The rise of Uniswap marked a pivotal moment in blockchain history—the first time a decentralized exchange (DEX) emerged with real competitive strength against centralized platforms. For newcomers who entered the crypto space in the past few years, interacting with DeFi through tools like MetaMask, swapping tokens on Uniswap, or farming airdrops across Layer 2 networks feels completely natural—almost like second nature.
But this ease of use didn’t come overnight. Behind the seamless user experience lies nearly seven years of experimentation, failure, and innovation. The evolution of DEXs unfolded through distinct phases: from BitShares’ early vision, to EtherDelta’s bold but flawed execution, to 0x’s hybrid approach, and Bancor/Kyber’s introduction of automated market makers (AMM). Each step brought the ecosystem closer to a breakthrough—until Uniswap finally achieved what others couldn’t: true scalability, openness, and community-driven growth.
For those of us who lived through every phase, Uniswap isn’t just another protocol—it’s the hard-won result of two market cycles, countless failed experiments, and persistent belief in decentralization.

The First Decentralized Exchange: BitShares (BTS)
BitShares was a visionary project ahead of its time. It introduced groundbreaking concepts such as decentralized trading, algorithmic stablecoins (like bitUSD and bitCNY), and on-chain asset backing—many of which became foundational elements of modern DeFi.
Notably, both Vitalik Buterin and Rune Christensen (founder of MakerDAO) were once active members of the BitShares community. In fact, Rune developed the idea for MakerDAO’s DAI stablecoin after his experience with BitShares’ flawed yet innovative price-stable assets.
Despite its innovations, BitShares ultimately faded into obscurity. Two critical flaws sealed its fate:
- No smart contract functionality – Without the ability to create new assets or complex financial instruments, the ecosystem stagnated. There were no compelling use cases beyond basic token swaps.
- Order book model on-chain doesn’t scale – BitShares replicated centralized exchange mechanics using an on-chain order book. This led to poor liquidity depth and slow execution. Even at its peak, only BTS itself had meaningful trading volume; other assets had negligible orders.
I was a dedicated BTS holder and user in 2017, even running a small on-chain settlement service within the network. But I eventually realized that without composability and developer activity, no amount of decentralization could sustain long-term adoption.
Ethereum’s First DEX: EtherDelta
Inspired by BitShares, developers launched EtherDelta—the first decentralized exchange on Ethereum. Like its predecessor, it used an on-chain order book model, where every action (listing, buying, selling) required a transaction and gas fee.
While technically similar to BitShares, EtherDelta operated on a slower and more expensive network. However, it planted a crucial seed: the concept of early-stage token discovery.
In 2017, savvy traders began hunting for promising new tokens exclusively listed on EtherDelta before they hit centralized exchanges. One famous example is MANA (Decentraland)—early buyers who purchased MANA on EtherDelta saw returns of 10x or more when it later listed on Binance and others.
Despite this innovation, EtherDelta failed due to three core issues:
- Slow transaction finality
- High gas costs
- Poor user experience from on-chain order books
It proved that simply porting centralized exchange logic onto Ethereum wasn’t enough.

Bridging On-Chain and Off-Chain: The 0x Protocol
After EtherDelta’s shortcomings became clear, the 0x team introduced a smarter hybrid model: off-chain order books with on-chain settlements. Orders were broadcast off-chain (reducing congestion), while trades settled securely on Ethereum.
This made 0x a liquidity protocol rather than just an exchange. Developers could build their own frontends powered by 0x’s shared liquidity pool. One notable example was DDEX, which at one point accounted for over 50% of 0x’s trading volume.
When DDEX forked 0x to go independent, it revealed a harsh truth: user acquisition is easier than building liquidity. Without deep order books, even polished interfaces struggled to retain users.
Though 0x gained traction during the 2018–2019 bear market and briefly outperformed peers, it never closed the gap with centralized exchanges. At its peak, the entire 0x ecosystem served only 100–200 daily active traders, highlighting the limits of incremental improvements in DeFi.
I learned a key lesson here: decentralization alone isn’t a strong enough value proposition unless it enables something fundamentally new.
The Rise of Automated Market Makers: Bancor and Kyber
Around the same time, two projects—Bancor and Kyber Network—pioneered the Automated Market Maker (AMM) model, replacing order books with liquidity pools governed by mathematical formulas.
Bancor: Visionary but Flawed
Bancor raised a staggering $150 million in its 2017 ICO—a record at the time. It used an AMM system where all trades routed through BNT, its native token acting as a connector currency.
However, forcing BNT into every trade created unnecessary friction. Worse, listing new tokens required manual approval from the Bancor team. After two years, only 13 tokens were available—far too few to meet market demand.
Kyber: Simpler, More Flexible
Kyber improved upon Bancor by using ETH as the primary reserve asset, reducing slippage and complexity. It also allowed more tokens to be listed faster. By late 2019, Kyber had pulled ahead in terms of volume and usability.
Still, both platforms struggled with low liquidity compared to centralized exchanges—a problem that would soon be solved by a new entrant.
The Game Changer: Uniswap Emerges
In late 2019, a quiet project began gaining attention: Uniswap. At first, I dismissed it—I was invested in ZRX (0x) and KNC (Kyber), after all. Why support a competitor?
But by early 2020, reality set in. Uniswap’s growth was explosive.
Powered by the elegant x × y = k constant product formula and permissionless token listings, Uniswap attracted developers and liquidity providers alike. Its V2 release enabled direct ERC-20-to-ERC-20 swaps and integrated price oracles.
Within months:
- Daily volume jumped from $300k to $3M
- Then surged past $10M, outpacing Kyber and 0x
- By September 2020’s UNI token launch—and subsequent dip to $2—I admitted defeat and swapped half my ZRX for UNI
I’ve held UNI ever since. Not because I blindly believe in hype—but because I witnessed firsthand how Uniswap solved the two biggest DEX challenges:
- Liquidity provision via LP incentives
- True permissionless innovation—anyone can list any token
For the first time, decentralization wasn’t just about security—it offered something centralized exchanges couldn’t match.
Why Uniswap Changed Everything
Uniswap achieved what others failed to do: it created a paradigm shift. Instead of mimicking CEX structures, it redefined what an exchange could be:
- Open access for any developer
- Composability with other DeFi protocols
- Community ownership through UNI governance
Its success proved that when decentralization delivers unique utility—not just ideology—it can win.
Uniswap vs. Uniswap Labs: Understanding the Divide
A recent controversy sparked debate: Uniswap Labs clarified that the official website and wallet are its proprietary assets, while only the core protocol belongs to the community (UNI holders).
This upset many who believed owning UNI meant owning all things "Uniswap." But technically, Uniswap Labs is a company that builds tools around the open-source protocol. The smart contracts (V1–V4, Uniswap X) live on-chain and are community-owned; frontend apps do not.
Think of it like Firefox (Mozilla) vs. the internet itself—the browser isn’t the web.
Final Thoughts: What UNI Really Represents
After living through every failed DEX experiment, my perspective is shaped by scars—and hope.
Short-term, UNI can be seen as equity in Uniswap Labs’ revenue-generating products (like wallet fees).
Long-term? It represents ownership in one of crypto’s most vital public infrastructures—a protocol that will persist even if the company behind it disappears.
That’s why I hold. Not out of loyalty—but conviction.
