Hi ?,
multisig.tools is a multi-signature app on Firefly. It allows you to create a payment from a multi-signature account, when other users who are authorized to sign the transaction open the app, the transaction will appear on the page. When the user chooses to sign it, the system will display the required weight and the obtained weight in real time. Once the transaction has gained enough weight, it will be submitted to the horizon network. Users can view the status of the transaction in real time on the transaction details page.
The program is still work in test net, and what I'm going to do is:
1. Rewrite the front end using React
2. Make it run as a separate web app, not only in Firefly (with Firefly for security reason)
3. Support the hardware ledger wallet
4. Better user guidance interface
Firefly offers a good API, and maybe you should try it. :-)
