Is it possible to send a transaction without requiring users to pay gas?
We can do better. Enter meta-transactions. This is a fancy name for a simple idea: a third-party (called a relayer) can send another user’s transactions and pay themselves for the gas cost. In this way, users can interact directly with smart contracts without needing to have a wallet or own Ether.
Can a smart contract pay gas?
People who want to interact with the smart contract must sign the function parameters with their account’s private key and send it to the smart contract owner (via any communication channel). The owner then submits the parameters along with the signature to the blockchain, paying for gas.

Who pays for gas ethereum?

What is a meta transaction?
What are meta-transactions? A meta transaction is a regular Ethereum transaction which contains another transaction, the actual transaction. The actual transaction is signed by a user and then sent to an operator or something similar, no gas and blockchain interaction required.
What are gas fees for Ethereum?
Gas refers to the fee required to successfully conduct a transaction on Ethereum. Gas fees are paid in Ethereum’s native currency, ether (ETH). Gas prices are denoted in gwei, which itself is a denomination of ETH – each gwei is equal to 0.000000001 ETH (10-9 ETH).
What is gas fee in Ethereum?
Gas fees are payments made by users to compensate for the computing energy required to process and validate transactions on the Ethereum blockchain. As such, the price of gas fluctuates (priced in ETH) with supply and demand for processing power.

| 4 | Mooniswap | $64.32 |
What happens if gas fee is too low?
If a gas price is set too low, the transaction could be missed, ignored, or the wallet could become stuck, freezing transactions from that wallet. A wallet will remain stuck until the transaction is resolved. In the event of a stuck wallet, a user will have to issue a Speed Up or Cancel transaction.
Do you need gas to send an Ethereum transaction?
Anyone who sends an Ethereum transaction needs to have Ether to pay for its gas fees. This forces new users to purchase Ether (which can be a daunting task) before they can start using a dapp. This is a major hurdle in user onboarding.
How are transactions relayed on the GSN network?
The GSN is composed of a central RelayHub contract that coordinates all relayed transactions, as well as multiple decentralized relayers. The relayers are processes that receive requests to relay a transaction via an HTTP interface and send them to the network via the RelayHub.
How does the gas station Network ( GSN ) work?
The Gas Station Network (GSN) is a decentralized network of relayers. It allows you to build dapps where you pay for your users transactions, so they do not need to hold Ether to pay for gas, easing their onboarding process.
