Turtle Shell v1.0.7

Turtle Shell is a Google Chrome extension that allows users to securely interact with TurtleNetwork-enabled web services from the within the browser.

Seed phrases and private keys are encrypted and stored within the extension and cannot be accessed by online dApps and services, making sure that user's funds are always protected from hackers and malicious websites. Completion of a transaction doesn't require entering any sensitive information.

Turtle Shell is designed for convenience, so users can sign transactions with just a couple of clicks. Users can create multiple wallets and switch between them easily. And if a user ever forgets the password to the account, it can be recovered from the seed phrase.

Turtle Shell API

On browser pages that operate under the http/https (not worked local pages with file:// protocol) with Turtle Shell extension installed, TurtleShell global object becomes available, featuring the following methods:

• auth
• publicState
• signAndPublishCancelOrder
• signAndPublishOrder
• signAndPublishTransaction
• signCancelOrder
• signOrder
• signTransaction
• signRequest
• signTransactionPackage
• signCustomData
• verifyCustomData
• notification
• encryptMessage
• decryptMessage
• resourceIsApproved
• resourceIsBlocked
• on

All methods, except for "on" operate asynchronously and return promises.

In code you can use TypeScript types

On initialize window.TurtleShell has not api methods. You can use TurtleShell.initialPromise for waiting end initializing api.

Example:

    TurtleShell.initialPromise
        .then((keeperApi) => {
            /*...init app*/
            keeperApi.publicState().then( state => startApp(state));
        })

In Turtle Shell, for greater security and ease of use, each new website using API has to be allowed by the user. At the first attempt to use API (except "on"), the user will see a request to allow that website's access to Turtle Shell. If the user agrees to allow access, the website is considered trusted and can use API on its pages. Otherwise, the website is blocked, and an error message will be displayed in response to all requests {message: "Api rejected by user", code: 12}. The users won't see new notifications. To grant access, the user will mark the website as trusted in the interface.

Description of methods

publicState

If a website is trusted, Turtle Shell public data is returned.

Example:

    TurtleShell.publicState()
        .then(state => {
            console.log(state); //displaying the result in the console
            /*...processing data */
        }).catch(error => {
            console.error(error); // displaying the result in the console
            /*...processing errors */
        })

or

    const getPublicState = async () => {
        try {
            const state = await TurtleShell.publicState();
            console.log(state); // displaying the result in the console
            /*... processing data*/
        } catch(error) {
            console.error(error); // displaying the result in the console
            /*... processing errors */
        }
      }


      const result = await getPublicState();

REPLY

    "account": {
        "name": "foo",
        "publicKey": "bar",
        "address": "turtle address",
        "networkCode": "network byte",
        "balance": {
            "available": "balance in tn",
            "leasedOut": "leased balance"
        }
    },
    "network": {
        "code": "L",
        "server": "https://privatenode2.blackturtle.eu/",
        "matcher": "https://privatematcher.blackturtle.eu/"
    },
    "messages": [],
    "txVersion": {
        "3": [ 2 ],
        "4": [ 2 ],
        "5": [ 2 ],
        ...
    }
}

Description of query return fields

• initialized - boolean keeper initialized
• locked - boolean keeper in wait mode
• account – current account, if the user allowed access to the website, or null
• network – current Waves network, node and matcher addresses
• messages – signature request statuses
• txVersion – available transaction versions for each type

Possible errors

• initialized - boolean shell initialized
• locked - boolean shell in wait mode
• account – current account, if the user allowed access to the website, or null
• network – current TN network, node and matcher addresses
• messages – signature request statuses
• txVersion – available transaction versions for each type

notification

Send message to keeper. Ypu can send message only 1 time in 30 sec for trusted sites with send permission.

notification facilitates input of the following data

• { message: "Init Turtle Shell and add account" } – Turtle Shell is not initialized
• { message: "Add Turtle Shell account" } – Turtle Shell accessed, but there are no accounts
• { message: "User denied message" } – the user denied the website operation with Turtle Shell

return Promise

Example:

Allows subscribing to Turtle Shell events.

