Introducing: Substreams Foundational Stores ✨ Foundational Stores help developers scale their projects by fetching onchain data from preindexed stores when streaming from the blockchain. Doing this typically requires slow and costly RPC calls to redundant datasets or local data caches. It’s tedious, expensive, and slows down the fun of innovating. Why it matters: ✅ Deterministic data access (no multiple eth_calls) ✅ Faster indexing + lower latency ✅ Major reduction in development time Perfect for DeFi protocols, wallets, and portfolio trackers.
