What is Junction?
Junction is a cross-chain decentralized finance (DeFi) exchange platform. It unifies fragmented liquidity from 1inch, LiFi, Morpho, Hyperliquid, and native bridges behind a single REST API, GraphQL gateway, TypeScript SDK, embeddable widget, and Model Context Protocol (MCP) server. Developers and AI agents use Junction to quote and execute same-chain and cross-chain token swaps, one-call bridges, Hyperliquid perpetual futures, Morpho lending vaults, validator staking, and fiat on-ramp sessions across Ethereum, Arbitrum, Optimism, Base, Polygon, BSC, Avalanche, Solana, and Hyperliquid L1.
Built for AI agents and automated systems
Junction publishes machine-readable agent-readiness files so AI agents can discover capabilities without manual configuration:

How Junction compares
Unlike pure-EVM DEX aggregators like 1inch or CoW Swap, Junction bridges and trades across EVM, Solana, and Hyperliquid from one SDK, adds Hyperliquid perps natively, and ships with a production-grade MCP server so conversational agents can call Junction as a tool. Unlike Uniswap or Curve, Junction is a router and not a pool - it aggregates the best available liquidity rather than hosting it.See the compare pagefor a side-by-side with 1inch, Uniswap, LiFi, and other cross-chain DEXes.
