TIP 1: Set up gas price alerts
------------------------------

The best way to save your eth is to perform transactions when the gas price is low. You can see the current gas price on [etherscan.com/gastracker](http://etherscan.com/gastracker), but it's not practical to watch the gas all day,

Instead, set up alert [this](https://cryptocurrencyalerting.com/eth-gas-tracker.html) is a great website, that lets you set up email alerts. Track the ETH gas price automatically, and get notified when it's a smart time to send a transaction. When gas dips to your price, you'll get an email alert.

TIP 2: Replace transactions instead of cancelling them
------------------------------------------------------

Instead of cancelling your transaction on Metamask, you can actually replace it on the blockchain - the idea here is to replace the transaction with one that uses less gas, and is therefore cheaper to execute.

To do this, first enable the "Custom transaction nonce" in your Metamask under advanced settings.

Then, find the nonce of your pending transaction on the transaction page in [Etherscan](https://etherscan.io/)

Then, transfer yourself 0ETH on Metamask and you'll get charged gas fee for the transaction. Before you submit, enter the nonce of your pending transaction in the Custom nonce field.

If your pending transaction wasn't submitted, it will be dropped for this transaction, saving you ETH. Why? Because transferring ETH is cheaper than interacting with a smart contract.

TIP 3: Swap multiple tokens in a single transaction
---------------------------------------------------

Batch swapping saves you from the hurdle of making individual transactions for each token swap. And also, instead of paying gas for individual transactions, you pay fee once. Batch swapping tokens through DZap save upto **42% on gas fees.** Yes that’s true! upto 42%.
