RPC Providers as Replaceable Access Layer
Auston Bunsen, Co-Founder of QuickNode, on the infrastructure of multi-chain
The key point is that node providers sit in the access layer, not the asset layer. A dapp usually keeps its real logic in onchain smart contracts, while the frontend can be repointed to a different RPC endpoint with a small config change. That makes QuickNode, Alchemy, and Infura important for speed and convenience, but weaker as hard choke points than AWS would be for a normal web app.

Ethereum apps talk to nodes through standard JSON-RPC methods, and common JavaScript libraries already support many providers. In practice, that means a team can swap Alchemy for Infura, QuickNode, or a self run node without rewriting the whole app, unless it depends on a provider specific API.
-
The strongest version of this resilience shows up when the frontend is also decentralized. Uniswap moved its interface onto IPFS, where the same app can be fetched through gateways or IPNS and still point at the same onchain contracts. If one host or gateway disappears, the contracts and interface can still be reached another way.
-
The real lock in battle is higher up the stack. Basic RPC is portable, but custom indexed APIs, wallet balance endpoints, NFT ownership lookups, and relay tools are where switching gets harder. That is why infrastructure companies race to add peripheral APIs, not just raw node access.
This market keeps moving toward modular redundancy. Core contracts stay onchain, frontends move toward IPFS style hosting, and RPC access becomes easier to route across multiple providers at once. The winning infrastructure companies will be the ones that pair commodity node access with proprietary convenience features, while developers design around the assumption that any single provider can be replaced.
