That\u2019s the digital doorway between your app and the blockchain. Through RPC, you can check balances, send transactions, and talk to smart contracts.<\/p>\n\n\n\n<p>Now, you <em>could<\/em> try running your own Polygon node\u2026 but trust me, it\u2019s expensive, time-consuming, and requires constant babysitting.
