Layer‑2 isn’t just a tech tweak—it’s the bridge to everyday use. By rolling transactions off‑chain and settling on‑main, solutions like Optimistic Rollups, zk‑Rollups, and sidechains slash fees, boost speed, and keep decentralization. As developers layer these over Ethereum, Bitcoin, and others, the barrier to mass adoption drops, turning wallets into real‑world commerce tools.
