+- **Standardized REST API**: Consistent endpoints for interacting with blockchains (Ethereum, Solana) and DEXs (Uniswap, Jupiter, Raydium, Meteora, PancakeSwap, 0x)
 - **Three Trading Types**: Router (DEX aggregators), AMM (V2-style pools), and CLMM (V3-style concentrated liquidity)
 - **Modular Architecture**: Clear separation of concerns with distinct modules for chains, connectors, configuration, and wallet management
 - **TypeScript-based**: Leverages the TypeScript ecosystem and popular libraries like Fastify, Ethers.js, and Solana/web3.js
