Market context
DeFiLlamaSkip this Frax Finance explainer if you wanted a first wallet setup or a CEX account. It covers how the protocol works and who it is not for. How-tos and comparisons are linked where they exist.
Frax Finance pioneered the fractional-algorithmic stablecoin model in 2020 and has since evolved into one of DeFi's broadest protocol families. FRAX v3 is fully collateral-backed; frxUSD extends the dollar product line; sFRAX pays stablecoin savings rate; frxETH/sfrxETH compete in liquid staking; Fraxlend provides isolated lending; Fraxtal is an OP Stack L2 with FRAX gas.
Resupply Finance accepts Fraxlend frxUSD lending positions alongside Curve Lend crvUSD — tying Frax directly into the Convex–Yearn stablecoin flywheel.
Users deposit frxUSD into Fraxlend markets and receive LP tokens representing the lending position. Those tokens carry ongoing yield from borrowers. Depositing them into Resupply allows minting reUSD while yield continues — with borrow priced below collateral returns.
This gives Frax users a capital-efficiency path unavailable through standard CDPs: liquidity without sacrificing the Fraxlend APY stack.
Fraxtal hosts native FRAX, frxETH, and Frax protocols with low fees. Flox rewards FXS to active users and builders. Cross-chain deployments on Arbitrum, Optimism, and Polygon extend Frax liquidity beyond mainnet.
Convex's cvxFXS integration means Frax gauge emissions participate in the same vlCVX bribery market as Curve — deepening Frax–Convex alignment.
