-------------------------------------------------------------------------------- /README.md: -------------------------------------------------------------------------------- 1 | # SaintArnould (Tokyo) Token and CrowdSale Contracts 2 | 3 | ## Getting started 4 | ICO(イニシャルコインオファリング)はEtheruem上のスマートコントラクトで自動生成されます。 5 | 6 | 1. 発行上限はなし。 1 ETH = 5000 SAT 7 | 2. セール期間は `fundingStartBlock` から `fundingEndBlock`まで 8 | 3. 発行者はセール終了後販売量の10%を追加で発行し6ヶ月間ロックする。 9 | 10 | ご質問は [@syrohei](https://twitter.com/syrohei)　もしくは syrohei@gmail.com　まで。 11 | 12 | 仕様環境 13 | - Truffle v3.2.5 14 | - EthereumJS TestRPC v3.0.3 15 | - Node.js v6.9.2 16 | 17 | ``` 18 | npm install 19 | truffle migrate 20 | ``` 21 | 22 | ## Contract Audit 23 | 24 | このコントラクトは現在監査中です。もしバグが見つかった場合には速やかにTwitterを通し監査報告をすることとします。 25 | 26 | 2017/7/3 17:00 - Contract Test and Deployment process test has been verified.　 27 | 28 | 2017/7/3 17:04 - コントラクトのバグ調査を開始、約72時間後に監査が完了しmasterブランチにマージされる予定です。 29 | 30 | 2017/7/4 14:20 - **バグバウンティプログラムを開始、最大20ETHまでを上限にコードの監査結果を募集します。** 31 | 32 | 2017/7/7 21:00 - **スマートコントラクトはレビュー状態を終了しパブリックライブに移行しました。** 33 | 34 | ## Fnctions 35 | ``` 36 | function transfer(address _to, uint256 _value) public returns (bool) { } 37 | ``` 38 | セールで購入されたアドレスはこのfunctionをコールしてトークンを送信します。 39 | 40 | ``` 41 | function buy(address _sender) internal { } 42 | ``` 43 | 購入function。トリガーはコントラクトに着金した時 44 | 45 | ``` 46 | function finalize() external { } 47 | ``` 48 | セール終了後のコントラクト制御を制限します。また、トークン送金が可能になります。 49 | ``` 50 | function transferFounders(address _to, uint256 _value) public returns (bool) { } 51 | ``` 52 | 53 | ファウンダーのトークンはロックされており、あるblocktimeに到達しない限り送信されることはありません。 54 | ファウンダーは通常の`transfer()`を使うことができないことに注意してください。 55 | 56 | ## Test 57 | 58 | To run the tests, run a TestRPC locally with testrpc -b 1 and run this code. 59 | 60 | ``` 61 | truffle test 62 | ``` 63 | 64 | 65 | ## LICENSE 66 | 67 | MIT 68 | --------------------------------------------------------------------------------
