Gasless DEX Aggregator Modes on Base: Scope and Costs
Compare sourced Base gasless swap and order modes, including approval requirements, settlement costs and the exact product scope of each listing.
Check the Base product mode before comparing costs
This collection requires both listed Base coverage and a sourced gasless feature record that explicitly names Base. A brand’s ordinary swap support is insufficient. The table preserves whether the documented capability concerns a resolver-settled swap, an off-chain limit order or an API integration, because these workflows solve different problems.
Documented platforms
3 of 3 matching listings · 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 |
| 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 |
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.

What a gasless Base mode does and does not cover
Swap settlement and order submission are different
1inch documents resolver execution in Fusion, while KyberSwap documents gasless maker creation for its off-chain limit orders. Creating an order without gas does not establish that ordinary KyberSwap aggregator swaps are gasless. Read the product scope beside each result.
Check approvals and how costs are recovered
1inch notes that first-use contract permissions can require native tokens and that execution costs can reduce the tokens received. CoW Protocol describes settlement fees paid in the sell token. Holding no ETH for a particular settlement step therefore does not imply a fee-free trade or free setup.
Use the matching workflow for the final quote
The manual quote tool on this site requests the integrated provider mode shown in its results. A Classic or ordinary route preview is not a quote for every gasless product listed here. For an actual gasless trade, verify eligibility and the net amount within that provider’s documented Base workflow.
