What Sia Wallet is
Sia Wallet is a non-custodial desktop wallet for Siacoin (SC) and Siafunds (SF). It runs natively on Windows, macOS, and Linux. Native iOS and Android ship within 90 days of the desktop v2.12.0 release.
The wallet is built on walletd — the reference Sia wallet maintained by The Sia Foundation since 2024. We fork walletd under its MIT licence, add a consumer-first UI layer, a guided first-run wizard, a legacy seed migration assistant, native Ledger support without browser flags, and a default lite-mode sync. Every walletd server feature — three index modes, JSON API, multi-wallet server, Docker deployment — remains available under Advanced Settings.
Sia Wallet is an independent project. It is not affiliated with, endorsed by, or operated by The Sia Foundation. Fixes and improvements made downstream are contributed back to upstream walletd where applicable.
What we do differently
Non-custodial by design
Your 12-word seed and private keys are generated locally and never leave your device. We cannot move your funds, freeze your wallet, or reset your password. Self-custody is the model.
Read the safety FAQ →Zero telemetry
No analytics, no tracking, no crash reporter on by default. The optional crash reporter ships disabled with a plain-English consent screen describing exactly what gets sent. Your wallet addresses never leave your machine.
Privacy and telemetry policy →Non-custodial always
Keys are generated locally and stored encrypted on your device. Sia Wallet cannot move your funds, reset your password, or recover a lost seed. There is no support team that can override self-custody — that is the point, not a limitation.
Recovery guide →Upstream attribution
Sia Wallet is an MIT-licensed fork of walletd. The Sia Foundation authored walletd and maintains the protocol. We credit them in every release, contribute fixes upstream, and publish a CONTRIBUTORS file naming all original walletd authors.
Public issue tracker
Every bug report, feature request, and security advisory is handled in the public repo at siawallet.tech. Security-sensitive reports can be sent to the GPG-encrypted contact address published in SECURITY.md.
About Siacoin and The Sia Foundation
Siacoin (SC) is the native utility token of the Sia network — a decentralised cloud storage blockchain co-founded by David Vorick and Luke Champine at an MIT hackathon in 2013 and launched in 2015. Siacoin pays hosts for storage and collateralises storage contracts. Circulating supply is approximately 56 billion SC.
The Sia Foundation is a US-registered 501(c)(3) non-profit that maintains the Sia protocol, consensus, and core open-source software, including walletd, renterd, and hostd. The Foundation is funded by a perpetual Siacoin subsidy adopted by network hard fork in February 2021. The Sia v2 hardfork activated on June 6, 2025 at block 526,000. The v2 Final Cut cleanup fork finalised the network on December 2, 2025 at block 552,100.
Privacy and telemetry
Sia Wallet ships with no analytics framework, no crash reporter enabled by default, and no phone-home behaviour. Your wallet addresses and balances stay on your machine.
The optional crash reporter is off by default. Turning it on shows a consent screen describing exactly what would be sent: the wallet version, the operating system name and version, the stack trace, and a short description of what you were doing. No addresses, no seed material, no balance, no transaction data. The crash reporter endpoint is documented in the repository and can be audited.
Common trust questions
Is Sia Wallet the official Siacoin wallet?
Sia Wallet is an independent consumer-grade fork of walletd, the reference wallet from The Sia Foundation. 'Official' in the cryptocurrency world typically means 'maintained by the foundation.' walletd is the foundation's software. Sia Wallet is our consumer product built on it — open-source, MIT-licensed releases,
Has Sia Wallet been audited?
The Sia consensus code and walletd core that Sia Wallet is built on are maintained by The Sia Foundation with audits documented on sia.tech. Sia Wallet's added UI layer has not yet received a paid independent audit — one is planned within 12 months of the v2.12.0 launch. Until then, the source is public and reviewable at siawallet.tech.
Is siawallet.com the same site?
No. Sia Wallet is hosted at siawallet.tech and its source is at siawallet.tech. Other domains using similar names are not operated by this project. Alwaystech Download page.
Why MIT licence and not GPL?
Upstream walletd is MIT-licensed. Staying on the same licence keeps contribution flowing both ways — our improvements can go back upstream, and their updates can flow to us, with no licence-compatibility friction.