       TurtleShell.notification({
            title: 'Hello!',
            message: 'Congratulation!!!'
       });

Possible errors

• {message: "Incorrect notification data", data: "title has more than 20 characters", code: "19"} - Incorrect notification title
• {message: "Incorrect notification data", data: null, code: "19"} - Incorrect notification data
• {message: "Can't sent notification", data: {msg: "Min notification interval 30s. Wait 28.017s."}, code: "18"} - try send later, you can send 1 message in 30 sec
• {message: "Api rejected by user", code: 12} the user denied the request or the website is not trusted.

encryptMessage

You can encrypt string messages to account in Waves network. You need have recipient publicKey.

TurtleShell.encryptMessage(*string to encrypt*, *public key in base58 string*, *prefix is secret app string need for encoding*)

Example:

       TurtleShell.encryptMessage('My message', '416z9d8DQDy5MPTqDhvReRBaPb19gEyVRWvHcewpP6Nc', 'my app')
       .then((encryptedMessage) => {
            console.log(encryptedMessage);
       });

Possible errors

• { message: "Init Waves Keeper and add account" } – Waves Keeper is not initialized
• { message: "App is locked" } – Waves Keeper is locked
• { message: "Add Waves Keeper account" } – Waves Keeper accessed, but there are no accounts
• { message: "User denied message" } – the user denied the website operation with Waves Keeper

decryptMessage You can decrypt string messages from account in Waves network to you. You need have sender publicKey and encrypted message.

TurtleShell.decryptMessage(*string to decrypt*, *public key in base58 string*, *prefix is secret app string need for encoding*)

Example:

       TurtleShell.decryptMessage('**encrypted msg**', '416z9d8DQDy5MPTqDhvReRBaPb19gEyVRWvHcewpP6Nc', 'my app')
       .then((message) => {
            console.log(message);
       });

TurtleShell.on("update", state => { //state object as from TurtleShell.publicState });

If a website is not trusted, events won't show.

**auth**

This is a method for obtaining a signature of authorization data while verifying TurtleNetwork's user. It works the same way as [Waves Auth API](https://docs.wavesplatform.com/en/development-and-api/client-api/auth-api.html).

