Top 10 des DEX sans frais de gaz
Blockchain transactions typically require users to pay gas fees — which can add up quickly on networks with high demand. Gasless DEXs aim to remove this friction by enabling users to interact with decentralized markets without directly bearing gas costs at the time of transaction.
In this guide, we highlight the Top Gasless DEXs of 2026, focusing on platforms that combine fee automation, strong liquidity, intuitive interfaces, and broad token support while ensuring a userfriendly experience in decentralized trading.
Points clés à retenir
Gasless DEXs reduce user friction by covering or abstracting gas costs.
These platforms often rely on meta-transactions, sponsor tokens, or rebate systems.
Gasless trading helps onboard new users and lowers barriers to entry in DeFi.
Why Gasless DEXs Matter
High gas fees can discourage participation, especially for smaller traders or newcomers to DeFi. Gasless DEXs address this challenge by:
Lowering cost barriers to swaps and trades
Improving accessibility for users unfamiliar with native fee models
Streamlining UX, making DeFi feel more like centralized trading
Supporting beginner traders with near-free interactions
By abstracting gas, users can focus on trading strategy rather than transaction costs.
How Gasless DEXs Work
Meta-Transactions
Users sign a transaction that is submitted by a relayer or service that pays gas on the user’s behalf.
Sponsored Fees
Some protocols cover gas costs using platform tokens or rewards, reimbursing users for network costs.
Bundled Execution
Certain aggregators bundle multiple operations together, reducing overall gas costs per action.
Post-Paid Settlement
Some systems bill gas fees in protocol-native tokens rather than requiring native chain gas at execution.

Evaluating Gasless DEXs
Liquidity & Slippage
Even with gas abstraction, users need deep liquidity to ensure tight spreads and efficient execution.
Security & Trust
Relayer and sponsorship models introduce additional trust assumptions — choose platforms with robust audits and transparent mechanisms.
Supported Tokens
Broad token availability increases usability and trading flexibility.
UX & Onboarding
Simple interfaces and clear instructions reduce confusion for gasless trading workflows.
Risques et limites
Relayer Risk
Gasless systems often depend on third-party relayers that front fees, adding systemic risk if a relayer fails.
Hidden Costs
Some platforms subsidize gas but may offset costs through fees embedded in prices or protocols.
Network Dependence
Gasless models may not fully eliminate costs on all chains; users may still be exposed indirectly.
Résumé
Gasless DEXs modernize decentralized trading by lowering the barrier to entry and making swaps more accessible for everyday users. The Top Gasless DEXs of 2026 balance cost efficiency, liquidity, and usability — allowing users to interact with DeFi without worrying about direct gas costs.
Foire aux questions
What is a gasless DEX?
A gasless DEX is a decentralized exchange that enables traders to swap tokens without paying blockchain gas fees directly, using mechanisms like sponsored transactions, relayers, or meta-transactions.
How do gasless transactions work?
Users sign a trade request that is then submitted to the blockchain by a relayer or sponsor, who covers the gas cost in exchange for a separate fee model.
Are gasless DEXs safe?
Safety depends on relayer trust models, smart contract security, and protocol design. Always check audit history and transparency.
Do I still pay fees on gasless DEXs?
Gasless doesn’t always mean free — platforms may recoup costs through trade fees, token economics, or service charges.
Are gasless DEXs available on all blockchains?
Gasless models are more common on chains with native fee abstractions or relayer infrastructure, though implementations vary.
