Binance Wallet launches Web3 API, supporting developers to programmatically access on-chain transactions and market data

According to the official announcement, Binance Wallet has launched the Web3 API, which is a comprehensive set of API endpoints that allows developers, institutions, and advanced on-chain traders to access on-chain trading and market data through a single integrated programming interface.

The API supports multiple chains (including Ethereum, BNB Smart Chain, Plasma, Arbitrum, Polygon, Base, Monad, Optimism, Linea, and Solana), providing real-time market data, aggregated exchange quotes, and on-chain trading execution capabilities.

Key features include: market data API (real-time token prices, K-line data), trading API (aggregated quotes, token exchanges, built-in MEV protection), non-custodial architecture (does not hold private keys, user local signing), and enterprise-level reliability.

Currently, there are zero service fees and zero slippage fees, with all price improvements returned to users. This API is suitable for developers building DApps, on-chain trading bots, and AI agents.
