Copay

Copay is an open-source multisig wallet. Each peer is has control of her private keys, that never leave their system. Copay has two components: a client and a p2p network of servers. The servers form a p2p global network that exchange messages between clients and provide Bitcoin blockchain API services using insight-API.

Copay-client is implemented in JS client-side. It can work as a:

web app,
a webview based mobile app,
or a node-kit based desktop app.

Remove TxProposals

Download a wallet backup in all peers
close the wallet
delete browser's localStorage (this will delete ALL YOUR WALLETs, be sure to have backups for ALL)
go to Import Wallet
Add the param: ?skip=txProposals to the URL (e.g: https:/copay.io//#!/import?skip=txProposals) (other possible params are: privateKey, publicKeyRing, separeted with ,)
A banner in the page should appear: https://www.evernote.com/shard/s49/sh/ee2282a5-b712-42c7-ae2b-196d5d94c345/6c72c7e59af341d76884dfe0ce08d43a

This procedure is for reseting a Copay Wallet status, reseting its transactions proposals, addresses and peer metainfo. It should be used as a last resource to recover wallet's funds, in case there is an error on the wallet or a corrupted backup.

A. Gathering the information

You need to have access of the ALL peers of the wallet (*)
If you will run the procedure on the same computer, BE SURE not to use the same browser, since localStorage is shared. You can use: 1 Chrome window, and 1 Chrome incognito window, 1 Firefox window, 1 Firefox incognito window.
Start by creating backups of all the peers.
Go to 'More' in the peers wallet, and add the &advanced=1 at the end of the URL. This should show some advanced options
Take note of the Master Private Key of ALL the peers.

Test only one class at time. Use sinon.stub (.returns & .yields) to create on the fly mockups for dependencies.
Test the API Only. Never access class internals for checking / setting values. Use the API, this prevents to brake test in the future. E.g.:

  class.setName('name');
  class.name.should.equal('name'); // Wrong
  clase.getName().should.equal('name'); //Right

The following is a procedure to grab the extended priv key, for copayers that are

Open the wallet in Chrome
Open the javascript console
Inspect an element on the html (could be any element), inspect by using the magnifing glass.

After selecting an item, go back to the javascript console and type:

 var w= angular.element($0).scope().wallet; w?'OK':'';

	var opts = {
	blockchain: new Blockchain(...),,
	storage: localstorage / insight / drive,
	networking: new Async(...),
	};

	Identity.create(email, password, opts, function(err, iden){
	//
	})
