How to Build Fault-Tolerant Blockchain RPC Infrastructure

I've spent enough time debugging production blockchain infrastructure to see a pattern. Teams spend months auditing their intelligent contracts, and then treat their RPC layer as an afterthought, a single endpoint pointed at Infura or Alchemy with no fallback plan. That works okay at ten requests per second. It crumbles the first time a mint goes viral or a cascade of liquidations happens during a volatile hour.

This is not a critique. It's simply the natural default focus for most teams. Everyone knows exploits are expensive, so contract code is audited. Infrastructure is only noticed when it fails in front of users.

Why RPC Infrastructure Is the Part Nobody Budgets For

Between every user action and the chain itself sits an RPC node. Every wallet connection, every read call, every transaction submission goes through it. When it slows down*,* the application seems broken, even if the contracts are fine.
