Поддержка дивидендов для всех токенов. :
Например:
- Комиссия за обработку дивидендов
- маркетинговые сборы,
- комиссия за управление ликвидностью,
- Плата за сжигание (черная дыра)
- Вышеупомянутые сборы могут быть установлены по-разному для покупки и продажи.
Параметры развертывания:
Например:name_: (название)
symbol_: (символ)
totalSupply_: (тираж)
rewardAddr_: Контракт токена на дивиденды, BSC обычно используемый адрес токена указан ниже
marketingWalletAddr_: собственный кошелек
serviceAddr_: 0x333336b1f76404693a4bd3885170A0F9a807940F
buyFeeSetting_: [ 4,3,2,1 ] (дел. денд, ликвидность, маркетинг, сжигание)
sellFeeSetting_: [5,4,3,2] (дивиденды, ликвидность, маркетинг, сжигание)
tokenBalanceForReward_: 100000000000000000000000000000 (сколько токенов вы держите для участия в дивидендах. Добавьте после суммы 18 0)
