Multicoin Capital, a blockchain-focused investment firm, has pledged to double every Solana (SOL) donation made to the Sentinel Action Fund super PAC until July 14. The fund supports four pro-crypto Republican Senate candidates: Sam Brown in Nevada, David McCormick in Pennsylvania, Bernie Moreno in Ohio, and Tim Sheehy in Montana. All candidates have received A ratings from the Stand With Crypto organization. The Sentinel Action Fund, founded in 2022, spent over $13 million in the last election cycle, supporting and opposing various candidates based on their stance on cryptocurrency.
