, but it can be renamed with the Referral argument name setting. 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 to overcome the etherscan.io and openexchangerates.org API rate limits. We use the cache to limit the API calling rate to a reasonable value
The PRO version is required for this feature. Free 7 days Trial is available.
Test if caching is enabled. It is important to overcome API rate limits in production.
Refresh your site page twice and check the HTML source produced for LOG:
records.
For non-PRO plugin version and for PRO version with Cache plugin not configured properly they would looks like this:
LOG: etherscan.io rate_data API is called
LOG: etherscan.io rate_data API call result is stored
LOG: openexchangerates.org API is called
LOG: openexchangerates.org API call result is saved
LOG: etherscan.io total_received API is called
LOG: etherscan.io total_received API call result is stored
Note: make sure to enable the
Object Cache
in theW3 Total Cache
if you use it.
For PRO plugin version with Cache
properly configured you should see no LOG:
records most of the time.
See the ICO Launch: WordPress Cache Plugin guide to configure the caching plugin.
ICO Fiat Money
The Ethereum ICO WordPress Plugin can be configured to display fiat currency like USD instead of the default ETH, BNB or MATIC. In this mode user still pay with Ether using MetaMask, but all sums are displayed in the currency chosen for user convenience.
The PRO version is required for this feature. Free 7 days Trial is available.
Note that this is useful only if you have implemented something like the oraclize.it
interface in your Crowdsale smart contract. Also, make sure to configure the openexchangerates.org App Id setting if non-USD fiat currency is used here.
You can use the Crowdsale Contract and ERC20 Token Development Service to let us do this job for you.
First of all, look for the Base currency and Base symbol settings. By default they are configured for Ether, but you always can configure it for any other currency, including fiat currencies, e.g. USD
.
Make sure to adjust values of these fields, since they are currency dependent:
- Increase/Decrease step,
- Min allowed value,
- Max allowed value,
- The ICO token rate,
- ICO soft cap,
- ICO hard cap,
- Private sale seed.
It also makes sense to replace USD with ETH in the List of coins setting.
As a result:
- The token sell widget accepts sum in USD and displays the currency used,
- The Progressbar widget displays the current sum, soft and hard caps with the used currency symbol,
- The Amount field in the Purchases table widget is shown in USD with a used currency symbol too
See the ICO Fiat Money for a detailed configuration guide please.
FREE Features
