Company profile
researched Aug 2026Frax Finance is a decentralized finance protocol built around stablecoin issuance. It has issued three stablecoins: FRAX, a USD-pegged asset; FPI (Frax Price Index), a stablecoin pegged to a basket of consumer goods rather than a national currency; and frxETH, a liquid staking derivative token pegged to ETH intended as a replacement for WETH in smart contracts, with sfrxETH as a complementary ERC-4626 token that accrues ETH staking rewards and MEV. FRAX circulates on more than 20 blockchains, with Ethereum, Fraxtal and Arbitrum the largest. The protocol originated the fractional-collateral stablecoin design and, per Fortune, moved to a fully collateralized model in 2023; its current stablecoin, frxUSD, is partly backed by BlackRock's tokenized treasury fund.
The ecosystem comprises several interlinked subprotocols: Fraxswap, a Uniswap V2-based AMM with time-weighted average market maker (TWAMM) orders used for collateral rebalancing and protocol-owned liquidity; BAMM, a borrow/lend module on Fraxswap that requires no external oracle; Fraxlend, a permissionless lending market for Frax-based stablecoins; Algorithmic Market Operations (AMO) contracts such as the Curve, Uniswap V3 and Fraxlend AMOs that deploy collateral to generate revenue; Fraxtal, a modular L2 chain based on Optimism technology using frxETH as its gas token and awarding FXTL points for on-chain activity; Frax Bonds (FXB), zero-coupon bond-like tokens auctioned below 1 FRAX and redeemable for 1 FRAX at maturity; staked FRAX (sFRAX), an ERC-4626 vault distributing protocol yield weekly; Fraxferry, an optimistic cross-chain transfer protocol for Frax tokens; and a Frax Oracle system. Governance runs on FXS, the base-layer governance token that accrues fees, revenue and excess collateral value, and veFXS, locked FXS granting voting power and farming boosts, with fixed, annually halving FXS emissions directed to gauges by veFXS voters.
Frax has also acted as an investor in other DeFi projects, participating in seed and early rounds for Anzen, Curvance and Prisma.
Founding story
Sam Kazemian, an Iranian-American software programmer and UCLA graduate who had previously co-founded the wiki-based encyclopedia Everipedia (now IQ.wiki) with Theodor Forselius in December 2014, began development of Frax as a fractional stablecoin protocol in 2019. Fortune reports the company was founded in 2020 by Kazemian, Jason Huan, Travis Moore and Stephen Moore, a former economic adviser to Donald Trump; the founding team was among the first to experiment with an algorithmic stablecoin that maintains its dollar peg through code-based adjustments rather than backing assets. The FRAX token itself launched on December 20, 2020, by Kazemian, Travis Moore and Jason Huan. Kazemian and Travis Moore remain advisers to Everipedia/IQ.wiki.
Business model
Frax operates as an on-chain protocol governed by FXS/veFXS holders. Revenue is generated by deploying collateral through Algorithmic Market Operations contracts and protocol-owned liquidity across venues such as Curve, Uniswap V3 and Fraxlend, and via its lending, AMM and staking subprotocols. Value accrues to the FXS governance token, which captures fees, revenue and excess collateral value, while part of protocol yield is distributed weekly to sFRAX stakers.
Fees and yield from protocol-owned collateral deployment (AMOs), lending (Fraxlend, BAMM), swap fees on Fraxswap, and staking/collateral yield, with proceeds accruing to FXS holders and partly redistributed to sFRAX stakers. Forbes cited $86 million of revenue in the project's first year of operation.
Traction
FRAX is deployed on over 20 chains with Ethereum, Fraxtal and Arbitrum the largest venues. Frax was the fifth-largest stablecoin by market capitalization as of January 2022 per DeFi Pulse, and Forbes cited $86 million of revenue in its first year of operation with eight employees. The team numbered 13 members as of November 8, 2024. Frax appears in Fortune's Crypto 100 ranking under stablecoins.
