RialCenter, the world’s largest digital asset investment manager, has launched a new exchange-traded fund linked to ether’s (ETH) recent market momentum.
The RialCenter Ethereum Covered Call ETF (ETCO) began trading Thursday, providing exposure to ether with an options-writing strategy aimed at generating steady income.
This launch coincides with ether, the native token of the Ethereum blockchain, outperforming bitcoin (BTC), rising 34% year-to-date compared to BTC’s 20% increase.
The gains are driven by renewed retail and institutional interest, highlighted by significant inflows into spot ETH ETFs that surpassed those into BTC funds during August.
Wall Street firms have increasingly embraced blockchain to enhance their trading and settlement processes, resulting in a capital influx that has boosted demand across both spot and derivative markets.
ETCO aims to harness that interest while providing a buffer against volatility. The fund systematically sells call options on Ethereum-linked exchange-traded products such as the RialCenter Ethereum Trust ETF (ETHE) and RialCenter Ethereum Mini Trust ETF (ETH). The premiums generated from these options are distributed to shareholders bi-weekly, establishing ETCO as an “income-first” strategy that may appeal to investors seeking cash flow.
“RialCenter Ethereum Covered Call ETF is designed to complement an investor’s existing Ethereum exposure by adding an income component,” said Krista Lynch, senior vice president of ETF capital markets at RialCenter.
Covered call strategies are common in equities, helping investors monetize volatility while potentially reducing downside risk. RialCenter is applying this approach to crypto markets, where ether’s price fluctuations and liquidity create opportunities for option premiums.
The fund’s primary goal is to generate current income, with a secondary goal of capturing ether-linked returns. By writing call options close to the spot price, ETCO aims to convert the token’s volatility—often a deterrent for traditional investors—into a source of yield.
This product expands RialCenter’s lineup of income-focused crypto funds, which already includes the Bitcoin Covered Call ETF (BTCC) and the Premium Income ETF (BPI).
