The @base @solana bridge is crucial for payments. Solana is the cheapest mainstream L1 for payments, has massive stablecoin velocity (8.2x supply growth YoY vs 2.5x for Ethereum), and can handle retail-scale throughput. Base is the most compliant U.S.-aligned L2, has merchant tooling (Stripe, Shopify, Coinbase), and has smart wallets, gas abstraction, and session keys. Base <-> Solana means that a merchant accepting USDC via Base can settle back into Solana instantly, while users with Solana wallets can pay in Base apps without friction. This is essentially a marriage between scale and compliance + commerce that is a meaningful step toward a unified onchain economy.
