    BRAND ARCHITECTURE

    One company.
    One stablecoin.

    LYNXX is the company and technology platform. USDXX is its proposed digital dollar—the token you mint, hold, redeem and integrate.

    In short: USDXX is the digital dollar. Indexx Pay is where you buy and spend it. LYNXX is the company behind USDXX.

    THE COMPANY

    LYNXX

    LYNXX owns the technology, the intellectual property, and the licensing, banking and reserve relationships that let a regulated dollar stablecoin exist. It sets product strategy and operates USDXX end to end; a licensed partner acts as issuer of record.

    THE MARKET GAP

    Digital dollars are wanted.
    Trust and access aren’t even.

    Three gaps keep dollar stablecoins from serving global users well. USDXX is designed to close all three at once—not to reinvent the stablecoin.

    01

    Trust gap

    Holders need confidence that every token is redeemable, liquid and fully reserved.

    USDXXSegregated 1:1 reserves, a monthly independent attestation target, and public supply and coverage.

    02

    Distribution gap

    Exchanges, fintechs and merchants need reliable access across borders and blockchains.

    USDXXOne canonical asset identity, redemption and settlement APIs, and anchor-partner corridors.

    03

    Operating gap

    Issuers need compliance, treasury, security and customer operations that scale together.

    USDXXA complete operating system — reserves, redemption, controls and monitoring — not only a smart contract.

    BUILT FOR

    needs to settle.

    USDXX starts where it solves a measurable settlement problem—not everywhere at once.

    THE USDXX STANDARD

    Designed for trust.
    Engineered for movement.

    USDXX is built around the whole operating system—reserves, redemption, compliance, controls and a proof layer that lets a payment carry its purpose and conditions—not only the smart contract.

    01

    One identity. Every approved chain.

    USDXX uses one canonical asset identity mapped to verified chain deployments—never a reused legacy contract. Launch begins on a single chain, then expands under liquidity and operational controls.

    ↗
    02

    Proof before promises.

    Circulating supply, mint and burn activity, reserve coverage and attestation dates are designed to be visible in one place—so holders underwrite the reserve, not just the contract.

    ↗
    03

    Controls where they matter.

    Separated admin, minter and pauser roles, multisig administration, policy screening and an emergency pause protect every privileged operation. Minting is never separated from verified funds.

    ↗
    04

    AI assists—humans decide.

    AI supports fraud signals, reconciliation checks and treasury forecasting. It never moves reserves or changes supply on its own; authorized humans hold mint, freeze and redemption controls.

    RESERVE & REDEMPTION

    Every token,
    backed and redeemable.

    Trust is built through segregation, liquidity and proof—reserve assets are customer backing, not fundraising capital and not operating cash.

    REGULATION

    Compliance is the
    product—not a patch.

    USDXX follows the market into each jurisdiction it operates in, through a partner-led licensed structure—not a regulatory grey area.

    United States

    GENIUS Act

    Permitted issuer framework, 1:1 reserves, BSA / AML and lawful freeze capability.

    RECOMMENDED STRUCTURE

    A LYNXX technology & IP company, a licensed issuer partner, and regulated reserve, banking and distribution partners. An offshore holding company may support ownership or tax planning, but it does not remove licensing obligations where USDXX is issued or offered. Final structure is subject to legal counsel.

    USDXX EARN · 8% · 10% · 12% APY

    Put your USDXX to work.
    Earn up to 12% APY.

    Commit USDXX for 3, 6 or 12 months and earn 8%, 10% or 12% APY. USDXX Earn is a separate, opt-in program with its own terms, risk disclosures and eligibility — holding USDXX on its own stays 1:1 and redeemable. Earnings are funded separately from, and never paid out of, the USDXX redemption reserve.

    Proposed rates. Illustrative calculation assuming constant APY, reinvestment and no fees. APY is an annual rate — 8% APY does not mean earning 8% in three months. USDXX Earn launches separately from the stablecoin, after its funding source and independent legal, tax and risk review are approved. Not a guaranteed return, deposit rate, or live offer.

