Focus on learning web3 libraries like web3.js, ethers.js, and SDKs such as Alchemy, Moralis, and Infura. These tools enable interaction with blockchain networks, smart contract execution, and wallet management.
Learn programming languages such as Python, JavaScript/TypeScript, Rust, or Go, commonly used in blockchain development. Study blockchain basics, including transactions, smart contracts, and decentralized systems. Start with platforms like Ethereum, Binance Smart Chain, or Solana.
Master RESTful and GraphQL APIs to query blockchain data efficiently. Use tools like The Graph for indexing data and JSON-RPC to interact with blockchain nodes.
Build simple projects like token transfer APIs or wallet balance fetchers. Read official documentation from blockchain protocols and contribute to their developer forums for practical knowledge.
This approach ensures a smooth transition from ERP API development to blockchain API development while building essential expertise.
