eth_estimate_gas: web3.exceptions.ContractLogicError: execution reverted: Failed to submit transaction: insufficient balance for transfer about zksync2-python HOT 5 CLOSED

You are write when it comes to gas_limit it should be named l2_gas_limit (your PR that makes those changes is already merged). Also when gas_limit is not provided, the fixed default value of 10_000_000 is used. This is not correct anymore and the gas limit should be estimated using zks_estimateGasL1toL2. The provider does not have this RPC method implemented yet, but it will be implemented in the upcoming release.

Gas estimation on mainnet does not work. Temporary solution is to estimate gas on testnet and set gasLimit value for transactions that needs to be broadcasted to mainnet.

Use web bridge zksync, transfer 0.001 ETH，The ETH cost is 0.00155528 ETH

But using the Python SDK, I found that the same amount of transfer The ETH cost is 0.006 ETH

It can be said that there is a big difference, so to solve this problem, you need to pass the gas_limit parameter

eth_provider.deposit(token=Token.create_eth(),
                                         to=to,
                                         amount=Web3.to_wei(amount, 'ether'),
                                         l2_gas_limit=1123680,
                                         gas_limit=200000,
                                         gas_price=int(eth_web3.eth.gas_price * 1.2))

At the same time, I found another problem, it may be a bug, the gas_limit should be l2_gas_limit, Why？ it can be found through the contract， the base cost is : l2GasPrice * _l2GasLimit

    /// @notice Estimates the cost in Ether of requesting execution of an L2 transaction from L1
    /// @return The estimated L2 gas for the transaction to be paid
    function l2TransactionBaseCost(
        uint256 _gasPrice,
        uint256 _l2GasLimit,
        uint256 _l2GasPerPubdataByteLimit
    ) public pure returns (uint256) {
        uint256 l2GasPrice = _deriveL2GasPrice(_gasPrice, _l2GasPerPubdataByteLimit);
        return l2GasPrice * _l2GasLimit;
    }

/zksync2/provider/eth_provider.py

        base_cost = self.get_base_cost(gas_price=gas_price,
                                       gas_per_pubdata_byte=gas_per_pubdata_byte,
                                       gas_limit=gas_limit)

Any news, or plan to share with us? :)
