United Stables Launches $U Stablecoin on BNB Chain and Ethereum

United Stables has officially launched $U, a fully backed stablecoin deployed on both BNB Chain and Ethereum. The asset is designed to unify liquidity across trading, payments, DeFi, institutional settlement, and AI-driven autonomous systems. From launch, $U is integrated with major DeFi protocols and supported by leading wallets, providing immediate multi-chain access and interoperability.

What is $U and How Does It Work?

$U is a stablecoin fully backed on a 1:1 basis by a combination of cash and audited stablecoins, including USDC, USDT, and USD1. Unlike standard stablecoins, $U aggregates multiple stablecoin reserves into a single liquidity layer, allowing for improved capital efficiency and seamless cross-chain liquidity.

All reserves are stored in segregated accounts, verified through instant on-chain Proof-of-Reserve, and undergo independent quarterly audits. This ensures transparency and security for both retail and institutional users.

The stablecoin is compatible with:

• PancakeSwap
• Aster
• Four.meme
• ListaDAO

It is also supported by major wallets such as Binance Wallet, SafePal, and Trust Wallet, enabling storage, transfer, and interaction across different applications and blockchains.

Why Launch $U on BNB Chain and Ethereum?

Deploying $U on BNB Chain and Ethereum provides broad multi-chain access from the first day. Both chains are among the most widely used in the DeFi and crypto ecosystem, offering high throughput, active developer communities, and significant liquidity pools.

BNB Chain, in particular, hosts the 0 Carnival Fee program, allowing zero network fee transfers for $U, while Ethereum provides access to a wider set of institutional-grade protocols and decentralized applications.

What Makes $U Different From Other Stablecoins?

$U’s structure consolidates liquidity from multiple stablecoins into one asset. This approach transforms dispersed stablecoin reserves into a unified settlement layer suitable for multiple use cases:

• Centralized and decentralized trading
• Lending, staking, and yield strategies in DeFi
• Institutional OTC settlement and treasury operations
• Cross-border payments and remittances
• Supply chain and B2B settlement workflows
• AI-driven autonomous payment systems

$U also plans to introduce confidential balance features in the future, enabling organizations to protect sensitive financial data while maintaining transparent transaction flows for compliance and auditing purposes.

How Does $U Support AI and Autonomous Transactions?

$U is designed with the AI economy in mind. It will natively support:

• EIP-3009: Gasless, signature-based authorization for transactions
• x402-enabled delegated execution: Allows AI agents and autonomous systems to execute secure, programmable transactions

These features make $U suitable for high-frequency trading, micropayments, and machine-to-machine commerce, allowing automated systems to interact directly with the stablecoin without manual intervention.

Custody, Staking, and In-Kind Processes

Coinbase is designated as the custodian for $U, providing regulated, secure storage for the stablecoin. Bitwise and other institutional-grade providers frequently rely on such custodial solutions to ensure compliance and risk management.

The $U stablecoin also supports staking, allowing holders to lock tokens in network operations or DeFi protocols in exchange for additional rewards. In-kind creation and redemption mechanisms are planned, enabling direct token transfers for ETF-style structures or liquidity operations without cash settlement.

Stablecoin Growth on BNB Chain

The BNB Chain ecosystem has seen rapid expansion in stablecoin adoption. Total supply on BNB Chain doubled in 2025, reaching $14 billion. The ecosystem now supports both global stablecoins and regional or specialized assets such as Brazil’s BBRL and institutional USD1.

$U’s launch consolidates liquidity from these various assets, providing a unified platform for trading, payments, and DeFi interactions.

The BNB Chain team welcomed the launch, emphasizing the network’s role in stablecoin trading and payments. 

“BNB Chain has always welcomed diverse stablecoins. As one of the most active communities for stablecoin trading, we’re excited to see $U launch on BNB Chain, strengthening liquidity and powering the next wave of AI-native payments,” said Sarah S, the Head of Business Development at BNB Chain.

Additionally, the BNB Chain team’s partnership with the Better Payment Network (BPN) allows Amazon Web Services (AWS) clients to pay for cloud services using the network’s native token, BNB. 

Future Plans for $U

United Stables plans to expand $U’s ecosystem integrations over the coming months. Key future developments include:

• Confidential balances for compliance and privacy
• Additional DeFi protocol integrations
• Expanded cross-chain access beyond BNB Chain and Ethereum
• Support for autonomous AI systems and delegated execution

These initiatives aim to ensure $U remains interoperable, secure, and capable of serving both retail and institutional use cases.

Conclusion

The launch of $U on BNB Chain and Ethereum positions the stablecoin as a unified liquidity layer bridging multiple stablecoins and financial applications. With on-chain transparency, multi-chain access, and support for AI-driven transactions, $U provides a flexible, programmable solution for trading, payments, DeFi, and institutional operations.
