Hashlock Markets

hashlock-tech/hashlock-mcp

Connects Claude and other MCP clients to Hashlock Markets for atomic cross-chain OTC settlement on Ethereum, Sui, and Bitcoin mainnet via HTLCs. Six tools: create and respond to sealed-bid RFQs, fund HTLCs, claim with preimage, refund expired locks, and query settlement status. No bridges or custodians. Supports remote streamable-http (no local install) or stdio via npx. Requires a 7-day SIWE bearer token from their login page. Built for AI agents that need to execute trustless cross-chain swaps without wrapped tokens or third-party escrow.
