Mobile App development

Hi, This I my project description CRYPTOCURRENCY (ETHEREUM) WALLET DEVELOPMENT Project To develop a mobile (android/iOS) ETHEREUM wallet. Must work in an android / iOS mobile devices (mobile operating systems, like iOS 8, that exist on hardware-encrypted devices with a 'secure element' security chip, such as iPhone). Features required: Primary requirement Open source Use of latest technology by the developer Simplest User Interface (UI) with great User Experience (UX) Spend tokens without waiting for a confirmation Touch ID support Tons of easy to use functionality Transaction tagging One touch 2FA (3FA would be better) web wallet model 6 digit pin SPV validation Customer control their private key Quick to check recent transaction status To check transactions <6 confirmations without unlocking User experience feedback form -SPV -deterministic -a phrase as backup Donation address Upgradable iOS friendly System backup Restoring it from backup System must safely protect Bitcoin private keys System notification for new transactions Import and export your private key which under the BIP38 rule QR code generator Most important – highest security features. Immune to the following: Man-in-the-middle (MITM) attack Phishing attack Android malware / iOS malware attacks No compromised network in the security architecture Customer must be able to set various security options e.g. set a spending limit PIN, PIN to re-login, etc. Bitcoin plugin for filemaker pro? Choice of colors and fonts and numerous buttons - should be simple 'clean simplicity' and 'zen feeling' By the people, for the people, of the people The customer must be able to: a. back up your wallet b. export your seed files c. able to restore seed cross platform Please refer: Mobile wallet overview: [login to view URL] Personally like the following cryptocurrency wallets: Bread wallet Mycelium Coinbase - for especially its vault features. Perhaps, take bread wallet as the base to develop additional features. Things to avoid Absolutely No bug Cross platform / cross browser / upgradation issues. Points to consider: What happen if the mobile is lost or stolen? Actually with bread wallets requirement on a pin and it's wiping of the wallets after 5 (or 8 or whatever) misentered pins, which takes almost 24 hours to do is actually pretty good protection against a lost phone. My philosophy is that mobile wallets should be like pocket cash. For this, Mycelium wins for me. Bread wallet enforces too much security which makes it cumbersome for me personally. For instance, they require you have a pin lock on your phone. This is a non-starter for me, because I prefer to keep my phone unlocked. They require you write your backup seed first before using which I can't argue with, but I like Mycelium's approach more because when I want to demonstrate cryptocurrency to a new user, writing the seed down first kills the demo. Open source HD wallet - BIP32 or better?? Complete control of your own coins (impossible for Airbitz to access them). Feels like online banking software, so log in on one or more devices with a password and/or pin, spend/receive or add transaction data on one device and the other devices will auto sync, etc. Lose you phone you simply download the app and log in on your new phone/other device to retrieve your coins. Add data (e.g. transaction type, payee, notes, etc) to all transactions. That transaction data is encrypted (impossible for Airbitz to access). Built in directory of local bitcoin accepting establishments, ATMs, etc. How much time it will take to send funds from android vs iOS? Lesser it better for both.
