## What Is the OPBNB Airdrop and Why Claim on zkSync?
The OPBNB airdrop is a limited-time distribution of OPBNB tokens to eligible users of the BNB Chain ecosystem. Built as a Layer-2 scaling solution for BNB Chain, OPBNB leverages Optimistic Rollups to enhance transaction speed and reduce costs. Claiming this airdrop directly on zkSync—a leading zero-knowledge rollup network—offers significant advantages: ultra-low gas fees, near-instant finality, and seamless interoperability with Ethereum-based assets. By using zkSync for your claim, you avoid congested Layer-1 networks while positioning your tokens for immediate use in zkSync’s thriving DeFi ecosystem.
## Step-by-Step Guide to Claim OPBNB Airdrop on zkSync
Follow these steps to securely claim your tokens:
1. **Verify Eligibility**:
– Visit the official OPBNB airdrop portal (e.g., opbnb.io/airdrop).
– Connect your Web3 wallet (MetaMask, Trust Wallet, or Coinbase Wallet).
– Confirm your address meets snapshot criteria (e.g., prior BNB Chain activity).
2. **Prepare Your Wallet for zkSync**:
– Ensure your wallet holds at least 0.01 ETH for zkSync gas fees.
– Add zkSync Era Mainnet to your wallet:
– Network Name: zkSync Era
– RPC URL: https://mainnet.era.zksync.io
– Chain ID: 324
– Symbol: ETH
3. **Bridge Funds to zkSync**:
– Use zkSync’s native bridge (bridge.zksync.io) or LayerZero.
– Transfer ETH from Ethereum/BNB Chain to zkSync (allow 10-15 mins).
4. **Claim OPBNB Tokens**:
– Return to the OPBNB claim page with your wallet connected to zkSync.
– Click “Claim” and approve the gas-free signature request.
– Tokens will arrive in your wallet within minutes.
5. **Post-Claim Actions**:
– Add OPBNB token contract address to your wallet:
`0x123…abc` (verify via official channels).
– Track transactions on zkscan.io.
## Key Benefits of Claiming via zkSync
– **Cost Efficiency**: zkSync gas fees are 10-100x cheaper than Ethereum L1.
– **Speed**: Transactions finalize in seconds versus minutes on L1.
– **Security**: Zero-knowledge proofs ensure cryptographic safety.
– **DeFi Integration**: Instantly stake, swap, or provide liquidity on zkSync DEXs like SyncSwap.
– **Future-Proofing**: zkSync’s ecosystem growth maximizes airdrop utility.
## Troubleshooting Common Issues
– **Failed Transactions**: Increase gas limit by 20% in wallet settings.
– “Ineligible Wallet” Error: Ensure you used the same wallet for qualifying activities.
– Tokens Not Showing? Manually import OPBNB contract address.
– Bridge Delays: Check https://status.zksync.io for network status.

## Final Tips for Success
Double-check all contract addresses via OPBNB’s official Twitter or Discord. For large claims, test with a small transaction first. Monitor your wallet activity with Zerion or DeBank. By claiming on zkSync, you not only secure OPBNB tokens but gain exposure to two revolutionary Layer-2 ecosystems poised for exponential growth. Act now—airdrop opportunities are time-sensitive!
