Урок 2 в Ethereum Wallet

В этом уроке мы распределим акции среди участников DAO.

После выполнения первого урока, все акции находятся у аккаунта, который создавал DAO.

Распределить акции можно двумя способами:

1. напрямую отправить другому пользователю сети токены акций;
2. cоздать контракт Shareholder, обратившись к билдеру Aira BuilderShareholder, который снимет со счёта founder, указанное количество токенов акций при вызове функции sign() адресом, который был указан при создании данного контракта как получателя recipient.

Вариант 1

Нет ничего проще, чем просто отправить акции на другой аккаунт. Для этого нажимаем на аккаунт, держатель акции, нажимаем кнопку Send напротив токена акции:

Указываем кол-во и адрес, еще раз нажимаем кнопку Send

Акции отправлены.

Вариант 2

Иногда возникают ситуации, когда нужно получить подтверждение от агента (аккаунта) о том, что он согласен стать акционером. Для этого можно использовать специальный контракт Shareholder. Чтобы его создать, обратимся в контракт Factory Core, в раздел Get module. Ищем адрес Aira BuilderShareholder.

Адрес есть - 0xA6e9ef2FF0663F0ec47Ec4024500729905943bEf
Теперь создадим контракт. Для этого добавим контракт сборщика Aira BuilderShareholder в список ваших 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":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"},{"constant":false,"inputs":[{"name":"_desc","type":"string"},{"name":"_shares","type":"address"},{"name":"_count","type":"uint256"},{"name":"_recipient","type":"address"},{"name":"_client","type":"address"}],"name":"create","outputs":[{"name":"","type":"address"}],"payable":true,"type":"function"},{"anonymous":false,"inputs":[{"indexed":true,"name":"client","type":"address"},{"indexed":true,"name":"instance","type":"address"}],"name":"Builded","type":"event"}]

Создадим модуль Shareholder. Для этого используем функцию Create в сборщике Aira BuilderShareholder. Указываем адрес акций, кол-во, которое мы хотим отдать и адрес будущего акционера.

Когда транзакция будет подтверждена сетью, найдем адрес созданного контракта в Latest Events сборщика Aira BuilderShareholder.

Теперь нам нужно разрешить созданному контракту Shareholder распоряжаться акциями. Для этого добавим контракт акций Shares, в список наблюдаемых контрактов:

Address − адрес ваших Shares
Abi:

[{"constant":true,"inputs":[],"name":"name","outputs":[{"name":"","type":"string"}],"payable":false,"type":"function"},{"constant":false,"inputs":[{"name":"_spender","type":"address"},{"name":"_value","type":"uint256"}],"name":"approve","outputs":[{"name":"","type":"bool"}],"payable":false,"type":"function"},{"constant":true,"inputs":[],"name":"totalSupply","outputs":[{"name":"","type":"uint256"}],"payable":false,"type":"function"},{"constant":false,"inputs":[{"name":"_from","type":"address"},{"name":"_to","type":"address"},{"name":"_value","type":"uint256"}],"name":"transferFrom","outputs":[{"name":"","type":"bool"}],"payable":false,"type":"function"},{"constant":true,"inputs":[],"name":"decimals","outputs":[{"name":"","type":"uint8"}],"payable":false,"type":"function"},{"constant":false,"inputs":[],"name":"kill","outputs":[],"payable":false,"type":"function"},{"constant":false,"inputs":[{"name":"_value","type":"uint256"}],"name":"burn","outputs":[],"payable":false,"type":"function"},{"constant":false,"inputs":[{"name":"_value","type":"uint256"}],"name":"emission","outputs":[],"payable":false,"type":"function"},{"constant":false,"inputs":[{"name":"_owner","type":"address"}],"name":"delegate","outputs":[],"payable":false,"type":"function"},{"constant":true,"inputs":[{"name":"_owner","type":"address"}],"name":"balanceOf","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":"symbol","outputs":[{"name":"","type":"string"}],"payable":false,"type":"function"},{"constant":false,"inputs":[{"name":"_to","type":"address"},{"name":"_value","type":"uint256"}],"name":"transfer","outputs":[{"name":"","type":"bool"}],"payable":false,"type":"function"},{"constant":true,"inputs":[{"name":"_owner","type":"address"},{"name":"_spender","type":"address"}],"name":"allowance","outputs":[{"name":"","type":"uint256"}],"payable":false,"type":"function"},{"constant":false,"inputs":[{"name":"_spender","type":"address"}],"name":"unapprove","outputs":[],"payable":false,"type":"function"},{"inputs":[{"name":"_name","type":"string"},{"name":"_symbol","type":"string"},{"name":"_decimals","type":"uint8"},{"name":"_start_count","type":"uint256"}],"type":"constructor"},{"anonymous":false,"inputs":[{"indexed":true,"name":"_from","type":"address"},{"indexed":true,"name":"_to","type":"address"},{"indexed":false,"name":"_value","type":"uint256"}],"name":"Transfer","type":"event"},{"anonymous":false,"inputs":[{"indexed":true,"name":"_owner","type":"address"},{"indexed":true,"name":"_spender","type":"address"},{"indexed":false,"name":"_value","type":"uint256"}],"name":"Approval","type":"event"}]

