Felix Protocol vs Hyperliquid

Felix Protocol

Felix Protocol is the primary stablecoin issuance and money market platform on Hyperliquid's HyperEVM, functioning as both a collateralized debt position (CDP) engine and a variable-rate lending marketplace. Built natively on HyperEVM, Felix has established itself as one of the largest DeFi protocols in the Hyperliquid ecosystem, having crossed $1 billion in total value locked in September 2025 before settling to approximately $440 million TVL by October 2025. The protocol's core thesis is that Hyperliquid's on-chain liquidity and composability create the ideal environment for a stablecoin primitive that earns real yield for its users rather than extracting value from them. WHAT IT IS Felix operates two distinct but complementary products: a CDP system that mints feUSD (a dollar-pegged synthetic stablecoin) against on-chain collateral, and Vanilla Markets, which are variable-rate lending pools for borrowing and earning yield against major assets. The protocol has also launched USDhl, a fiat-backed, T-bill-collateralized stablecoin powered by M0 (a wholesale dollar infrastructure), broadening Felix's stablecoin suite beyond purely algorithmic constructions. Together, these products position Felix as the stablecoin factory and lending backbone for the HyperEVM ecosystem. HOW IT WORKS The feUSD CDP system is built on a fork of Liquity v2's codebase, modified with additional risk controls suited to Hyperliquid's asset landscape. Users deposit accepted collateral — HYPE, wrapped BTC (UBTC), and liquid staking tokens like kHYPE — into Troves (individual CDP vaults) and mint feUSD against it at a conservative 40% loan-to-value ratio. This is notably lower than most DeFi lending platforms, a deliberate choice to limit systemic risk given the relative volatility of the collateral base. feUSD holders can redeem their tokens for $1 worth of underlying collateral at any time, and a Stability Pool absorbs liquidated positions, distributing collateral and earned interest to Stability Pool depositors. Interest rate selection is borrower-controlled, but positions with the lowest interest rates face first-redemption risk if feUSD depegs below $1 — a soft liquidation mechanism that enforces peg discipline. Vanilla Markets, the second pillar, are variable-rate lending pools built on Morpho's lending infrastructure. Lenders deposit stablecoins (USDhl, USDe, USDT0, USDH) and earn variable interest, while borrowers post collateral (HYPE, kHYPE, UBTC) to borrow. Interest rates adjust algorithmically with pool utilization, and liquidations execute automatically when a borrower's health factor falls below 1. All positions are over-collateralized. The July 2025 CoreWriter upgrade — which enables HyperEVM smart contracts to write data to HyperCore — means Felix can now route liquidations directly through HyperCore's orderbook rather than AMM pools, reducing slippage and creating tighter integration with Hyperliquid's core liquidity engine. USDhl, the third product, is a fiat-backed stablecoin issued via M0, a wholesale dollar infrastructure backed by T-bills with on-chain reserve attestations. Convertibility is enforced at 1:1 between M0 tokens and USD, and a maintained Uniswap v3 liquidity pool ensures low-friction arbitrage. The stablecoin distributes its 4%+ T-bill yield back to users as Hyperliquid incentives, split across HyperCore spot and HyperEVM liquidity pools and reweighted every two weeks. KEY FEATURES - Dual stablecoin architecture: feUSD (CDP, algorithmic peg via Liquity v2 mechanics) and USDhl (fiat-backed, M0-powered, yield-distributing) serve different user needs and risk profiles from a single platform. - Morpho-powered Vanilla Markets: Variable-rate lending pools with dynamic interest rates and automatic on-chain liquidations. Supports HYPE, kHYPE, UBTC as collateral against stablecoin borrowing. - CoreWriter liquidation integration: Since July 2025, Felix can programmatically send liquidation orders to HyperCore's orderbook, reducing slippage and execution risk during market stress. - Conservative risk parameters: 40% LTV cap on CDP positions, mint caps, admin-controlled pause mechanisms, and incremental collateral onboarding — reflecting a deliberate approach to risk management in a novel ecosystem. - Points and incentive program: An ongoing points program rewards users for minting feUSD, supplying to Vanilla Markets, and holding USDhl, creating strong growth incentives while the governance token remains unlaunched. TEAM AND BACKING Felix has operated without publicly naming its founding team, maintaining a degree