ParaSwap - Fast, Efficient, Built for L2s
ParaSwap processes ~$500M+ monthly across 40+ liquidity sources with its Augustus protocol. Unlike 1inch's algorithm-first approach, ParaSwap uses a market-maker-driven model where registered market makers provide fast quotes and the protocol picks the best execution. It's particularly strong on L2s where gas is cheap and multi-hop routing is always worth it.
The Augustus Protocol - How It Works
Augustus is ParaSwap's routing engine. Unlike Pathfinder's graph-traversal approach, Augustus works with registered market makers who pre-price liquidity. When you request a swap, Augustus queries all connected market makers and DEXs, then picks the best quote. This gives it sub-100ms quote speeds at the cost of being limited to its market maker network.
User requests a swap: "Swap 5 ETH for USDC, minimum $16,100."
Registered market makers (MMs) submit quotes based on their?? and pricing models.
Augustus also queries Uniswap, SushiSwap, Curve, and other DEXs directly for comparison.
The protocol selects the quote with the best output after fees and price impact.
The swap executes via ParaSwap's TokenTransferProxy contract, which handles the routing.
Delta - Positive Slippage Captured for You
Delta is ParaSwap's most innovative feature. In a standard swap, if the market moves in your favor between quote and execution (you get more tokens than expected), that surplus is typically captured by AMM LPs or MEV bots. Delta redirects positive slippage to the user instead.
Augustus quotes: 1 ETH -> 3,200 USDC (market price at quote time)
Before execution, ETH price moves to 3,220 USDC. Your quoted rate is now better than market!
Instead of extra value going to MEV bots, Delta captures the $20 positive slippage and returns it to you.
You receive 3,220 USDC instead of 3,200 USDC. The $20 positive slippage is yours, not the AMM's.
Save Gas Mode - Efficient Small Trades
On L2s and for smaller trades, the extra gas of multi-hop routing can outweigh the benefits. ParaSwap's Save Gas mode intelligently groups small trades and finds the most gas-efficient execution path.
TVL Comparison - ParaSwap vs 1inch vs CoW
Total Value Locked is a useful proxy for liquidity depth and execution quality. Here's how the major aggregators compare across chains.
Tensor NFT Trading - ParaSwap's Unique Edge
ParaSwap stands apart from every other DEX aggregator by also supporting NFT trading through its integration with Tensor, one of the largest NFT marketplaces on Solana. This gives ParaSwap users a unified interface for both token swaps and NFT trading.
NFT owners list items on Tensor's marketplace at set prices.
ParaSwap queries Tensor's orderbook alongside DEX liquidity.
Best price or best collection-wide fill found across all sources.
Users buy NFTs with the same wallet and interface as token swaps.
Batch Swaps - DeFi Farming Efficiency
ParaSwap's batch swap feature lets you execute multiple swaps in a single transaction. This is particularly valuable for DeFi farmers who need to rebalance across multiple pools in one atomic operation.
When ParaSwap Is the Best Choice
- You're on Arbitrum, Base, or Optimism - ParaSwap's L2 execution is excellent
- You want Delta's positive slippage capture on favorable market moves
- You need batch swap capability for DeFi farming rebalancing
- You want fast quotes without the complexity of 1inch Fusion
- You need Save Gas mode for small-to-medium trades where gas matters
- You want an integrated token + NFT trading experience via Tensor
- You need maximum liquidity coverage (400+ sources) -> use 1inch
- You want full MEV protection via batch auctions -> use CoW Swap
- You're on Ethereum mainnet with a very large trade and need the deepest routing
- You want limit orders with specific price guarantees -> use 1inch
- You need RFQ for institutional-size trades -> use 0x/Matcha

Frequently Asked Questions
How does ParaSwap's Augustus protocol differ from 1inch's Pathfinder?
Pathfinder and Augustus both solve the same routing problem but take different architectural approaches. Pathfinder builds a full graph of all liquidity and evaluates all paths simultaneously. Augustus uses a market-maker-driven model where registered market makers provide liquidity and pricing, and the protocol selects the best quote among them. This gives Augustus very fast quote times (often <100ms) since market makers pre-compute prices, at the cost of being limited to their connected liquidity.
What is ParaSwap's Delta feature?
Delta is ParaSwap's intent-based swap feature that captures positive slippage for users. In a standard swap, if the market moves in your favor between quote and execution (e.g., you get a better price than expected), that surplus typically goes to the AMM or is captured by MEV searchers. Delta redirects that positive slippage back to the user. It's an elegant solution to the MEV problem - instead of fighting MEV, you redirect it.
Does ParaSwap have MEV protection?
ParaSwap's PSG (ParaSwap Security Guild) provides partial MEV protection through direct pool routing. By routing directly to pools without going through the mempool, it avoids the most common sandwich attacks. However, this protection is not as comprehensive as CoW Swap's batch auction model. Delta also helps by capturing slippage before MEV bots can extract it.
How does ParaSwap compare on L2s like Arbitrum and Base?
ParaSwap is particularly strong on L2s. Because gas is cheap on Arbitrum, Base, and Optimism, ParaSwap's multi-hop routing is almost always worth it even for small trades. Its fast quote generation and Save Gas mode (which groups multiple small trades efficiently) make it well-suited for the high-frequency, lower-value trading patterns typical of L2 DeFi users.
What is ParaSwap's Tensor NFT integration?
ParaSwap integrated Tensor, one of the largest NFT marketplaces on Solana, giving users the ability to trade NFTs through the same interface they use for token swaps. This makes ParaSwap unique among aggregators - it's the only one that bridges DeFi swapping with NFT trading. Tensor's integration means ParaSwap users can access NFT liquidity alongside DEX liquidity, all through one interface.
Is ParaSwap safe to use?
ParaSwap has processed over $20B in volume since launch and has undergone multiple security audits. Its Augustus protocol contracts are battle-tested. However, as with any DeFi protocol, there is smart contract risk. ParaSwap also uses intermediary token wrapping in some routes (via the TokenTransferProxy), which adds an additional contract interaction compared to a direct swap. Always use the official ParaSwap interface and verify contract addresses.
