---

Bug Fixes

P2P Exchange

• Escrow verification not triggering after swipe-to-escrow — reordered EscrowTransfer.vue so escrowPendingOrder() is awaited before emitting success, preventing a race that left the page stuck in escrow-bch state until manual navigation. (#731)

Wallet / Transactions

• Token metadata inconsistency between home/asset-list and transaction history resolved via BCMR store lookup and background enrichment.
• Address scan — cached master HD node with TTL, fixed usedDiscovery fallback, and added balance refresh.
• Imported wallet showing zero balance — getMnemonic(index) now tries hash-based storage before migration flag, fixing mnemonic retrieval for wallets imported from other wallets.
• Multisig UTXO type mismatch — false "Insufficient BCH balance" errors fixed by converting targetSatoshis to bigint before UTXO selection.
• WalletConnect message signing — fixed "buffer length error" by replacing BCHjs signer with libauth; changed response format from hex to base64 to match personal_sign expectations.

UI / Display

• Safe inset bottom for fixed-bottom class — fixed marketplace cart/chat button spacing at the bottom of the screen. (#717)

---

Localization

• Added ~300 new Nostr chat translation keys across 17 locales.
• Added missing translation keys for apps page, chat profile prompt, and ResetChatDialog.

---

v0.24.6

Release notes

Bug Fixes

Multisig

• UTXO type mismatch: Fixed false "Insufficient BCH balance" errors by converting targetSatoshis to bigint before passing to selectUtxos, and normalizing types throughout UTXO selection logic.
• Wallet file download crash on mobile: Fixed app crash when exporting/downloading wallet files on native mobile platforms.
• Wallet watcher + WC session error handling: Improved robustness with early-return guard for falsy walletId, try/catch around getWalletWcSessions with 404-specific handling, and proper fallbacks for missing coordination server data.

WalletConnect

• Message signing: Fixed "buffer length error" by replacing BCHjs signer with libauth; changed response format from hex to base64 to match personal_sign expectations from dapps. Added address verification between client's expected signer and the session signer address.
• Disconnect race condition: Prevented race condition in @wizardconnect/wallet during disconnect.

Reservations / Lift Token

• Discount display: Extracted getDiscountedPriceUsd/getOriginalPriceUsd into shared utilities to fix inconsistent discount display between PurchasesTabPanel and PurchaseInfoDialog.
• Reservation confirmation: Immediately populate wallet's public key on new reservations so confirmation succeeds on first try. Added comprehensive error handling around confirmReservation(), initializeVestingContract(), convertDateToBlockHeight(), getAddressPath(), and libauth wallet init.
• Oracle data: Added error handling around getOracleData() and fixed walletBalance value error with optional chaining.
• Missing i18n keys: Added translation keys for FailedToGetContractData and FailedToGenerateAddress.

UI / Display

• BCH receipt amount: Grayed out trailing zeros in BCH amounts with all-zero decimals; adaptive font-size for receipt amounts.
• Token fiat prices: Refresh fiat prices for all displayed tokens, not just favorites.

QR Scanning

• Normalized UR QR comparisons: Fixed QR content comparison by normalizing UR strings before comparison.

Wallet Import / Mnemonic Storage

• Imported wallet showing zero balance: Fixed mnemonic retrieval failing for wallets imported from other wallets. getMnemonic(index) now also tries the new hash-based storage scheme even before migration is flagged, so wallets stored via the restore flow (which use only hash-based keys) are immediately found instead of returning null.
• Old-scheme key overwrite: Fixed storeMnemonic overwriting wallet 0's old-scheme mnemonic when called with a wallet hash string during import. Old-scheme backup storage is now skipped when the correct index isn't known.

Localization

• German (de): Changed Deposit from "Anzahlung" to "Empfangen" to match normal wallet terminology. Added missing Share → "Teilen".
