这是一个关于 starcoin 区块链上如何定义用户自定义 Coin|Token 的例子。

首先，按照 Run/Join Network 中的描述启动一个开发网络，并获得一些硬币，比如"1000000000"。

在本文档中，我将使用我的开发网络的默认帐户地址"0xb19b07b76f00a8df445368a91c0547cc"来代表发行和发送新Token的人。我还创建了另一个帐户"0x831d51f0087596e6aa4e7b3b9c85f945"并将一些 STC 转移给它。该帐户将用于接收Token。

源文件位于my-token

编译模块

修改模块地址：

编辑Move.toml
MyToken = “0xABCDE” 改为 MyToken = “0xb19b07b76f00a8df445368a91c0547cc” In console, run:

$ mpm release

Packaging Modules:
         0xb19b07b76f00a8df445368a91c0547cc::MyToken
Release done: release/my_token.v0.0.1.blob, package hash: 0xc3b9cf32499f4bdf0a38d57f7c7c66a6f4df69881a8980bcda2106782dce88ba

它将编译模块，您将获得二进制包

导入 0xb19b07b76f00a8df445368a91c0547cc 账号.

starcoin% account import -i 0x05c9d09cd06a49e99efd0308c64bfdfb57409e10bc9e2a57cb4330cd946b4e83 -p my-pass 
{
  "ok": {
    "address": "0xb19b07b76f00a8df445368a91c0547cc",
    "is_default": false,
    "is_readonly": false,
    "public_key": "0x7932502fa3f8c9bc9c9bb994f718b9bd90e58a6cdb145e24769560d3c96254d2",
    "receipt_identifier": "stc1pkxds0dm0qz5d73zndz53cp28esyfj4ue"
  }
}

然后，解锁帐户并部署 MyToken 模块。

获得 devnet 测试币

dev get-coin 0xb19b07b76f00a8df445368a91c0547cc

解锁帐户

starcoin% account unlock 0xb19b07b76f00a8df445368a91c0547cc -p my-pass

starcoin% dev deploy /guide-to-move-package-manager/my-token/release/my_token.v0.0.1.blob -s 0xb19b07b76f00a8df445368a91c0547cc -b

                }
              },
              "raw": "0xc7610000000000000000000000000000"
            }
          }
        },
  .....
  ....
}

执行脚本功能

首先，使用 0xb19b07b76f00a8df445368a91c0547cc 账户初始化模块。

starcoin% account execute-function --function 0xb19b07b76f00a8df445368a91c0547cc::MyToken::init -s 0xb19b07b76f00a8df445368a91c0547cc --blocking

其次，使用 0xb19b07b76f00a8df445368a91c0547cc 账户铸币一些 MyToken。

starcoin% account execute-function --function 0xb19b07b76f00a8df445368a91c0547cc::MyToken::mint --blocking --arg 1000000u128 -s 0xb19b07b76f00a8df445368a91c0547cc

然后，让默认账户接受新的Token。
一个账户只有在已经采用了 Token 的情况下才能接受 Token。

starcoin% account accept_token -s 0x831d51f0087596e6aa4e7b3b9c85f945 0xb19b07b76f00a8df445368a91c0547cc::MyToken::MyToken --blocking

随后， 0xb19b07b76f00a8df445368a91c0547cc账户转账1000个MyToken给默认用户

starcoin%  account execute-function --function 0x1::TransferScripts::peer_to_peer_v2 -t 0xb19b07b76f00a8df445368a91c0547cc::MyToken::MyToken --arg 0x831d51f0087596e6aa4e7b3b9c85f945 --arg 10000u128 -s 0xb19b07b76f00a8df445368a91c0547cc

最后，显示默认用户的余额。

starcoin% account show 0x831d51f0087596e6aa4e7b3b9c85f945
{
  "ok": {
    "account": {
      "address": "0x831d51f0087596e6aa4e7b3b9c85f945",
      "is_default": true,
      "is_readonly": false,
      "public_key": "0x29894dafe73616f807ed48aef1978974122d790a62be767d115f396b422cbb75",
      "receipt_identifier": "stc1psvw4ruqgwktwd2jw0vaeep0eg5eac86k"
    },
    "auth_key": "0xedf8fad3eb73ab981793ca5b29b9f660831d51f0087596e6aa4e7b3b9c85f945",
    "balances": {
      "0x00000000000000000000000000000001::STC::STC": 100000533341,
      "0xb19b07b76f00a8df445368a91c0547cc::MyToken::MyToken": 10000
    },
    "sequence_number": 3
  }
}
