Targets the Sia network post-v2 hardfork (activated June 6, 2025) and post-Final Cut (December 2, 2025) — full v2 consensus support.
Your 12-word seed is the only way to recover your wallet. Sia Wallet cannot reset your password or recover a lost seed — no self-custody wallet can. Back up your seed in two physical locations before funding the wallet.
- Paid "seed recovery" services are scams — do not use them.
- Legacy 28/29-word Sia-UI seeds are still valid for deriving old addresses but must be migrated to the 12-word BIP39 format (built-in migration assistant, first run) before they can transact on the post-v2 network.
- Private keys generated locally never leave your machine unless you explicitly export them (air-gapped signing) or use a connected Ledger, where keys never leave the hardware device.
