United Stables Launches $U as a Native Stablecoin on BNB Chain

BNB Chain today welcomes the native launch of $U, issued by United Stables, a next-generation stablecoin aiming to solve one of the biggest inefficiencies in onchain finance: fragmented stablecoin liquidity.

Stablecoins power trading, payments, and DeFi across crypto. But as more variants emerge, liquidity becomes increasingly split across assets, pools, and use cases. This fragmentation adds friction, reduces capital efficiency, and limits how programmable money can truly become.

As a stablecoin minted natively on BNB Chain, $U takes a different approach. It is designed to bring existing liquidity together, rather than competing for it. 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.

$U is the first stablecoin on BNB Chain to adopt a stablecoin-inclusive reserve model, allowing USD-backed stablecoins such as USDT, USDC, and USD1 to be used directly as minting collateral. This approach consolidates existing liquidity instead of fragmenting it further，transforming multiple stablecoins into a unified liquidity layer.

Its launch further strengthens BNB Chain’s position as one of the most active and forward-looking stablecoin ecosystems globally.

Future Upgrade: AI-Native Payments via EIP-3009 on BNB Chain

In the future, $U will natively support EIP-3009 to enable gasless, signature-based transfers. Combined with upcoming x402-enabled delegated execution, $U is designed to serve as a native payment asset for:

• AI agents and autonomous trading systems
• Automated DeFi and treasury operations
• Machine-to-machine (M2M) and programmatic payments

This direction aligns with BNB Chain’s broader focus on enabling programmable, high-frequency financial interactions, where value can move as efficiently as data.

$U as a supported asset in BNB Chain 0 Carnival Fee

$U will be added as a supported asset in the BNB Chain 0 Carnival Fee, allowing users to move and transact with zero gas fees on BNB Chain. This integration further lowers friction for onchain payments and stablecoin usage across the ecosystem.

Stablecoins on BNB Chain: A Rapidly Expanding Ecosystem

In 2025, BNB Chain continued to emerge as one of the most active stablecoin communities globally, supporting a diverse range of stablecoin models and real-world use cases.

The total stablecoin supply on BNB Chain has doubled to approximately $14 billion. The network consistently led all blockchains in monthly active addresses and transaction count for stablecoins.

Beyond mainstream USD stablecoins, the ecosystem has seen growing adoption of regional and application-specific stablecoins, including:

• BBRL, supporting Brazilian real–based payments and remittances
• USD1, designed for institution-facing settlement and treasury workflows
• USYC, offering 24/7 & near-instant redemptions into USDC 
• USDe, yield-bearing from staked assets and derivatives funding rates
• USDF, backed by assets and corresponding short future positions

These stablecoins are widely used across trading, DeFi, payments, and institutional settlement—reflecting BNB Chain’s commitment to openness, scalability, and real-world adoption.

Within this expanding landscape, $U adds a new dimension by unifying liquidity across stablecoins while introducing AI-native payment capabilities at the protocol level.
