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.
Wrapped hardcoded strings in rewards app with translation keys.
German (de): Deposit changed from "Anzahlung" to "Empfangen"; added missing Share → "Teilen".
Added --key and --keys flags to i18n tooling for targeted re-translation.
