Binance News/Cryptocurrency NewsMaria NikolovaJune 17, 2026Binance Wallet is introducing the Web3 API, a comprehensive suite of API endpoints that enables developers, institutions, and advanced on-chain traders to programmatically access on-chain trading and market data through a single integration. The Web3 API provides secure and scalable access to Binance Wallet capabilities, including real-time market data, swap quotes, and on-chain transaction execution across multiple networks. The Web3 API enables developers and institutions to integrate on-chain trading, market data, and wallet capabilities directly into their applications through a unified set of APIs. Designed for flexibility, security, and scalability, Web3 API simplifies access to on-chain liquidity and execution across multiple networks. Developers can retrieve real-time market data, obtain competitive swap quotes, and facilitate on-chain transactions without managing multiple integrations. By leveraging Binance Wallet’s infrastructure and liquidity aggregation capabilities, Web3 API helps teams build and scale Web3 products more efficiently. Key Features:Market Data API: Access real-time token prices, candlestick (K-line) data, and top gainers/losers across supported chains through a single API. Trading API: Get aggregated swap quotes from multiple vendors, execute token swaps, and broadcast transactions on-chain — with built-in MEV protection. MEV protection mechanisms are incorporated; however, protection cannot be guaranteed in all market conditions. Multi-Chain Support: Build once and access liquidity across multiple EVM chains (e. g. Ethereum, BNB Smart Chain, Plasma, Arbitrum, Polygon, Base, Monad, Optimism, Linea) as well as Solana, with additional chains planned. Competitive Pricing: Quotes are aggregated from leading vendors to find the optimal swap route. Zero Service Fees and No Positive Slippage Charge (for a limited time). All price improvement is returned to the user. Non-Custodial: Binance Wallet never holds or accesses user private keys. The API returns unsigned transactions — users sign locally in their own wallets. Enterprise-Grade Reliability: Backed by Binance Wallet infrastructure with 24/7 technical support. To get started:Visit the developer portal. Login with your Binance account (or connect with your wallet). Bind your phone or email and apply for a Web3 API Key. Follow the [Quickstart Guide] to make your first API call. Explore the full [API Documentation] for all available endpoints.
