Decentralized exchanges (DEXs) have revolutionized the way users trade digital assets by offering non-custodial, permissionless trading environments. Among the most popular platforms, PancakeSwap stands out for its advanced routing mechanisms and flexible fee structures—especially within its V3 trading system. This guide dives into how transaction fees are calculated, how routing works, and how traders can customize their swap paths to optimize execution.
Whether you're a beginner exploring automated market makers (AMMs) or an experienced trader fine-tuning execution strategies, understanding these mechanics is essential for minimizing costs and maximizing returns.

How Smart Routing Works in V3
The V3 version of PancakeSwap introduces a sophisticated smart routing engine designed to find the best possible price for every trade. By default, the system aggregates liquidity from multiple sources across different protocols and layers:
- V3 Pools
- V2 Pools
- Stableswap Pools (on BNB Chain)
- AMM Liquidity
- Market Maker (MM) Liquidity (on BNB Chain and Ethereum)
This multi-source approach ensures that trades are executed at optimal rates, even for large orders or low-liquidity token pairs. The smart router evaluates all available paths in real time, splitting trades when beneficial and selecting the most cost-effective route.
It’s important to note that AMM pools and market maker liquidity operate independently. A trade executed through a market maker will not pass through any AMM pool, which helps maintain pricing integrity and reduce latency.
Viewing Transaction Fees and Execution Details
Before confirming any swap, users can review detailed cost breakdowns directly in the interface.
Check Your Fee Rate and Total Cost
Look for the "Transaction Fee" section in the swap confirmation window. This displays:
- The exact fee amount in the output token
- The percentage rate applied based on the selected pools
These fees are determined by the underlying pool’s structure—V3 pools, for example, use concentrated liquidity models where fees vary by tier (e.g., 0.01%, 0.05%, 0.3%).
Analyze the Swap Path
Beneath the main trading panel, you’ll find the "Route" or "Router Path" indicator. Clicking the magnifying glass icon reveals the full execution path, including:
- Which pools were used
- Whether the trade was split across multiple routes
- If multi-hop swaps were involved
This transparency empowers traders to verify whether their trade took an efficient path and understand how fees were accumulated.
Customizing Liquidity Sources
For advanced users, PancakeSwap offers full control over which liquidity sources are considered during routing.
Accessing Custom Routing Settings
You can open the Custom Routing menu by:
- Clicking “Custom Route” at the bottom of the route preview
- Opening the settings (gear) icon in the swap interface, then selecting “Custom Route”
Once inside, you’ll see a list of available liquidity sources—all enabled by default.
Available Liquidity Sources Include:
- V3 Pools
- V2 Pools
- Stableswap Pools
- AMM Liquidity
- Market Maker Liquidity
Disabling any of these restricts the router from using them, potentially affecting execution quality. For instance, disabling market makers may lead to higher slippage on large trades, especially on Ethereum where gas costs are high.
To revert changes, simply click the "Reset" button in the top-right corner of the settings panel. This restores all defaults instantly.

Adjusting Route Preferences: Multi-Hop & Path Splitting
Below the liquidity source selector, users can fine-tune two critical routing behaviors: multi-hop swapping and path splitting.
Enable or Disable Multi-Hop Swaps
A multi-hop swap routes your trade through more than one pool—for example, swapping Token A → BNB → Token B instead of seeking a direct A→B pair.
Benefits:
- Access to deeper liquidity
- Better prices when direct pools lack depth
Risks of Disabling:
- Higher slippage
- Failed trades if no direct pair exists
While disabling multi-hop may feel safer due to fewer intermediary steps, it often leads to suboptimal outcomes.
Control Path Splitting Behavior
Path splitting divides your order across several routes to minimize impact on any single pool.
For example, a $10,000 USDT → CAKE trade might be split as:
- $6,000 via V3 Pool (USDT/BNB + BNB/CAKE)
- $4,000 via Market Maker Direct Quote
This reduces price impact and improves overall fill quality.
Disabling path splitting forces the entire amount through one route, increasing slippage risk—especially for large trades.
Handling Trade Execution Warnings
If your custom routing settings prevent a trade from being executed, PancakeSwap displays a clear warning message.
The alert typically includes two options:
- Check Your Settings: Opens the Custom Routing panel so you can adjust preferences
- Reset to Default: Instantly re-enables all liquidity sources and features
This safeguard helps avoid failed transactions while giving users room to experiment with configurations.
Frequently Asked Questions (FAQ)
What is smart routing in decentralized exchanges?
Smart routing is an algorithmic system that analyzes multiple liquidity sources to find the best price for a trade. It considers factors like pool depth, fees, and slippage to determine whether to split trades, use multi-hop paths, or route through market makers.
How are transaction fees calculated on PancakeSwap V3?
Fees depend on the pool type and fee tier used in the swap path. V3 pools offer customizable fee tiers (e.g., 0.01% for stablecoins, 1% for volatile tokens). The total fee is a weighted average if multiple pools are involved.
Can I disable market maker liquidity?
Yes. In the Custom Routing settings, you can disable MM liquidity. However, doing so may result in worse prices or failed trades, especially on Ethereum or for large orders.
Does splitting my trade increase gas costs?
No—on PancakeSwap, even split or multi-hop trades are executed in a single transaction. You pay one gas fee regardless of complexity.
Why did my trade fail even with sufficient balance?
Custom routing settings—such as disabling multi-hop or specific pool types—can limit available paths. If no viable route exists under your constraints, the trade fails. Resetting to default often resolves this.
Is there a benefit to using only V3 pools?
V3 pools offer greater capital efficiency due to concentrated liquidity. However, relying solely on them may reduce execution quality if they lack sufficient depth for your trade size.
