You can connect your app to Ethereum and other EVM blockchains using viem. This tool is built for TypeScript and JavaScript developers. It helps you read blockchain data, send transactions, and interact with smart contracts.
For React and Next.js apps, you can use wagmi. It is built on top of viem and provides ready-to-use hooks. The skill also shows you how to set up real-time event monitoring with webSocket transport.
Security is important. The skill includes rules to validate user inputs. For example, it checks Ethereum addresses and makes sure private keys are never hardcoded. This keeps your app safe.