of pseudonymity common in the Hyperliquid ecosystem. The project launched on HyperEVM shortly after the mainnet EVM became available in early 2025 and has not announced formal venture funding rounds as of the time of writing. The protocol operates under the usefelix.xyz domain and has an active development roadmap that includes "Chapter 2" — a planned expansion expected to unify incentive structures across HyperCore and HyperEVM and introduce new collateral types and evolved risk parameters. Community messaging has described Chapter 2 as a significant protocol upgrade aligned with full CoreWriter integration. Felix has maintained a partnership with Hyperion DeFi, a NASDAQ-listed company that has integrated with Felix's broader product suite. TRACTION AND METRICS Felix launched on HyperEVM in early 2025 and grew rapidly alongside the broader HyperEVM ecosystem. By June 2025, the protocol had crossed $100 million in outstanding loans — a milestone reported by The Defiant. September 2025 marked its all-time high with over $1 billion in TVL, as HyperEVM total TVL itself surged 350% in two months. As of October 2025, Felix held approximately $440 million in TVL, making it the second-largest native DeFi protocol on HyperEVM by this metric behind HyperLend. The protocol has accumulated significant volume through its Stability Pool mechanism and Vanilla Markets, with HYPE and UBTC serving as the primary collateral assets driving growth. An active points program has sustained user engagement and encouraged protocol experimentation. COMPETITIVE POSITION Within the HyperEVM ecosystem, Felix competes most directly with HyperLend for lending market share. Felix's differentiation lies in its CDP stablecoin product (feUSD), which HyperLend does not offer, and in the more conservative, risk-adjusted design of its collateral parameters. Versus Liquity on Ethereum, Felix inherits architectural inspiration but layers in pause mechanisms and admin controls that Liquity deliberately avoids — a trade-off between censorship resistance and pragmatic risk management. Against MakerDAO/Sky on Ethereum, Felix benefits from Hyperliquid's throughput and HyperCore composability. The USDhl product competes with Ethena's USDe and other yield-bearing stablecoins, but is differentiated by its M0 T-bill backing and distribution of real yield back to Hyperliquid participants rather than to protocol treasuries. HYPERLIQUID INTEGRATION Felix is architected exclusively for HyperEVM and deeply integrates with HyperCore at multiple levels. The feUSD CDP system accepts HYPE (HyperCore's native staking token) and kHYPE (Kinetiq's HyperCore-staked liquid staking token) as collateral — assets that are native to the Hyperliquid L1. The Vanilla Markets build on Morpho, which itself relies on HyperEVM's EVM execution. USDhl's yield distribution is routed through HyperCore spot market liquidity incentives. Critically, CoreWriter integration allows Felix to place liquidation orders directly on HyperCore's CLOB rather than routing through AMM pools — making Felix one of the first protocols to actively exploit the bidirectional HyperCore-HyperEVM bridge at a liquidation engine level. Felix's points program allocates rewards across both HyperCore spot and HyperEVM, incentivizing the dual-layer activity that is central to Hyperliquid's long-term design. RISKS AND CONSIDERATIONS The 40% LTV ratio provides a reasonable buffer against collateral volatility, but HYPE is the dominant collateral and is itself a relatively illiquid and volatile asset by traditional standards. A severe HYPE price shock could trigger cascading liquidations that test the Stability Pool's absorptive capacity and the CoreWriter liquidation pipeline. The feUSD peg mechanism's reliance on redemption pressure means that during market stress, borrowers with low interest rates face forced liquidation through redemption — a mechanism that is economically sound but can create adverse user experiences. The protocol's admin-controlled pause functionality and mint caps represent meaningful centralization versus Liquity's immutable design. Team pseudonymity creates limited accountability in the event of critical vulnerabilities or governance disputes. Governance token launch (not yet live as of the research period) introduces tokenomics uncertainty. Dependency on Morpho for Vanilla Markets means Felix inherits any bugs or risks from the Morpho lending infrastructure. Overall, Felix is well-designed for its environment but carries ecosystem concentration risk — its growth is tightly coupled to HYPE's price trajectory and HyperEVM's adoption curve.

