Canary Marinade Solana ETF (SOLC)

Product structure. SOLC is an exchange-traded product that holds SOL, the native token of the Solana blockchain. Unlike some competing products, it commits to passing 100 percent of staking rewards through to shareholders — no fee haircut on the yield itself, only on the AUM. Launched in November 2025, the fund staked all its holdings through Marinade Select, a staking infrastructure service run by Marinade Labs.

The staking mechanism. Solana uses proof-of-stake consensus: validators stake SOL as collateral and earn new tokens if they validate blocks correctly. SOLC pools investor capital into Marinade’s validator set, capturing rewards without requiring individual investors to run validator hardware. Historically, Solana staking yields have ranged between 5 and 8 percent, though no yield is guaranteed and can decline if validator participation increases or the protocol changes. Because Solana operates with higher validator throughput than competing staking networks, its yields tend to be lower than some alternatives, but the staking is more straightforward operationally.

The custody story. Solana staking is custodially complex: it requires private keys to sign transactions. SOLC uses BitGo for custody and Marinade Select for on-chain staking operations. Both are institution-grade services, but institutional staking in Solana is a newer capability than in Ethereum or Avalanche, and operational complexity remains higher. BitGo custody is standard across the industry. Marinade Select is operated by Marinade Labs, which also maintains Marinade Finance, the largest and most-used liquid staking protocol on Solana. That duopoly — custody from BitGo, staking from Marinade — is the sum of Canary’s operational moat. Any other asset manager could contract with the same two providers and launch an identical product.

Competitive position. Canary Capital is less well-known than Grayscale in institutional cryptocurrency markets, which is a friction point for institutional adoption. Grayscale, by contrast, has operated cryptocurrency trusts since 2013 and is an established platform for institutional access to digital assets. Canary has no defensible advantage in staking Solana; it relies on Marinade’s infrastructure, which is available to any other provider. If Solana’s staking yields remain attractive and other fund sponsors enter the market, SOLC will face direct competition on fees and service quality. That competition should tighten fees and drive commoditization.

On-chain risks. Solana’s network has experienced consensus failures and temporary outages in the past, including a chain halt in November 2023. If SOLC is staked and the network halts, those tokens are frozen until consensus resumes. If the network suffers a permanent failure, SOL would become worthless. Solana also operates with high transaction throughput, which creates engineering complexity and attack surface; the network has suffered validator attacks and client software bugs. For a staking ETF, these risks are amplified because the fund is not just exposed to price risk but also locked into on-chain operations that depend on the network’s operational integrity.

Fee structure and regulatory classification

Unlike traditional mutual funds, SOLC operates as an exchange-traded product registered under SEC securities rules but not registered as a fund under the Investment Company Act. This means the fund lacks some investor protections afforded to registered funds, though it is still subject to audit and reporting requirements. The fee structure matters enormously: Canary’s marketing emphasizes the full passthrough of staking rewards, but investors pay a management fee on assets (typically around 0.25 to 0.50 percent annually for cryptocurrency ETPs). That fee is deducted from NAV, so while 100 percent of on-chain staking rewards flow to the fund, the AUM fee reduces the net yield investors realize. If Solana’s staking yield falls to 5 percent and SOLC’s fee is 0.35 percent, the net yield to the investor is 4.65 percent.

Tracking and research

SOLC’s net asset value should track SOL’s spot price plus the staking yield, minus fees. Compare to SOL’s price on major exchanges (Binance, Coinbase) and to the Marinade APY posted on-chain. Watch Canary’s filings for assets under management and any changes to the staking arrangement or fee structure. Monitor Solana Foundation announcements on protocol upgrades and validator ecosystem health, since validator economics and inflation schedule directly determine the staking yield available to the fund. SOLC is a very new product; regulatory and operational risk is higher than with longer-established funds. For institutional investors, understand the custody arrangement and whether SOL held in the fund is subject to lending or other uses that might affect performance. Verify that staking is truly 100 percent — if Canary retains any rewards or charges a performance fee on top of the AUM fee, the effective yield is lower than advertised.
