Aggregator research
DEX Aggregators with Gasless Swap or Order Modes
Compare documented gasless swap and order capabilities, supported product modes, network scope and eligibility conditions across active aggregators.
Gasless describes who handles gas, not a universal zero-cost trade
Gasless execution can mean that a resolver, market maker or integration pays network costs, or that costs are recovered through the trade. Some platforms document only gasless limit-order submission, not ordinary swaps. The listings below require a sourced and dated capability record; each row preserves the exact product scope and conditions.
Documented platforms
6 of 6 matching listings ยท alphabetical, not a performance ranking
| Platform | Status and product scope | Sources and review date |
|---|---|---|
| 1inch | Conditional Fusion execution on supported EVM networks; not Classic mode. Initial approvals may need gas. Solana Fusion requires SOL to publish the intent. Resolver execution costs can be reflected in output. Documented networks: Ethereum, BNB Chain, Base, Arbitrum. | Checked |
| CoW Swap | Conditional Signed ERC-20 orders settled by CoW Protocol solvers. Settlement costs are paid through the sell token. Token approvals and native-token order submission can still require an on-chain transaction. Documented networks: Ethereum, Gnosis, Arbitrum, Base, Polygon. | Checked |
| Jupiter | Conditional Eligible Swap V2 orders, JupiterZ quotes or an integrator-funded payer. Automatic sponsorship depends on SOL balance and trade size, and can reduce output through higher fees. Account rent and referral settings change who pays. Documented networks: Solana. | Checked |
| KyberSwap | Conditional Maker creation and off-chain cancellation of KyberSwap limit orders. This does not label ordinary aggregator swaps gasless. Token approval, taker settlement and hard cancellation are separate on-chain actions. Documented networks: Ethereum, BNB Chain, Base, Arbitrum, Polygon. | Checked |
| Matcha | Conditional Matcha Auto for supported trading pairs and networks. Auto handles gas for the supported swap flow. Standard swaps and unsupported pairs must be assessed separately. Documented networks: not specified; do not assume all networks. | Checked |
| OpenOcean | Conditional Gasless API on networks explicitly marked supported in the current matrix. These networks are a checked subset; gasless coverage is narrower than normal Swap API coverage. Ethereum is not marked enabled in the current matrix. Documented networks: BNB Chain, Base, Polygon, Arbitrum. | Checked |
Only active listings with a sourced, dated capability claim appear. Conditional support may apply to one product mode or a limited set of networks. Missing platforms may simply be undocumented.
Read the conditions behind the gasless label
Confirm the product mode and network
1inch documents gasless execution for EVM Fusion flows, while its Solana Fusion guide requires SOL to publish an intent. A platform-level capability should not be read as a promise that every trading screen, network, order type or approval is gasless.
Check eligibility and the actual output
Jupiter documents automatic sponsorship, market-maker fee payment and an integrator payer as separate paths. Automatic sponsorship can recover costs from output tokens. Eligibility and required account costs should be checked for the specific trade.
Use the review date and network scope
Available means the cited product offers the capability within its stated scope; Conditional makes an eligibility or mode restriction explicit. A missing platform may be undocumented, not unsupported. Follow the source links before making a product choice.
