# Web3 Pro
A practical playbook for building decentralized apps (dApps) on EVM-compatible chains: connecting wallets, reading and writing contract state, estimating gas, listening to events, and handling multiple networks — from any JavaScript/TypeScript frontend.
## Overview
A dApp frontend talks to a blockchain through an RPC endpoint using a wallet as the user's signing device. The mental model has three layers:
1. **Provider** — read-only connection to a chain (RPC URL + chain ID).
2. **Signer** — a wallet account authorized to sign transactions and messages.
3. **Contract** — an ABI plus address that turns blockchain state into typed function calls.
Most production bugs come from confusing these layers: doing reads through a signer (slow, prompts the user), sending writes through a provider (impossible), or assuming the user is on the right chain.
