Skill is based on TronWeb v6.2.0, generated at 2026-02-25.
TronWeb is the official JavaScript/TypeScript SDK for the TRON network. It wraps the TRON HTTP API and provides a consistent API for accounts, blocks, transactions, smart contracts, and events. Use it in Node.js or the browser to build DApps, sign and broadcast transactions, and call contracts.
