區塊鏈技術EOS開發系列之如何開發合約發行代幣

我們以currency合約為例：

釋出合約：

➜  programs git:(master) ✗ ./eosc/eosc contract

Positionals:

account TEXT                The account to publish a contract for

wast-file TEXT              The file containing the contract WAST

abi-file TEXT              The ABI for the contract

Options:

-h,--help                  Print this help message and exit

-a,--abi TEXT              The ABI for the contract

➜  programs git:(master) ✗ ./eosc/eosc contract  currency ../../contracts/currency/currency.wast ../../contracts/currency/currency.abi

更多命令：

➜  programs git:(master) ✗ ./eosc/eosc

ERROR: RequiredError: Subcommand required

Command Line Interface to Eos Daemon
