This guide is a practical companion for swapping tokens with PawSwap. You’ll learn how routing works, how to tune slippage and gas, and how to use advanced features like limit orders and DCA, while protecting yourself from common pitfalls and MEV exposure.
Swap Methods with PawSwap (and Alternatives)
PawSwap acts as an interface/routing layer across multiple liquidity sources. Depending on your goals (speed, control, order size), different methods may fit better.
Comparing Swap Methods
| Method | Best For | Key Features | Considerations |
|---|---|---|---|
| PawSwap Aggregator (UI) | Best execution, broad liquidity | Route simulation, split routes, slippage controls, MEV-aware flows, verified lists | Results depend on network liquidity; always verify token contracts |
| Single DEX / AMM | Simple flows, specific pools | Direct pool interaction, predictable pool fee | May miss better routes; larger price impact on thin pools |
| Limit Orders (via PawSwap if supported) | Target price execution | Off-chain monitoring; on-chain settlement at trigger | No fill guarantee; consider partial fills & expiry |
| DCA (via PawSwap if supported) | Reduce timing risk | Automated periodic swaps, budget control | Fees/gas across legs; ensure funding and schedule |
Understanding Fees on PawSwap
On EVM networks, you pay gas (in the chain’s native token) plus any AMM pool fees embedded in the route. Effective cost also includes price impact on low-liquidity pairs and any optional interface/integrator fees.
Typical Fee Components
| Fee Type | Typical Range | Notes |
|---|---|---|
| Gas (EVM) | Varies by network load | Paid in native token (e.g., ETH). Consider off-peak times or priority settings. |
| Pool / Liquidity Fee | ~0.05%–0.3%+ | Set by the AMM/pool; varies by route and pair. |
| Price Impact | Route-dependent | Higher for illiquid tokens or large size; mitigated by route splits/limit orders. |
| Optional Interface Fee | 0%–X% | Shown transparently in reputable UIs; verify before signing. |
Safety & Best Practices
DeFi is powerful but unforgiving. Use these practices to stay safe.
Practical Protections
- Verify token contracts: Use reputable lists or the project’s official site. Beware ticker clones.
- Slippage discipline: Tight for liquid majors (e.g., 0.1–0.5%), looser for thin tokens. Consider partial fills.
- MEV-aware flow: Prefer private RPC / “send to builder” options when available; avoid leaking transactions to public mempools for large swaps.
- Allowance hygiene: Grant minimal token approvals; periodically revoke old allowances.
- Test first: Try a small swap before executing big size.
- Phishing defense: Bookmark official URLs; never sign unknown or opaque transactions.
Compliance & Risks
Swaps carry market risk (volatility, slippage) and smart-contract risk (pool/router issues). Keep transaction records per your jurisdiction’s rules. Store seed phrases offline and consider hardware wallets.

Frequently Asked Questions (FAQ)
What makes PawSwap different from using a single DEX?
PawSwap aggregates routes across multiple pools/DEXs, often splitting orders to reduce price impact and improve effective price versus swapping in one venue.
How do I set slippage correctly?
Use tight slippage (e.g., 0.1–0.5%) for highly liquid pairs and wider for illiquid ones. If price moves beyond your tolerance, the transaction won’t execute.
How can I reduce MEV risk?
Use private RPC or builder relays when available, avoid mempool leakage on large trades, and keep slippage tight. Consider splitting size or using limit orders.
Which wallets work best?
MetaMask and Rabby are common choices on EVM networks; combine with a hardware wallet for stronger key security. Keep native tokens for gas.
Does PawSwap support limit orders and DCA?
If supported in the current UI, limit orders target a specific price and execute upon reaching it, while DCA schedules periodic swaps to reduce timing risk.
Why did my output differ from the initial quote?
On-chain states change quickly. Factors include price impact, pool fees, and route refresh. Proper slippage and timely execution minimize discrepancies.
Do I need KYC?
Interfaces like PawSwap typically connect your wallet directly to on-chain liquidity. However, your local laws may impose reporting obligations—keep records.
How large can I swap without heavy slippage?
It depends on route liquidity. For larger size, try splitting orders, using limit orders, or scheduling DCA to reduce impact.
How do I verify I’m buying the correct token?
Match contract addresses from official project pages or reputable sources (e.g., Etherscan). Be wary of ticker look-alikes.
My transaction failed — what now?
Common causes: insufficient gas, too-tight slippage, stale route, or allowance issues. Add native gas token, widen slippage slightly, refresh the route, re-approve if needed, and retry with a small test.
