The Siacoin wallet for Windows, macOS, and Linux. Non-custodial, open source, native Ledger — install in 60 seconds.
For years, Siacoin holders chose between Sia-UI — retired in 2024 when the Sia Foundation split its stack into renterd, hostd, and walletd — and walletd itself, which is powerful but developer-first. Neither closed the gap a consumer-grade wallet should close.
Sia Wallet is the answer. It is an MIT-licensed fork of walletd with a guided first-run wizard, a one-flow migration assistant for legacy 28 and 29-word seeds, native Ledger support without experimental browser flags, and mobile apps on a 90-day roadmap. Start your Sia Wallet download for Windows, macOS, or Linux below — the repository is public from day one.
Full nodes take days and 256 GB of disk. Sia Wallet starts in lite mode by default — connects to verified consensus nodes for balance queries, keys generated and stored locally. Full-node mode is a single toggle in Advanced.
How instant setup works →Sia v2 broke 28 and 29-word seeds. The built-in assistant imports your old seed locally, generates a new 12-word BIP39, and walks the funds move in one flow. Plaintext never leaves your machine.
Legacy seed migration assistant →No experimental browser flags. No driver hunts. Plug in your Nano S or Nano X, unlock, open the Sia app, and Sia Wallet detects it. Keys never leave the device. Both USB and Bluetooth supported.
One-click Ledger support →MIT-licensed source at siawallet.tech. Forked from walletd, the reference Sia wallet from The Sia Foundation. Auditable by anyone, free for personal and commercial use.
Read the about page →Native iOS and Android ship within 90 days of launch. Lite-mode only — no blockchain download on phones. Face ID, Touch ID, or fingerprint required on every send. Pairs with desktop via QR code.
Sia Wallet mobile roadmap →Sia Wallet ships with no analytics, no crash reporter, no phone-home. The opt-in crash reporter is off by default with a plain-English consent screen describing exactly what gets sent.
Privacy and telemetry policy →Three operating systems. Open source. Non-custodial. One download away.

Sia Wallet is an MIT-licensed fork of walletd with a consumer-first UI layer added on top. Every walletd feature — three index modes, JSON API, multi-wallet server, Docker deployment — remains available under Advanced Settings. Fixes and enhancements are offered back upstream to The Sia Foundation where applicable.
Download only from siawallet.tech/download. These are the two official mirrors and serve the identical file. Avoid third-party software aggregators — they are slower to update and may distribute outdated versions.
Yes. Ledger Nano S and Nano X are supported natively over USB and Bluetooth — no browser flags required. Install the Sia app on your Ledger once via Ledger Live, plug in the device, unlock with your PIN, and Sia Wallet detects it automatically. Private keys never leave the hardware wallet.
Not directly. Sia v2 replaced legacy 28 and 29-word seeds with 12-word BIP39 seed phrases. Sia Wallet's built-in migration assistant imports your old seed locally, generates a new 12-word seed, and walks you through transferring your balance. The plaintext seed never touches the network.