Latest developments
Frax's V3 stack introduced full collateralization, real-world-asset collateral, sFRAX staking vaults and Frax Bonds, alongside the Fraxtal L2 and its FXTL points program; frxETH V2 with anonymous validator pools was pending at the time of documentation. Fortune describes frxUSD as the protocol's current stablecoin, partly backed by BlackRock's tokenized treasury fund, with Sam Kazemian as CEO. Governance activity in 2024 included proposals on winding down or unlocking legacy Convex FRAX liquidity vaults.

Market position
Frax describes itself as the inventor of the fractional stablecoin and of the first crypto-native CPI-pegged asset, the Frax Price Index. As of January 2022 it ranked fifth among stablecoins by market capitalization per DeFi Pulse, and Fortune includes it in its Crypto 100 ranking in the stablecoins category. The protocol states that its subprotocols exist to create utility for and collateralize FRAX ecosystem tokens rather than to compete directly with larger incumbents such as Aave in lending or Uniswap in swaps.
Originator of the fractional-collateral stablecoin design and of the FPI 'flatcoin' pegged to a consumer-goods basket rather than a sovereign currency, giving it a unit of account independent of national money. Other distinguishing elements include the AMO framework for algorithmic collateral deployment, TWAMM orders in its native AMM, an oracle-free borrow AMM, and vertical integration down to its own Optimism-based L2 (Fraxtal) that uses frxETH as the gas token.
Technology
Smart-contract system spanning Ethereum and more than 20 chains. Components include Fraxswap, an AMM derived from Uniswap V2 with TWAMM order functionality; the AMO framework and AMO Minter for programmatic collateral management; Fraxlend for customized non-custodial loans and collateral onboarding; BAMM, which functions without external oracles or external liquidity by letting borrowers rent lender-provided liquidity to lever up and down; ERC-4626 vaults (sfrxETH, sFRAX); Fraxtal, an Optimism-based modular L2 using frxETH as gas token with Merkle proof oracles; the Frax Oracle system; and cross-chain transfer via Fraxferry and LayerZero/Stargate. frxETH V2 is expected to permit anonymous validator pools using escrowed exit messages as collateral to borrow additional ETH. Frax maintains a bug bounty and published audits.
Go-to-market
Distribution is on-chain and community-driven: FRAX and related tokens are deployed across more than 20 blockchains, liquidity and integrations are incentivized through the veFXS gauge voting system that directs fixed, halving FXS emissions to approved strategies, and the protocol coordinates through public documentation, a governance forum (gov.frax.finance), Snapshot voting, and Telegram, Discord, X and Medium channels. Frax also invests in adjacent DeFi projects.
On-chain users and DeFi participants seeking dollar-, CPI- and ETH-pegged assets; liquidity providers and stakers; borrowers and lenders on Fraxlend and BAMM; developers and protocols integrating Frax stablecoins or building on the Fraxtal L2.
Geography
Operates as a globally accessible on-chain protocol across more than 20 blockchains. A third-party company profile lists the Cayman Islands as its country of association.
History
Development of Frax as a fractional stablecoin began in 2019, and the FRAX token launched in December 2020. By January 2022 Frax ranked as the fifth-largest stablecoin by market capitalization according to DeFi Pulse. In 2022 the protocol issued FPI, described as the first known 'flatcoin' pegged to the Consumer Price Index, a category credited to Kazemian and Balaji Srinivasan. Kazemian was named to the Forbes 30 Under 30 in finance in 2023, with the listing citing $86 million of revenue in the project's first year of operation with eight employees. Frax moved from a fractional/algorithmic design to a fully collateralized stablecoin in 2023, subsequently launching V3 components including sFRAX, FXBs, real-world-asset collateral and the Fraxtal L2. Its current stablecoin is frxUSD.
Risks & controversies
The protocol's original design depended on algorithmic, partially collateralized peg maintenance before shifting to full collateralization in 2023. Governance discussions in 2024 show friction in legacy liquidity products: a proposal sought a paid shutdown of a Convex FRAX rETH/frxETH vault because the pool had almost no volume and lockers could not withdraw, with community members disagreeing over timing relative to the frxETH V2 launch; related proposals covered rage-quit fees and penalty-free unlocks for legacy vaults. Frax's stablecoin is also exposed to third-party collateral, including a tokenized BlackRock treasury fund.
