Binance Wallet unveils Web3 API for multi-chain access

Binance Wallet’s new Web3 API enables seamless access to on-chain data, real-time market info, and multi-chain trading, simplifying DeFi integration for developers and traders.

Binance Wallet has introduced a Web3 API tailored for developers, institutions, and advanced traders. This API streamlines programmatic access to on-chain transaction data and real-time market information through a single integration point. Supporting multiple EVM-compatible networks—including Ethereum, BNB Smart Chain, Arbitrum, and Polygon—as well as Solana, the API is designed for broad compatibility, with plans to add more chains in the future. Key features include a Market Data API for real-time token prices, candlestick charts, and price change rankings, and a Trading API that aggregates swap quotes, executes token swaps, and broadcasts on-chain transactions. Additional highlights are built-in MEV protection, a non-custodial model, and zero service fees for a limited period. By consolidating data and trading access across blockchains, the API reduces development complexity and enhances opportunities for DeFi applications. It is compatible with standard Web3 connection methods, easing integration for existing DeFi platforms.
