How to Get a Free Airdrop from Union: Step-by-Step Guide

The Union project has officially launched its airdrop, and now is the perfect time to get involved. You can earn real rewards by spending just 25 minutes of your time. Participation is completely free, and the project has already raised $16 million from top-tier funds.

🔍 What is Union?

Union is a zk-bridge connecting Ethereum and Cosmos, enabling IBC (Inter-Blockchain Communication) to work within the Ethereum ecosystem. It provides:

Seamless cross-chain communication
High security and scalability
zk-based infrastructure for fast, trustless bridging

The project is live on testnet, and users are being rewarded for their onchain activity — now’s your chance to earn airdrop eligibility.

🛠 Step-by-Step Guide to Join the Union Airdrop

Step 1: Connect Your Wallets

Go to the Union Transfer App:
👉 https://app.union.build
Connect your EVM-compatible wallet (like MetaMask).
Connect your Cosmos wallet (Keplr or Leap Wallet).

Step 2: Get Test Tokens

Open the Faucet tab.
Request test tokens from the available faucet providers.
👉 Repeat this step for every listed faucet to maximize your balances.

Step 3: Wrap ETH on Sepolia Testnet

Visit the contract on Etherscan:
👉 https://sepolia.etherscan.io/address/0xae78736Cd615f374D3085123A210448E74Fc6393#writeContract
Click "Write Contract" and connect your MetaMask.
Use the deposit function, enter the amount, and confirm the transaction.

Step 4: Use the Bridge

Go back to https://app.union.build
Choose a bridge route (e.g., Sepolia → Osmosis).
Select a token and complete the test transaction.
Try multiple directions and tokens — more onchain activity increases your airdrop eligibility.

🚀 Why Should You Join?

Union is not just another bridge — it’s a next-gen zk-based infrastructure combining the power of Ethereum and Cosmos through IBC.
