The PRO version is required for this feature to work. Free 7 days Trial is available.

Note: The Transaction data to send to your crowdsale contract setting will be replaced by the referral address if specified in an URL.

You can use this solidity code snippets as a base for your referral/affiliate system implementation.

Put this code to your payable token buy function:

if(msg.data.length == 20) {
  address referer = bytesToAddress(bytes(msg.data));
  // self-referrer check
  require(referer != address(0x0), "zero-referrer");
  require(referer != msg.sender, "self-referrer");
  // 2% affiliation reward
  uint refererTokens = tokens.mul(2).div(100);
  // bonus for referrer
  token.transfer(referer, refererTokens);
}

The bytesToAddress function:

function bytesToAddress(bytes source) internal pure returns(address) {
  uint result;
  uint mul = 1;
  for(uint i; i < 20; i++) {
      result = result.add(mul.mul(uint8(source[19-i])));
      mul = mul.mul(256);
  }
  return address(result);
}

You can use the Crowdsale Contract and ERC20 Token Development Service to let us do this job for you.

Airdrop

Airdrop is a free tokens distribution to promote your project.

This plugin can be used to implement a user initiated airdrop. It means that user can request some amount of your tokens for free. Good for you, the user will be responsible for the airdrop transaction gas fees.

To configure this plugin for airdrop, just set the minimum allowed setting to zero and the Crowdsale address to your airdrop contract. Note that your airdrop contract should be able to accept zero payments and send some tokens in return.

The Transaction data setting can be used to call some specific function of your Airdrop contract.

The Online ABI Encoding Service and Ethereum Signature Database can be useful when calculating the right value for the Transaction data setting.

For example, the simple buy() function will have this signature: 0xa6f2ae3a.

Bounty

Time based bounty schedule can be used.

The ICO start date and Bounty settings are used to configure this functionality.

The JSON array of your bounty values can be specified in the Bounty setting.

Example:

[[7, 40], [7, 30], [7, 20], [7, 10], [7, 5]]

The 7 number is for days count for the corresponding bounty period. Bounty periods are calculated from the ICO start date setting.

The 40, 30, 20, 10, 5 are percents of additional tokens to be sent to buyer for free.

Your Crowdsale contract should be able to work with it. You can use the Crowdsale Contract and ERC20 Token Development Service to let us do this job for you.

Transaction data

The Transaction data setting to send to your crowdsale contract is supported

The PRO version is required for this feature. Free 7 days Trial is available.

It is an advanced feature. It can be required if your Crowdsale contract can not just accept Ether by send, but need some payable method to be called. Do not use if unsure.

The Online ABI Encoding Service and Ethereum Signature Database can be useful when calculating the right value for the Transaction data setting.

For example, the simple buy() function will have this signature: 0xa6f2ae3a.

Cache

You can use any of the [persistent cache WP plugins](https://codex.wordpress.org/Class_Reference/WP_Object_Cache#Persistent_Cache_Plugins …
