FAQ
Frequently asked questions
Is Hashlock Markets custodial?
No. Settlement is non-custodial via HTLC atomic swaps — funds move directly between counterparties' wallets on-chain. Hashlock Corp never holds user assets.
Which blockchains does Hashlock Markets support?
Ethereum and Sui mainnets are live today. Bitcoin uses native P2WSH HTLC scripts — there is no smart contract to deploy, so the protocol is mainnet-capable from day one; signet has been used for end-to-end validation, and the first BTC mainnet settlement is gated on counterparty match plus operational sign-off rather than on additional development. Cross-chain swaps settle atomically through time-locked contracts/scripts on each chain, so either both legs complete or neither does. Base, Arbitrum, Solana, BNB Chain, and TON are on the active expansion roadmap.
How do AI agents integrate with Hashlock Markets?
Two first-class integration paths: (1) an MCP server (@hashlock-tech/mcp on npm) compatible with Claude, Cursor, Windsurf, and any MCP client — use either remote streamable-http at https://hashlock.markets/mcp or local stdio via npx; (2) a Vercel AI SDK toolkit (hashlock-ai-sdk on npm) for TypeScript agents. Agents can create, validate, and commit swap intents autonomously.
How are counterparties on Hashlock Markets verified?
Institutional counterparties complete KYC and institutional verification before joining the network. Trade history and reputation are tracked per verified entity, and sealed bids are only accepted from verified parties.
