1Inch

1inch is a decentralized finance (DeFi) platform best known for its DEX aggregator that sources liquidity from multiple decentralized exchanges to provide users with the best token swap rates. It supports over 13 blockchain networks including Ethereum, Binance Smart Chain, Polygon, Avalanche, and Solana, enabling cross-chain swaps without the need for bridging. The platform uses advanced routing algorithms to split trades across multiple liquidity sources, reducing slippage and fees while optimizing execution efficiency.

Beyond token swaps, 1inch offers a suite of DeFi tools including a secure wallet app for managing assets, a portfolio tracker for analyzing holdings and staking opportunities, and a crypto payment card that integrates with Apple Pay and Google Pay. Its business API suite allows developers and enterprises to integrate 1inch’s liquidity aggregation, token swaps, and RPC node services into their own applications. 1inch also emphasizes security with built-in Maximal Extractable Value (MEV) protection to guard against front-running and sandwich attacks, as well as wallet screening and risk scoring to prevent scams.

What sets 1inch apart is its intent-based swap mechanism, which lets users specify desired trade outcomes and automatically finds the most efficient execution path. Its cross-chain swap capability executes multi-network asset transfers atomically in a single transaction, enhancing user convenience and security. With over $767 billion in swap volume and 26 million wallets connected, 1inch is widely adopted in the DeFi ecosystem. Developers can get started by using the 1inch dApp, wallet, or integrating via the comprehensive Web3 API suite documented on their site.