Далее, используем функцию Approve в контракте Shares, указав адрес контракта Shareholder и кол-во акций, которыми он сможет распоряжаться. Также, убедитесь, что аккаунт с которого вы инициируете транзакцию совпадает с адресом, являющемся Owner для контракта Shares.

Добавим контракт Shareholder в список наблюдаемых контрактов:

Abi:

[{"constant":true,"inputs":[{"name":"","type":"address"}],"name":"signer","outputs":[{"name":"","type":"bool"}],"payable":false,"type":"function"},{"constant":false,"inputs":[],"name":"accept","outputs":[],"payable":false,"type":"function"},{"constant":true,"inputs":[],"name":"beneficiary","outputs":[{"name":"","type":"address"}],"payable":false,"type":"function"},{"constant":true,"inputs":[],"name":"value","outputs":[{"name":"","type":"uint256"}],"payable":false,"type":"function"},{"constant":false,"inputs":[],"name":"kill","outputs":[],"payable":false,"type":"function"},{"constant":false,"inputs":[],"name":"close","outputs":[],"payable":false,"type":"function"},{"constant":true,"inputs":[],"name":"closed","outputs":[{"name":"","type":"uint256"}],"payable":false,"type":"function"},{"constant":false,"inputs":[{"name":"_owner","type":"address"}],"name":"delegate","outputs":[],"payable":false,"type":"function"},{"constant":true,"inputs":[],"name":"description","outputs":[{"name":"","type":"string"}],"payable":false,"type":"function"},{"constant":true,"inputs":[],"name":"owner","outputs":[{"name":"","type":"address"}],"payable":false,"type":"function"},{"constant":true,"inputs":[],"name":"hardOffer","outputs":[{"name":"","type":"address"}],"payable":false,"type":"function"},{"constant":true,"inputs":[],"name":"token","outputs":[{"name":"","type":"address"}],"payable":false,"type":"function"},{"inputs":[{"name":"_description","type":"string"},{"name":"_token","type":"address"},{"name":"_value","type":"uint256"},{"name":"_beneficiary","type":"address"}],"type":"constructor"}]

Мы готовы к подписанию контракта акционера − Shareholder. Используем функцию Accept, отправив транзакцию с аккаунта, для которого был создан контракт.

Если вы всё сделали правильно, акции попадут на нужный аккаунт.

Завершение урока

Для того чтобы завершить урок и получить AIR, необходимо
сделать Approve 1 акции на адрес 2-го урока.
Address 2-го урока −
0x7f7EE513F78fe20A94e420FCDFb8164769920194

Далее нужно обратиться к функции Execute второго урока, указав адрес вашего DAO и название токена акций.
Address 2-го урока − 0x7f7EE513F78fe20A94e420FCDFb8164769920194
