Frequently asked questions

How does GasHawk work?

GasHawk acts as a buffer for transactions on the Ethereum network. Instead of directly sending a transaction to the network, GasHawk users send their signed transaction to the GasHawk RPC proxy using MetaMask, the SDK, or the REST API. GasHawk determines when to submit the transaction based on historical data, knowledge of the effects of EIP-1559, and other relevant data to optimize gas fee savings. GasHawk is a trusted platform as it only receives signed transactions from users and cannot modify them without the user's private key. GasHawk offers a dashboard with gas price statistics and allows users to set a desired waiting time, while still achieving savings on gas fees.

How does GasHawk know when to submit a transaction to save on gas fees?

GasHawk knows when to submit a transaction to save on gas fees by using historical data, knowledge of the effects of EIP-1559, and other relevant data for its submission strategy. It acts as a buffer for transactions and forwards them to the Ethereum network when gas prices are low. GasHawk receives signed transactions from its users and cannot change any part of them without the user having to sign them again using their private key. GasHawk also offers an option to automatically send transactions through Flashbots Protect for users whose transactions are susceptible to frontrunning or other MEV.

Why can I trust GasHawk?

GasHawk uses historical data, knowledge of the effects of EIP-1559, and other data for its submission strategy. GasHawk only receives signed transactions from its users, which cannot be changed without the user's private key. GasHawk also offers an option to use Flashbots Protect for transactions susceptible to MEV. GasHawk acts as a buffer for transactions, forwarding them to the Ethereum network when gas prices are low. Users can set a deadline for their transactions and enjoy savings and more predictable waiting times with GasHawk.

Can I use GasHawk if my transactions are susceptible to MEV?

Yes, you can use GasHawk if your transactions are susceptible to MEV. GasHawk offers an option in the user settings to automatically send all transactions through Flashbots Protect. This keeps your transaction private until it is picked up by a Flashbots-enabled validator. However, it is recommended to set a higher priority fee (3-5 Gwei) to incentivize the validators and ensure a shorter time between GasHawk's decision to submit the transaction and its inclusion.

Why would I need GasHawk if I can simply set a low value for maxBaseFeePerGas?

GasHawk offers an option in the user settings to automatically send all transactions through Flashbots Protect, which keeps your transactions private until they are picked up by a Flashbots-enabled validator. While setting a low value for maxBaseFeePerGas can help save on gas fees, GasHawk provides additional benefits. GasHawk helps estimate future base fee values and sets a suitable maxBaseFeePerGas to increase the chances of your transaction being included in a block. It also offers more predictable waiting times and potential savings compared to manually setting a low value for maxBaseFeePerGas.

Can I set a deadline until when a transaction should be ultimately sent?

GasHawk is a tool that helps optimize gas fees for Ethereum transactions. It allows users to set a deadline for when a transaction should be ultimately sent. Each GasHawk account has a default deadline setting, and users can also edit the deadline for each transaction individually. If the deadline passes without GasHawk finding a cheap price, GasHawk will still send the transaction to the Ethereum network, and the normal process will take place where the maxBaseFeePerGas setting of the transaction will protect against very high gas prices.

What happens when the deadline passes without GasHawk finding a cheap price?

GasHawk works by timing transactions smartly to save on gas fees. It predicts the base fee and selects a good gas price to ensure savings. GasHawk knows when to submit a transaction by using a deadline setting. Each GasHawk account has a default deadline, and GasHawk will look for the best gas price within the specified time frame. If the deadline passes without GasHawk finding a cheap price, GasHawk will send the transaction to the Ethereum network, and the normal process will take place with the maxBaseFeePerGas setting protecting against high gas prices. Trust in GasHawk is based on its ability to find low prices and its track record. GasHawk can be used even if transactions are susceptible to MEV (Miner Extractable Value). While setting a low value for maxBaseFeePerGas is an option, GasHawk offers additional benefits such as more predictable waiting times and potentially lower prices than manually selected.

How should I set the priority fee of my transaction?

We recommend setting the priority fee to 3 Gwei per gas, which is slightly more than the current market average. This helps to ensure that when GasHawk finds a low price, your TX will be included into one of the very next blocks.
