@metahubwallet/wallet-plugin-metahub

A Session Kit wallet plugin for the Metahub wallet extension. Built directly on @metahubwallet/sdk without the Scatter protocol layer.

Usage

import {SessionKit} from '@wharfkit/session'
import {WalletPluginMetahub} from '@metahubwallet/wallet-plugin-metahub'

const kit = new SessionKit({
    // ... other options
    walletPlugins: [new WalletPluginMetahub()],
})

This plugin will only work in a browser environment where the Metahub extension is installed.

How it works

• login calls MetahubClient.login({appName, chainId}) and returns the account whose chainId matches the selected chain, as a PermissionLevel.
• sign hands the resolved transaction to the extension as plain JSON (Antelope types serialize Bytes fields to hex via toJSON, so no ABI lookup is needed on this side).
• The extension may transform the transaction before signing — e.g. Metahub's smooth mode prepends a metahubpower::noop action for CPU cosigning. When the returned serializedTransaction differs from what was submitted, the plugin rebuilds a ResolvedSigningRequest from the wallet's bytes (and reuses the wallet's decoded transaction for resolvedTransaction) and returns it as response.resolved, so Session Kit broadcasts the transformed tx that the signatures actually cover.
