When you click the pie wedge, it animates, to move out to emphasize that you clicked the wedge. This does nothing useful. I suggest that a easing effect to expand the time series chart of the token would be a better UI feature. velocity.js provides this. see example https://codepen.io/julianshapiro/pen/kBuEi

Following error on Windows, both stabel release and developer branch:

npm ERR! enoent This is most likely not a problem with npm itself
npm ERR! enoent and is related to npm not being able to find a file.

An order may be marked complete before web3 returns updated balances. If the endpoint returned a txhash it could poll web3 for those transactions, waiting to mark orders as "complete" until the transaction is seen.

Some people like to keep their tokens on multiple addresses.

It would be nice to think of a few ways to simplify this for people.

Option 1:

• let people upload more than 1 wallet file, or connect to more than 1 hardware wallet address
  Option 2:
• Faast wallet file format which contains an HD Key, based off of https://www.npmjs.com/package/@faast/ethereum-payments

Is it possible to add support for a new Asset 'on the fly' via the Token Symbol, Contract Address, and decimals such as what's used on MetaMask or MyEtherWallet? Thanks and great project!

for a portfolio comprised of 25% ethereum, and a mixture of alt-coins. Any re-balancing transaction will fail with "Not enough ETH for tx fee". Tested with Trezor.

Due to the re-rendering after a portfolio balance update.

When attempting to navigate to faa.st/app I am redirected to faa.st/app/maker/login and toastr shows "Error fetch your market maker data. Please try again later."

As opposed to having to load the entire chart, show a smaller chart similar to the ones on https://coinmarketcap.com/

Offset the sudden drop in the portfolio balance during a swap by keeping track of the funds that were sent. Include the pending amount in the fiat balance calculation until the swap is complete.

Viewing other tokens and their charts would be very beneficial. Being able to "follow" tokens would require setting a state somewhere. Local storage is used for settings but is not persisted across browsers/devices. Blockstack storage can be a solution but there's a current issue with mixed content (https->http). Server side storage would be another alternative

similar service to ethplorer.io but much nicer view as Faa.st portfolio view is awesome.

e.g: https://ethplorer.io/address/0x2561fd0f1651a6828bafbd41847957fe9b0e0370

I would prefer linear (horizontal) stacked chart, instead of piechart. Pie charts are evil.

The good alternative is presented in the first link. https://cdn-images-1.medium.com/max/800/1*5Vpiq7uzNZEzSEWAP0lzew.jpeg

Ultimately due to rounding errors. I've got a function to fix these, but it's currently only hooked up to the Modify page. Needs to be adjusted since it only tackles numbers over 100.

A failed call to /app/assets will stop the app from loading and display a very brief message. Provide better error messages and retry calls to server in certain situations.

Lets say, I select reasonable but low (for the current time) transaction fee, but the transaction is only confirmed hours or days later (i.e. because network suddenly have more transactions). What will happen with the sent "funds"? Is there a way to get it back, or perform a swap at different rate (if market conditions changed grately), or what? I think the swap and status must show this much more clearly. And possibly automatically include "return" address, in case something goes wrong, to return back coins (minus additional fees for a new transaction and some minor penalty for a trouble), or warn about fees, or something.

New currencies can be added by implementing the Wallet interface.

I can't use the portfolio at faa.st, I get the error Invalid JSON RPC response: {} also tried sending a message to [email protected] but haven't received any response, although this issue is not exclusively related to the source code in repository, there is still a change that it is so I' posting it here nonetheless.

By actively fetching the swap fee while the assets are being "modified", the app can determine whether the amounts will be enough to proceed before clicking "save".

Will require a new api endpoint

The current asset picker was designed for the original swap app but does fulfill all the needs of the portfolio. Users should be able to see more information/charts on the tokens they wish to swap to.

Need to clear intervals/timeouts that continue to poll the order state after closing the wallet.

After signing off on the token purchase, the pending allocation should be visible in the portfolio as "pending transfers". While this requires some sort of state management, html5 allows local storage of such information. https://www.w3schools.com/html/html5_webstorage.asp

While this would not be visible cross platforms, it should smooth out the customer confusion about completed transactions awaiting token transfers. The funds are not gone, the order is just being filled...

Currently the only way to view all transactions is through a block explorer, i.e. https://etherscan.io/. A more "swap" specific view can be presented which combines the send and receive transactions for swaps as well as other transactions. Or simply swaps only to start, using the /orders endpoint
