Smesh Signer Setup - Sync Preference
Smesh Signer always encrypts sensitive data like private keys and site permissions independent of the chosen sync mode. Sync : Mozilla Firefox Your encrypted data is synced between browser instances. You need to be signed in with your account. Offline Your encrypted data is never uploaded to any servers. It remains in your local browser instance.
Important for Cashu wallet users

Browser sync storage is limited to ~100KB shared across all data (identities, permissions, relays, and Cashu tokens).

If you plan to use the Cashu ecash wallet with significant balances, choose "Sync OFF" which provides ~5MB of local storage (enough for ~18,000+ tokens vs ~300-400 with sync).

Note: Cashu tokens are bearer assets. If you lose your vault backup, you lose your tokens permanently. Make sure to configure regular backups.

Your preference can later be changed at any time.
