What Tools Are Needed to Build a Decentralized Application?

Most decentralized applications require several technical components:

• A blockchain or execution network
• Smart contracts
• RPC or node access
• Wallet integration
• Blockchain data and indexing
• Testing and simulation
• Application monitoring
• Storage
• Identity and authentication
• Frontend and backend SDKs

Some development platforms specialize in one component. Tenderly focuses on simulation, Moralis focuses on data and OpenZeppelin focuses on smart contract development.
