Usage

To install the component, do yarn add @polkadot/extension-dapp Here is a brief walk through how to use the different utilities from @polkadot/extension-dapp.

import {

web3Accounts,

web3Enable,

web3FromAddress,

web3ListRpcProviders,

web3UseRpcProvider

} from '@polkadot/extension-dapp';

// returns an array of all the injected sources

// (this needs to be called first, before other requests)

const allInjected = await web3Enable('my cool dapp');

// returns an array of { address, meta: { name, source } }

// meta.source contains the name of the extension that provides this account

const allAccounts = await web3Accounts();

// the address we use to use for signing, as injected

const SENDER = '5DTestUPts3kjeXSTMyerHihn1uwMfLj8vU8sqF7qYrFabHE';

// finds an injector for an address

const injector = await web3FromAddress(SENDER);

// sign and send our transaction - notice here that the address of the account

// (as retrieved injected) is passed through as the param to the `signAndSend`,

// the API then calls the extension to present to the user and get it signed.

// Once complete, the api sends the tx + signature via the normal process

api.tx.balances

.transfer('5C5555yEXUcmEJ5kkcCMvdZjUo7NGJiQJMS7vZXEeoMhj3VQ', 123456)

.signAndSend(SENDER, { signer: injector.signer }, (status) => { ... });
