Solana's SOL token surged 5.44% to $138.56, driven by increased activity on the x402 protocol, which recorded over 500,000 transactions and $100,000 in volume, reflecting a 500% weekly growth. This surge coincides with a new proposal, SIMD-0411, which suggests doubling the annual inflation rate to 30% to speed up deflation. The proposal aims to achieve a 1.5% final inflation target by 2029, three years earlier than planned, and reduce the supply by 22.3 million SOL.
