Your Crypto Payments
Shouldn't Be Everyone's Business

Public blockchains expose your entire financial life. Every payment, every transaction, forever visible.

Sender & receiver linked

Standard swaps permanently connect your source wallet to your destination on a public ledger anyone can search.

Full history exposed

Anyone with your address can see every token you hold, every trade you've made, and every wallet you've ever interacted with.

Permanent & immutable

Unlike a bank, you can't ask for your records to be hidden. The trail exists forever, with no recourse and no opt-out.

How private swap works

Three steps. Two exchanges. One randomised Layer 1. Zero trace.

step 1

You send token A from any wallet
to Centralised Exchange 1

Enter the amount and destination address. No wallet connection required. Houdini generates a unique, single-use deposit address. Your source wallet is never recorded by any party in the system.

step 2

Exchange 1 swaps your token into a random Layer 1 token and sends it to Exchange 2

A first non-custodial exchange converts your token into a randomly selected, privacy-centric Layer 1 intermediary severing the link to your original asset. The Layer 1 chosen is never disclosed to any observer.

step 3

Exchange 2 delivers token B to recipient

A completely separate, unrelated exchange converts the intermediary asset into your desired token and delivers it. Exchange 2 has no knowledge of Exchange 1, the source wallet, or what was originally sent.

What makes it truly private?

Disappear into the crowd

Even if someone spots your transaction, your destination could be any token on any of 100+ chains. There's no trail to follow. The anonymity comes from the sheer scale of web3 itself. Infinite, and impossible to chase down.

Stay without a trace

Each leg of your transaction simply appears to end. Cleanly, quietly, without a trace. Nobody can connect the dots between where funds came from and where they went.

Your keys, your funds

Houdini never touches your crypto. Every swap flows automatically through non-custodial exchange protocols, start to finish. No pooling, no holding, no counterparty risk. You stay in control the entire time.

Any token. Any chain.

USDC on Ethereum to USDC on Ethereum. Whether you're swapping within the same chain or moving across entirely different networks, every route is available and every route is private.

Battle-tested by skeptics

Houdini has run multiple open trace-a-transaction competitions, putting over $100K in bounties on the line for anyone who could follow the money. Not a single private swap has been successfully traced.

Banking level privacy

A completely separate, unrelated exchange converts the intermediary asset into your desired token and delivers it. Exchange 2 has no knowledge of Exchange 1, the source wallet, or what was originally sent.
