Balance/history now render as soon as tx downloads finish instead of
blocking on every historical Merkle proof, critical for mobile where
proof-checking can take much longer than the download itself. Proofs
continue to be checked in the background and each tx's Verified flag
catches up progressively; header ranges are now fetched in batches
(blockchain.block.headers) instead of one call per header to keep this
fast over high-latency links.
Coin selection (UtxoSpendability.IsSpendable) refuses to spend a UTXO
until its Merkle proof is actually checked, regardless of confirmation
count, so a server that fabricates a confirmed balance can get it
displayed early but never spent before the forgery is caught. The disk
cache only ever persists the fully-verified end state of a sync.
UI surfaces the new PendingVerificationSats/SpendableSats split with a
"verifying..." badge, and the sync save now runs off the UI thread to
avoid freezing on slower hardware.
Extract confirmation-threshold logic into UtxoSpendability (shared by
TransactionFactory and WalletSynchronizer) and use it to compute
ImmatureSats, so coinbase/under-confirmed amounts are shown separately
from spendable balance in the GUI and CLI instead of being lumped into
"confirmed".
SPV is the only verification method the wallet uses, so showing it as a
badge adds no information — if a transaction appears confirmed, it has
already passed Merkle verification.
- Remove the SPV chip from the transaction detail overlay
- Remove the Verificata column from the history list (desktop and mobile)
- Drop VerifiedText property from TransactionDetailsViewModel
- Drop the Verificata field from HistoryRow
- Remove the orphaned tx.verified loc key
Replace the direct private-key display in the address detail overlay with a
two-step reveal flow:
- Unencrypted wallet: clicking Show reveals the WIF key immediately.
- Encrypted wallet: clicking Show opens a modal password-prompt overlay; the
key is displayed only if the entered password matches the wallet file
password; a wrong password shows an inline error without closing the prompt.
Hiding the key (Hide button) clears the revealed state. Closing the address
overlay or opening a different one always resets both the reveal state and
the password prompt, so no sensitive material lingers between sessions.
Translate every Italian /// XML doc comment, <!-- --> XAML comment, and
// inline comment to English across all source files (Core, App, tests).
Add the language policy to CLAUDE.md (conversation Italian; all code
and docs English). Update one test assertion that checked an Italian
exception message that was also translated.
Add two new import paths to the setup wizard:
- "Importa xpub / xprv": accepts any SLIP-132 key (xpub/ypub/zpub or
xprv/yprv/zprv), auto-detects script type from the version prefix,
and saves a watch-only or fully-spendable HD account accordingly.
- "Importa chiave WIF": accepts one or more WIF private keys (one per
line), goes through script-type selection, and saves an ImportedKeyAccount.
WizardFlowKind enum (New, Restore, ImportXkey, ImportWif) governs which
steps are shown; WizardBack() updated for all four flows. OpenLoaded()
updated to accept IWalletAccount and display wallet kind tags
(watch-only / imported) in the network info line.
Localization keys added for all six languages (it/en/es/fr/pt/de).
ViewModel._account changed from HdAccount? to IWalletAccount?.
