Update Notes - Core 5.6.3

Fixed

Ecosystem Order Matching

• Partial Fill Fees: Fixed sellers being charged full order fee instead of proportional fee on partial fills - now correctly charges only for the filled amount


• Locked Funds Release: Fixed buyer's funds staying locked forever on partial fills - proportional cost and fee now properly released from locked balance


• Negative Balance: Fixed trade balance going negative due to wallet data type conversion issues - now explicitly converts Decimal types to numbers for accurate arithmetic


• Price Execution: Fixed unfair price matching where buyers always got their price - now properly uses maker's price (whoever placed order first)


• Unauthorized Credit: Fixed orders executing even when wallet updates failed due to insufficient funds - matching now properly aborts when validation fails


• Error Handling: Fixed order matching continuing after wallet update errors - failed matches are now skipped and orders remain available for retry


• Order Cancellation: Fixed partial fill cancellation refunding incorrect amounts - users receiving more than they should when cancelling partially filled orders - now correctly refunds only the remaining unfilled portion

Email Notifications

• Email Verification: Fixed email verification and deposit confirmation emails not being sent - added missing URL shortcode to template validation

Trading Interface

• Balance Display: Fixed trading page showing only available balance instead of total balance - now displays total balance, locked amount, and available balance separately for better clarity


• Chart Updates: Fixed OHLCV (candlestick) data not broadcasting to WebSocket subscribers when orders are matched - corrected subscription filter property order to match frontend subscription format

Improved

Fee Model

• Maker/Taker Fees: Improved fee assignment to use industry-standard maker/taker model


• Market orders now use taker fee (removes liquidity)


• Limit orders that cross spread use taker fee (removes liquidity)


• Limit orders that rest on book use maker fee (adds liquidity)


• Previous behavior incorrectly assigned fees based on buy/sell side only

Order Matching

• Proportional Fees: Enhanced fee calculations to properly handle partial fills


• 10% order fill now charges 10% of the fee (was charging 100% before)


• Locked funds released proportionally including fee portion


• All calculations maintain 18 decimal precision for accuracy

Wallet Operations

• Balance Integrity: Improved wallet update logic to prevent balance discrepancies


• Fresh wallet data fetched before each update to prevent stale data bugs


• Separate handling for order creation/cancellation vs order matching


• Both balance and locked funds (inOrder) validated before updates

Balance Display

• Wallet Information: Enhanced wallet endpoint to return comprehensive balance details


• Total balance (balance + inOrder)


• Amount locked in orders (inOrder)


• Available/spendable balance


• Trading Interface: Improved balance display with clear breakdown of all balance components


• Shows total owned balance prominently


• Displays locked funds with lock icon when applicable


• Highlights available balance in green for easy identification

Added

Trading Features

• Maker/Taker Detection: Added automatic detection of maker/taker status at order creation

### WebSocket Improvements

- **Orders WebSocket**: Created dedicated orders WebSocket service (`orders-ws.ts`) separate from market data WebSocket to prevent message routing conflicts
- **Connection IDs**: Fixed WebSocket messages being sent to wrong connections by using unique connection IDs (`orders-eco`, `orders-spot`, `orders-futures`)
- **Persistent Connection**: Moved orders WebSocket initialization to trading-layout level so connection stays alive even when orders panel is collapsed
- **Message Routing**: Fixed notifications and announcements being sent to all WebSocket connections - now only sent to `/api/user` connection using `sendToClientOnRoute()`
- **Partial Fills**: Fixed partial fills not appearing in real-time - now broadcasts order updates after each match in matchmaking

### Market Panel

- **isEco Flag**: Fixed eco market flag being lost when ticker data updates - now preserves all original market properties using spread operator pattern
- **Property Preservation**: Changed market update pattern from manual reconstruction to spread operator (`{...market, ...tickerUpdates}`) to prevent losing properties

## Improved

### Trading Interface

- **Compact Layout**: Optimized column width with `min-w-[120px]` for better space utilization
- **Percentage Indicator**: Shows fill percentage (e.g., "2%") next to progress bar for instant clarity

