Franklin Templeton’s USPX ETF is no longer limited to brokerage accounts and traditional exchanges. Through a new listing on Mantle, the asset manager’s exposure is now accessible as a tokenized representation on an Ethereum layer-2 network, as announced in the original report. The listing, conducted via the xStocks platform under the ticker USPXx, marks one of the first examples of a major traditional ETF moving on-chain via an Ethereum L2 positioned specifically for institutional distribution.
Mantle has carved out a niche as a network that bridges the gap between traditional capital markets and on-chain liquidity, rather than competing as a one-size-fits-all package. The decision to host a Franklin Templeton product strengthens that identity. For xStocks, which specializes in tokenized stocks and funds, bringing an ETF from a well-known issuer to Mantle is proof that regulated financial products can sit on public blockchain infrastructure without sacrificing compliance or investor familiarity. This move comes at a time when tokenization volumes are accelerating. Just weeks ago, the tokenization of real assets crossed the $20 billion mark on-chain, with major institutions settling live trades against tokenized Treasuries.
Why a Layer-2 Play is Important
Ethereum Mainnet remains the most secure and decentralized smart contract platform, but gas fees have long made frequent trading or exposure to small positions in tokenized funds impractical. Layer-2 rollups like Mantle solve that by compressing transactions and settling batches on Ethereum, driving down costs while maintaining underlying security guarantees. That fee structure makes on-chain ETFs viable for a wider range of users, not just whales. Mantle’s approach is specifically tailored to use cases at the institutional and distribution levels: the chain offers a proprietary return on bridged assets and an ecosystem fund designed to strengthen liquidity for high-quality RWA products.
The USPXx listing shows that ETF issuers are no longer waiting for perfect regulation. Instead, they work with a crypto-native infrastructure to make existing fund exposure tradable on-chain under existing frameworks. Franklin Templeton is not new to digital assets: the company runs a spot Bitcoin ETF and has explored tokenized money market funds. Expanding that strategy to an equity or commingled ETF via an Ethereum L2 indicates that institutional comfort with public blockchains is rapidly maturing.
What is still unclear
Although the listing is a milestone, a number of uncertainties remain. The liquidity depth for tokenized ETF shares is still small compared to centralized exchange and broker order books. The on-chain version of USPX could trade at a premium or discount to net asset value if enough arbitrageurs don’t intervene early. Mantle and xStocks will have to demonstrate that market makers can support tight spreads, or the product risks becoming a novelty rather than a liquid alternative.
The regulatory treatment of tokenized funds is also in a gray zone. The USPXx token likely represents a claim to beneficial ownership of the underlying ETF, structured to comply with the securities laws in the jurisdictions where it is offered. How regulators view secondary trading of that token in decentralized locations or via permissionless wallets is still being tested. The recent backlash from banking interests against crypto legislation, as seen in the Senate, underlines that the path for on-chain financial products is not yet set.
For Mantle, the timing works in his favor. As TradFi asset managers look for scalable on-chain distribution, networks that can prove low-cost, secure, and institutionally friendly infrastructure will likely capture early RWA flows. The USPXx list is not just a product launch; it’s a safe bet that the next wave of ETF distribution will be via Ethereum rollups, and not just traditional platforms.
