How to buy Union (U)

How to buy and use Union (U) on its native network

Union (U) is a cryptocurrency launched in 2025 that operates on the Ethereum platform. It is designed for interoperability and utilizes zero-knowledge proofs and smart contracts. Within its ecosystem, the U token is the native gas token and handles three primary roles: paying for gas and fee markets, securing the network through Delegated Proof of Stake (PoS), and enabling cross-chain governance.

The project has a capped supply of 10 billion tokens. It launched a limited mainnet in April 2025 to expand interoperability in the BTCfi space.

What the native network does

Union is built to facilitate trustless interoperability. It has integrated with partners such as Babylon, BOB, Corn, Lombard, Bedrock, and Solv to expand its reach in the BTCfi space. The network has also introduced Auro BTC (auBTC), which is a native cross-chain product designed to generate yield.

The technical foundation includes a record-breaking Groth16 Trusted Setup Ceremony with 5,866 verified contributions. For those who want to inspect the implementation, the project provides its source code on GitHub.

Wallet, transfer, and network-fee checks

Union has contract data for both Ethereum and BNB Smart Chain (BEP20). The verified contract address for U is:

0xba5eD44733953d79717F6269357C77718C8Ba5ed

Before any transfer, you must verify the network and contract address through official sources. You can use the official explorer to check addresses and transactions.

Common mistakes include using lookalike contract addresses or sending tokens to the wrong network. Always confirm which network an exchange is using for withdrawals before initiating a transfer.

Self-custody and withdrawal risks

We have not verified deposit and withdrawal support for the routes listed above unless the source explicitly provides it. You should assume support is not verified until you check the exchange's current status.

Risks to consider:

• Contract verification is required. Always match the contract address against the official website or documentation.
• Exchange availability and KYC requirements vary by country.
• Using the wrong network during a transfer can lead to a permanent loss of funds.

Sources and methodology

The routes listed in this guide come exclusively from verified market-pair rows in our database. We use web research and news for background and risk context. Information from CoinMarketCap pages is treated as low-confidence context and is not used as proof of liquidity, fees, or contract safety. Live market values, such as price and volume, are omitted because they change too frequently to remain accurate in a static guide.
