**A gasless transaction,** also called a meta transaction, is a [blockchain](https://iq.wiki/wiki/blockchain) transaction in which the user does not pay the network fee, known as the [gas fee](https://iq.wiki/wiki/gas), from their own balance. Instead, a third party—typically a [smart contract](https://iq.wiki/wiki/smart-contract) called a paymaster or a relayer service—sponsors the fee or accepts payment in a different token such as a [stablecoin](https://iq.wiki/wiki/stablecoin).[\[1\]](#cite-id-jni77owt7i) 

Gas fees are normally paid in a network's native token, such as [ETH](https://iq.wiki/wiki/ether-eth) on [Ethereum](https://iq.wiki/wiki/ethereum), and removing that requirement allows users to appear to transact without any direct cost.[\[2\]](#cite-id-lne4rvibgz)​[\[3\]](#cite-id-tl4glu5qa7) The mechanism does not mean the network operates for free; someone always pays the fee, and the significant difference is who pays and in what currency.[\[1\]](#cite-id-jni77owt7i)​

The primary purpose of gasless transactions is to lower the barrier to entry for new users. Sponsored fees address the cold-start problem, in which a newcomer holds tokens but cannot move them because they lack the chain's native coin for gas. By removing the need to acquire native tokens upfront, the approach simplifies onboarding and abstracts away concerns about wallet balances and fluctuating gas prices. [\[1\]](#cite-id-jni77owt7i) [\[2\]](#cite-id-lne4rvibgz)​

## How It Works

Gasless transactions are built on a meta-transaction architecture, a pattern in which the user authorizes an action without directly submitting or paying for it on-chain.[\[2\]](#cite-id-lne4rvibgz) 

The user signs the action they want—for example a transfer, swap, or mint—using their private key off-chain, but does not sign the fee payment.[\[1\]](#cite-id-jni77owt7i)​[\[2\]](#cite-id-lne4rvibgz) Because the signing happens off-chain, the user does not need to hold any [cryptocurrency](https://iq.wiki/wiki/cryptocurrency) for [gas](https://iq.wiki/wiki/gas) at the moment of authorization.

The signed message is then forwarded to a relayer, which can be an automated [smart contract](https://iq.wiki/wiki/smart-contract) or a manual user.[\[3\]](#cite-id-tl4glu5qa7) The relayer, or a paymaster contract, attaches the gas payment and submits the transaction to the network.[\[1\]](#cite-id-jni77owt7i) The sponsor either absorbs the cost—as a promotion or an application expense—or charges the user in another token the user already holds.[\[1\]](#cite-id-jni77owt7i) 

Finally, the smart contract verifies the user's signature and the network processes the transaction through its usual validation process, executing the intended action on the user's behalf and finalizing it; fees are paid, but not directly by the user in the native coin.[\[2\]](#cite-id-lne4rvibgz)​[\[3\]](#cite-id-tl4glu5qa7)​

The model therefore depends on a funding source. In one common design, a third-party gas fee pool exists into which owners deposit a certain amount of crypto; the pool balance is deducted after every transaction, so users appear to transact at no cost.[\[3\]](#cite-id-tl4glu5qa7) 

The discussion of gasless transactions generally applies to public [blockchains](https://iq.wiki/wiki/blockchain), defined as blockchains that require no permission to create an address, in contrast to private blockchains that can only be joined with prior permission.[\[3\]](#cite-id-tl4glu5qa7) Separately, [Layer-2](https://iq.wiki/wiki/layer-2) networks, which operate on top of a base blockchain, use a different method to reduce gas fees rather than the meta-transaction relayer model.[\[3\]](#cite-id-tl4glu5qa7)​

## Standards and Infrastructure

Several technical standards support the meta-transaction pattern on [Ethereum](https://iq.wiki/wiki/ethereum). EIP-712 defines a structured method for hashing and signing typed data and is used to create relayed transactions.[\[2\]](#cite-id-lne4rvibgz)​[\[3\]](#cite-id-tl4glu5qa7) ERC-2771 is a standard for meta-transactions that uses trusted forwarders, [smart contracts](https://iq.wiki/wiki/smart-contract) that relay a signed request to a target contract while preserving the original signer's identity.[\[2\]](#cite-id-lne4rvibgz)​

A number of platform providers supply the infrastructure that makes gasless flows practical. [Biconomy](https://iq.wiki/wiki/biconomy) provides infrastructure for enabling gasless transactions across multiple [blockchains](https://iq.wiki/wiki/blockchain).[\[2\]](#cite-id-lne4rvibgz) 

