Hello Orbit Chain Community

Orbit Chain team is the first bridge protocol to support Ethereum PoW, EthereumFair network. ETHW/ETF airdrop will proceed solely for Orbit ecosystem participants.

With the successful Ethereum PoS Merge, all existing Ethereum assets support the Ethereum PoS network. The hard-forked Ethereum PoW, EthereumFair network is operating normally. However, the trading is limited since ERC-20 assets such as USDT, DAI, and ORC do not have significant value due to gaps with Ethereum PoS assets. ETH in Ethereum PoW and EthereumFair networks will airdrop ETHW as planned.

Orbit Chain team will change oTokenW airdrop distribution plan to EthereumFair’s ETF for more practical airdrops. Ethereum PoW, EthereumFair network support schedule and hosted airdrop with detailed policy will be as follows.

■ The First Bridge protocol supporting Ethereum PoW, EthereumFair

Orbit Bridge will support Ethereum PoW, EthereumFair network from September 30, 2022 (UTC).

■ ETHW, ETF Airdrop

1. Schedule

2. Holders

Polygon Block #33126399

4. Token Contract Address

oETHW : 0x5a36597fb14c8f28ea3c3163754f8149ef1d45a8
oETF : 0xCD8FfBB3725A1b3234DBeb024F7172a75435E638

5. Distribution Process

The AirDrop token can be received via the ‘Airdrop Distribution Contract’ as allocated.

(1) Personal Wallet Address(EOA), oETH deposited on lending/yield farming of KLAYswap/Meshswap

Directly distributed by Orbit Bridge team

(2) Upgradable Contract

Claim function of ‘Airdrop Distribution Contract’ makes the Deployer send the allocated quantity on the contract to the recipient.

    function claimable(address target) external view returns (uint256);
	function claim(address recipient) external;
}

(3) Non-Upgradable Contract

claimByExecutor function of ‘Airdrop Distribution Contract’ makes the Deployer send the allocated quantity on the contract to the recipient after verification of Non-Upgradable Contract by official support team of Orbit Chain(support@orbitchain.io)
