+## Project Overview :page_facing_up:
+
+This application is in response to the [Social Recovery Wallet RFP](https://github.com/w3f/Grants-Program/blob/master/docs/RFPs/Under%20Development/social-recovery-wallet.md)
+
+### Overview
+
+Pass3 is a crypto wallet, engineered for simplicity without compromising security. It leverages Passkeys for effortless wallet setup and employs a social guard system for account recovery in case of device loss. Built as a mobile-first web application, Pass3 ensures seamless functionality across both mobile and desktop platforms.
+
+Pass3 is crafted for Polkadot Ecosystem and seamlessly compatible with the any Substrate-based chain, contributing to interoperability and enhanced functionality across these networks.
+
+As regular Web3 users ourselves, we understand firsthand the complexities and challenges associated with traditional crypto wallets. With Pass3, we aim to tackle these pain points head-on, simplifying the user experience without compromising on security and functionality.

+
+#### Technical Stacks
+
+**Passkeys**
+A passkey is a digital credential that is used as an authentication method for a website or application. The passkeys standard is a type of passwordless authentication, promoted by the World Wide Web Consortium and the FIDO Alliance.

+
+**How to Integrate Passkeys**
+
+**Registration and Wallet Creation**
+
+- The user registers with the application using Apple's Passkey system.
+- A private-public key pair (Sr25519 key pair) is derived from the Passkey.
+- The private key is securely stored in the keystores, and the public key is converted to Ss58 format for use in Substrate Networks.
+
+**Authentication and Usage**
+- When the user wants to perform a sensitive operation, such as signing a transaction, they are prompted to authenticate using biometric data (such as a fingerprint or facial recognition).
+- The biometric data is used to unlock access to the private key.
+- Once authenticated, the application can use the private key to sign transactions or other messages within the Polkadot network.
+- The key pair remains encrypted and inaccessible unless the user authenticates with their biometric data.

+#### Notes
+The wireframe provided are of low fidelity, implying that the final product's design might differ somewhat. Nonetheless, the fundamental logic and features should stay the same.
+
+### Ecosystem Fit
+Pass3 is a wallet specifically designed for the Polkadot Ecosystem. We believe it will significantly enrich the ecosystem. Primarily aimed at entry-level users, Pass3 intends to make the initiation into Web3 as barrier-free as possible. Moreover, we anticipate that Pass3 will elevate the user experience within the Polkadot Ecosystem, relieving users of the burden of key management. Despite the variety of wallets already present in the ecosystem, we're confident that Pass3 will provide a uniquely enhanced user experience.

+## Development Roadmap :nut_and_bolt:
+
+### Overview
+
+- **Total Estimated Duration:** 4 months
+- **Full-Time Equivalent (FTE):**  2.5 FTE
+- **Total Costs:** 40,000 USD
+
+### Milestone 1 - Core functionalities
+
+- **Estimated duration:** 2 months
+- **FTE:**  2,5
+- **Costs:** 20,000 USD 
+
+| Number | Deliverable | Specification |
+| -----: | ----------- | ------------- |
+| **0a.** | License | MIT |
+| **0b.** | Documentation | We will provide both **inline documentation** of the code and a basic **tutorial** that explains how to use the wallet and how it works |
+| **0c.** | Testing and Testing Guide | Core functions will be fully covered by comprehensive unit tests to ensure functionality and robustness. In the guide, we will describe how to run these tests and provide CI/CD setup files as GitHub Actions for code checking, automated testing, and deployment.  |
+| **0d.** | Docker | We will provide a Dockerfile(s) that can be used to test all the functionality delivered with this milestone. |
+| **0e.** | Article | We will provide an article about how we build a keyless wallet with Passkeys. |
+| 1. | Infrastructure | We will provide infrastructure code using Terraform, enabling effortless AWS infrastructure bootstrapping. |
+| 2. | Web Application | We will develop a mobile-first web application that features registration, authentication, and asset management functionalities, as outlined in the provided wireframe. The registration and authentication functionalities logic is described in project detail section. By using the asset management feature, users can view their balances, deposit, and transfer their assets. This can be done through the [balances pallet](https://github.com/paritytech/substrate/tree/master/frame/balances) for native tokens, and the [assets pallet](https://github.com/paritytech/substrate/tree/master/frame/assets) for managing assets on the Asset Hub.|
+| 3. | Backend Services | We will deliver backend services for sign-up, sign-in, and asset management features. |
+
+
+### Milestone 2 — Backup and recovery
+
+- **Estimated duration:** 2 months
+- **FTE:**  2,5
+- **Costs:** 20,000 USD
+
+| Number | Deliverable | Specification |
+| -----: | ----------- | ------------- |
+| **0a.** | License | MIT |
+| **0b.** | Documentation | We will provide both **inline documentation** of the code and a basic **tutorial** that explains how to use the recovery and backup features, how it works and setup guide |
+| **0c.** | Testing and Testing Guide | Core functions will be fully covered by comprehensive unit tests to ensure functionality and robustness. In the guide, we will describe how to run these tests. |
+| **0d.** | Docker | We will provide a Dockerfile(s) that can be used to test all the functionality delivered with this milestone. |
+| 1. | Feature: Social Recovery | We will implement the social recovery setup and management screens as depicted in the above wireframe. To implement this feature, we will use [social recovery pallet][https://github.com/paritytech/substrate/tree/master/frame/recovery], which allows users to setup social guards in the case that they lose device access. |
+| 2. | Feature: Recover Wallet | We will implement recover screens as depicted in the above wireframe.|
+| 3. | Feature: Encrypted Cloud Backup | We will implement feature allow user encrypt and sync the backup key to the cloud storage. The back-up key will be encrypted by AES-256 algorithm.|
+| 4. | Feature: Notifications | We will implement email notifications for balance updates and security alerts, such as recovery initiation prompts. This will help improve the safety of using the recovery pallet, as mentioned in these [safety considerations](https://github.com/paritytech/substrate/tree/master/frame/recovery#safety-considerations). |
+| 5. | Backend Services | We will implement the backend services for 1, 2, 3, 4 sections  |
+
+## Future Plans
+Our plan is to roll out the product in the Polkadot Ecosystem following each milestone. This will allow us to gather feedback to refine existing features and incorporate additional ones if needed.
