Top asset manager Franklin Templeton has filed to offer a new exchange-traded fund (ETF) that, if approved, would give investors exposure to a basket of crypto funds.

The Franklin Crypto Index ETF, under the ticker EZPZ, would give exposure to digital assets included in the CF Institutional Digital Asset Index—an index from CF Benchmarks, which provides data to firms on cryptocurrencies.

It would initially hold Bitcoin and Ethereum , a Friday filing with the Securities and Exchange Commission (SEC) read .

Coinbase, America's biggest crypto exchange, would be the custodian for the proposed fund. Coinbase already stores digital assets for other top fund managers that have released crypto ETFs.

Franklin Templeton is one of many high-profile Wall Street firms that launched a spot Bitcoin ETF and later an Ethereum ETF this year.

Both funds give investors exposure to the two biggest cryptocurrencies by market cap. The SEC was reluctant to approve the crypto products—which give investors the ability to invest in digital assets via shares that trade on a stock exchange—but eventually green lighted the funds.

Franklin Templeton also this week announced that its Nasdaq-listed OnChain U.S. Government Money Fund, FOBXX, was accessible on the Arbitrum network.

Arbitrum is a popular scaling solution for Ethereum that aims to speed up transactions on the second-biggest crypto network.
