Step-by-Step Integration Process

1. TokenPay Plugin Installation for EasyPay

TokenPay supports multiple platforms via plugins, including:

• Card-system
  -独角数卡 (Dujiao Digital Card)
  -彩虹易支付 (Rainbow EasyPay)
• V2board

Procedure:

1. Download the epay plugin directory from the TokenPay GitHub repository.
2. Upload all files to your EasyPay installation directory, preserving folder structures (especially /plugins).

2. Database Configuration

Execute these SQL commands via phpMyAdmin:

ALTER TABLE `pay_plugin`
MODIFY COLUMN `types` varchar(4096) CHARACTER SET utf8 COLLATE utf8_general_ci NULL DEFAULT NULL AFTER `link`;

INSERT INTO `pay_type` (`name`, `device`, `showname`, `status`) VALUES 
('TRX', 0, 'TRX', 1),
('USDT_TRC20', 0, 'USDT-TRC20', 1),
('EVM_ETH_ETH', 0, 'ETH', 1),
('EVM_ETH_USDT_ERC20', 0, 'USDT-ERC20', 1),
('EVM_ETH_USDC_ERC20', 0, 'USDC-ERC20', 1),
('EVM_BSC_BNB', 0, 'BNB', 1),
('EVM_BSC_USDT_BEP20', 0, 'USDT-BEP20', 1),
('EVM_BSC_USDC_BEP20', 0, 'USDC-BEP20', 1),
('EVM_Polygon_MATIC', 0, 'MATIC', 1),
('EVM_Polygon_USDT_ERC20', 0, 'USDT-Polygon', 1),
('EVM_Polygon_USDC_ERC20', 0, 'USDC-Polygon', 1);

3. Enabling EVM Chains

Edit EVMChains.json to activate desired payment methods:

{
 "EVMChains": [
 {
 "Enable": true,
 "ChainName": "Ethereum",
 "ChainNameEN": "ETH",
 "BaseCoin": "ETH",
 "ApiKey": "YOUR_ETHERSCAN_API_KEY",
 "ERC20": [
 {
 "Name": "USDT",
 "ContractAddress": "0xdAC17F958D2ee523a2206206994597C13D831ec7"
 },
 {
 "Name": "USDC",
 "ContractAddress": "0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48"
 }
 ]
 },
 {
 "Enable": true,
 "ChainName": "Binance Smart Chain",
 "ChainNameEN": "BSC",
 "BaseCoin": "BNB",
 "ApiKey": "YOUR_BSCSCAN_API_KEY",
 "ERC20": [
 {
 "Name": "USDT",
 "ContractAddress": "0x55d398326f99059ff775485246999027b3197955"
 },
 {
 "Name": "USDC",
 "ContractAddress": "0x8AC76a51cc950d9822D68b83fE1Ad97B32Cd580d"
 }
 ]
 }
 ]
}
