At Solana Breakpoint 2025, Ellipsis Labs CEO Eugene Chen unveiled Phoenix Perpetuals—a fully on-chain derivatives exchange that could fundamentally change how perpetual futures trade on blockchain.
Building on the success of their spot DEX (which has processed over $75 billion in volume), Ellipsis Labs is bringing the same high-performance infrastructure to the derivatives market, currently crypto's largest trading category.
What Makes Phoenix Different: Crankless, Gasless, Fully On-Chain
Traditional on-chain derivatives exchanges face a fundamental tradeoff: they either sacrifice performance for decentralization or compromise on being truly on-chain. Phoenix Perpetuals solves this through several technical innovations:
Crankless Orderbook Technology
Most on-chain orderbooks require "cranks"—external keeper bots that process orders and update state. Phoenix eliminates cranks entirely through its proprietary verifiable crankless architecture, allowing orders to execute and update in real-time without relying on external actors.
Gasless Trading for Retail Users
Users don't pay gas fees for trading. Phoenix abstracts away blockchain transaction costs, making the user experience comparable to centralized exchanges while preserving on-chain settlement.
Fully On-Chain Risk Engine and Matching
Unlike competitors that use off-chain matching with on-chain settlement, Phoenix runs its entire risk assessment and matching engine on-chain.
The Liquidity Innovation
Phoenix Perpetuals introduces "proprietary AMM-style innovations" for derivatives that dramatically reduce the cost for market makers to provide and update liquidity. This hybrid approach allows market makers to update liquidity more cheaply than traditional orderbooks while supporting tighter spreads.
Performance Benchmark
Phoenix Perpetuals executed an $8 million trade with less than 1 basis point of slippage—less than $800 in price impact on a multi-million dollar order.
Market Opportunity: The Derivatives Dominance
Perpetual futures represent crypto's largest market by volume. Phoenix Perpetuals targets this massive gap: traders who want decentralized, non-custodial trading but refuse to accept the performance compromises that historically came with on-chain execution.
This isn't just another DEX—it's an attempt to prove that truly decentralized, fully on-chain derivatives can match the performance users expect from centralized platforms.
Implications for Solana DeFi
Phoenix's launch strengthens Solana's position as the high-performance blockchain for financial applications. With Phoenix offering both spot and perpetual futures on the same infrastructure, Solana gains a more cohesive trading ecosystem where traders can execute complex strategies across spot and derivatives.
Beta Launch and Gradual Rollout
Phoenix Perpetuals launched in private beta on December 11, 2025. Access is being distributed gradually through a structured rollout to ensure infrastructure scales properly and maintain quality as volume increases.
Conclusion
With sub-1 bps slippage on $8 million trades, gasless execution, and a crankless architecture built on proven infrastructure, Phoenix has the technical foundation to succeed. It serves as evidence that Solana's high-performance architecture enables financial applications impossible on other blockchains.
