Ex-SushiSwap CTO Joseph DeLong to Launch Order-Book DEX ‘Deepstate’ on Robinhood Chain Next Week

Joseph DeLong — former SushiSwap CTO — says he’ll launch an order-book decentralized exchange called Deepstate on Robinhood Chain next week. He’s staking his DeFi credibility on a chain that’s already chewed through roughly $3.1 billion in DEX volume since launch. And he’s doing it without publishing a single technical specification, smart contract address, or tokenomics document.

DeLong broke the news on social media. “I have a decentralized exchange side project that outgrew nights and weekends. I’m gonna launch it next week on @robinhood chain,” he wrote. He currently runs Colossus, a stablecoin card startup. No word on whether Deepstate falls under that company’s umbrella or stands alone. The project’s name comes from The Defiant.

Order-Book vs AMM: The Architecture Bet

The architecture choice is the most technically interesting thing here. Deepstate is an order-book DEX — matching buyers and sellers directly instead of routing trades through automated market-making pools. AMMs, the architecture SushiSwap popularized, rely on liquidity providers and algorithmic pricing curves; order-book exchanges replicate centralized venues like Binance or Coinbase on-chain, delivering precise price control and limit orders but demanding deeper liquidity and faster settlement to function at all. On a chain built around retail flow? That trade-off could cut either way.

DeLong’s Track Record — and Its Limits

DeLong’s track record gives this weight. It also invites scrutiny. He resigned as SushiSwap’s CTO in December 2021 amid reports of internal turmoil, as Yahoo Finance documented — a chaotic stretch for a protocol that’s cycled through leadership controversies since its 2020 vampire-attack origin story. His technical reputation survived that exit intact enough to draw eyes now. But an announcement with no audit, no contract, and no tokenomics leaves users nothing to verify before launch. In a market where anonymous developers drain liquidity pools with regularity, the gap between credibility and transparency is exactly where risk lives.

Robinhood Chain: The Bigger Bet

Robinhood Chain is the bigger bet. The chain has recorded approximately $3.1 billion in DEX volume since launch; our desk previously reported it surpassed Coinbase’s Base on daily active users within three weeks. Driven by memecoin speculation — not the stock-token trading it was ostensibly built for. Uniswap has already deployed there, with a fee switch vote going live. A clear signal that major DeFi protocols regard the chain as viable for retail-facing activity. Deepstate’s order-book model would offer something Uniswap’s AMM architecture does not: limit orders. Which appeal to traders who want price discipline over slippage tolerance.

A Hostile Macro Backdrop

The macro backdrop? Less cooperative. Total crypto market cap sits at $2,269.06 billion, down 1.74% over 24 hours. The Fear & Greed Index reads 27 out of 100 — squarely Fear territory. BBTC$63,824.00▼2.30% trades at $63,962, off 2.4% on the day; EETH$1,852.95▼1.90% sits at $1,857, down 1.85%; SSOL$73.73▼2.80% has shed 2.62% to $73.97; ZZEC$473.98▼6.20% leads the losers with a 5.83% decline to $477. Risk appetite is compressed. Launching a new DEX into that environment means competing for liquidity against established venues that already have user bases, integrated wallets, and battle-tested contracts.

What Is DeLong Actually Shipping?

What is DeLong actually shipping? A side project that outgrew nights and weekends could mean a polished product ready for mainnet — or it could mean a minimum-viable contract pushed live to capitalize on Robinhood Chain’s momentum. Without published specs, there’s no way to distinguish the two from the outside. The order-book model itself is technically demanding; it requires either a high-throughput execution environment or an off-chain matching engine with on-chain settlement. Neither approach has been confirmed.

One thing is confirmed: the date. DeLong says next week. Robinhood Chain’s volume and user base suggest the demand side exists. Whether Deepstate can capture any of it — and whether the code behind it holds up under live conditions — traders will only learn once contracts are deployed and the first orders hit the book.
