Keeper Wallet is a browser extension that enables secure interaction with Waves-enabled web services.
Seed phrases and private keys are encrypted and stored within the extension and cannot be accessed by online dApps and services, making sure that users' funds are always protected from hackers and malicious websites. Completion of a transaction doesn't require entering any sensitive information.
Keeper Wallet is designed for convenience, so users can sign transactions with just one click. 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.
On browser pages that operate under http/https
(not local pages with file://
protocol) with Keeper Wallet extension installed, KeeperWallet
global object becomes available.
In KeeperWallet
you will find the following methods:
All methods except for on
operate asynchronously and return Promises.
In code, you can use TypeScript types.
In Keeper Wallet, 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 the website to access Keeper Wallet. 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 the error message {message: "Api rejected by user", code: 12}
will be displayed in response to all requests. The user won't see new notifications. To grant access, the user has to mark the website as trusted in the interface.
If a website is trusted, Keeper Wallet public data are returned.
Example:
KeeperWallet.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 KeeperWallet.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();

Supports events:
update
– subscribe for updates of the state.Example:
KeeperWallet.on('update', state => {
//state object as from KeeperWallet.publicState
});
If a website is not trusted, events won't be displayed.
This is a method for obtaining a signature of authorization data while verifying Waves' user. If the the signature is valid, be sure that the given blockchain account belongs to that user.
Example:
const authData = { data: 'Auth on my site' };
KeeperWallet.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 KeeperWallet.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 referrer
or 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/waves_logo.svg',
referrer: 'https://waves.exchange/',
successPath: 'login',
};
KeeperWallet.auth(authData)
.then(data => {
//data – data from Keeper Wallet
//verifying signature and saving the address...
console.log(data);
})
.catch(error => {
//processing the error
});
If the verification is successful, Keeper Wallet returns to the Promise
an object containing data for signature verification:
host
– host that requested a signature.name
– name of an application that requested a signature.prefix
– prefix participating in the signature.address
– address in Waves network.publicKey
– user's public key.signature
– user's signature.version
– API version.Possible 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 was previously blocked by the user.A method for signing transactions in Waves network. See the description of supported transaction types in Transactions section below.
Example:
const txData = {
type: 4,
data: {
amount: {
assetId: 'WAVES',
tokens: '1.567',
},
fee: {
assetId: 'WAVES',
tokens: '0.001',
},
recipient: 'test',
},
};
KeeperWallet.signTransaction(txData)
.then(data => {
//data – a line ready for sending to Waves 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.
In the example, we are signing a transaction for transferring WAVES to the alias test
in Waves network.
Response:
{
"version": 2,
"assetId": "",
"amount": 156700000,
"feeAssetId": "",
"fee": 100000,
"recipient": "recipient",
"attachment": "",
"timestamp": 1548770230589,
"senderPublicKey": "public key",
"proofs": ["signature"],
"type": 4
}
Possible errors:
{message: "User denied message", code: 10}
– the user denied the request.{ message: "Api rejected by user", code: 12 }
— the website was previously blocked by the user.{message: "Invalid data", data: "Reason", code: 9}
– invalid/incomplete request data.This is similar to signTransaction
, but it also broadcasts a transaction to the blockchain. See the description of supported transaction types in Transactions section below.
Example:
const txData = {
type: 4,
data: {
amount: {
assetId: 'WAVES',
tokens: '1.567',
},
fee: {
assetId: 'WAVES',
tokens: '0.001',
},
recipient: 'test',
},
};
KeeperWallet.signAndPublishTransaction(txData)
.then(data => {
//data - a line ready for sending to Waves network's node (server)
})
.catch(error => {
//processing errors
});
Response: a reply from Waves network returns as a line containing the entire past transaction.
Possible errors:
signTransaction
.{message: "Failed request", data: "Error description", code: 15}
– a request was signed but not broadcasted.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. See the description of supported transaction types in Transactions section below.