​[OpenZeppelin](https://iq.wiki/wiki/openzeppelin) Defender offers security and automation tools for smart contracts, including support for meta-transactions, while Gelato automates smart contract executions and supports gasless transaction workflows.[\[2\]](#cite-id-lne4rvibgz) CPAY has also been identified as an organization exploring and implementing gasless transaction solutions.[\[2\]](#cite-id-lne4rvibgz) At the wallet level, [Trust Wallet](https://iq.wiki/wiki/trust-wallet), a self-custody wallet in which users control their own keys, states that whether a fee is sponsored or paid from a user's balance, nothing moves without the user's signature, and that its Security Scanner reviews transactions before the user approves them.[\[1\]](#cite-id-jni77owt7i)​

The idea of removing [gas](https://iq.wiki/wiki/gas) fees has also served a marketing function. According to the Cryptorank article, the concept of the gas fee has been a success for marketing crypto projects that face high competition.[\[3\]](#cite-id-tl4glu5qa7) Torus has been cited as an example of a gasless blockchain; a TorusChain post dated July 19, 2024 promoted the network's speed, scalability, transparency, and introduction of gasless transactions.[\[3\]](#cite-id-tl4glu5qa7)​

## Applications

Gasless transactions have been applied across several areas of [blockchain](https://iq.wiki/wiki/blockchain) activity. In NFT minting, several projects whitelist users and pay the [gas](https://iq.wiki/wiki/gas) on their behalf, allowing users to mint airdropped non-fungible tokens for free.[\[3\]](#cite-id-tl4glu5qa7) In [Web3](https://iq.wiki/wiki/web3) games, players can interact with NFTs or in-game items without needing to hold ETH.[\[2\]](#cite-id-lne4rvibgz) 

​[Decentralized Autonomous Organizations](https://iq.wiki/wiki/dao), or DAOs, use the approach to let members participate in votes and governance without holding native tokens, and [Decentralized Finance](https://iq.wiki/wiki/defi), or DeFi, protocols sponsor gas fees to lower entry barriers for new users.[\[2\]](#cite-id-lne4rvibgz)​

The Cryptorank article also identifies Real [World](https://iq.wiki/wiki/world) Asset (RWA) [tokenization](https://iq.wiki/wiki/tokenization)—the representation of physical or traditional financial assets as blockchain tokens—as a potential area. It argues that gasless transactions might become necessary for RWA tokenization because tokenized assets would be high in value and a project's tokenization fee might include the gas fee by default, relieving users from extra hassle.[\[3\]](#cite-id-tl4glu5qa7) Across these uses, the common rationale is improved user experience: eliminating gas-fee friction and encouraging more frequent interactions, higher retention, and greater participation.[\[2\]](#cite-id-lne4rvibgz) The feature is typically deployed where the benefits to the project outweigh the cost of paying fees on behalf of customers.[\[3\]](#cite-id-tl4glu5qa7)​

## Security and Challenges

Because gasless transactions involve an intermediary submitting a user's signed message, they introduce specific security requirements. Signature verification is needed to ensure transactions are authorized by legitimate users, and trusted relayers are relied upon to avoid malicious activity such as replay attacks, in which a valid transaction is fraudulently repeated, or transaction manipulation.[\[2\]](#cite-id-lne4rvibgz) Protections against spam and front-running—such as rate limiting and transaction validation—are also required.[\[2\]](#cite-id-lne4rvibgz)​

Implementing the model raises several practical challenges. Projects must decide who absorbs [gas](https://iq.wiki/wiki/gas) fees—the platform, sponsor, or relayer—and manage those costs over time.[\[2\]](#cite-id-lne4rvibgz) Lower financial barriers create a risk of abuse, because they can invite spam or excessive transactions, requiring safeguards such as rate limits and identity verification.[\[2\]](#cite-id-lne4rvibgz) The approach also depends on relayer reliability, since relayer downtime or failure can disrupt transaction processing.[\[2\]](#cite-id-lne4rvibgz)​

Users face their own cautions. Nothing is free forever, so users should understand how the sponsor recoups the cost, whether through a markup, a spread, or a marketing budget.[\[1\]](#cite-id-jni77owt7i) A sponsored transaction can still contain a harmful approval, so signatures should be read and approved carefully, and the availability of gasless flows varies by chain, by application, and by token.[\[1\]](#cite-id-jni77owt7i) Despite these constraints, gasless transactions are presented as a tool that removes the barrier of gas fees and enhances the accessibility and user-friendliness of [blockchain](https://iq.wiki/wiki/blockchain) technology, with a continuing role expected in decentralized applications, gaming, and finance.[\[2\]](#cite-id-lne4rvibgz)​