Hyperliquid

Hyperliquid is a purpose-built Layer 1 blockchain and the dominant decentralized perpetuals exchange in crypto, processing up to $30 billion in daily trading volume as of late 2025. Unlike most DeFi protocols that deploy on existing chains, Hyperliquid built its own L1 from first principles to achieve performance rivaling centralized exchanges — with sub-second finality, zero gas fees for users, and a fully on-chain order book. The project has rapidly become the benchmark for what a decentralized trading venue can achieve, capturing over 80% of the decentralized perpetuals market by trading volume in under two years. WHAT IT IS Hyperliquid operates as a vertically integrated financial platform with two core layers: HyperCore and HyperEVM. HyperCore is the original perpetual futures and spot trading engine — a fully on-chain Central Limit Order Book (CLOB) running natively on the L1 that executes orders with one-block finality and processes 200,000 orders per second. HyperEVM is a general-purpose EVM-compatible execution environment that shares the same consensus layer as HyperCore, allowing smart contract developers to tap into HyperCore's deep liquidity as a native building block. Together, they form a unified stack unlike any other chain: the speed and depth of a centralized exchange combined with the programmability and transparency of a decentralized blockchain. HOW IT WORKS Hyperliquid's consensus mechanism, HyperBFT, is a custom Byzantine Fault Tolerant algorithm inspired by HotStuff and its successors. The entire networking stack was built from scratch to support the unique throughput demands of financial markets. Every order, cancellation, trade, and liquidation is recorded on-chain with full transparency, making it verifiably auditable in real time. The dual-layer architecture is central to Hyperliquid's design philosophy. HyperCore manages margin state, perpetual matching, and spot orderbooks. HyperEVM runs alongside HyperCore within the same consensus round, meaning smart contracts on HyperEVM can read from and — via the July 2025 CoreWriter upgrade — write directly to HyperCore. This bidirectional bridge enables DeFi protocols built on HyperEVM to execute liquidations, route orders, and interact with the orderbook at the protocol level rather than through wrappers or bridges. Key protocol standards include HIP-1 (native spot token creation), HIP-2 (automated liquidity provisioning on spot), and HIP-3 (permissionless deployment of perpetual futures markets by any team that stakes HYPE as collateral). HIP-3 in particular is transformational: it democratizes the creation of new perp markets in a way that no other exchange — centralized or decentralized — offers. Builder Codes allow UI operators to collect fees directly from trades routed through their front-ends, with builders capturing more protocol fees than Hyperliquid itself on some metrics. KEY FEATURES - Fully on-chain CLOB: Every order and trade is transparently settled on L1, with one-block finality and no MEV at the sequencer level. HyperCore processes 200,000 orders per second, benchmarking against top-tier centralized exchanges. - HyperEVM composability: DeFi protocols built on HyperEVM access HyperCore liquidity natively. CoreWriter enables smart contracts to trigger HyperCore actions — liquidate positions, post orders, read real-time market state — creating a true DeFi x CEX hybrid. - HIP-3 permissionless markets: Any team can deploy a perpetual futures market on HyperCore by staking HYPE as collateral. This has spawned an ecosystem of builder-operated exchanges and tokenized real-world asset perps. - Zero gas fees: Users on HyperCore pay no gas fees; the protocol funds operations entirely from trading fees, which flow back to the community via the Assistance Fund and fee sharing programs. - HYPE token economics: HYPE holders earn staking rewards and receive reduced trading fees. 31% of total supply was distributed via airdrop in November 2024 — among the largest token distributions in crypto history. TEAM AND BACKING Hyperliquid was co-founded in 2022 by Jeff Yan and a pseudonymous collaborator known as iliensinc. Yan is a Harvard University graduate who previously worked in high-frequency trading at Hudson River Trading before launching his own market-making operation. The FTX collapse in November 2022 was the catalytic moment — Yan identified the gap for a transparent, performant, self-custodial