Example:
const name = 'For Test';
const tx = [
{
type: 4,
data: {
amount: {
assetId: 'WAVES',
tokens: '1.567',
},
fee: {
assetId: 'WAVES',
tokens: '0.001',
},
recipient: 'test',
},
},
{
type: 4,
data: {
amount: {
assetId: 'WAVES',
tokens: '0.51',
},
fee: {
assetId: 'WAVES',
tokens: '0.001',
},
recipient: 'merry',
},
},
];
KeeperWallet.signTransactionPackage(tx, name);
Sign two transaction:
test
.merry
.Response: a unit of two lines – transactions that are signed and ready to broadcast.
Possible errors:
Same as in signTransaction
.
Every user of Waves network has a state (balances, assets, data, scripts), and every past transaction changes this data. More about transactions
In Keeper Wallet API transaction format is different from Node REST API. signTransaction
, signAndPublishTransaction
, and signTransactionPackage
accept transactions as follows:
{
type: number, //transaction type
data: {
... //transaction data
}
}
Keeper Wallet supports the following types of transactions:
Legend keys:
KeeperWallet
.MoneyLike could look as:
{ tokens: 1, assetId: "WAVES" }
{ coins: 100000000, assetId: "WAVES" }
;In both messages, the same price of 1 WAVES 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
.

Keeper Wallet's method for signing an order to the matcher (exchange service). As input, it accepts an object similar to a transaction like this:
{
data: {
...data
}
}
See order details in the Waves protocol documentation.
See how to calculate the order fee in Waves.Exchange documentation.
Fields:
*version
: 1,2,3.amount
: MoneyLike – amount.price
: MoneyLike – price.orderType
: 'sell'/'buy' – order type.matcherFee
: MoneyLike – order fee.matcherPublicKey
: string – public key of the matcher in base58.expiration
: string/number – the order's expiration time in ms.*timestamp
: string/number – current time in ms.*senderPublicKey
: string – user's public key in base58.Example:
KeeperWallet.signOrder({
data: {
matcherPublicKey: '9cpfKN9suPNvfeUNphzxXMjcnn974eme8ZhWUjaktzU5',
orderType: 'sell',
expiration: Date.now() + 100000,
amount: {
tokens: '100',
assetId: 'WAVES',
},
price: {
tokens: '0.01',
assetId: '8LQW8f7P5d5PZM7GtZEBgaqRPGSzS3DfPuiXrURJ4AJS',
},
matcherFee: {
tokens: '0.1',
assetId: 'WAVES',
},
},
});
then(tx => {
console.log("Hurray! I've signed an order!!!");
}).catch(error => {
console.error('Something went wrong', error);
});
Response: a line with data for sending to the matcher.
Possible errors:
{ message: "User denied message", code: 10 }
– the user rejected the request.{ message: "Api rejected by user", code: 12 }
— the website was previously blocked by the user.{ message: "Invalid data", data: "Reason", code: 9 }
– invalid/incomplete request data.Keeper Wallet's method for creating an order to the matcher is identical to signOrder
, but it also tries to send data to the matcher.
Response: the matcher's reply line about successful creation of an order.
Possible errors:
signOrder
.{message: "Failed request", data: "Error description", code: 15}
– a request has been signed, but not sent to the matcher.Keeper Wallet's method for signing cancellation of an order to the matcher. As input, it accepts an object similar to a transaction like this:
{
data: {
...data
}
}
Fields:
id
: string – order ID in base58.*senderPublicKey
: string – user's public key in base58.Example:
KeeperWallet.signCancelOrder({
data: {
id: '31EeVpTAronk95TjCHdyaveDukde4nDr9BfFpvhZ3Sap',
},
});
Response: a data line for sending to the matcher.
Possible errors:
{ message: "User denied message", code: 10 }
– the user rejected the request.{ message: "Api rejected by user", code: 12 }
— the website was previously blocked by the user.{ message: "Invalid data", data: "Reason", code: 9 }
– invalid/incomplete request data.Keeper Wallet's method for cancelling an order to the matcher. It works identically to signCancelOrder
, but also tries to send data to the matcher. You should specify two more fields: priceAsset
and amountAsset
from the order.
