Polygon has built the most extensive zk‑rollup ecosystem in the space, but the real advantage is network effects. When you have multiple chains that share the same security, the same developer tooling, and the same liquidity pools, you get something that feels like a single chain without the scalability bottlenecks. The challenge now isn’t technology; it’s convincing users that “Polygon” is the brand they trust, regardless of which specific rollup they’re on. Aggregation is a UX win, but it’s also a marketing win. The hardest part of any ecosystem is keeping the user experience simple, and this vault nails why that matters.
