The article explores the necessity of RPC nodes in decentralized finance (DeFi) applications, specifically comparing Ethereum, Solana, and Polygon based on performance and cost. It discusses the role of RPC nodes as intermediaries that enable dApps to interact with blockchain networks without operating a full node. Different RPC service providers like GetBlock, Infura, Alchemy, and QuickNode are also evaluated regarding their suitability for various DeFi scenarios such as trading, yield farming, and lending. Practical guidance is offered to assist developers in selecting the best node for their use cases.
RPC nodes are essential for decentralized applications as they serve as the intermediary between the dApp and the blockchain, allowing for efficient data retrieval and transaction execution.
Choosing the right RPC service provider can significantly affect your DeFi application's performance. Each offers unique advantages in speed, pricing, and ease of use, which must align with your specific use case.
