Grayscale has announced a temporary waiver of sponsor fees and a reduction in staking-related fees for its Grayscale Solana Trust ETF (GSOL). This waiver will last for up to three months or until the fund's assets under management (AUM) reach $1 billion, whichever occurs first. The fund currently has up to 100% of its SOL holdings pledged, offering a staking reward rate of 7.23%. The fee waiver is applicable to both new and existing investors in the GSOL, aiming to attract more interest and investment into the fund. This move comes as Grayscale seeks to enhance the appeal of its Solana ETF by reducing costs for investors while maintaining competitive staking rewards.
