Crypto trading firm and market maker GSR has launched its first exchange traded fund, the GSR Crypto Core3 ETF, giving investors exposure to Bitcoin, Ether, and Solana.
The fund, which trades on Nasdaq under the ticker BESO, uses an actively managed structure, includes staking rewards, and carries a 1.00% management fee, marking GSR’s expansion into the fast growing U.S. digital asset fund market.
The new product marks a notable step for GSR, which has spent years operating as a crypto market maker and liquidity provider and is now pushing further into asset management.
Framework Digital Advisors is serving as the fund’s investment adviser, while GSR is positioning the ETF as a bridge between traditional finance demand and crypto native market expertise.
Core3 allocates across Bitcoin, Ether, and Solana and rebalances weekly using research driven signals aimed at improving returns over time. GSR said the strategy is built around two of the market’s biggest themes, Bitcoin’s role as a macro asset and the continued growth of blockchain networks such as Ethereum and Solana, which support use cases including stablecoins and tokenization.
The launch also reflects how quickly the U.S. crypto ETF market is broadening. GSR’s filing for Core3 had already been part of a wider pipeline of crypto fund proposals that moved beyond single token exposure and into baskets, staking, and active strategies. That expansion accelerated after rule changes in 2025 opened a faster path for plain vanilla crypto exchange traded products, helping fuel a wave of new listings and copycat filings.
Earlier U.S. listed products tied to Solana introduced regulated fund structures that pass through staking rewards, and later market commentary pointed to regulatory clarification around protocol staking as a major catalyst for ETF innovation. BESO now takes that trend a step further by combining staking with a multi asset portfolio and active allocation inside a single listed vehicle.
