  • Refunds the difference if gas was overestimated

• Changed gas estimation for native EVM tokens to run before withdrawal, falling back to a conservative estimate

Fixed

Withdrawal System

• Fixed native EVM token withdrawal fee calculation — gas fees are now correctly paid from the withdrawal amount
  • Affected chains: ETH, BSC, POLYGON, FTM, OPTIMISM, ARBITRUM, BASE, CELO, RSK, AVAX
• Fixed max withdrawal calculation to include gas fee estimation, preventing "Insufficient funds" errors
• Fixed critical balance calculation errors that caused incorrect withdrawal amounts
• Fixed floating-point precision errors in EVM chains (e.g. displaying 0.000890629999999999 instead of 0.00089063)
• Fixed a Monero deposit deadlock that prevented deposits from processing

Private Ledger Integration

• Fixed withdrawal balance checks to properly consider private ledger balances
• Fixed users being able to withdraw admin fees collected in cross-token exchanges
