Introduction

QQQX is a tokenized tracker certificate that brings the Invesco QQQ Trust — one of the world's most prominent tech-focused ETFs — directly onto blockchain rails. Issued under the xStocks platform by Backed Finance, it allows eligible crypto users to gain regulatory-compliant exposure to the Nasdaq-100 Index without leaving the on-chain ecosystem.

Each QQQX token is fully backed 1:1 by actual shares of the underlying ETF, held with licensed, third-party custodians. It trades on both Solana and Arbitrum, making it composable with the wider DeFi landscape.

History & Background

Backed Finance launched the xStocks product line to bridge traditional equities and decentralized finance. QQQX — tracking the Invesco QQQ Trust — was among the flagship products in this lineup.

In late 2025, Kraken acquired Backed Assets (JE) Limited, consolidating the xStocks infrastructure under one of crypto's most established exchanges. The xStocks platform has since grown to process billions in transaction volume and integrate with over 50 partner venues.

How Nasdaq tokenized stock (xStock) Works

QQQX follows a mint-and-custody model. When new tokens are issued, the underlying QQQ ETF shares are purchased on traditional markets and deposited with a regulated custodian such as Clearstream Banking or InCore Bank. A corresponding QQQX token is then minted on-chain.

Price alignment is maintained through an arbitrage mechanism: if QQQX's on-chain price deviates from the ETF's market price, market makers are incentivized to mint or redeem tokens to close the gap — similar to how stablecoins maintain their pegs.

Tokens can be freely transferred between wallets and moved cross-chain via Chainlink's CCIP infrastructure.

Tokenomics

QQQX is a demand-driven, fully collateralized token. New tokens are only minted when underlying ETF shares are purchased and deposited with a custodian, and tokens are burned upon redemption. This elastic supply model means the token count always reflects actual custody holdings.

The product currently charges no ongoing management fee at the token level, though a small annual fee may be introduced in the future to cover operational costs. Token holders gain economic exposure to QQQ price performance but do not receive voting rights or traditional dividend distributions.

Ecosystem & Use Cases

QQQX integrates with the broader DeFi ecosystem across Solana and Arbitrum. Holders can:

  • Trade QQQX against USDC or SOL on supported DEXs, 24/7
  • Use as collateral in DeFi lending protocols
  • Supply liquidity to yield-generating pools
  • Self-custody tokens in any compatible crypto wallet

The xStocks Alliance connects partner chains and trading venues, and QQQX is listed on major centralized exchanges including Bybit and Kraken alongside decentralized venues.

Team, Governance & Community

QQQX is issued by Backed Assets (JE) Limited, a Jersey-registered company and now a subsidiary of Kraken (Payward). The regulated legal framework is anchored under a Liechtenstein FMA-approved prospectus.

The broader xStocks community engages via the official Telegram and Twitter channels (@xStocksFi). Governance over the product sits with Backed/Kraken rather than a decentralized DAO, keeping compliance and custody decisions within a regulated entity.

Long-Term Vision

QQQX sits at the frontier of the real-world asset (RWA) tokenization movement. The xStocks platform aims to become the standard rail for tokenized equities globally, expanding the range of assets, supported chains, and DeFi integrations over time.

As regulatory clarity improves and institutional adoption grows, products like QQQX are positioned to make traditional equity markets accessible to anyone with a crypto wallet — a foundational step toward a fully on-chain financial system.