Example:

```js
    const authData = { data: "Auth on my site" };
    TurtleShell.auth(authData)
        .then(auth => {
            console.log(auth); //displaying the result on the console
            /*...processing data */
        }).catch(error => {
            console.error(error); // displaying the result on the console
            /*...processing errors */
        })

or

    const getAuthData = async authData => {
        try {
            const state = await TurtleShell.auth(authData);
            console.log(state); // displaying the result on the console
            /*... processing data */
        } catch(error) {
            console.error(error); // displaying the result on the console
            /*... processing errors */
        }
    }


    const authData = { data: "Auth on my site" };
    getAuthData(authData);

auth facilitates input of the following data

• name – name of the service (optional field)
• data – a string line with any data (required field)
• referrer – a websites' full URL for redirect (optional field)
• icon – path to the logo relative to the referreror origin of the website (optional field)
• successPath – relative path to the website's Auth API (optional field)

Example

    const authData = {
        data: "Generated string from server",
        name: "My test App",
        icon: "/img/icons/tn_logo.svg",
        referrer: "https://client.turtlenetwork.eu/",
        successPath: "login"
    };


    TurtleShell.auth(authData).then((data) => {
        //data – data from Turtle Shell
        //verifying signature and saving the address...
        console.log(data);
    }).catch((error) => {
        //processing the error
    });

If the verification is successful, Turtle Shell will return in the promise an object containing data for signature verification:

• host – a host that requested a signature
• name – the name of an application that requested a signature
• prefix – a prefix participating in the signature
• address – an address in Turtle network
• publicKey – the user's public key
• signature - signature
• version – API version

How to verify a signature?

ERRORS

• {message: "Invalid data", data: "[{"field":"data","type":"string","message":"field is required"}]", code: 9} – signature data contain errors
• {message: "User denied message", code: 10} – the user denied the request
• {message: "Api rejected by user", code: 12} - the website is not trusted

signTransaction

A method for signing transactions in TN's network.

Example:

    const txData = {
        type: 4,
        data: {
            amount: {
               assetId: "TN",
               tokens: "1.567"
            },
            fee: {
                assetId: "TN",
                tokens: "0.001"
            },
            recipient: "test"
        }
    };
    TurtleShell.signTransaction(txData).then((data) => {
        //data – a line ready for sending to TN network's node (server)
    }).catch((error) => {
        //Processing errors
    });

API returns lines, not an object, as in javascript precision is lost in operation with 8-byte integers.

A description of supported transaction types is below.

In the example, we are signing a transaction for transferring TN to the alias test in TN's network.

REPLY {"version":2,"assetId":"", "amount":156700000,"feeAssetId":"",fee:100000, "recipient":"recipient","attachment":"", "timestamp":1548770230589,"senderPublicKey":"public key","proofs":["signature"],"type":4}

ERRORS

• {message: "User denied message", code: 10} – The user denied the request.
• {message: "Api rejected by user", code: 12} – The website is not trusted.
• {message: "Invalid data", data: "Reason", code: 9} – invalid/incomplete request data.

signAndPublishTransaction

This is similar to "signTransaction", but it also broadcasts a transaction to the blockchain.

Example:

   const txData = {
           type: 4,
           data: {
               amount: {
                  assetId: "TN",
                  tokens: "1.567"
               },
               fee: {
                   assetId: "TN",
                   tokens: "0.001"
               },
               recipient: "test"
           }
       };
       TurtleShell.signAndPublishTransaction(txData).then((data) => {
           //data - a line ready for sending to TN network's node (server)
       }).catch((error) => {
           //processing errors
       });

REPLY A reply from TN network returns as a line containing the entire past transaction.

ERRORS

• Same as signTransaction
• {message: "Filed request", data: "Error description", code: 15} – a request was signed but not broadcasted

signTransactionPackage

A package transaction signature. Sometimes several transactions need to be simultaneously signed, and for users' convenience, up to seven transactions at ones could be signed. Only certain types of transactions are permitted:

• 3 – token issue
• 4 – token transfer
• 5 – token re-issue
• 6 – token burning
• 10 – creating an alias for an address in TN's network
• 11 – mass transfer
• 12 - DataTransaction

