Introduction

Coinbase xStock (COINx) is a tokenized representation of Coinbase Global (COIN) stock, issued by Backed Finance through its xStocks product line. It allows crypto-native users to gain price exposure to COIN shares without opening a traditional brokerage account.

COINx sits at the intersection of real-world assets (RWA) and decentralized finance, bringing equity market exposure on-chain in a composable, borderless format.

History & Background

COINx was created by Backed Finance, a Swiss firm specializing in blockchain-native financial instruments. It is part of the broader xStocks suite, which covers more than 57 US stocks and ETFs.

The xStocks platform reported over $300 million in on-chain transaction volume, reflecting significant early traction in the tokenized equity space. The product is designed for non-US investors who face geographic barriers to US equity markets.

How Coinbase xStock Works

COINx is structured as a tracker certificate. Each token is backed 1:1 by actual Coinbase Global shares held in custody by a regulated third-party institution. When a user acquires COINx, the custodian holds the corresponding real shares in reserve.

The token is issued as both a Solana SPL token and an ERC-20 token, covering multiple blockchains including Ethereum, Arbitrum, and BNB Smart Chain. This multi-chain design maximizes reach across wallets, DEXes, and CEXes.

Importantly, COINx does not confer stock ownership rights, voting rights, or dividend entitlements. It is purely a price-tracking instrument.

Tokenomics

COINx is a demand-driven token — new tokens are minted only when backed by real shares, and redeemed when those shares are withdrawn. This elastic supply model keeps the token supply aligned with actual custody holdings at all times.

The token's value is designed to mirror the Coinbase Global (COIN) share price on public markets, making its economic model straightforward: no inflationary rewards, no staking emissions.

Ecosystem & Use Cases

• Price exposure: Track the performance of COIN shares from a crypto wallet
• DeFi collateral: Deposit COINx on Kamino Finance (Solana) to borrow stablecoins
• Portfolio diversification: Add equity-like exposure to a crypto-native portfolio
• Cross-platform trading: Trade on CEXes like Gate.io and LBank, or on DEXes

Team, Governance & Community

COINx is governed and maintained by Backed Finance, which manages the custody, compliance, and issuance pipeline. Backed operates under EU regulatory frameworks, providing a layer of institutional oversight for the product.

The xStocks community is coordinated through the xStocks Alliance, a network focused on growing adoption of tokenized equities across both CeFi and DeFi ecosystems.

Advantages

• 1:1 backing ensures price fidelity with the underlying COIN stock
• Multi-chain availability on Solana, Ethereum, Arbitrum, and BNB Smart Chain
• DeFi composability allows COINx to function like any standard token within DeFi protocols
• No brokerage required — accessible to global users via crypto exchanges
• EU-compliant structure provides regulatory assurance for eligible investors
• Fractional access starting as low as $1 lowers the entry barrier

Risks & Challenges

• No ownership rights — holders do not receive dividends or voting rights from Coinbase Global
• Custodial risk — reliance on a third-party custodian introduces counterparty exposure
• Geographic restrictions — not available to US-based users
• Regulatory evolution — tokenized securities face an evolving and uncertain regulatory landscape
• Liquidity risk — on-chain liquidity may not always reflect traditional equity market depth

Long-Term Vision

COINx represents a building block in the broader movement to bring traditional capital markets on-chain. Backed Finance's vision is to modernize equity access — removing brokers, borders, and limitations — by making real-world assets composable within the global DeFi ecosystem.

As tokenized RWAs gain regulatory clarity and institutional adoption, products like COINx are positioned to become a standard tool for global investors seeking 24/7, borderless access to US equity markets.
