Receive Referral Reward

Trader can claim their referral reward via ReferralRewarder contract for each chain.

Contract address

BNB chain: 0xCEaBce51c59d44C8dE3E58599c296787A9523Fc7

Arbitrum One: 0x2100Ed94172b0627D6fe772EB11B16d9Ba1C4CeA

Note: Please use the contract on the exact chain you set to claim reward before

Step 1: Get claimable reward

• Get the reward information via this method

function epoches() external view 
    returns (
        bytes32 merkleRoot,
        bytes32 ipfsHash,
        uint256 totalRewards,
        uint256 totalClaimed,
        uint64 startVestingTime,
        uint64 endVestingTime
    );

The ipfsHash is decoded IPFS CID of the airdrop detail file. You will need to encode to get the original CID, like this

const hex = '1220' + ipfs.slice(2); // remove '0x' prefix and prepend 1220 tag for v2 CID
bs58.encode(Buffer.from(hash, 'hex'))

Eg:

bs58.encode(Buffer.from('1220f6e849cffef302146a84e8d4e41c072410ea214dba9cc05a44af0f302c713a1b', 'hex'));

// result: QmexUSUxsUvDzfns9GUoMw19Gqoj885v6H85XMxu68EpVG

Then use any IPFS gateway to get file content, like this. It is a JSON file with some data. Find your address in the file, something like this

    "address": "0xd93497c4659276569f49a32a7abd0691f5ac4467",

    ]
}

Save the value of the fields id and proof to claim your reward

Step 2: Claim reward

Use this method from the ReferralRewarder contract to claim your reward.

function claimRewards(uint256 _epoch, address _to, uint256 _index, uint256 _rewards, bytes32[] memory _merkleProof);

• _epoch: The epoch number

• _to: The address to which reward will be sent

• _index: the id value in step 1

• _merkleProof: the proof value in step 1

Now the reward should be sent to the address you set.
