BNB Chain has announced the launch of $U, a native stablecoin issued by United Stables, positioning it as an infrastructure-level asset designed to streamline stablecoin liquidity across the network.
Unlike traditional stablecoins that compete for market share, $U is built with a unifying approach. Being minted directly on BNB Chain, the stablecoin focuses on aggregating existing liquidity rather than fragmenting it further — a persistent challenge in onchain finance.
“By leveraging BNB Chain’s high throughput, low transaction costs, and growing ecosystem, $U creates a more efficient foundation for both human and machine-driven finance.”
A Different Reserve Model for Stablecoins
According to the announcement, $U becomes the first stablecoin on BNB Chain to implement a stablecoin-inclusive reserve framework. This model allows established USD-backed assets — including USDT, USDC, and USD1 — to be used directly as collateral for minting $U.
This structure is intended to reduce capital inefficiencies while improving liquidity mobility across DeFi applications and payment flows within the BNB Chain ecosystem.
BNB Chain’s Expanding Stablecoin Footprint
The launch of $U comes as BNB Chain continues to strengthen its position in the stablecoin sector. Data from DefiLlama shows that BNB Chain currently ranks as the fourth-largest blockchain by total value, supported by one of the most active onchain ecosystems.
In 2025, the network has seen rapid growth in stablecoin adoption across multiple models and real-world use cases. The total stablecoin supply on BNB Chain has doubled to approximately $14 billion, highlighting increasing demand for scalable and low-cost settlement layers.
Designed for Payments, Automation, and AI
Looking ahead, $U is expected to natively support EIP-3009, enabling gasless, signature-based transfers. In combination with upcoming x402-enabled delegated execution, the stablecoin is being positioned as a foundational payment asset for AI agents and autonomous trading systems, Automated DeFi and treasury workflows, Machine-to-machine (M2M) and programmatic payments.
Zero-Gas Integration
$U will also be added as a supported asset under the BNB Chain Zero Gas Carnival initiative, allowing users to transfer and transact with the stablecoin without gas fees. This integration aims to further reduce friction for onchain payments and improve accessibility for both retail users and automated systems.
With the introduction of $U, BNB Chain continues to expand its stablecoin infrastructure, reinforcing its role as a major settlement layer for onchain finance and programmable payments.
