What is LucenDEX?

LucenDEX is a neutral, non‑custodial execution layer for XRPL trading. We provide deterministic routing, quoting, and on‑chain settlement so wallets, fintechs, and institutions can access deep XRPL liquidity without building DEX infrastructure themselves.

Non‑Custodial

You hold the keys

All transactions are client‑signed; our backend never sees private keys. Optional relays, zero custody risk.

Deterministic

Cryptographic QuoteHash

blake2b‑256 binds route, price, fees, and TTL; QuoteHash is embedded in the XRPL memo to enforce execution fidelity.

Best Execution

Multi‑route aggregation

Aggregates AMM + orderbook liquidity with path splitting and circuit breakers to avoid anomalies.

How It Works

Deterministic Execution Flow

From quote → hash → sign → settle, with verifiable binding on‑chain.

Client / Wallet LucenDEX Router Quote + Route + Fees → QuoteHash AMMs Orderbooks XRPL Ledger Client signs & submits Memo: • QuoteHash • LastLedgerSequence Use DeliverMin for protection Partner Relay (optional)
  1. Client requests a quote for a pair + amount; router computes optimal path across AMM + orderbooks.
  2. Router returns route, price, fees, TTL, and a cryptographic QuoteHash (blake2b‑256).
  3. Client signs transaction; QuoteHash is embedded in memo. Settlement must match quoted terms.

Who is LucenDEX for?

  • Wallets & frontends embedding XRPL trading.
  • Funds & market makers needing deterministic best‑execution APIs.
  • Token issuers requiring robust liquidity access on XRPL.
  • Custodians & fintechs building compliant, non‑custodial rails.

Security Model

  • mTLS between services; no symmetric key sharing.
  • Ed25519 request signing for partner API endpoints.
  • QuoteHash binding; verifiable memo fields.
  • Circuit breakers & anomaly detection on routes.
