Multi-Chain Gas Tank Withdrawal Tool

WHAT IT DOES

This tool evaluates multi-chain gas tank withdrawal readiness, helping users determine if they can withdraw native coins from gas tanks across multiple EVM chains. Given a gas tank contract address, a list of chain configurations (chain ID, RPC URL, native token symbol, and withdrawal amount), and an optional user address, it reads the user's gas balance from the contract, live balance from each chain's RPC, withdrawable amount, withdrawal limit, and whether a withdrawal of the specified amount can be executed. The tool then displays a clear status for each chain—Ready, Low, or Critical—and provides a summary of chains where withdrawal is possible. All data is pulled directly from the blockchain and RPC endpoints in real time, providing a transparent, comprehensive view of gas tank withdrawal readiness.

HOW TO USE

Connect your wallet using the Connect button in the header, or enter a user address manually. Select the target network from the dropdown—Ethereum Mainnet, Polygon, Optimism, Arbitrum One, Base, or Sepolia testnet. Enter the gas tank contract address. Enter each chain configuration on a separate line in the format: chainId,rpcUrl,nativeSymbol,withdrawAmount (e.g., "1,https://eth.llamarpc.com,ETH,0.01" to withdraw 0.01 ETH). Optionally, provide a user address (defaults to connected wallet). Click "Check withdrawal." The tool will fetch the contract balance, live balance, withdrawable amount, withdrawal limit, and canWithdraw status for each chain. Results appear in the card below with a prominent withdrawal status badge (X chain(s) ready for withdrawal, Withdrawal available but limited, or No withdrawal available), a detailed list of each chain showing its withdrawable amount, withdrawal amount, limit, and status, and a summary of chains and withdrawal readiness. Use this information to identify which chains support gas withdrawal.

MULTI-CHAIN GAS TANK WITHDRAWAL VERIFICATION WITH BALANCE AND LIMIT ANALYSIS

The tool provides comprehensive multi-chain gas tank withdrawal verification through multiple on-chain reads and RPC queries. First, it calls getGasBalances() on the gas tank contract with the user address and an array of chain IDs to retrieve all contract-stored gas balances in a single batch call. It then queries each chain's RPC endpoint using getBalance() to get the live native coin balance. The getWithdrawable() function returns the amount the user can withdraw from the gas tank, while getWithdrawalLimit() returns the maximum withdrawal limit. The canWithdraw() function verifies all conditions—sufficient balance, withdrawal amount within limits, and any contract-specific requirements. The overall withdrawal status is determined by checking canWithdraw for each chain—Ready if true, Low if withdrawable amount is positive but insufficient, Critical if no withdrawable balance. All factors are combined to provide a clear, actionable view of multi-chain gas tank withdrawal readiness with detailed per-chain analysis.

WHAT IT CANNOT SEE

This tool cannot guarantee withdrawal execution—on-chain conditions may change between the check and the withdrawal transaction. It cannot predict gas price movements or ensure that the withdrawal will complete. It cannot verify off-chain withdrawal conditions or ensure that the gas tank contract is correctly configured. It cannot ensure bridge solvency or detect changes in bridge state that could affect withdrawals. It cannot detect gas manipulation risks or ensure that gas prices are accurate. It cannot assure that the gas tank contract is free from vulnerabilities, bugs, or malicious code. It cannot verify that the gas tank contract address or chain configurations are correct. It cannot detect front-running or other execution risks. It cannot provide financial or legal advice or guarantee that withdrawing gas is safe. All data is provided as-is for informational purposes only; any reliance on the tool's output for withdrawal decisions is the sole responsibility of the user.

PLEASE NOTE

This tool supports EVM-compatible chains only: Ethereum Mainnet (1), Polygon (137), Optimism (10), Arbitrum One (42161), Base (8453), and Sepolia testnet (11155111). Solana, Tron, Starknet, SUI, TON, Aptos, Bitcoin, Cosmos, and XRP are not supported. The tool requires a Web3 provider (MetaMask or WalletConnect) and access to RPC endpoints for the configured chains. It does not store any wallet data, chain configurations, or withdrawal records. All queries are performed directly against the blockchain and RPC endpoints in real time. The tool only provides read-only information and does not execute any transactions. Withdrawal amounts, balances, and limits are contract-defined and RPC-derived values and do not guarantee withdrawal success. Always verify critical data independently through block explorers and consult with financial advisors before making any withdrawal decisions.