Example:

    const name = "For Test";
    const tx = [{
        type: 4,
        data: {
            amount: {
               assetId: "TN",
               tokens: "1.567"
            },
            fee: {
                assetId: "TN",
                tokens: "0.001"
            },
            recipient: "test"
    }},{
        type: 4,
        data: {
            amount: {
               assetId: "TN",
               tokens: "0.51"
            },
            fee: {
                assetId: "TN",
                tokens: "0.001"
            },
            recipient: "merry"
        }
    }];


    TurtleShell.signTransactionPackage(tx, name)

Sign two transaction:

• Transfer 1.567 TN to the alias test
• Transfer 0.1 TN to the alias merry

REPLY

A unit of two lines – transactions that are signed and ready to be broadcasted.

ERRORS Same as in "signTransaction"

Transactions

Every user of TN's network has a state (balances, assets, data, scripts), and every past transactions changes these data.
In Turtle Shell API it is different from NODE REST API.

signTransaction, signAndPublishTransaction accept transactions as follows

{
    type: number //transaction type,
    data: {
        ... //transaction data
    }
}

Legend keys

• • optional field, data are automatically supplied from TurtleShell.
    [x,y] – length limit from x to y.
    [,x] – length limit to x.
    [y,] – length limit from y.
    [x-y] – number from x to y. x/y - x or y. (JLM) - JAVA LONG MAX = 9 223 372 036 854 775 807
    MoneyLike - price

MoneyLike could look as:

• { tokens: 1, assetId: "TN" }
• { coins: 100000000, assetId: "TN" };

In both messages, the same price of 1 TN is indicated. You can easily convert coins into tokens and back, if you know in what asset the price is indicated and you have received its precision tokens = coins / (10 ** precision)
If the field contains other types than MoneyLike, for instance, string/MoneyLike , the sum is indicated as a number in  coins.

      }).catch((error) => {
           console.error("Something went wrong", error);
      });

In case of a success, we are re-issuing a new asset in the quantity of 1,000,000, and your balance will show 10,000.00 Best Token

             ],
             fee: {
                 "tokens": "0.002",
                 "assetId": "TN"
             }
        }
   }).then((tx) => {
        console.log("Hurray! I've sent hi to my friends!!!");
   }).catch((error) => {
        console.error("Something went wrong", error);
   });

In case of a success, 0.002 TN will be sent to alias1 and alias2.

Тype 12 DATA TRANSACTION - saving data

             ],
             fee: {
                 "tokens": "0.01",
                 "assetId": "TN"
             }
        }
   }).then((tx) => {
        console.log("Hurray! I've saved data!!!");
   }).catch((error) => {
        console.error("Something went wrong", error);
   });

In case of a success, new data will be stored in the state.

Тype 13 SET SCRIPT – scrypting an account

• script string - script
• *fee MoneyLike -fee
• *senderPublicKey string - sender's public key in base58
• *timestamp number/string – time in ms

For cancelling a script the field scripthas to be "". Script development on RIDE

Example:

   TurtleShell.signAndPublishTransaction({
        type: 13,
        data: {
             script: "",
             fee: {
                 "tokens": "0.04",
                 "assetId": "TN"
             }
        }
   }).then((tx) => {
        console.log("Hurray! I've cancelled a script!!!");
   }).catch((error) => {
        console.error("Something went wrong", error);
   });

In case of a success, the script will be removed from the account.

Example 2:

   TurtleShell.signAndPublishTransaction({
        type: 13,
        data: {
             script: "base64:AQa3b8tHAQa3b8tHAQa3b8tHAQa3b8tHAQa3b8tHAQa3b8tHAQa3b8tHAQa3b8tHAQa3b8tHAQa3b8tHAQa3b8tH",

   }).then((tx) => {
        console.log("Hurray! I've added a script!!!");
   }).catch((error) => {
        console.error("Something went wrong", error);
   });

In case of a success, a new script will be added to the account, allowing any transactions without a signature (be careful!).

             assetId: "",
             script: "base64:AQa3b8tH",
             fee: {
                 "tokens": "0.01",
                 "assetId": "TN"
             }
        }
   }).then((tx) => {
        console.log("Hurray! I have reset a script to the asset!!!");
   }).catch((error) => {
        console.error("Something went wrong", error);

             }
        }
   }).then((tx) => {
        console.log("Hurray! I've signed an order!!!");
   }).catch((error) => {
        console.error("Something went wrong", error);
   });

REPLY: A line with data for sending to the matcher.

ERRORS:

• { message: "User denied message", code: 10 } – the user rejected the request
• { message: "Api rejected by user", code: 12 } – The website is not trusted
• { message: "Invalid data", data: "Reason", code: 9 } - invalid/incomplete request data

