Урок 7 в Ethereum Wallet

В этом уроке мы создадим модуль Crowdsale, для привлечения инвестиций.

Найдем сборщик Aira BuilderCrowdSale в контракте Factory Core. Как это сделать было рассмотрено в предыдущих уроках.

Далее, добавим сборщик Aira BuilderCrowdSale в реестр наблюдаемых контрактов: Abi:

[{"constant":false,"inputs":[{"name":"_uri","type":"string"}],"name":"setSecurityCheck","outputs":[],"payable":false,"type":"function"},{"constant":false,"inputs":[{"name":"_beneficiary","type":"address"}],"name":"setBeneficiary","outputs":[],"payable":false,"type":"function"},{"constant":true,"inputs":[],"name":"beneficiary","outputs":[{"name":"","type":"address"}],"payable":false,"type":"function"},{"constant":false,"inputs":[],"name":"kill","outputs":[],"payable":false,"type":"function"},{"constant":false,"inputs":[{"name":"_buildingCostWei","type":"uint256"}],"name":"setCost","outputs":[],"payable":false,"type":"function"},{"constant":false,"inputs":[{"name":"_owner","type":"address"}],"name":"delegate","outputs":[],"payable":false,"type":"function"},{"constant":true,"inputs":[],"name":"buildingCostWei","outputs":[{"name":"","type":"uint256"}],"payable":false,"type":"function"},{"constant":true,"inputs":[],"name":"owner","outputs":[{"name":"","type":"address"}],"payable":false,"type":"function"},{"constant":true,"inputs":[],"name":"getLastContract","outputs":[{"name":"","type":"address"}],"payable":false,"type":"function"},{"constant":false,"inputs":[{"name":"_target","type":"address"},{"name":"_credits","type":"address"},{"name":"_sale","type":"address"},{"name":"_start_time_sec","type":"uint256"},{"name":"_duration_sec","type":"uint256"},{"name":"_start_price","type":"uint256"},{"name":"_step","type":"uint256"},{"name":"_period_sec","type":"uint256"},{"name":"_min_value","type":"uint256"},{"name":"_end_value","type":"uint256"},{"name":"_client","type":"address"}],"name":"create","outputs":[{"name":"","type":"address"}],"payable":true,"type":"function"},{"constant":true,"inputs":[{"name":"","type":"address"},{"name":"","type":"uint256"}],"name":"getContractsOf","outputs":[{"name":"","type":"address"}],"payable":false,"type":"function"},{"constant":true,"inputs":[],"name":"securityCheckURI","outputs":[{"name":"","type":"string"}],"payable":false,"type":"function"},{"anonymous":false,"inputs":[{"indexed":true,"name":"client","type":"address"},{"indexed":true,"name":"instance","type":"address"}],"name":"Builded","type":"event"}]

Создадим модуль CrowdSale, используя функцию Create в сборщике Aira BuilderCrowdSale.

При обращении к сборщику необходимо указать:

Target - Адрес получателя финансирования
Credits - Адрес токена для инвестирования
Sale - Адрес токена для продажи
Start time - начало краудсейла в unixtime
Duration - продолжительность краудсейла в секундах
Start Price - начальная цена в минимальных единицах
Step - шаг увеличения цены в процентах
Period - период шага увеличения цены в секундах
Min_value - минимальное кол-во инвестиций для успешного завершения краудсейла
End_value - максимальное кол-во инвестиций для успешного завершения краудсейла

Как видим, модуль Crowdsale имеет различные настройки для гибкости проведения краудсейла. Мы будем использовать его в протейшем виде.

Не забудьте отправить немного Eth сборщику, его работа стоит 0.01 Eth.

Добавим этот модуль в список наблюдаемых контрактов. Адрес найдем в Latest Events контракта Aira BuilderCrowdSale.

Теперь переведем несколько токенов для продажи, контракту Crowdsale. Имейте ввиду то, что цены при создании контракта краудсейла указываются в минимальных единицах.

Далее, необходимо сделать Approve для контракта Crowdsale с аккаунта, который будет участвовать в финансировании, в Ether Leger.

Последнее, что нужно сделать, это вызвать функцию Deal в контракте Crowdsale. Если вы все сделали правильно, то произойдет продажа Credits за ETH.

Завершение урока

Чтобы завершить урок, необходимо обратиться к контракту Lesson 7 для вызова функции Execute, передав адрес контракта Crowdsale. Address Lesson 7 - 0x0A6e7705680AB6145701be0F4D8E6643bBa20AFF
