node.js script for retrieving, modifying, and updating Frame wallets. Meant to be run it its own folder. Kill Frame first.

frameWallets.js

// probably a smart idea to make sure that Frame isn't running when this is executed
const fs = require('fs');
// this location assumes Mac installation
let frameConfigLocation = `${process.env.HOME}/Library/Application Support/frame/config.json`;
// testMode will create a copy of the frame Config in the local folder and modify that instead of the original
const testMode = true;
let frameConfig;
let frameConfigAccounts;
const exampleAddressObj = {
    id: '0x223c067F8CF28ae173EE5CafEa60cA44C335fecB',
    name: 'Urbit Awesomeness',
    lastSignerType: 'trezor',
    address: '0x223c067F8CF28ae173EE5CafEa60cA44C335fecB',

    signer: '',
    requests: {},
    ensName: 'URBIT.ETH',
    tokens: {},
    created: '13283371:1632340314349'
}

const enableTestMode = async () => {
    try {
        await fs.copyFileSync(frameConfigLocation, "./frameConfigBackup.json");
        console.log(`file at ${frameConfigLocation} has been backed up`);
        frameConfigLocation = './frameConfigBackup.json';
    } catch (err) {
        console.log('error copying file:',err);
    }
}

const readFromDisk = async () => {
    try {
        // read file from disk
        frameConfig = await JSON.parse(fs.readFileSync(frameConfigLocation, 'utf8'));
        // extract the accounts. I'm assuming 14 could be the version? could be something that changes
        frameConfigAccounts = frameConfig.main.__[14].main.accounts
    } catch (err) {
        console.log(err);
    }
}

const writeToDisk = async () => {
    try {
        await fs.writeFileSync(frameConfigLocation, JSON.stringify(frameConfig, null, 2));
    } catch (err) {
        console.log('error writing file:', err);
    }
}

const readModifyWrite = async () => {
    if (testMode) {
        await enableTestMode();
    };
    await readFromDisk();

readModifyWrite();

Similar script but for zapper.fi wallets - https://gist.github.com/Beasta/6b0649125cd138ab7c7c11764689111e
