com/)) are built for what comes next: hundreds of stablecoins across dozens of chains, all needing to move at scale with near-1:1 rates. These seven new USDT0 integrations are another step towards that goal. More chains, mortoward, better execution. The network effect continues to build. * * * About StableFlow ================ StableFlow is an intent-based liquidity network dedicated to moving stablecoins at scale. We offer a fast and secure protocol that enables effortless crosschain transfers and swaps with the best available rates and 1:1 execution.
