What is Frax (FRAX)?

Frax is a comprehensive DeFi platform that combines stablecoins and subprotocols to create a dynamic financial ecosystem. It currently issues three stablecoins: frxUSD (pegged to USD), FPI (the Frax Price Index stablecoin, tied to a basket of consumer goods), and frxETH (a liquid staking derivative pegged to ETH). The Frax ecosystem also includes subprotocols like Fraxswap, Fraxlend, and BAMM (Borrow AMM), as well as Fraxtal, a Layer 2 (L2) blockchain. Frax leverages Algorithmic Market Operations (AMOs) to manage protocol-owned liquidity (POL), with the FRAX token serving as the native gas token for Fraxtal. Backed by $1.21 million in funding, Frax is supported by a vibrant community.

Purpose of Frax

Project aims to deliver decentralized financial solutions through stablecoins and DeFi protocols. It enables users to conduct secure, transparent, and efficient transactions. frxUSD provides a stable fiat-backed asset, FPI establishes an independent unit of account, and frxETH simplifies Ethereum staking for yield generation. Fraxtal offers low-cost transactions and rapid scalability. Frax fosters a community-driven ecosystem that encourages value creation and sharing for both users and protocols.

How Does Frax Work?

Project operates as a multi-layered ecosystem, integrating stablecoins and subprotocols to address diverse financial needs. Each component is designed to work seamlessly together. Here are the key elements:

Stablecoins

• frxUSD: A 1:1 USD-pegged, fully collateralized stablecoin backed by tokenized U.S. Treasury funds (e.g., BlackRock BUIDL, Superstate USTB). Managed by Frax Inc under Frax DAO delegation, it ensures 1:1 reserves with regulated custodians, handling custody, KYC/KYB compliance, and fiat redemptions.

• FPI: The first stablecoin pegged to a consumer goods basket, offering a unit of account independent of national currencies.

• frxETH: A liquid staking derivative pegged to ETH. Its counterpart, sfrxETH, accrues staking rewards. frxETH V2 supports anonymous validator pools.

Subprotocols

• Fraxswap: A Uniswap V2-based AMM with a time-weighted average market maker (TWAMM) feature, used for collateral rebalancing, stablecoin supply management, and liquidity deployment.

• BAMM (Borrow AMM): A borrowing/lending module built on Fraxswap, requiring no external oracles or liquidity. Borrowers remain solvent during high volatility.

• Fraxlend: A permissionless lending market enabling isolated pair-based borrowing and collateral onboarding. Maximum loan-to-value (LTV) ratios are community-determined.

• AMOs / POL: Algorithmic Market Operations manage collateral and generate revenue, including Fraxlend AMO, Curve AMO, and Uniswap V3 AMO.

• Fraxtal: An Optimism-based L2 chain using its token as its gas token. Users earn FXTL points through gas spending and pool farming.

• Frax Bonds (FXB): Zero-coupon bond-like tokens convertible to LFRAX at maturity, aiding peg stabilization.

• sfrxUSD: An ERC4626-based yielding stablecoin that distributes weekly protocol yields, selecting the best strategy (carry-trade, AMO, or IORB/T-Bill).

• veFRAX: Locking FRAX tokens grants voting power and enhanced farming weights.

Transaction Process:

1. Users deposit fiat or collateral for frxUSD, minted via custodians.

2. Staking in sfrxUSD yields returns.

3. Fraxswap or Fraxlend facilitates liquidity provision or borrowing.

4. FXBs are purchased at a discount and redeemed for LFRAX at maturity.

5. Transactions on Fraxtal using FRAX earn FXTL points.

Use Cases

Project supports:

• Stablecoin Transactions: frxUSD, FPI, and frxETH for payments, savings, or DeFi operations.

• Yield Generation: sfrxUSD and sfrxETH for staking returns.

• Borrowing/Lending: Fraxlend and BAMM for collateral-based transactions.

• Liquidity Provision: AMM pools on Fraxswap.

• Governance: veFRAX for protocol decision-making.

• Fraxtal: Low-cost L2 transactions and FXTL rewards.

Usage Steps:

1. Connect a wallet to the Frax platform.

2. Acquire frxUSD, FPI, or frxETH.

3. Engage with Fraxswap, Fraxlend, or BAMM.

4. Stake sfrxUSD/sfrxETH or purchase FXBs.

5. Transact on Fraxtal to earn FXTL points.

Advantages

• Stability: Fully collateralized stablecoins.

• Yield: Competitive APY via sfrxUSD and sfrxETH.

• Permissionless Access: Fraxswap and Fraxlend allow open participation.

• Modularity: Fraxtal enables low-cost transactions.

• Community-Driven: veFRAX and FXTL incentivize engagement.

Risks

• Market Risk: Stablecoin peg fluctuations.

• Technical Risk: Smart contract vulnerabilities.

• Regulatory Risk: Legal challenges for fiat-backed stablecoins.

• Volatility: Market dependency for frxETH and FXBs.

Frax Tokenomics

Maximum Supply: 99.68 million FRAX.

• Distribution:

  • Community: 64.89%

  • Team/Founders/Early Members: 20.06%

  • Accredited Private Investors: 12.04%

  • Strategic Advisors/External Early Contributors: 3.01%

Emission Schedule:

• Initial 8% annual inflation (FIP-428), decreasing 1% yearly, stabilizing at 3% after 6 years.

