Polkadot

Polkadot extension

This project provides some utility classes enabling the use of the Polkadot JS extension or other compatible extensions (e.g. SubWallet) with the Logion client.

Usage​

Start signing content using the extension.

import { getAccounts, ExtensionSigner } from '@logion/extension';
import { ValidAccountId } from "@logion/node-api";

const signer = new ExtensionSigner();
const injectedAccounts = await getAccounts(
    "Your app name",
    [ "polkadot-js", "subwallet-js" ], // A list of extensions
);
const addresses = injectedAccounts.map(account => ValidAccountId.polkadot(account.address));
const authenticated = await client.authenticate(addresses, signer);

// Pass `signer` as an argument when needed
info

If several accounts are available in the listed extensions, the call to authenticate will require a signature for each one of them.
