Transaction detail view silently dropped OP_RETURN messages and coinbase
scriptSig text (e.g. pool tags), since TransactionInspector discarded
scriptPubKey/scriptSig bytes once no destination address could be derived.
Each output/input is decoded independently, so multiple OP_RETURN outputs
in one tx are all shown.
ToAccount's InvalidDataException paths (corrupted mnemonic/xprv/xpub,
a document with no key material at all) and the equivalent guards in
NewFromXpub/NewFromXprv/NewFromWif had no coverage — these are the
checks that turn a damaged wallet file into a clear error instead of
an unhandled exception or, worse, a silently wrong account.
builder.Verify's failure branch (the safety net right before a signed
tx would be returned to the caller) had no test: an absurd fee rate
now proves the "Invalid transaction: ..." path fires instead of
silently returning a policy-violating transaction.
Empty entry list rejection, GetPublicKey boundaries (mirroring the
existing GetPrivateKey tests), and explicit assertions that change and
out-of-range indices always fall back to the first imported address —
never to an address the wallet doesn't hold keys for.
- AppPaths: data-root resolution, per-network paths, wallet file listing.
- TransactionFactory: legacy/P2SH/segwit destinations, multi-UTXO selection,
dust change absorbed into fee, and a golden txid for the PSBT signing path
(RFC 6979 makes it deterministic; the builder's own output shuffling for
privacy makes anchoring the vector at the top-level Build() unreliable).
- PropertyTests: Slip132 roundtrip for every script kind and network,
WalletDocument JSON roundtrip with arbitrary labels/contacts, Scripthash
cross-checked against an independent SHA-256 computation.
- StorageTests: regression cases for the IsEncrypted fix.
- Removed CS8602/CS8604 nullable warnings from existing address/loader tests.
ElectrumClient, WalletSynchronizer, TransactionInspector, CertificatePinStore
and peer discovery went from 0% coverage to close to full coverage, all
against the fake ElectrumX server:
- ElectrumClient: request/response correlation under load, server errors,
notifications, disconnection, cancellation, SSL handshake with TOFU pinning.
- WalletSynchronizer: gap-limit scanning, UTXO/history reconstruction,
unconfirmed/immature balances, busy-retry, disk-cache reuse, and the
security-critical path where a lying server fails Merkle verification and
the sync must abort.
- TransactionInspector: fee calculation from resolved inputs, mine/theirs
attribution, RBF flag, coinbase handling, degraded paths when a previous
transaction can't be resolved.
- CertificatePinStore: TOFU pin/match/mismatch/reset, corrupted-file fallback.
- ServerRegistry: peer discovery and persistence via DiscoverAsync.
- UpdateChecker: release-tag parsing and semver comparison.
Coinbase outputs require COINBASE_MATURITY + 1 = 121 confirmations before
they can be spent. The consensus rule (palladiumcore tx_verify.cpp) is
nSpendHeight - nHeight >= 120; the +1 adds one block of safety margin,
matching the Qt wallet (wallet.cpp: COINBASE_MATURITY+1). Regular UTXOs
require MinConfirmations (6 on mainnet, 1 on testnet/regtest — wallet
policy, no consensus rule).
Changes:
- ChainProfile: add CoinbaseMaturity and MinConfirmations fields
- ChainProfiles: mainnet CoinbaseMaturity=120 / MinConfirmations=6;
testnet/regtest inherit 120, override MinConfirmations=1
- PalladiumNetworks: align NBitcoin Consensus.CoinbaseMaturity to 120
- CachedUtxo: add IsCoinbase flag (ElectrumX listunspent does not expose
this; derived from Transaction.IsCoinBase on the raw tx)
- WalletSynchronizer: set IsCoinbase during local UTXO reconstruction
- TransactionFactory.Build: add tipHeight param; filter by threshold;
error reports reason (immature coinbase with X/121 counter, under-
confirmed regulars with best-seen count, mempool amounts)
- All Build() call sites updated (App, Donate, CLI)
- Two new tests: coinbase maturity boundary (119→220 tip) and mainnet
min-conf boundary (5→6 confirmations)
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.
Introduce IWalletAccount interface to abstract HD, imported-xprv, WIF,
and watch-only account types. HdAccount implements the interface; the
new ImportedKeyAccount handles lists of WIF keys with fixed addresses
(no gap scanning, change returns to first address).
WalletLoader gains three factory methods:
- NewFromXpub: watch-only from SLIP-132 xpub/ypub/zpub
- NewFromXprv: spendable from SLIP-132 xprv/yprv/zprv
- NewFromWif: spendable from one or more WIF private keys
WalletDocument gains optional AccountXprv and WifKeys fields; AccountPath
and AccountXpub become nullable (absent for WIF wallets). IsWatchOnly
updated to cover all non-signing wallet kinds.
TransactionFactory and CLI OpenWallet() updated to IWalletAccount.
12 new unit tests in ImportedKeyAccountTests cover factory round-trips,
address derivation, and watch-only detection.
Replace the silent (long) cast with an explicit fractional check:
if value * factor has a non-zero remainder, TryParseIn/TryParseCoins
return false. The caller already shows "Importo non valido." to the
user, so no UI change is needed.
Covers TryParseIn (all units) and TryParseCoins. Adds CoinAmountTests
with valid and invalid cases including the triggering example (1.9 sat).
On first launch (no data yet, no portable dir, no pointer file),
the wizard now shows a new step-0 screen asking where to store
wallets, config and certificates.
AppPaths changes:
- DefaultDataRoot() → ~/.PalladiumWallet (home, always writable)
- IsDataLocationConfigured() → true when portable / override / pointer
already written / legacy or default already has data
- ConfigureDataLocation(root) writes a bootstrap pointer file and
creates the directory
- DataRoot() resolution order: override → portable → pointer → legacy
(has data) → default
ViewModel: new StepDataLocation step, UseDefaultDataLocationCommand,
ApplyDataLocation(root) (also called from View's folder picker).
View: new wizard panel with description, default-path display, two
buttons (use default / choose folder); folder picker via
StorageProvider.OpenFolderPickerAsync.
Loc: add wiz.data.* keys (6 languages); fix fallback language "it"→"en";
update test assertion accordingly.
Add global AppConfig (config.json, blueprint §8) persisting language
and amount unit. CoinAmount gains unit-aware formatting and parsing
(PLM, mPLM, µPLM, sat), applied everywhere amounts are shown or
entered, including the send form. New Loc i18n layer (it/en) with
live-updating XAML bindings covering menu, wizard, wallet panel and
status messages.
The Impostazioni menu opens a dropdown with separate Lingua and Unità
entries (radio-checked submenus, applied and saved on click), ready to
host future settings.
TransactionFactory now selects only confirmed UTXOs (height > 0), so
mempool funds are visible as pending balance but never spendable, with
a clear error when only unconfirmed funds are available. GUI and CLI
labels updated to "in attesa di conferma (non spendibile)".
