FAQ from HashLock OTC

What problem does HashLock OTC solve?

Every existing agent DEX integration has trust assumptions: AMMs have slippage and MEV, RFQ solvers can fail mid-trade. HashLock removes counterparty risk via HTLCs — if either side fails, both sides refund automatically.

How do I get an access token?

Sign in with your Ethereum wallet at https://hashlock.markets/mcp/auth using SIWE. No email or password required. Tokens are valid for 30 days.

What runtimes are required?

For stdio mode, Node.js is required to run the npm command. For remote HTTP mode, any MCP client compatible with HTTP transport (e.g., ChatGPT) can use the provided URL.
