Layer‑2 scaling is the bridge to mainstream crypto. By bundling many on‑chain actions into a single transaction, roll‑ups cut fees, boost speed, and keep security. Projects like Optimism, Arbitrum, and zk‑Rollups now host DeFi, NFT, and GameFi ops that feel like app‑store interactions. Yet the promise hinges on user‑friendly wallets, reliable bridges, and cross‑chain composability. As these hurdles clear, mass adoption moves from niche hobby to everyday utility.
