mx-sdk-js-web-wallet-provider

Signing provider for dApps: MultiversX (Web) Wallet.

Documentation is available on docs.multiversx.com, while an integration example can be found here.

Note that we recommend using dapp-core instead of integrating the signing provider on your own.

Distribution

npm

Installation

``
npm install @multiversx/sdk-web-wallet-provider
`

$3

In order to compile the library, run the following:

`
npm install
npm run compile
`

$3

####Login
`
export async function login() {
let provider = createProvider();
await provider.login();
}
`

####Sign Transactions
`
export async function signTransactions() {
let provider = createProvider();

let firstTransaction = {
toPlainObject: function () {
return {
nonce: 42,
value: "1",
receiver: "erd1uv40ahysflse896x4ktnh6ecx43u7cmy9wnxnvcyp7deg299a4sq6vaywa",
gasPrice: 1000000000,
gasLimit: 70000,
data: Buffer.from("hello").toString("base64"),
chainID: "T",
version: 1
};
}
};

let secondTransaction = {
toPlainObject: function () {
return {
nonce: 43,
value: "1",
receiver: "erd1uv40ahysflse896x4ktnh6ecx43u7cmy9wnxnvcyp7deg299a4sq6vaywa",
gasPrice: 1000000000,
gasLimit: 70000,
data: Buffer.from("world").toString("base64"),
chainID: "T",
version: 1
};
}
};

await provider.signTransactions([firstTransaction, secondTransaction]);
}
`


In production, if needed, one can use sdk-core' Transaction.fromPlainObject() to wrap the plain transaction objects returned by the provider.

For example:

`
let plainSignedTransactions = provider.getTransactionsFromWalletUrl();
let transactions = plainSignedTransactions.map(item => Transaction.fromPlainObject(item));
`


#### Show signed messages
`
export async function showSignedTransactions() {
let provider = createProvider();
let plainSignedTransactions = provider.getTransactionsFromWalletUrl();
alert(JSON.stringify(plainSignedTransactions, null, 4));
}
`

#### Logout
`
export async function logout() {
let provider = createProvider();
await provider.logout({ callbackUrl: window.location.href, redirectDelayMilliseconds: 10 });
}