signAndPublishOrder

Turtle Shell's method for creating an order to the matcher is identical to signOrder, but it also tries to send data to the matcher.

REPLY: the matcher's reply line about successful creation of an order.

ERRORS:

• Same as for signOrder
• {message: "Filed request", data: "Error description", code: 15} – a request has been signed, but not sent to the matcher

signCancelOrder

Turtle Shell's method for signing cancellation of an order to the matcher. As input, it accepts an object similar to a transaction like this:

    {
        type: 1003,
        data: {
            ...data
        }
    }

• id string – order ID
• *senderPublicKey - string - sender's public key in base58

Example:

    TurtleShell.signCancelOrder({

        }
    });

REPLY: A data line for sending to the matcher.

ERRORS:

• { message: "User denied message", code: 10 } – the user rejected the request
• { message: "Api rejected by user", code: 12 } – The website is not trusted
• { message: "Invalid data", data: "Reason", code: 9 } - invalid/incomplete request data

signAndPublishCancelOrder

Turtle Shell's method for cancelling an order to the matcher. It works identically to signCancelOrder, but also tries to send data to the matcher.

Example:

    TurtleShell.signAndPublishCancelOrder({
        type: 1003,
        priceAsset: '8LQW8f7P5d5PZM7GtZEBgaqRPGSzS3DfPuiXrURJ4AJS',
        amountAsset: 'WAVES',
        data: {
            id: '31EeVpTAronk95TjCHdyaveDukde4nDr9BfFpvhZ3Sap'
        }
    }).then(() => {
        console.log("Hurray! I've cancelled an order");
    }).catch((error) => {
        console.error("Something went wrong", error);
    });

REPLY: Data that came from the matcher

ERRORS:

• Same as for signCancelOrder
• {message: "Filed request", data: "Error description", code: 15} – a request has been signed, but not sent to the matcher

signRequest

Turtle Shell's method for signing typified data, for signing requests on various services. As input, it accepts an object similar to a transaction like this:

    {
        type: number,
        data: {
            ...data
        }
    }

Currently, the method supports the following types:

1001 – signing data for a request to the matcher for your orders

• timestamp number/string
• *senderPublicKey string public key in base58

Example:

    TurtleShell.signRequest({
        type: 1001,
        data: {
            timestamp: 234234242423423
        }
    });

REPLY: a line with a signature in base58.

ERRORS:

• { message: "User denied message", code: 10 } – the user rejected the request
• { message: "Api rejected by user", code: 12 } – The website is not trusted
• { message: "Invalid data", data: "Reason", code: 9 } - invalid/incomplete request data

1004 – signing data for a request to Coinomat

• timestamp number/string

Request:

    TurtleShell.signRequest({
        type: 1004,
        data: {
            timestamp: 234234242423423
        }
    });

REPLY: a line with a signature in base58.

ERRORS:

• { message: "User denied message", code: 10 } – the user rejected the request

• { message: "Invalid data", data: "Reason", code: 9 } - invalid/incomplete request data

signCustomData

Method Waves Keeper for sign custom data for different services, it accepts an object:

version 1

• version 1
• binary string 'base64:....'

Note: This method adds the [255, 255, 255, 1] prefix to the signed bytes. This was done to make it impossible to sign transaction data in this method, which can lead to unauthenticated transactions and phishing. For the details check serializeCustomData method in waves-transaction library.

Example:

    TurtleShell.signCustomData({
         version: 1,
         binary: 'base64:AADDEE=='
    });

REPLY:

   {
        version: 1,
        binary: 'base64:AADDEE==',
        signature: '...',
        publicKey: '...'
   }

ERRORS:

• { message: "User denied message", code: 10 } – the user rejected the request
• { message: "Api rejected by user", code: 12 } – The website is not trusted
• { message: "Invalid data", data: "Reason", code: 9 } - invalid/incomplete request data

version 2

• version 2
• data Array of
  • type "binary"/string/"integer"/"boolean" - field type,
  • key string - field name
  • value /string/string/number/boolean

Bytes to sign: [255, 255, 255, 2, ...(from data Array to bin)] waves-transaction library

Example:

    TurtleShell.signCustomData({
         version: 2,
         data: [{ type: 'string', key: 'name', value: 'Mr. First' }]
    });

REPLY:

   {
        version: 2,
        data: [{ type: 'string', key: 'name', value: 'Mr. First' }]
        signature: '...',
        publicKey: '...'
   }

ERRORS:

• { message: "User denied message", code: 10 } – the user rejected the request
• { message: "Api rejected by user", code: 12 } – The website is not trusted
• { message: "Invalid data", data: "Reason", code: 9 } - invalid/incomplete request data

verifyCustomData

Validate custom data:

       {
           version: 1,
           binary: 'base64:AADDEE==',
           signature: '...',