### Fee Handling

- **Taker/Maker Fees**: Properly passes market-specific taker and maker fees from market metadata to order forms
- **Dynamic Fee Rates**: Fees are now pulled from market configuration instead of being hardcoded
- **Fee Transparency**: Users can see exact fee amount before placing orders

- Automatic reconnection handling
- Message caching for late subscribers
- **Message Broker Improvements**: Enhanced `sendToClientOnRoute()` method for route-specific WebSocket messaging

### Real-time Order Updates

- **Partial Fill Broadcasting**: Orders now broadcast updates after each match in the matching engine
- **Live Progress**: Users see their orders getting filled in real-time with visual progress indicators
- **Multi-user Updates**: Both buyer and seller receive instant updates when orders partially fill

## Technical Improvements

### Code Quality

- **Removed Debug Logs**: Cleaned up verbose console logging from production code:
- Ecosystem orders API logs
- Scylla query execution logs
- Orders WebSocket connection logs
- Trading layout initialization logs
- **Better Error Handling**: Kept only essential error logging for debugging real issues

Critical Fixes​

Withdrawal Balance Calculation​

• Fixed NATIVE EVM token withdrawal fee calculation - Gas fees are now correctly paid FROM the withdrawal amount instead of being added on top
• Affected chains: ETH, BSC, POLYGON, FTM, OPTIMISM, ARBITRUM, BASE, CELO, RSK, AVAX
• Previously: totalToDeduct = withdrawAmount + platformFee + gasFee (incorrect)
• Now: totalToDeduct = withdrawAmount + platformFee (gas paid from withdrawal itself)

Max Withdrawal Calculation​

• Added gas fee estimation for NATIVE EVM tokens in max withdrawal endpoint
• Max withdrawal now subtracts estimated gas fee to prevent "Insufficient funds" errors
• Formula: maxAmount = availableBalance - platformFee - estimatedGas

String Concatenation Bugs​

• Fixed critical string concatenation issues in balance calculations (7 locations)
• Database stores balances as strings, causing concatenation instead of addition
• Example bug: "0.00689273" + "0.0001" resulted in "0.006892730.0001" instead of 0.00699273
• Added parseFloat() before all arithmetic operations on wallet balances

Floating-Point Precision Errors​

• Added EVM chains to balance precision function
• Fixed precision errors like 0.000890629999999999 displaying instead of 0.00089063
• Added chains: BSC, ETH, POLYGON, ARBITRUM, OPTIMISM, BASE, AVAX, FTM, CELO, RSK (all with 8 decimal precision)

Gas Fee Reconciliation​

• Implemented gas fee reconciliation for NATIVE EVM withdrawals
• Compares estimated vs actual gas used after transaction confirms
• Refunds difference if overestimated, deducts if underestimated
• Keeps database balance synchronized with on-chain balance

Private Ledger Integration​

• Fixed withdrawal balance checks to consider private ledger
• For PERMIT tokens, now checks: availableBalance = wallet_data.balance - offchainDifference
• Prevents users from withdrawing admin fees collected in cross-token exchanges
• Applied in both max withdrawal and withdrawal validation

Monero (XMR) Deposit Processing​

• Fixed XMR deposit deadlock issue
• Created processMoneroTransactionDirect method to handle deposits when wallet is already open
• Prevents "0/120 attempt" stalling on deposits

Technical Improvements​

Balance Checking Logic​

• Changed from checking wallet.balance (total across all chains) to wallet_data.balance (chain-specific available balance)
• Ensures users can only withdraw what's actually available on the specific blockchain

Gas Estimation​

• Implemented proper gas estimation for NATIVE EVM tokens before withdrawal
• Uses 21000 gas limit for standard transfers
• Fetches current gas price from blockchain
• Falls back to conservative estimates if estimation fails

Private Ledger Logic​

• offchainDifference > 0: Admin fees collected (reduces available balance)
• offchainDifference < 0: User credited from exchange (increases available balance)
• Only applies to PERMIT contract type tokens
