Fido Wallet(s)

👋 Hola dear community and council! I'm Daniel, long time ecosystem builder, senior "king" ambassador and founder of the Virto Network, the future hub of sustainable d-commerce and services for Polkadot.

Earlier this year with your support my team and I built libwallet, an ultra-light and portable framework for creating fast, secure wallets of all kinds(web apps, extensions, mobile, desktop, hardware, hosted, etc.). It has been an on-going effort of continuous redesign and iteration to get to a point where we are now comfortable with its current architecture to start building real-world and user facing products that accommodate the many interesting use cases of our interconnected ecosystem.

It's our mission to reeally bring blockchain to the masses, for more than two years we've been creating solid foundations* and have being learning first hand from regular citizens what might take for people to use blockchain technology without realizing it and how not to compromise decentralization in the process.

*_Previous work: Web3 grant for orml-payments, Kusama funded Sube, Kreivo common good parachain for Kusama, Bloque insta-stores, decentralized on&off ramps._

Problem

Although a lot of progress has been made all over the place to ease the entry barrier to the Web3, we are still miles away from reaching mass adoption, it's inspiring to see the many efforts the community put in educating new users in the ways of blockchains and decentralization but there's still a long, possibly never ending journey ahead.

It's great to see how the blockchain industry has one of the highest levels of innovation and technology advancement ever seen, the field moves at incredible speeds that are hard even for seasoned technologists to catch up, trying to reeducate the world in "the new better ways" is a common approach in Web3 however it might not be the best option, we could be neglecting the big majority of the population that won't try to follow the latest and greatest, instead we need to be inclusive and find ways to translate the new revolutionary ideas to a common language that results familiar to the people.

Solution

We want help newcomers to easily navigate the world of Web3, wallets are the first interaction point of a user but we are starting simple and a bit different, with a set of constraints that I'll call now the mom rule, any term or action that would require me to explain my mom what it is should be avoided, terms like(at least initially) blockchain, private key, hash, staking, NFTs, browser extension, or even wallet don't pass the mom rule so they are not making it in the first cut since they need explanation.

No metaverse-enabled-NFT-capable killer wallet this time, instead let us introduce you what we hope will become your reliable partner in the quest of exploring the sometimes scary Web3.

Fido 🐶 Your trustworthy Web3 companion

Fido is more than a wallet, it's a development platform. On top of libwallet and a plugin runtime we've prototyped before we are building an ecosystem of wallets for different use cases that can be extended with a variety of services(skills and tricks) developed by the community in their language of preference(JS and WASM). Our target audience being non crypto-native users(including developers) means our product has to feel familiar(e.g. easy login, familiar technologies) yet decentralized.
The Fido project breaks down mainly in two pieces,

• Fido bot: Your companion as hosted wallet that can be interacted with via chat using Matrix, the decentralized communications protocol(bridges to other chats can come later) or other protocols like a traditional HTTP API that gives developers access the different skills your Fido has learned. There will be multiple ways to install Fido so it can stay alert 24/7 and give you a hand whenever you need, depending on the platform it will use the most appropriate libwallet vault backend to keep secrets secure, an interesting one being a vault based on Matrix's SSSS that we have prototyped, it allows backing up your wallet securely in your Matrix account to reduce the risk of losing access.

  • Self-hosted provided as a binary, docker image, or per-configured OS image that can be burned directly to a linux computer as small as a RaspberryPi Zero.
  • Embedded Hardware: Mini-Fido provided as firmware for popular microchips. Initial support for ESP32(-C3) and (future bonus based on what I have available) nrf52840/nrf9160 or the super tiny SAM L11 that could become more of a complementary chewing toy/key-holder/jewellery for Fido that can be powered with just an NFC field.
  • In browser(not yet in scope) backed by a combination of service/shared workers(cool web technology) that allows Fido running fully decentralized in your browser without having to install anything. We would also provide an embeddable iframe/web-component that allows third-party applications access the many skills of your Fido. For Virto Marketplaces it will be an important feature that allows executing payments or approve certain transactions.
  • Matrix app service(not in scope) For communities(like Virto's local communities and marketplaces) with their own Matrix server, this allows non-technical users to have an exclusive companion created for them automatically as soon as they join.
  • Desktop shell(not in scope) Embedded in the desktop application.👇

• Fido Shell: A decentralized super-app for the Web(not an extension), desktop, mobile and terminal. It's the graphical interface and Matrix client used to manage your Fido(s), where you can teach it new skills or tricks(mini appplets) and aggregate the many compatible applications created by the community.
  NOTE: Initiall functionality will be very basic, we will only provide an "accounts skill" with a simple applet for minimal token transfers support and a very simple chat.

  • Web: Hosted in fido.sh and in decentralized form.
  • Desktop: As single executable file that works(should) in most platforms(I'll personally only test on Linux but other team members and community will for extended support).
  • Mobile(not in scope): Very similar deployment as the desktop application for IOS and Android.

⚠️ To set expectations right, this first delivery of the Fido bot and the Fido shell should be consider experimental software not suitable to for managing large amounts of money that could be lost due to bugs in any of the components of our system. After launch we hope to gather enough feedback from the early adopters in the community before we recommend Fido for production use.

🤔 Hard-core crypto fans might initially find the wallet boring as we are focused more on the real-world use cases of Virto that need to pass the mom rule, like buying a t-shirt, ordering food, calling a taxi, etc.

Development and Milestones

We will divide the work in 3 stages that will last a total of 4-5 months, after previous experiences developing small pieces of software at a time that are hard to visualize as part of a bigger whole, this time we aim for a longer runway as it has proven difficult to attract/keep talent when working conditions are short term driven and uncertain.

Stage 1 - Design and architecture

Estimated duration: 1 month

| Task                                         | role  | hours |

Stage 3 - Integrations and deployments

Estimated duration: 1 month

| Task                                         | role  | hours |
|----------------------------------------------|-------|-------|

| *Developer applet for debugging              | f-dev |  1w   |
| Shell and Bot packages(image,docker,bin,...) | f-dev |  1w   |
| Testing and QA                               | lead  |  1w   |
| Infrastructure set-up and server deployments | lead  |  1w   |

* Bonus with low priority

Estimated total hours = 31w * 30h/w = 930h
Total USD cost with avg. hourly rate = 930h * USD$75/h = USD$69_750
Total DOT cost = USD$69_750 / 7.394 USD/DOT(EMA30) = 9_433 DOT