• Emissions fund community initiatives, Fraxtal growth, team expansion, and DAO treasury.

• Frax Burn Engine (FBE) reduces supply by burning FRAX tokens (e.g., via FNS Registrar, Fraxtal EIP1559 fees).

Cross-Chain Strategy:

• OFT (Omnichain Fungible Token): frxUSD, sfrxUSD, frxETH, sfrxETH, WFRAX, and FPI are transferable via LayerZero.

• Dual-Lockbox: Liquidity exits on Fraxtal and Ethereum.

• Hub Model: Fraxtal-centric “Hop” contracts streamline bridging.

• WFRAX vs. FXS: WFRAX is the LayerZero OFT; FXS is the legacy Ethereum version.

What is Legacy Frax Dollar (FRAX)?

Legacy Frax Dollar (FRAX) is the cornerstone stablecoin of the Frax Protocol, pegged 1:1 to the USD and backed by high-quality reserves. Each FRAX token is supported by cash-equivalent reserves like tokenized U.S. Treasury funds (e.g., BUIDL, USTB, JTRSY, WTGXX, AUSD), custodied by regulated entities and overseen by Frax Inc under Frax DAO’s delegation. FRAX integrates with other tokens in the ecosystem, such as FPI (pegged to a consumer goods basket), frxETH (an ETH-pegged liquid staking derivative), and sfrxUSD (a yield-bearing stablecoin). Sub-protocols include Fraxswap (a TWAMM-enabled AMM), BAMM (lending module), Fraxlend (permissionless lending), AMOs (algorithmic market operations), and Fraxtal (an L2 chain using FRAX as gas token).

The Frax ecosystem also features FXB (zero-coupon bonds) and veFRAX (voting and staking token) to ensure stability and yield. FRAX serves as liquidity and collateral in DeFi, with reserve management critical for maintaining its peg.

Purpose of Legacy Frax Dollar (FRAX)

Legacy Frax Dollar aims to empower the Frax Protocol by managing collateral and generating yield as a USD-pegged digital asset. sfrxUSD delivers the highest risk-adjusted yield through strategies like carry-trade, AMOs, and IORB/T-Bill rates. Fraxtal, an Optimism-based Layer-2 chain, uses FRAX as its gas token. Frax Bonds (FXB) stabilize the peg by reducing FRAX supply and locking liquidity. The protocol fosters trust through decentralized governance and transparency, with Frax Inc handling reserve management, KYC/KYB compliance, audits, and fiat redemptions. Governed by the Frax DAO under FIP-432, Frax Inc’s authority can be amended or revoked by the DAO at any time.

How Does Legacy Frax Dollar (FRAX) Work?

FRAX is backed 1:1 by cash-equivalent reserves. Frax Inc manages reserves, coordinates audits, and maintains fiat redemptions. FRAX operates permissionlessly, though reserve tokens may have additional requirements (e.g., whitelists). Users interact with frxUSDCustodian contracts for minting and redemption.

Key Features

• Market Registry: Betting markets are created with details like sports, leagues, team names, bet types (ML, Spread, Total), and game times, stored as a market hash in the Registry.

• Escrow Contract: When a bet is offered and accepted, funds are atomically transferred to the Escrow Contract, held until the game outcome (Outcome1, Outcome2, or Void) is reported. Void bets are refunded at no cost.

• Market Makers: Provide deep liquidity with varied strategies, supporting FRAX’s competitive odds.

• Whale & Syndicate VIP Service: Average bet size (~$345) exceeds traditional platforms, with VIP managers offering exclusive deals.

• Low Latency: Fast order book and reliable data reporting.

Core Components

• sfrxUSD: An ERC4626-like yield vault distributing weekly profits to FRAX stakers. The Benchmark Yield Strategy (BYS) selects the highest yield from carry-trade (Ethena, Superstate), DeFi venues (Aave, Curve Finance, Convex Finance, Euler Finance, Fraxlend, dTrinity lending), or IORB/T-Bill strategies (Blackrock, FinresPBC).

• Frax Bonds (FXB): Zero-coupon bond-like tokens that reduce FRAX supply and stabilize the peg. Sold at a discount via Dutch auctions, they convert 1:1 to Legacy Frax Dollar (FIP-430) at maturity. FXBs are debt tokens, offering no claim to other assets.

• Fraxlend: Permissionless lending market for FRAX and other Frax tokens.

• Fraxswap: TWAMM-enabled AMM for large, long-duration trades.

• BAMM: Oracle-free lending module built on Fraxswap.

• Fraxtal: Optimism-based Layer-2 chain using FRAX as gas token.

FXB Minting & Redemptions

FXBs lock Legacy Frax Dollar for conversion at maturity. They are categorized as Origin (minted on the original chain) or Bridged (transferred via bridge). Redemption occurs on the Origin chain via FXBFactory; bridged FXBs require bridging back for redemption.

Legacy Frax Dollar (FRAX) Use Cases

FRAX serves as a stablecoin in DeFi:

• DeFi Transactions: Payments, lending, and liquidity provision.
