## About

LeoKit is a cross-chain swap and bridge API aggregating 5+ DEX protocols (THORChain, Maya, Chainflip, Near Intents, Relay) across 30+ blockchains with 20,000+ supported tokens. Free to integrate, 0.10% per swap — the lowest fee in the industry.

## Key Features

- **Cross-Chain Swaps**: Swap any token across 30+ blockchains including Bitcoin, Ethereum, Solana, Cosmos, Arbitrum, Avalanche, and more.
- **MCP Server**: AI agents can execute DeFi swaps via the Model Context Protocol (MCP). Compatible with Claude Desktop, Claude Code, Cursor, Windsurf, Cline, and other MCP clients. Install: `npx -y @leodex/leokit-mcp`
- **Non-Custodial**: LeoKit only generates unsigned transactions. Private keys never leave your wallet.
- **Lowest Fees**: 0.10% per swap (10 basis points) — the lowest in the industry. Free to integrate, no credit card required.
- **DEX Aggregation**: 107+ DEXes aggregated for optimal swap routes and best prices.
- **REST API**: Simple GET/POST endpoints. No complex SDKs required.