Example:
KeeperWallet.signAndPublishCancelOrder({
priceAsset: 'WAVES',
amountAsset: '8LQW8f7P5d5PZM7GtZEBgaqRPGSzS3DfPuiXrURJ4AJS',
data: {
id: '31EeVpTAronk95TjCHdyaveDukde4nDr9BfFpvhZ3Sap',
},
})
.then(() => {
console.log("Hurray! I've cancelled the order");
})
.catch(error => {
console.error('Something went wrong', error);
});
Response: data returned by the matcher.
Possible errors:
signCancelOrder
.{message: "Failed request", data: "Error description", code: 15}
– a request has been signed, but not sent to the matcher.Keeper Wallet'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 only signing data for a request to the matcher for your orders.
Fields:
timestamp
: number/string – time in ms.*senderPublicKey
: string – user's public key in base58.Example:
KeeperWallet.signRequest({
data: {
timestamp: 234234242423423,
},
});
Response: a line with a signature in base58.
Possible errors:
{ message: "User denied message", code: 10 }
– the user rejected the request.{ message: "Api rejected by user", code: 12 }
— the website was previously blocked by the user.{ message: "Invalid data", data: "Reason", code: 9 }
– invalid/incomplete request data.Keeper Wallet's method for signing a custom data for different services. It accepts an object:
version
: 1binary
: 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-transactions library.
Example:
KeeperWallet.signCustomData({
version: 1,
binary: 'base64:AADDEE==',
});
Response:
{
version: 1,
binary: 'base64:AADDEE==',
signature: '...',
publicKey: '...'
}
Possible errors:
{ message: "User denied message", code: 10 }
– the user rejected the request.{ message: "Api rejected by user", code: 12 }
— the website was previously blocked by the user.{ message: "Invalid data", data: "Reason", code: 9 }
– invalid/incomplete request data.version
: 2data
: array of objects:
type
: "binary"/string/"integer"/"boolean" – field type.key
: string – field name.value
: string(base64)/string/number/booleanBytes to sign: [255, 255, 255, 2, ...(from data array to bin)]. For the details check serializeCustomData method in waves-transactions library.
Example:
KeeperWallet.signCustomData({
version: 2,
data: [{ type: 'string', key: 'name', value: 'Mr. First' }],
});
Response:
{
version: 2,
data: [{ type: 'string', key: 'name', value: 'Mr. First' }]
signature: '...',
publicKey: '...'
}
Possible errors:
{ message: "User denied message", code: 10 }
– the user rejected the request.{ message: "Api rejected by user", code: 12 }
— the website was previously blocked by the user.{ message: "Invalid data", data: "Reason", code: 9 }
– invalid/incomplete request data.Validate custom data:
{
version: 1,
binary: 'base64:AADDEE==',
signature: '...',
publicKey: '...'
}
or
{
version: 2,
data: [{ type: 'string', key: 'name', value: 'Mr. First' }],
signature: '...',
publicKey: '...'
}
Example:
KeeperWallet.verifyCustomData({
version: 1,
binary: 'base64:AADDEE==',
publicKey: '3BvAsKuGZe2LbSwKr9SA7eSXcNDKnRqN1j2K2bZaTn5X',
signature:
'2bLJYR68pwWrUUoatGbySz2vfY76VtzR8TScg1tt5f9DVDsFDCdecWrUiR4x6gFBnwF4Y51uszpouAwtSrg7EcGg',
}).then(result => {
console.log(result);
});
Response: true/false.
Possible errors:
{ message: "User denied message", code: 10 }
– the user rejected the request.{ message: "Api rejected by user", code: 12 }
— the website was previously blocked by the user.Check whether the user allowed your website to access Keeper Wallet.
Example:
KeeperWallet.resourceIsApproved().then(result => {
console.log(result);
});
Response: true/false.
Check whether the user blocked your website in Keeper Wallet.
