Expanded WalletConnect/Web3 processing in core wallet modules and service integration points. Partially migrated submodule logic to pure C++ in cellframe-ui-sdk and cpp-cellframe (part of Qt/QML handling moved to C++ backend flows). Moved part of request, session, and transaction logic from the UI layer to C++ implementation. Updated transaction-related modules (Wallet, TxExplorer) for more stable backend-side processing. Add new web3 API methods for WebDEX. Reworked WalletConnect/Web3 user flows with dedicated popups for connect, confirmation, and error states. Updated session confirmation UI and shared QML interaction components. Added an address book flow for payments: contact selection/editing and QR usage. Added DEX web dApp. Added new Web menu in mobile interface. Fixed Web3 queue and request handling issues, reducing failures in edge-case scenarios. Updated staking and shared wallet Web3 methods. Expanded unit tests for critical Web3 scenarios and regression protection.

Changelog - Cellframe Wallet 4.6-123 Fixed application freeze when the node is unavailable — managers (fee, wallets) subscribe to the disconnect signal, stop timers, and check connectivity before each request; atomic queue limit of 32 tasks; interruptible HTTP requests Fixed critical multithreading issues — HTTP response handlers were being called from multiple threads at the same time; all responses are now safely dispatched to the main thread; fixed blocking on Windows when launching processes simultaneously Periodic node status polling no longer freezes the UI Fixed the selected wallet not being preserved when switching modes and after restart Fixed duplicate network entries — duplicates are removed before setting the list into the model Fixed an issue where the interface did not pick up the Cellframe Node initialization status after startup and kept showing “Offline - cached data” until the GUI was restarted Replaced the “Offline - cached data” text in the application header with “Offline” when the node is disconnected Fixed the infinite loading animation in Last Actions for password-protected wallets (activated/deactivated) Fixed the network status animation for the resync_chains state — the status is now hidden during resync TX Explorer: a lock illustration and the “Unlock wallet” button are shown for password-protected wallets Fixed Shared Funds Sign getting stuck in Last Action: the signature operation now finishes immediately after successful mempool submission and no longer waits for blockchain finalization. Fixed DapTxSharedSign queue handling: signature operation now fully bypasses the transaction queue and executes instantly, since it does not create an independent blockchain transaction. Fixed incorrect Take amount display in Pending (+0.0): mempool parsing was aligned with the actual node response format, so operation data is no longer lost. Fixed incorrect Hold amount display in Pending (-0.0): corrected type/amount rendering in Take history and restored proper validator and network fee display. Fixed infinite stuck state in Pending withdrawals: the waiting list is now updated unconditionally for each shared fund, including cases with empty waiting_operations_hashes. Optimized shared funds data retrieval: switched to wallet shared list -verbose -addr, removed duplicate per-account wallet shared info requests, and introduced a single sequential request queue. Fixed long tag rendering in details: label and value are separated, value uses ElideMiddle, and tooltip shows only the full tag value. Fixed wallet selector behavior in New shared fund: active wallet and token data now refresh correctly, the form stays open, and only wallet-dependent fields are reset. Fixed Validator fee input handling in Request withdrawal: value is applied immediately without pressing Enter and is consistently used in confirmation and submission. Added a persistent Create shared fund button when the shared funds list is not empty (with node availability and active wallet checks). Fixed owners address rendering for Hold: multiple addresses are now shown line by line with correct formatting and copy behavior. Added token balance display next to Add funds, with auto-refresh on wallet, token, and data changes. Fixed Add funds reset on wallet switch: amount is cleared correctly, and token selector switches to the first available token of the selected wallet. In Refill, the To field now shows the Hold transaction address instead of hash; text, tooltip, and copy action were updated (Address copied). Refill confirmation now shows both Hash and Address; hold_address is passed from UI through controller to processor. Take confirmation now shows both Hold hash and Hold address In Request withdrawal, the From field now shows the Hold address (addr) instead of transaction hash, with a safe fallback to txHash. In the successful Hold creation screen, shared account address is now shown instead of tx hash

Changelog - Cellframe Wallet 4.6-102 Enter key now submits the form in all password dialogs (activation, creation, wallet creation); in two-field forms it moves focus from password to confirmation Non-Latin keyboard layout detection: warning with red highlight when non-Latin characters are entered; auto-switch to Latin on mobile platforms Warning text moved above input fields in vertical mode for visibility when the keyboard is open Fixed node mode selector (Local/Remote/Light) — highlight indicator was invisible for some users due to unreliable rendering mechanism Sync network and On network buttons are now disabled during node initialization (LOADING state), displayed in grey with "Off network" text Fixed Shared Funds: transaction list from Light mode no longer persists after switching to Local Fixed loader on Transactions page — partial transaction list no longer visible during refresh Fixed successful unlock message shown without internet connection while wallet remains locked Fixed log spam: "Network or token not set:" entries no longer written
