Legacy FRAX Dollar is the original stablecoin of Frax Finance that transitioned from a fractional-algorithmic model to full 100% collateralization in February 2023. As of April 27, 2026, Legacy FRAX maintains approximately $273M market cap with 276M circulating supply (matching total supply, no dilution risk), trading near $1.00 with a stable peg. The protocol accelerates its transition to GENIUS Act-compliant frxUSD ($125M market cap, 125M circulating supply), which officially launched on Aave V4 on March 30, 2026, as a day-one default stablecoin in the Bluechip configuration. frxUSD serves as the base dollar pairing for onchain FX markets launched by Polygon, Curve, and Frax, supporting currency pairs including BRZ, IDRX, tGBP, AUDF, and KRWQ. The frxUSD/crvUSD PegKeeper pool on Curve reached $37M TVL with the highest gauge weight on the platform, while additional PegKeeper pools went live with OUSD (Origin Protocol) and tmvUSDC (Term Labs). FIP-443 authorized $27.5M in sfrxUSD deployments across Aave V4 hub-and-spoke architecture and Morpho curated vaults. FraxNet SaaS completed full documentation and API release for institutional white-label stablecoin infrastructure, validated by Sonic Labs (USSD) and supported by Fireblocks for institutional custody on Fraxtal L1. ATW Partners deployed $50M into frxUSD via BitGo custody backed by WisdomTree WTGXX tokenized Treasuries. Legacy FRAX remains fully collateralized through FinresPBC Treasury bills, Federal Reserve deposits, and AMO-managed crypto assets, but receives no new integrations.
Competitive Position
Legacy FRAX occupies a diminishing transitional position in the stablecoin market as Frax Finance accelerates its shift to frxUSD. As of April 27, 2026, Legacy FRAX maintains approximately $273M market cap with stable 276M circulating supply, trading near $1.00. In a stablecoin market dominated by USDC ($40B+), USDT ($150B+), and DAI ($5B+), Legacy FRAX is dwarfed by centralized competitors and increasingly overshadowed by frxUSD ($125M market cap, 125M supply). frxUSD"s competitive position strengthened significantly in Q1-Q2 2026: it officially launched on Aave V4 on March 30, 2026, as a day-one default stablecoin in the Bluechip configuration, becoming a core borrowable asset across next-generation DeFi lending. It serves as the base dollar pairing for onchain FX markets launched by Polygon, Curve, and Frax covering BRZ, IDRX, tGBP, AUDF, and KRWQ currency pairs. The frxUSD/crvUSD PegKeeper pool reached $37M TVL with Curve"s highest gauge weight, alongside new PegKeeper pools with OUSD (Origin Protocol) and tmvUSDC (Term Labs). ATW Partners deployed $50M into frxUSD with BitGo custody backed by WisdomTree WTGXX tokenized Treasuries, while Fireblocks added institutional custody support for Fraxtal L1. FraxNet SaaS completed full documentation and API release for white-label stablecoin infrastructure, validated by Sonic Labs (USSD) and KRWQ joining as GENIUS-compatible network partner. FIP-443 authorized $27.5M in sfrxUSD deployments across Aave V4 hub-and-spoke architecture and Morpho curated vaults. Distribution spans Aave V4, Aerodrome (Base), EtherFi credit cards, Scale.farm (Base), Tempo mainnet, Stake DAO vaults via Morpho, and Parallel Protocol pools on Avalanche. The GENIUS Act (signed July 2025, co-drafted by Sam Kazemian) drives frxUSD regulatory positioning, with Fraxtal mainnet frxUSD freezer upgrade progressing for compliance. Legacy FRAX still offers AMO yield strategies across Fraxlend, Curve, and Uniswap V3 with full collateralization, but receives no new integrations as protocol resources focus entirely on frxUSD ecosystem growth.

Serves as base dollar pairing for Polygon/Curve onchain FX markets covering 6+ currency pairs with $37M crvUSD PegKeeper pool (highest Curve gauge weight)
Legacy FRAX maintains its dollar peg near $1.00 with approximately $273M market cap and 276M circulating supply (no dilution risk), fully collateralized through FinresPBC Treasury bills, Federal Reserve deposits, and AMO-managed assets. The protocol transition to frxUSD accelerated with the official Aave V4 launch on March 30, 2026, as a day-one default stablecoin in the Bluechip configuration, expanding frxUSD to $125M market cap. Additional momentum includes onchain FX market integration (Polygon/Curve), the $37M crvUSD PegKeeper pool earning Curve"s highest gauge weight, ATW Partners $50M deployment via BitGo custody, Fireblocks institutional support for Fraxtal L1, and FraxNet SaaS completing full documentation and API release. Legacy FRAX remains functional within the Frax ecosystem with 100% collateralization, but new users should prioritize frxUSD for its institutional-grade integrations (Aave V4, Fireblocks, BitGo), regulatory alignment under the GENIUS Act, and active development focus. Legacy FRAX represents stable but transitional infrastructure with a clear sunset trajectory.
Institutional validation: ATW Partners deployed $50M into frxUSD via BitGo custody backed by WisdomTree WTGXX tokenized Treasuries, Fireblocks added institutional support for Fraxtal L1, Sonic Labs built USSD on frxUSD infrastructure, and KRWQ joined FraxNet as GENIUS-compatible network partner
4FraxNet SaaS completed full documentation and API release for white-label stablecoin infrastructure with yield forwarder contracts. Distribution spans Aave V4, Aerodrome (Base), EtherFi credit cards, Scale.farm (Base), Tempo mainnet, and Stake DAO curated vaults via Morpho
5Battle-tested through multiple market cycles since December 2020, maintains stable peg near $1.00 with 276M supply and $273M market cap. Active governance (FIP-442 legacy Convex exit, FIP-443 sfrxUSD strategies for Aave V4 and Morpho) manages orderly transition
Risks
5
1No guaranteed 1:1 frxUSD migration since FIP-430 (April 2025) ended direct conversion to separate balance sheets for regulatory compliance. Users must rely on secondary market swaps (Curve, Balancer, Uniswap) with potential slippage risk
2Accelerating capital migration to frxUSD, reinforced by Aave V4 official launch (March 30, 2026) as day-one default stablecoin, onchain FX market integration with Polygon/Curve, $37M PegKeeper pool TVL, Fireblocks institutional support, and FraxNet SaaS API completion, while Legacy FRAX receives no comparable new integrations
3Legacy infrastructure wind-down signals: FIP-442 introduced early exit for legacy Convex FRAX vaults at 4% fee, FIP-443 authorizes $27.5M sfrxUSD deployments across Aave V4 and Morpho (not Legacy FRAX), and completed FraxNet SaaS documentation all indicate protocol actively facilitating migration away from Legacy FRAX
4Smart contract complexity across multi-protocol ecosystem (AMO controllers, ERC-4626 vaults, cross-chain integrations on Fraxtal L2) with maintenance resources shifting to frxUSD development, FraxNet SaaS institutional adoption, and Aave V4 integration
5Custodial counterparty risk with enshrined custodians (FinresPBC holding Treasury bills, Lead Bank Kansas City) managing RWA collateral off-chain, though GENIUS Act mandates monthly reserve disclosures and 100% backing requirements
