Uniswap vs SushiSwap: the protocol and the fork that drank its liquidity for a month
In August 2020 a pseudonymous developer cloned Uniswap, added a token, and siphoned over a billion dollars of its liquidity in days — then withdrew $14M, handed the keys to Sam Bankman-Fried, and returned the money apologizing. The strangest rivalry in DeFi history is also the most instructive one.
This is the oldest real rivalry in the DEX family, and it still frames every “fork vs original” argument. Uniswap invented the form; SushiSwap proved liquidity is mercenary by paying Uniswap's own LPs to defect — then detonated its own credibility, partially returned the money, and became a DAO soap opera while Uniswap shipped v3 and v4.
Every row below names its source and date.
The parameter table
| Parameter | Uniswap | SushiSwap |
|---|---|---|
| Origin | Nov-2018, Hayden Adams — the canonical constant-product AMM, funded by grants and Paradigm; deliberately tokenless for two years. | Aug-28-2020, pseudonymous “Chef Nomi” — a Uniswap fork that added SUSHI rewards to pull its liquidity; open warfare by design. |
| The attack | The target: SUSHI rewards were paid on Uniswap LP tokens, then the pooled liquidity migrated en masse — ~$1B+ moved, at peak draining the majority of Uniswap's TVL in about a week. | The weapon: “vampire mining” — incentivize the victim's LP tokens, then migrate them to the fork. It worked well enough to name a genre. |
| The September implosion | Uniswap answered Sep-17-2020 with the UNI launch — 400 UNI to every past user — the airdrop that ended the vampire season. | Sep-5-2020: Chef Nomi withdrew ~$14M in ETH/SUSHI from the dev fund “because I deserve it”; community revolted; control passed to SBF temporarily; Nomi returned the full $14M on Sep-11 and apologized (public record). |
| Governance shape | UNI + Labs/foundation split — protocol fees governed, company built separately. | Fully community-DAO — and repeatedly convulsed by it: Maki's Dec-2020 departure, the 2022 Joseph Delong/Frog Nation blowup, revolving head chefs. |
| Protocol evolution | v2 → v3 (concentrated liquidity, 2021) → v4 hooks (Jan-2025) — each version the industry's reference AMM. | Multi-product sprawl — AMM, lending (Kashi), launchpad (MISO), cross-chain ambitions; breadth over depth with rotating leadership. |
| Current scale | The dominant AMM across EVM + own chain plans; deepest liquidity venue on Ethereum. | Persisted as a mid-tier multichain DEX — alive, DAO-run, a fraction of its vampire-era TVL peak. |
| Incident file | No LP loss to protocol exploit on record; the Feb-2025 non-action closed the SEC file. | The original sin is governance-level, not contract-level — the dev-fund withdrawal was authorized by its own tokenomics, which is exactly why it mattered. |
The vampire attack, week by week
Aug-28-2020: Chef Nomi launches SushiSwap — a byte-level Uniswap fork plus one addition, a SUSHI token paid to anyone staking Uniswap LP tokens into its contracts. Within days it held over $1B of Uniswap's liquidity, roughly 70–80% of the pool at peak, scheduled to migrate to SushiSwap pools. It was permissionless composability used as a weapon: Uniswap couldn't stop it because nothing in the design required permission.
Sep-5: Nomi withdrew ~$14M from the dev fund — legal under the tokenomics he'd written, catastrophic optically. The community response forced him to hand admin control to Sam Bankman-Fried (of all people, in retrospect) as interim steward. Sep-11: Nomi returned the full $14M and apologized. Sep-17: Uniswap shipped UNI — 400 tokens to every address that had ever touched the protocol — and the vampire war was effectively over.
What each became
Uniswap grew into the reference implementation: v3's concentrated liquidity (2021) redefined AMM efficiency, v4's hooks (Jan-2025) turned the pool into a platform, and the Labs/protocol split kept a company shipping front ends while the contracts stay ownerless. The tokenless-to-UNI arc became the model.
