Project Summary
Overview
Filament will be an open-source Filecoin wallet designed for truly native cross-platform operation across Windows, macOS, and Linux, as well as web environments, all built from a single unified codebase.
Once developed, it will enable users to create or import wallets, send and receive FIL with intelligent smart routing across all Filecoin address types (f1, f2, f4, and 0x), and view transaction history.
Filament aims to become the default, community-driven Filecoin wallet, delivering a secure, intuitive, and accessible experience for newcomers, everyday users, and developers.
Problem
Filecoin's growth is hindered by the lack of a unified, user-friendly wallet. Existing solutions are fragmented—browser extensions, CLI tools, or Ethereum-based wallets—causing confusion and inconsistent experiences. Managing multiple address types (f1, f2, f4, 0x) is complex, complicating onboarding and driving users to non-native tools, which limits the adoption of Filecoin’s unique features.
Solution
Filament will deliver a robust, cross-platform wallet tailored for Filecoin, featuring:
- Seamless account management: Create or import wallets using mnemonics or private keys.
- Smart routing for FIL transfers: Automatically detect and handle all Filecoin address types (f1, f2, f4, 0x) for error-free transactions.
- Transaction history: View detailed records with integrated explorer links.
- Future-proof design: Support upcoming FVM dApp integrations via WalletConnect.
- Security and efficiency: Employ encrypted storage and a single codebase for consistent web and desktop builds.
This streamlined approach will prioritize simplicity, security, and compatibility, making Filecoin more accessible and practical for all users.
Impact
Once developed, Filament will transform user interaction with Filecoin by offering a reliable, all-in-one wallet.
It will simplify onboarding, promote secure self-custody, and reduce reliance on fragmented or Ethereum-centric tools. As an open-source, official-grade solution, Filament will strengthen the Filecoin ecosystem, making FIL more practical for daily transactions and dApp use.
Outcomes
The primary deliverable will be a fully functional, cross-platform Filecoin wallet supporting account creation, FIL transfers with smart routing, transaction history, and multi-network compatibility.
Success will be measured by user adoption (targeting 1,000+ early adopters in the first few months post-launch), developer integrations, and community feedback via GitHub, forums, and surveys.
Adoption, Reach, and Growth Strategies
Filament will target Filecoin users, dApp developers, storage providers, and ecosystem contributors.
Adoption will be driven through outreach on Filecoin Slack, X, Discord, and online forums. Partnerships with FVM projects will integrate Filament as a preferred wallet in dApps. Open-source collaboration, tutorials, hackathons, and beta programs will fuel growth and iteration.
