# 1. Project Overview
United Stables ($U) is a USD-pegged stablecoin project issued by United Stables Limited (registered in the British Virgin Islands), designed to serve as a unified liquidity layer for stablecoins, connecting fragmented liquidity across exchanges, DeFi, payment networks, and AI-driven systems. The project emphasizes the seamless flow of value between humans and AI, supporting trading, payments, institutional settlements, and autonomous systems. $U operates on the BNB Chain, with a circulating supply equal to its maximum supply, which is unlimited. The project has integrated with platforms such as Binance, Venus Protocol, and Cobo, and will launch zero-fee trading pairs on Binance on January 13, 2026.
# 2. Project Introduction
United Stables aims to address the fragmentation issue in the current stablecoin market by creating a unified liquidity layer that connects different ecosystems. The project positions itself as the next-generation stablecoin, supporting a variety of application scenarios from trading to AI autonomous systems, including global market base currency, on-chain yield generation, institutional settlements, cross-border payments, and machine-to-machine commerce. It adopts an inclusive reserve model for stablecoins, accepting fiat and trusted stablecoins as reserves to accelerate minting and unify liquidity. The project emphasizes inclusivity, catering to users from developing countries to Silicon Valley, as well as human and AI agents, supporting privacy-enhancing features and programmable money. By sharing ecological rewards with partners, the project aims to build an open global financial network that fosters collective growth.
# 3. Products and Technology
The core product of $U is a stablecoin backed 1:1 by fiat currency (USD) and high-quality stablecoins, with reserves held in isolated, auditable custody. Key features include gas-free transfers (enabled by EIP-3009), support for gas payments on TokenPocket, and zero-fee trading pairs for U/USDT and U/USDC on Binance. Technically, it is based on the BNB Chain and integrates PancakeSwap (v2, v3, v4 CLAMM) and Uniswap v4. The project supports AI-ready programmable features for autonomous trading and machine-to-machine commerce, as well as enterprise-grade privacy-enhanced confidential balances. Institutions can mint using fiat or stablecoins after KYB verification, while users can lend and earn yields through DeFi platforms like Venus Protocol.
Additionally, $U adopts the "stablecoin pool" concept: only mainstream USD stablecoins with the highest market depth and most comprehensive audits (USDT, USDC, USD1) are whitelisted as collateral. On-chain contracts scan prices and supply daily, automatically rebalancing weights to ensure that underlying assets remain highly liquid and risk-diversified. The integration of AI scenarios is embedded at the protocol layer: through EIP-3009 and x402 agent payments, AI models can complete gas-free micropayments in milliseconds; developers can preset "on-chain budgets" for each AI address, automatically shutting down when the limit is exhausted to prevent infinite charges; after the launch of the zero-knowledge balance interface, AI enterprises can prove "sufficient U to complete transactions" to external parties without disclosing specific amounts, balancing compliance and commercial privacy.
# 4. Economic Model
- Issuance Mechanism
The smart contract only mints the corresponding amount of U upon receiving USD or whitelisted stablecoins; when redeeming, the contract destroys U and returns USD or stablecoins, with the entire process recorded on-chain to ensure that the circulating supply ≤ reserve amount.
- Fee Structure
Minting is free; on-chain transfers incur standard gas fees; a 0.1% fee is charged for redemptions, which is fully injected into the insurance fund for extreme situations.
- Insurance Fund
The target size is 1% of the circulating supply, with funding sources from redemption fees, node penalty revenues, and partner rebates; when the reserve ratio <100% and cannot be immediately replenished, the fund can be used to purchase gap assets.
- Governance Mechanism
Currently, the United Stables board is responsible for parameter adjustments (whitelisted assets, fee rates, insurance fund caps, etc.), with plans to transition to a dual-layer governance model in Q4 2026: institutional nodes will form a "consensus committee" responsible for reserve management, and token holders will be able to vote on fee rate adjustments and asset whitelisting.
# 5. Team and Investors
- Core Team
There is limited public information; the official disclosure states that core members come from traditional banking clearing, crypto custody, and payment gateway fields, with the CTO having previously worked in the cross-border payment department of SWIFT and JPMorgan.
- Investors
No public funding rounds have been seen; based on CZ's social media following and BNB Chain's official preheating, the market speculates that Binance / YZi Labs provides strategic support, but this has not been officially confirmed.
- Custodian Partner
Ceffu (formerly Binance Custody) is responsible for cold storage of on-chain assets; on the banking side, Wallet Trust Limited, registered in Bermuda, acts as the trustee to achieve bankruptcy isolation.
# 6. Roadmap
Q1 2026 – Launch on the Ethereum mainnet, open institutional whitelisting for minting; – Release mobile SDK to support one-click integration for gas-free transfers in wallets.
Q2 2026 – Integrate Polygon and Arbitrum, achieving interoperability across four chains; – Launch "Instant Swap" feature, allowing users to swap U with USDC/USDT at a 1:1 zero slippage within the same contract.
Q3 2026 – Launch enterprise privacy balance testnet, inviting the first batch of hedge funds and payment companies; – Collaborate with Visa on a crypto card, launching U physical cards that support 80 million merchants globally.
Q4 2026 – Transition to hybrid DAO governance, open node applications; – Target circulating supply of 1 billion, with reserve fund size reaching 10 million USD.
# 7. Risks and Opportunities
On the opportunity side, $U enhances accessibility and efficiency through zero-fee trading integration with Binance and gas support from BNB Chain, potentially achieving expansion in DeFi and AI systems. The unified liquidity model can attract institutional and retail users, providing low-cost cross-border payments (below 1.5%) and on-chain yield opportunities. The integration of AI opens new applications for autonomous systems and machine commerce. Risks include typical challenges for stablecoins, such as reserve asset volatility, liquidity fragmentation, and regulatory uncertainty (the project is not registered under MiCA, Hong Kong stablecoin regulations, or U.S. law). Additionally, reliance on partner ecosystems may introduce integration risks, while unlimited supply may affect long-term stability.
# 8. Conclusion
United Stables ($U) is positioned as an innovative stablecoin project focused on unifying fragmented liquidity and supporting applications in the AI era, building a sustainable network through 1:1 reserves and ecological incentive mechanisms. Although it shows strong performance in technology and products, details about the team and roadmap are limited, which may require further observation of its execution and regulatory compliance progress. The project's early integration within the BNB Chain ecosystem shows potential, but inherent risks in the stablecoin market must be weighed.
