# Private Swap

> Privacy-first, non-custodial cross-chain swaps designed to eliminate on-chain traceability.

## **What is a Private Swap?**

Private Swaps are Houdini’s flagship routing option, engineered for users who require the highest level of transactional privacy. A Private Swap breaks this link by routing the transaction through two separate non-custodial exchanges and utilizing a temporary Layer 1 token as an intermediary.

Over **\$1.5 billion** in private swap volume has been processed to date, making it one of the most-used compliant privacy tools in crypto.

  **Key Characteristics**

  * **Maximum Privacy:** The sender and receiver addresses are not linked on-chain, making Private Swaps the ideal choice for privacy in crypto.
  * **Non-Custodial:** Houdini never takes possession of your funds; the process is entirely automated via exchange protocols.
  * Same-Chain: Send/receive the same token on the same chain (e.g. USDC-ETH to USDC-ETH)
  * **Cross-Chain:** Any token, any chain to any token, any chain (e.g. USDT-TRC20 to BTC)
  * **Battle Tested:** Over \$1.5 billion in Private Swap volume since inception.

## **How it Works**

A Private Swap routes each transaction through two unrelated intermediaries:

1. **Leg 1 (Source Chain):** You send **Token A** from your source wallet. This is routed to a non-custodial exchange and swapped into a temporary, privacy-centric Layer 1 intermediary token.
2. **The Intermediary Step:** This temporary asset acts as a "buffer," effectively breaking the trail of the original transaction.
3. **Leg 2 (Destination Chain):** The intermediary asset is routed to a second non-custodial exchange, swapped into your desired **Token B**, and delivered to the recipient wallet.

By the time the funds reach the destination, the on-chain "paper trail" connecting the original sender to the final receiver is completely severed.

## **What Makes it Private?**

Houdini Swap is the undisputed leader in transactional privacy. There is a reason why over \$1.5 billion has processed through its platform.

* **No Direct Link:** The sender and receiver never appear in the same transaction nor transaction trail.
* **No Transaction Markers:** There are no deterministic data markers that show this is a "Houdini Swap" transaction. Each Leg of the transaction is unique and *appears* to end, so it's impossible for observers to prove that Leg 1 and Leg 2 are part of the same swap. To an outside observer, each leg looks like a standard, unrelated transaction.
* **Infinite Anonymity Set:** Even if an observer determined it was a Houdini Swap transaction, Leg 2 could be on any chain, denominated in any token. The Anonymity set is bootstrapped by the entirety of web3 (i.e. infinite) since Houdini Swap covers 100+ chains and thousands of tokens.
* **Battle Tested:** Houdini Swap has initiated multiple "Trace a Transaction" competitions for bounties over \$100,000. No transaction has been traced by the public.

    * **Business Operations:** Organizations using crypto for payroll, treasury management, or sensitive vendor payments.
    * **Influential Traders:** Whales or public figures who want to move funds without signaling their intent to the broader market.
    * **Privacy-Conscious Users:** Anyone who values their security and is looking to move funds without exposing their wallet balance or history.

  <Card icon="circle-xmark" title="Not Recommended For:">
    * **Micro-Transactions:** Small, everyday swaps where the cost and time of privacy routing may outweigh the benefits.
    * **Time-Sensitive Trades:** Arbitrage or "degen" plays where execution speed is more important than privacy. Private Swaps require multiple liquidity checks and two separate cross-chain executions; timing can range from 5-50 minutes.
