Binance 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.
