Automatically cosign transactions to assume resource costs using a noop action.


yarn install @wharfkit/transact-plugin-cosigner


Include this transactPlugin in your Wharf Session Kit instance and specify the relevant information.

const session = new Session({
    chain: {
        id: '73e4385a2708e6d7048834fbc1079f2fabb17b3c125b146af438971e90716c4d',
        url: 'https://jungle4.greymass.com',
    permissionLevel: 'wharfkit1111@test',
    transactPlugins: [
        new TransactPluginCosigner({
            actor: 'wharfkitnoop',
            permission: 'cosign',
            privateKey: '5JfFWg1CWsNTeXTWMyfChXXbyD31TCTknSVGwXDSpT6bPxKYLMM',
            // Optional parameters
            // contract: 'greymassnoop', // The noop contract name
            // action: 'noop', // The noop contract action
    walletPlugin: wallet,

Any transaction initiated with this session will automatically prepend a greymassnoop:noop action and sign it using the permissions specified for the TransactPluginCosigner.
