Binance Web3 API gives developers, institutions, and advanced on-chain traders one integration for trading, market data, and wallet tools.
Binance Wallet said the new product offers a single set of API endpoints for programmatic access to on-chain functions. The company said the launch expands its Web3 setup beyond retail users. It is targeting builders of DApps, trading bots, portfolio tools, and AI agent workflows that need on-chain execution.
Binance Web3 API Core Features
The suite has three main parts. First, the Market Data API provides real-time token prices, candlestick data, and lists of top gainers and losers across supported chains. Meanwhile, the Trading API pulls swap quotes from several vendors, carries out token swaps on-chain, and includes built-in MEV protection.
Binance said the API supports major EVM-compatible networks. These include Ethereum, BNB Smart Chain, Arbitrum, Polygon, Base, Optimism, and Monad. It also supports Solana. Additionally, Binance said more chains are in the pipeline.
Non-Custodial Design and Fee Waiver
Binance said a key feature is the product’s non-custodial design. Binance Wallet does not hold or access user private keys. Instead, it returns unsigned transactions for local signing.
For a limited time, Binance said it is waiving service fees and positive slippage charges. As a result, users will receive all price improvement directly. The company added that the API runs on enterprise-grade infrastructure and comes with 24/7 technical support.
Developers can access the service through Binance’s developer portal. They can use an existing Binance account or a connected wallet.
