What is Hashlock Markets?

Hashlock Markets is a universal asset exchange protocol built by Hashlock-Tech. Counterparties submit private sealed bids for each swap intent — no one sees competing bids — so trades settle at the best price without front-running, MEV extraction, or slippage. It supports cryptocurrencies, tokenized real-world assets (RWA), and stablecoins across Ethereum, Bitcoin, and SUI, with atomic settlement via Hash Time-Locked Contracts (HTLCs).

Is Hashlock Markets the same as the cryptographic "hashlock" used in HTLCs?

No. The cryptographic "hashlock" is a primitive used inside Hash Time-Locked Contracts. Hashlock Markets (hashlock.markets, built by Hashlock-Tech) is a complete trading platform and protocol. The name references the cryptographic heritage, but the product is an exchange — not a primitive. Think "Java the language" versus "java the beverage".

What assets can I trade on Hashlock Markets?

Any supported asset on any supported chain: major cryptocurrencies (ETH, BTC, SUI), ERC-20 tokens, stablecoins (USDC, USDT, DAI), and tokenized real-world assets including bonds, real estate, and commodities. Cross-chain pairs are supported natively.

How does sealed-bid swap execution work?

When you create a swap intent, verified counterparties submit private bids that neither you nor other bidders can see. The protocol selects the winning bid based on price and counterparty reliability. Because bids are sealed, there is no front-running, no MEV sandwiching, and zero slippage — the agreed price is the final settlement price.

Which blockchains does Hashlock Markets support?

Ethereum mainnet, Bitcoin (via HTLC), and SUI are live today. Cross-chain swaps settle atomically through time-locked contracts on each chain, so either both legs complete or neither does.

How do AI agents integrate with Hashlock Markets?

Three first-class integration paths: (1) an MCP server (hashlock-mcp-server on npm) compatible with Claude, Cursor, Windsurf, and any MCP client; (2) a Vercel AI SDK toolkit (hashlock-ai-sdk on npm) for TypeScript agents; and (3) a LangChain integration (langchain-hashlock on PyPI) for Python agents. Agents can create, validate, and commit swap intents autonomously.

Is Hashlock Markets custodial?

No. Settlement is non-custodial via HTLC atomic swaps — funds move directly between counterparties wallets on-chain. Hashlock-Tech never holds user assets.

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.

GraphQL performance pass and full SUI integration

A major round-trip reduction on the frontend and end-to-end SUI support, plus a handful of chat and socket reliability fixes.

HTTP GraphQL operation batching: per-page request count dropped from roughly 30 to 2–3
Full SUI chain integration: provider, explorer, schema, and wallet options
WebSocket browser traffic routed through nginx instead of direct container ports (fixes staging TLS path)
Chat call silent-fail fix, dealing-code format fix, and pageSize ceiling enforcement
Duplicate (dashboard)/page.tsx removed so pnpm build no longer conflicts with app/page.tsx

Ethereum mainnet deployment

Production HTLC contracts are live on Ethereum mainnet. Both the base HTLC and ERC20Fee wrapper are deployed, verified on Etherscan, and enforcing the configured protocol fee.

HTLC core contract deployed to Ethereum mainnet with fee enforcement
ERC20Fee wrapper deployed and verified on Etherscan
Default contract addresses updated across chain-watcher and web runtime config

Cross-asset ERC20/BTC settlement

First end-to-end cross-chain atomic settlement between an ERC20 token on Ethereum and native BTC on Bitcoin. The HTLC preimage now auto-claims on the counterparty leg with no manual entry.

Cross-asset ERC20/BTC settlement shipped; multi-chain token registry added
Auto-send BTC via browser wallet extensions (Xverse, Leather)
Auto-calculate BTC satoshi amount from trade data; auto-fill BTC pubkeys from user_wallets
ERC20Fee MIN_AMOUNT lowered to accommodate 6-decimal tokens (USDT, USDC)
Preimage stored in DB so auto-claim no longer requires a human to paste the secret
ERC20 gas estimation + allowance verification hardened before the settlement transaction is sent

Chat-centric trading UI polish

A focused week on the chat-centric terminal: bilateral call signaling, blind-auction identity masking, and a set of RFQ socket reliability fixes that made the auction flow instant.

Bilateral call:ended signaling — both counterparties transition to read-only on END CHAT
Instant auction close on trade confirm via an rfq:closed socket event
Blind Auction: comprehensive counterparty identity masking with creature pseudonyms
Auto-purge non-trade conversations on END CHAT so the sidebar stays clean
Glassmorphic amber-tinted toasts with backdrop blur; HUD header restyled to Bloomberg amber
Selective-service deploy script (deploy-staging.sh) that eliminates the gateway race on rebuilds

Blind auction and trade cycle popup

Blind-auction RFQs landed as a first-class toggle, and the trade cycle popup moved to the bottom tray so the full RFQ-to-settlement lifecycle is visible in one view.

Blind Auction — isBlind toggle on RFQ with counterparty identity masking
Trade cycle popup from bottom tray; completed trades filter through to the blotter
Sepolia, Bitcoin Signet, and Sui Testnet added as selectable wallet chains
RFQ watch defaults to ON for users without a saved preference
Dealing-code copy works on plain HTTP via a clipboard-API fallback
Market-price gate: RFQs without a live price are blocked; Binance REST fallback when WS drops