SushiSwap became a governance endurance test: an early golden age under 0xMaki (who departed Dec-2020), the chaotic Frog-Nation-adjacent 2022 implosion under Joseph Delong, rotating head chefs after. It still ships — a real multichain AMM — but its TVL never revisited the vampire-era peak the same way; its lasting contribution is proof-of-concept that liquidity can be bought, not that it can be kept.
The structural lessons, five years on
Lesson one: mercenary liquidity is real and priced — SUSHI emissions bought the TVL and the end of emissions lost it; sustainable liquidity needed a reason beyond yield. Lesson two: anonymous founder + unrestricted dev fund is a disclosed rug mechanism, not a quirk — Nomi's withdrawal was contractually permitted, which is precisely the point about reading admin-key terms. Lesson three: the airdrop counterattack set the template — Uniswap's 400-UNI answer made “retroactive distribution to real users” the industry's standard loyalty defense.
Neither outcome was ordained by code quality: the same contracts powered both. The divergence was incentive design and governance continuity — the two things a fork can't copy.
The fork that refused to die, and why that matters
SushiSwap's post-attack survival is its own evidence file. After Nomi's return-and-apology, the protocol could have faded into a trivia answer; instead it built real products — Kashi lending, MISO launchpad, BentoBox vaults — and expanded across more chains than Uniswap did for years. Its collapse came from the top, not the contract: 0xMaki's quiet exit in Dec-2020 removed the one leader with community trust, and the 2022 implosion — Delong's departure accusing core contributors, Frog Nation chaos, treasury fights — showed what founderless governance costs when there is no Labs-style company holding the roadmap.
Uniswap's opposite structure paid off in exactly that dimension: the protocol stays ownerless while Uniswap Labs — a real company with real employees — ships the interface, the wallet, and the research. When the SEC came (Apr-2024 Wells notice), there was a legal entity to receive it, fight it, and close it Feb-2025 with no action. SushiSwap's DAO had to lawyer up as a collective, mid-leadership-vacuum.
The five-year verdict: the fork won the week and lost the decade — but it survived, which is more than most vampire attempts managed. Its existence permanently repriced what a liquidity moat is worth: after August 2020, every DEX knew its LPs could be bought, and every launch since has designed emissions with that knowledge.
Who should pick which
For most pairs and sizes, Uniswap — deepest liquidity, best tooling, the reference AMM. SushiSwap still earns usage on long-tail multichain routes where its pools hold residual depth, and aggregators will route through it when it wins — let the router decide per-trade rather than pledging venue loyalty. The historical file matters less as a guide to today's pricing than as the canonical case study in how liquidity, tokens, and trust actually interact.
Frequently asked
What was the SushiSwap vampire attack?
Aug-2020: a Uniswap fork paid SUSHI rewards to anyone staking Uniswap LP tokens, then migrated the pooled liquidity — pulling $1B+, the majority of Uniswap's TVL, in days. First large-scale liquidity-mining attack on a rival.
Did Chef Nomi rug SushiSwap?
He withdrew ~$14M from the dev fund on Sep-5-2020 — permitted by the tokenomics he wrote — then returned it in full on Sep-11 with an apology after community revolt and a brief SBF interregnum.
How did Uniswap respond?
The UNI token launch Sep-17-2020 — 400 UNI airdropped to every past user — which ended the vampire season and invented the retroactive-airdrop loyalty defense.
Is SushiSwap still running?
Yes — a live multichain DEX, DAO-governed, but a fraction of its vampire-era peak after years of leadership turnover (Maki, Delong, rotating head chefs).
Did SushiSwap get hacked?
Its canonical wound is governance-level, not contract-level: the $14M withdrawal was allowed by its own terms. The Aug-2022 Sushi frontend/router approvals drain was the contract-layer incident (check router approvals — a separate file).
Which is better for swapping today?
Uniswap on depth and tooling for most pairs; SushiSwap survives on long-tail multichain routes — an aggregator answers per-trade better than loyalty does.
