# Getting gas on re.al
The re.al L2 chain dedicated to RWAs is a blockchain on which you will be able to read and write transactions. However, as with any other blockchain, writing will require you to pay a tiny amount of gas. The gas used on re.al is reETH, but let's see what is reETH, and how you can get some on re.al.
## What is reETH
The gas token of re.al is reETH, a wrapper for ETH LSTs (**L**iquid **S**taked **T**oken) on Ethereum Mainnet. Currently, only LIDO stETH is used to back reETH. The stETH tokens are stored in a vault on Ethereum, and for each stETH locked in the vault, an equivalent number of reETH is minted.
As stETH is accruing staking rewards, the rewards are distributed in the form of rebases. The reETH gas token is receiving the same rebases as stETH does, however instead of getting a balance rebase (the number of stETH increases over time), reETH receives a value rebase (with time, 1 reETH can be exchanged for more and more ETH).
When you use the native bridge of re.al to send reETH to re.al, the following steps happen
* your ETH is stored in the re.al vault in the form of stETH
* the same amount of reETH is minted
* the reETH is sent to re.al via the Arbitrum Orbit native bridge
* the reETH is added to your wallet on re.al
If you need more details on reETH, you can read [the official documentation about reETH](https://docs.re.al/get-started/reeth-native-token).
## How to bridge reETH to re.al
You can find the [official native bridge on the re.al app](https://www.re.al/app/bridge). It will allow you to send tokens between different chains to re.al, or from re.al to other chains. Here, we want to send ETH from Ethereum Mainnet to re.al, so you will have to pick the right token and the right chains in the interface, as shown below:
Pay attention to keep enough gas on Ethereum to actually pay for the bridging transactions. The process includes 3 or 4 different steps
* Approving minting reETH (only required for the first time you bridge ETH to re.al)
* Minting reETH
* Approving the bridging transaction
* Executing the bridging transaction
You will have to wait for about 15 minutes for the transaction to settle on re.al, after which you will be able to make transactions on re.al.

Since re.al is a L2 blockchain, gas fees are a lot cheaper than on Ethereum Mainnet. The average transaction fee, according to the block explorer, is 0.000030885746336761 reETH, which corresponds to $0.11 with the current price of reETH as of writing this page.
It is thus recommended to send between $5 and $10 to make sure you have enough gas to perform a few transactions.
{% endhint %}
You can list all bridge operations you did by clicking the transactions button at the top of the bridge page of re.al. You can switch between the pending transactions and settled transactions to get details of your recorded actions.
## Getting gas using gas.zip
It may be expensive to use Ethereum Mainnet and the native bridge to send reETH to re.al, especially if you send a very small amount of ETH to the new L2. If your goal is to send just a few dollars of ETH to be able to perform your first few transactions on re.al, you can instead use the [gas.zip gas station](https://www.gas.zip/) from LayerZero. This small tool will grab the gas fee from the chain you send funds and transfer reETH to your wallet on re.al.
As an example, if you want to send gas from Polygon to re.al, you should
* indicate Polygon as the source chain
* pick the amount of reETH you want to receive on re.al
* select re.al as the destination chain
* indicate your wallet address as the EVM address to which reETH will be sent
{% hint style="warning" %}
You obviously need to have the equivalent amount of gas in your wallet for the operation to succeed. For this example, you would need $5 of MATIC if you are on Polygon. You can use gas.zip from Base and send reETH to re.al by paying with ETH on Base.
{% endhint %}
The amount of time taken to complete the gas refill depends on the source chain, but you can expect the transaction to complete below 30 minutes. I used this tool
* from Polygon to re.al: takes \~25min
* from Base to re.al: takes \~3min
Please note that gas.zip is a gas station to send small amounts of gas tokens to be able to perform transactions, it's not meant to bridge big amounts of reETH on re.al. If you want to do that, your best option remains the native bridge.