alternative to centralized exchanges and pivoted to building Hyperliquid. The core team comprises approximately 10 to 11 people drawing from Harvard, MIT, and Caltech, with backgrounds at elite trading firms including Citadel. In a rare demonstration of conviction for the space, Hyperliquid accepted zero venture capital funding. The project was entirely self-funded through proprietary trading revenues and early protocol fees. This preserved full community-first economics from day one. Hyperliquid's 2025 year-end summary confirmed that all protocol fees have been returned to the community without any external investor dilution. TRACTION AND METRICS Hyperliquid launched in closed alpha in February 2023, went to open mainnet in June 2023, and executed its HYPE token generation event on November 29, 2024. The airdrop distributed over $1.6 billion worth of HYPE tokens to approximately 94,000 early users — the largest airdrop in crypto history at the time by dollar value. Following the TGE, HYPE surged over 500% within months. By end of 2025, the platform reported $3.2 billion in 24-hour trading volume, $6 billion in total value locked, and consistent 80%+ market share across all decentralized perpetuals venues. Daily volume peaked near $30 billion on some pairs, approaching Binance-level depth for certain markets. Cumulative trading volume surpassed $1 trillion by early 2025. The HyperEVM ecosystem launched in early 2025 and grew from $350 million to $1.58 billion in TVL within two months, with dozens of DeFi protocols deploying natively. COMPETITIVE POSITION Hyperliquid competes primarily with dYdX, GMX, Drift Protocol, and traditional centralized exchanges. Its ascent is one of the most dramatic market share shifts in DeFi history: dYdX held 73% of the decentralized perps market at the start of 2024 and collapsed to 7% by year-end as Hyperliquid captured the dominant share. Unlike GMX and similar AMM-based perp venues, Hyperliquid's CLOB model provides accurate price discovery and CEX-like execution quality. Against pure L2 deployments like Synthetix on Base or Vertex on Arbitrum, HyperCore's purpose-built L1 removes dependence on Ethereum block times and gas market volatility. The HyperEVM ecosystem represents a direct competitive challenge to Solana and Base as preferred environments for financial DeFi applications. HYPERLIQUID INTEGRATION Hyperliquid is itself the integration point — the entire platform IS the L1, the exchange, and the DeFi base layer simultaneously. HyperCore is the core trading product; HyperEVM extends it with programmable smart contracts. HIP-3 enables third-party teams to deploy their own perpetual markets on the same shared infrastructure. Staked HYPE directly secures the validator network and powers HIP-3 market authorizations. Native protocols including Felix, HyperLend, Kinetiq, and HyperBeat build on HyperEVM, using precompile addresses starting at 0x0000000000000000000000000000000000000800 to query real-time HyperCore state — and since CoreWriter, to write orders and liquidations back to the matching engine. The result is a composable financial stack where orderbook depth and DeFi primitives are not siloed but architecturally unified. RISKS AND CONSIDERATIONS Hyperliquid's greatest strength — a fully custom stack built and maintained by a lean, self-funded team — is simultaneously its most significant risk vector. The HyperBFT consensus algorithm, while technically sophisticated, has not been battle-tested at the same depth or duration as Ethereum's Gasper or other established mechanisms. The small team creates key-person dependency, and the proprietary codebase limits external security review. Centralization of the validator set remains a concern as the network is still relatively young and expanding. HYPE's dramatic post-airdrop price appreciation introduces reflexive risk: a sustained price decline would reduce the economic security of HIP-3 markets and staking rewards simultaneously, potentially triggering negative feedback loops. Smart contract risk on HyperEVM follows standard EVM threat models, compounded by the novel precompile architecture. Regulatory risk around permissionless perp markets via HIP-3 — especially for markets on equities, commodities, and forex — is unaddressed. Maintaining 80%+ market share while expanding into general-purpose DeFi infrastructure presents an unprecedented operational challenge for a team of this size.
