5 DeFi Projects Tackling The Hidden Costs Of Onchain Trading
The fee your wallet shows before you hit “swap” is rarely the full cost of a trade. Slippage, price impact, liquidity scattered across dozens of venues, and clumsy execution can all quietly eat into what you actually receive. On a small swap, you might not notice. On a large one, it adds up fast.
As onchain trading has matured, a handful of teams have started going after these hidden costs from different angles. Here are five worth knowing about.
1. Orbs: More Ways to Execute a Trade
Most DEX trades are market orders: you swap now, at whatever price the pool gives you. Orbs adds options. Its Layer 3 infrastructure sits on top of existing decentralized exchanges and powers dLIMIT, which lets traders set limit orders, and dTWAP, which breaks a large order into smaller trades executed over time to soften its price impact.
Orbs also built Liquidity Hub, which lets DEXs tap liquidity sources beyond their own AMM pools. If an outside source offers a better price, the trade goes there. If not, it falls back to the regular swap. Either way, users never have to leave the exchange they’re already on.
2. CoW Swap: Letting Solvers Compete
CoW Swap flips the usual model. Instead of submitting a transaction that follows a fixed route, you sign an intent (essentially, “here’s what I want”), and a network of solvers competes to fill it at the best price.
When two traders want opposite sides of the same pair, CoW Swap can match them directly, skipping the AMM altogether. That’s the “coincidence of wants” behind the name. When there’s no match, solvers pull from external liquidity instead. Because orders settle in batches rather than sitting exposed in the public mempool, the design also guards against common forms of MEV, like sandwich attacks.
3. 1inch: Searching a Fragmented Market
The same token can trade at different prices on different DEXs at the same moment, and checking every venue by hand isn’t realistic. 1inch does that legwork for you. Its aggregation infrastructure scans liquidity sources and, when it helps, splits a single trade across several routes to land a better overall price.
4. 0x: Aggregation as a Building Block
Where many traders use 1inch directly, 0x mostly works behind the scenes. Its Swap API gives wallets, trading platforms, and other apps access to aggregated DEX liquidity. That way, developers can offer solid routing and execution without building an aggregator from scratch. A lot of the swaps that happen inside wallet apps run on infrastructure like this.
5. Uniswap: The Foundation Underneath
Much of the above ultimately depends on liquidity sitting in automated market makers. Uniswap played a central role in making that model mainstream: anyone can provide liquidity, and anyone can trade, no permission needed.
Its concentrated liquidity design lets LPs focus their capital within specific price ranges, deepening liquidity where trading actually happens. Later upgrades have continued to improve capital efficiency and market structure, showing that DeFi’s core layer is still evolving.
The Bottom Line
These projects work on different layers of the stack, from core liquidity to routing to execution logic. But they’re chasing the same goal: making decentralized markets cheaper and easier to use.
For traders, the takeaway is simple. The fee on the confirmation screen is only part of the story. How your trade gets executed, and by what, can matter just as much.
