What is Sia's walletd?
Sia's walletd is the flagship wallet software developed by the Sia Foundation for securely managing Siacoins (SC) and Siafunds (SF). Built with both flexibility and advanced security in mind, walletd serves as the primary application for users, miners, and exchanges to store, send, receive, and manage Sia assets within the decentralized Sia ecosystem

Key Features
- Multi-Asset & Multi-Wallet Support: walletd allows users to interact with both Siacoin and Siafund tokens and can manage multiple wallets, suitable for miners, exchanges, and everyday users12.
- Security Integrations:
- Hot and cold wallet modes (local or air-gapped usage)
- Hardware wallet integration, especially with Ledger devices, providing enhanced security for private key management12.
- Multi-signature support for collaborative custody and institutional requirements345.
- Modern UI and Accessibility: walletd ships with a user-friendly web interface for desktop applications (Windows, macOS, Linux) as well as a command-line daemon option. This supports both graphical and headless (API) integrations12.
- Network Monitoring: Real-time monitoring of the Sia blockchain for wallet-relevant events, balance updates, and transaction history1.
- Flexible Key Management: Enables import/export of standard 12-word seed phrases, legacy (siad) 28-word phrases, and hardware wallet derivations, making migration easy2.
Architecture & Operation
- Client-Server Model: walletd’s design separates the wallet’s core server from its user interfaces, allowing remote access from any device while keeping private keys local and secure.
- Standalone/Containerized Deployment: Can be run as a standalone binary or Docker container, making it production-ready for exchanges and advanced integrators6.
- API-driven: Developers can leverage walletd’s powerful JSON API for automated workflows, integrations, or building additional user interfaces2.
Recent Improvements & Roadmap
- Performance and Usability Upgrades: Recent updates have improved balance refresh rates, address generation, and added robust API testing. There is ongoing support for V2 transaction formats as the Sia protocol evolves7.
- V2 Hard Fork Preparation: walletd is being updated to support new protocol features like Utreexo (for faster syncs and smaller state), which will allow full Sia nodes—walletd included—to run efficiently on devices like smartphones or embedded hardware7.
- Desktop: Windows, macOS (Intel and Apple silicon), Linux (amd64, arm64)
- Command Line: Downloadable CLI binaries for all major platforms
- Web Interface: Embedded in the desktop app, also available as a web app with the server12.
Getting Started & Documentation
- Official Software & Guides: Users can download walletd from the official Sia site and find step-by-step guides for each operating system, including detailed instructions for setup, backup, and recovery:
In summary:
walletd is Sia's secure, flexible, and future-proof wallet solution for managing Siacoin and Siafunds. It’s designed for both regular users and enterprise-grade integrations, prioritizing security (hardware wallet support), usability (modern UI), and scalability (support for Sia's evolving protocol)
