TODO: get the finished frontend code from https://github.com/makevoid/xdai-wallet

Bitcoin Lightning Network wallet

First iteration for a crypto wallet, coin backend, bitcoin (of course :D), lightning network version (LN is a layer 2 protocol for fast instant transfer).

Currently in alpha status, exploring:

• html5 generation via haml (this branch) / pug (possible option)
• html5 customelements (preferred option)
• svelte or riot.js (nice options, learn svelte or reuse riot.js boilerplate - extract from: https://github.com/appliedblockchain/appii_ui-old/tree/master/comp)

It should be easy (now that I have a LN [lnd] node fully synced and working to test the BTC version), but I would like to reuse the UI to do another payment oriented wallet which may come first than the bitcoin LN one.

Coin backends

It would be nice to have one wallet for each of this options, I should complete #1 and #3 thou before starting all 6+ (I haven't listed doge but it's too :much-wow: to not attempt it :D).

• 1 ) BTC - Lightning (L2) - STARTED - UI code taken from https://github.com/xdai-wallet (cordova, android+browser) - https://github.com/bitcoin-keychain (which uses https://github.com/makevoid/eth-keychain)
• 2 ) BTC

<--- Development is at this stage (n3)

• 3 ) ETH - XDAI (L3..) (sort of "lightning", but if the authorities fail, or if dai fails, that's bad, byebye *coins)
• 4 ) ETH - DAI (L3.)
• 5 ) BCH (L3)
• 6 ) ETH (L3)
• 7 ) Doge (L3)

Wallet Feature Baseline

show mnemonic, no screenshot, use 12 words, verify 40% of the words

no email, no bullshit

LN

LN GRPC full node backend at the moment, even if there are 3 options:

• 1. grpc for full node (main option, desirable atm.)
• 2. fully hosted using pk under https to auth
• 3. hybrid (neutrino? will have to investigate)

<3itcoin

xDai ETH backed, this is nice as it's a stablecoin, but of course

also it's a mobile wallet, you shouldn't have a lot of coins in a mobile wallet to begin with (unless it's a secured, always off, no-simcard, wifi-shielded airgapped android phone you put in a safe or something..., a laptop with a minimal linux distro and a wifi hardware switch for a airgapped full node is a better solution usually than current gen mobiles)

$$

Wallet "business model":

• App to pay people for when other payments don't work (easiest example, to split a bill)
• This is to drive bitcoin adoption
• In case of xDai or BCH or other wallets, always offer an in app popup to download the Bitcoin / Bitcoin LN version and point to a crypto to crypto exchange to exchange the lesser secure coins to BTC (the exchange should not force KYC, so no shapeshift unfortunately anymore :/)

User (demo) "flow"

• User A and B meet in person, they have both an android phone with the app installed
• User A - Wants to receive a payment from user B (let's say they went to a restaurant where User B paid, and User A wants to "split the bill" with B)
• User A - Opens the wallet app, goes to the Receive screen, taps the QR code which gets magnified, and optionally specifies an amount and a label (The QR code shows the LN invoice or a normal BTC/*coin address / *URL)
• User B - Opens his/hers wallet app, scans the receiving QR code of User B and confirms a payment

...some seconds later...

• User A and B - Check transaction list, the transaction is shown with all the details, user taps [view in explorer] selects a block explorer and sees the transaction

Wish me luck for the build,

hope to get something into some real users hands soon!