    CHAIN-NEUTRAL BY DESIGN

    One USDXX.
    Wherever value moves.

    Authorized deployments share one economic identity and reconcile to one global supply ledger. USDXX launches on a single chain, then expands only where liquidity and controls justify it.

    FAQ

    Questions,
    answered plainly.

    Is USDXX live?

    No. USDXX is in a controlled pilot on testnet. There is no mainnet issuance, no live minting or redemption, and no customer funds are accepted. Every figure shown on this site is a placeholder or a management target pending partner and legal validation.

    What backs USDXX?

    The design target is at least 1:1 backing with high-quality liquid reserves: cash and bank deposits, short-term U.S. Treasuries, and overnight Treasury repo or government money market funds. Reserves are held segregated as customer backing — they are not operating cash and not fundraising capital. No portion of the redemption reserve is held in Bitcoin or other volatile crypto.

    Can I redeem USDXX for dollars?

    At launch, direct mint and redemption run through a licensed issuer partner for approved (KYC/KYB) participants, with a target service level of same-day to next-day (T+0 / T+1). Ordinary wallet-to-wallet transfers happen on-chain and only cost network gas.

    How much can I earn with USDXX Earn?

    USDXX Earn proposes 8% APY for a 3-month commitment, 10% for 6 months and 12% for 12 months. On 1,000 USDXX that is about 19.43, 48.81 or 120.00 USDXX over the term, assuming constant APY, reinvestment and no fees. Rates are proposed, not live, and depend on final terms, eligibility and jurisdiction.

    Does holding USDXX pay interest?

    No. Holding USDXX pays no yield — it is a payment and settlement asset that stays 1:1 and redeemable. "USDXX Earn" is a separate, opt-in program with its own terms, eligibility and risk disclosures; Earn balances are not part of the USDXX redemption reserve.

    How is USDXX different from USDT or USDC?

    The structure is the same: a company issues and operates a dollar stablecoin. Tether issues USDT; Circle issues USDC; USDXX is issued through a licensed partner and operated by LYNXX. What differs is focus — USDXX does not try to match incumbent scale on day one. It aims for a defensible distribution wedge in selected exchange, payment and crypto-native corridors, with a monthly independent attestation target and public reserve reporting.

    Is USDXX the same as LYNXX?

    No — they are two things at two layers. LYNXX is the company: it holds the technology, the intellectual property and the licensing and reserve partnerships. USDXX is the stablecoin the company brings to market — the token you mint, hold, redeem and integrate. You hold "USDXX" the same way you would hold "USDT," and most users never need to say "LYNXX" out loud. The full name is "USDXX by LYNXX."

    Do I need an account or password?

    No. Your browser wallet is your access — USDXX never receives your seed phrase or private keys. Identity verification (KYC/KYB) applies only to participants who mint or redeem directly with the issuer.

    Which blockchains will USDXX support?

    One canonical asset identity, one launch chain first. Additional chains are added only where liquidity and operational controls justify them, and each deployment reconciles to a single global supply ledger.

    Is my transaction data public?

    The public chain is designed to show only what proves the system is sound — total supply, mint and burn, reserve coverage, attestations. Identities, amounts, balances and wallet relationships are not published. A 72-hour "Privacy Window" lets you share a verifiable receipt with a merchant or auditor; access then expires.

    Who operates USDXX?

    USDXX is the stablecoin from LYNXX. LYNXX owns the technology, the intellectual property and the product; issuance of record runs through a licensed issuer partner, alongside regulated reserve, banking, custody and attestation partners. Equity capital funds the company; customer reserve assets back the token, held separately.

    Is USDXX an investment?

    No. USDXX targets a stable value of US$1.00 and is meant for payments and settlement, not appreciation. Company equity and token holdings are entirely separate. Nothing on this site is an offer, a solicitation, or investment, legal or tax advice.

    Full risk factors and terms are in the Legal & Risk Disclosure.
