1. A Market Maker Becomes a Fund Manager
GSR, which has spent more than a decade operating as one of crypto's largest market makers and OTC trading providers, has entered the asset management industry with the launch of its first exchange-traded fund. The GSR Crypto Core3 ETF, trading under the ticker BESO on Nasdaq, offers combined exposure to Bitcoin, Ether, and Solana through an actively managed structure that rebalances weekly using research-driven signals and is designed to capture staking rewards on eligible proof-of-stake assets. GSR CEO Xin Song described the launch as an extension of the firm's decade-long expertise in liquidity provision and market infrastructure into a format accessible to retail and institutional investors through standard brokerage accounts. Framework Digital Advisors serves as the fund's investment adviser, with GSR's capital markets capabilities underpinning the portfolio management approach.
2. What Makes BESO Structurally Distinct
The US crypto ETF market has, until now, been defined almost entirely by single-asset passive products — spot Bitcoin ETFs and spot Ethereum ETFs that track one asset at a fixed cost with no active allocation decisions. BESO breaks from that template in two specific ways. First, it combines three assets rather than one, framing the basket as a diversified representation of crypto's primary investment themes rather than a directional bet on a single coin. Second, it incorporates active management with weekly rebalancing, giving the portfolio team the ability to shift allocations among Bitcoin, Ether, and Solana based on market signals rather than maintaining fixed weights. The 1% annual management fee reflects those active management capabilities — higher than the near-zero fees charged by leading passive single-asset crypto ETFs but consistent with active ETF pricing conventions in traditional asset classes.
GSR describes itself as the issuer of the first actively managed multi-asset crypto ETF in the US to include staking capabilities, positioning BESO at the intersection of spot exposure and on-chain yield capture. At least 80% of the fund's assets will be invested in digital assets directly or through exchange-traded products, according to its SEC filing.
3. The Two-Theme Framework Behind the Asset Selection
The selection of Bitcoin, Ether, and Solana is grounded in a specific analytical framework rather than a top-three-by-market-cap approach. GSR frames the three assets as representing two distinct but complementary investment themes within crypto markets. Bitcoin occupies the macro asset role — a globally traded, institutionally held store of value whose price dynamics are increasingly shaped by ETF flows, corporate treasury allocation, and geopolitical demand. Ether and Solana occupy the blockchain platform role — layer-1 networks whose value is derived from the activity they support: stablecoins, tokenized assets, DeFi applications, and payments infrastructure. The two themes are structurally different in their return drivers and correlation profiles, providing a diversification rationale for combining them that goes beyond simple market-cap weighting.
Andy Baehr, GSR's Managing Director of Asset Management, articulated the product logic as addressing three questions: what to own, how to earn yield while holding, and how to be positioned as markets evolve. The staking yield capability on Ether and Solana — assets whose consensus mechanisms involve validators earning rewards for participating in network security — addresses the second of those questions in a way that single-asset Bitcoin ETFs cannot, since Bitcoin's proof-of-work mechanism has no equivalent staking yield component.
4. Staking Within an ETF: Opportunities and Risks
The inclusion of staking yield in an ETF wrapper is a feature that has gained regulatory acceptance in the US in 2026, following earlier debates about whether ETF structures could accommodate on-chain staking without creating regulatory complications around what constitutes an investment contract. BlackRock's IBIT, the largest Bitcoin ETF, has added staking capabilities for eligible assets, establishing a precedent that BESO is building on. For Ether and Solana, the annual staking yield — approximately 2.88% for ETH and higher for SOL depending on network conditions — provides an incremental return component that compounds over time and partially offsets the 1% management fee at current yield levels.
The fund's SEC filing discloses the material risks that accompany staking in this context. Staked assets may be subject to "slashing" — the network-imposed penalty for validator misbehavior — creating a scenario in which a portion of staked assets could be permanently destroyed if a validator acts incorrectly. Unbonding periods, during which staked assets are illiquid while awaiting release from the staking contract, can range from several days to several weeks depending on network conditions, creating a mismatch between the fund's daily liquidity obligations to ETF investors and the settlement timeline of its staked positions. These risks are real but manageable within a diversified fund structure where not all assets are staked simultaneously and liquidity buffers can be maintained in unstaked holdings.
5. GSR's Strategic Expansion Beyond Market Making
The BESO launch is part of a broader strategic evolution at GSR that has accelerated through 2026. In March, the firm acquired Autonomous and Architech to expand its token advisory and go-to-market services business. Earlier in April, it invested in Libeara, a tokenization platform backed by SC Ventures. The ETF launch represents a further diversification of GSR's revenue base — from trading and market making fees toward recurring asset management fees and the broader institutional relationships that come with operating registered investment products. The asset management expansion also gives GSR direct exposure to the retail investor demand for crypto products that has driven record inflows into IBIT and other US crypto ETFs, a market segment that pure market making operations do not capture.
GSR has spent more than a decade building liquidity infrastructure, OTC trading desks, and market making capabilities across crypto. The firm's argument for why that background is relevant to active ETF management — rather than being a separate competency entirely — is that understanding intra-asset and cross-asset crypto liquidity dynamics in real time is a meaningful edge in managing a portfolio that rebalances weekly and responds to market signals. Whether that edge translates into consistent outperformance against a simple equal-weighted benchmark will be the primary measure of the active management proposition over time.
6. The Broader US Crypto ETF Expansion
BESO arrives in a US crypto ETF market that has expanded rapidly since the January 2024 launch of spot Bitcoin ETFs and has been further broadened by spot Ethereum ETFs. The next phase of product development involves multi-asset funds, income-generating structures, and actively managed approaches — a category that regulators, ETF issuers, and investors have been working toward simultaneously. Other "crypto blue chip" basket proposals are in various stages of the regulatory pipeline, and BESO's launch as one of the first to receive approval and list establishes an early position in what is likely to become a competitive product category. The combination of Bitcoin's continued institutional adoption, Ethereum's integration into tokenized finance, and Solana's growth as a payments and consumer application platform makes the three-asset basket a coherent proposition for investors who want single-ticket crypto exposure without having to choose between the macro store-of-value thesis and the smart contract platform thesis.
