LN Markets primary sources — 2026-05-01

Project status in this pass

• No canonical standalone LN Markets whitepaper or litepaper surfaced.
• The clearest current source of truth was the official homepage plus the first-party docs site.
• The docs are largely client-rendered, so several concrete claims were recovered from first-party compiled route bundles referenced by the docs shell.

Primary-source snapshots

1) Official homepage

• URL: https://lnmarkets.com/
• Key excerpts/signals:
  • Says LN Markets is “the ultimate aggregation layer for Bitcoin derivatives.”
  • Says it combines centralized-exchange liquidity with instant settlement and bitcoin-grade security.
  • Emphasizes Lightning deposits, fast position setup, and a personal trading dashboard.
• Why it mattered:
  • The homepage establishes the company’s desired framing: Lightning-native bitcoin derivatives infrastructure rather than just a generic trading venue.

2) Docs shell / metadata

• URLs:
  • https://docs.lnmarkets.com/
  • https://docs.lnmarkets.com/robots.txt
• Key excerpts/signals:
  • The docs metadata says they are the official LN Markets docs for bitcoin derivatives, account operations, and API integration.
  • The docs shell references first-party asset bundles for API, authentication, deposit, withdraw, and futures sections.
• Why it mattered:
  • This shows the docs are real and current even though most content is rendered client-side.

3) REST API route bundle

• URL: https://docs.lnmarkets.com/assets/api-Bpw6N86l.js
• Key excerpts/signals:
  • Says LN Markets offers a REST API for programmatic and trading-bot integration.
  • States the mainnet endpoint is https://api.lnmarkets.com/v3/ and testnet is https://api.testnet4.lnmarkets.com/v3.
  • Documents HMAC-signed private headers: LNM-ACCESS-KEY, LNM-ACCESS-PASSPHRASE, LNM-ACCESS-SIGNATURE, and LNM-ACCESS-TIMESTAMP.
  • Describes a token-bucket rate limiter with 20 tokens/sec and 40-token burst capacity.
  • Lists paginated wallet/account/futures endpoints and notes official TypeScript and Python SDKs.
• Why it mattered:
  • This is the strongest first-party evidence that LN Markets is an API-first trading/control-plane surface rather than only a web UI.

4) WebSocket authentication route bundle

• URL: https://docs.lnmarkets.com/assets/authentication-BRUUGFYF.js
• Key excerpts/signals:
  • Says authentication happens after the WebSocket connection is established.
  • Says WebSocket auth uses the same API keys as REST.
  • Documents signing from timestamp and nonce, replay protection, and rate limits on authenticate attempts.
• Why it mattered:
  • This confirms LN Markets provides a realtime authenticated integration surface, not only request/response REST endpoints.

5) Deposit and withdrawal route bundles

• URLs:
  • https://docs.lnmarkets.com/assets/deposit-BLGOPgfL.js
  • https://docs.lnmarkets.com/assets/withdraw-D_3ZO0HP.js
• Key excerpts/signals:
  • Deposit docs say BTC can be deposited via Lightning, on-chain, or LNURL-pay.
  • Lightning deposits are credited instantly; on-chain deposits credit after 2 confirmations; Lightning minimum is 1,000 sats; LN Markets says it does not charge deposit fees.
  • Withdrawal docs say BTC can be withdrawn via Lightning or on-chain, with Lightning arriving immediately and on-chain withdrawals processed manually.
• Why it mattered:
  • These materials show that Lightning is not a marketing add-on but a first-class operational rail for account funding and withdrawal.

6) Futures route bundle

• URL: https://docs.lnmarkets.com/assets/futures-D1K61vb8.js
• Key excerpts/signals:
  • Says LNM Futures is a perpetual contract whose underlying asset is a weighted basket of BTCUSD perpetual futures from multiple exchanges including Bybit, Binance, OKX, Deribit, and BitMEX.
  • Says basket pricing is used for P&L while execution and liquidation use order-book buckets.
  • Says max leverage is 100x and describes isolated and cross margin, funding fees, and margin-adjustment workflows.
• Why it mattered:
  • This is the clearest first-party explanation of the product design and risk/execution model.

Working conclusion

LN Markets is best cataloged as Lightning-native bitcoin derivatives infrastructure with both user-facing and programmatic trading surfaces. The most important signals in this pass were the explicit REST/WebSocket authentication docs, the Lightning-first deposit/withdraw flows, and the futures design centered on a weighted multi-exchange BTCUSD perpetual basket rather than a single-venue order book.
