The DeFi swap experience has improved significantly over the years. Aggregators now play a key role in that progress by scanning hundreds of liquidity sources, comparing routes, and helping users find better prices across DEXs. But there is still one major gap in most swap experiences: the price you see at quote time is not always the price you get at execution time.
A route may look optimal when the quote is generated, but that can change before the transaction executes. Liquidity can shift, another trader can move the pool, a PropAMM – professional market maker who can dynamically adjust their pricing, can widen its spread or a volatile token can move within seconds. When that happens, the pool that looked best at quoting may no longer deliver the best output at execution.
This gap matters and Smart Settlement is built to close that gap.
KyberSwap’s Smart Settlement represents a major step forward for EVM onchain routing, bringing real-time execution intelligence into the swap process. It introduces a new direction for EVM swap execution, where routing is not only optimized before submission but can also become smarter at the moment the trade settles.
The Problem with Standard Aggregation
Standard DEX aggregators determine the optimal swap route at quote time – before a transaction is submitted. While this works well under normal conditions, it leaves trades exposed to execution-time risks: liquidity shifts, front-running, and PropAMM operators who quote tight spreads to attract order flow before widening them at execution.
When this happens, the original route may become stale. The user may receive fewer tokens than expected or the transaction may fail if the received amount drops below the slippage limit. This creates a difficult trade-off for users. Set slippage too low and the swap may revert. Set slippage too high and the trade becomes more exposed to poor execution or MEV.
Smart Settlement gives users a better path. Instead of forcing the transaction to always follow the original pool selection, it allows the swap to adapt at execution time.
Smart Settlement: A New Layer of Swap Execution Intelligence
Smart Settlement is an onchain execution layer for KyberSwap Aggregator. KyberSwap’s Dynamic Trade Routing already finds efficient swap routes across liquidity sources at quote time. Smart Settlement extends this by adding real-time pool comparison at the moment of execution.
When Smart Settlement is active, KyberSwap can prepare multiple candidate pools for a swap hop. During execution, the smart contract compares those candidates onchain and selects the pool that gives the highest token output. This happens atomically within the same transaction, with no additional steps required from the user.
You still swap the same way. The difference is that the transaction is now more adaptive. It can react when the originally selected pool no longer offers the best outcome.
The Result: Better Swap Output With Lower Slippage
A better quote is useful, but a better execution outcome is what actually matters. The best swap experience is not only about showing a good number before the trade. It is about helping users receive the best possible output when the transaction settles.
More Tokens Received
At execution time, Smart Settlement compares candidate pools and selects the one that maximizes token output. If the originally selected pool remains the best option, the swap continues through it. If another candidate pool becomes better by the time the transaction executes, Smart Settlement can switch to that pool instead. This helps users receive more tokens compared to a static execution path.
Minimized Slippage
Slippage often happens because the market changes between quote and execution. Smart Settlement reduces this risk by checking pool conditions closer to the settlement moment. This helps narrow the gap between the quoted amount and the actual amount received.
Protection Against PropAMM Spoofing
PropAMMs can provide strong liquidity and competitive quotes, but they can also adjust pricing dynamically. In some cases, a pool may show a tight quote to attract order flow and then widen spreads before execution. Smart Settlement helps protect users from this behavior by comparing actual pool output onchain. If the quoted pool no longer offers the best execution, Smart Settlement can route through a better candidate instead.
Better Execution for Volatile and Meme Pairs
Volatile tokens and meme coins can move quickly. A route that looked good seconds ago may become worse once another trade hits the same pool. Smart Settlement is especially useful in these conditions because it can detect when a pool has become worse and choose an alternative with better output. For users trading fast-moving assets, this means fewer surprises between quote and settlement.
Resilience Against MEV and Sandwich Risk
Even when the originally selected pool is sandwiched or front-run within the same block, Smart Settlement can detect the worsened rate and switch to a better pool. This provides an additional layer of resilience on top of your existing slippage protection.
Protection Against JIT Liquidity Removal
Some liquidity can appear deep at quote time but disappear before execution. This can happen when liquidity providers add temporary liquidity to appear attractive to aggregators, capture order flow, or liquidity mining incentives, and then remove it before execution. When this happens, the pool may become shallower than expected and deliver worse output. Smart Settlement helps address this by checking candidate pools during execution. If liquidity has been removed and the pool output has worsened, Smart Settlement can choose another pool with sufficient depth.
Toward a Smarter Future for EVM Trading
EVM onchain routing is entering a new phase. The next frontier is not only about finding the best quote. It is about making sure the final execution outcome stays as strong as possible when the transaction settles onchain. Smart Settlement brings that intelligence to KyberSwap Aggregator.
As one of the first innovations in EVM onchain routing, Smart Settlement marks an important step toward smarter and more adaptive DeFi execution. It points to the next era of onchain routing, where swaps become more dynamic, execution-aware, and built to deliver better outcomes in real market conditions. Smart Settlement is now available on all supported EVM chains.
No additional protocol fee, no extra step needed.
You’ve got the best quote, now you get the best execution.
