Houdini Swap's private swaps unlink your sending and receiving addresses by routing the trade through two off-chain exchange partners. Chainflip is not part of that private route. It is one of Houdini's standard on-chain routes for native swaps. Houdini crossed US$3 billion in cumulative swap volume as of September 22, 2026. According to SOL Strategies, Houdini's owner, private swaps made up 74% of its August 2026 volume. You can also swap native BTC to ETH directly on Chainflip.
What is Houdini Swap?
Houdini Swap is a crypto swap aggregator that compares routes across exchanges and DEXs. The company says it requires no account, KYC or personal data, and claims support for 3,000+ tokens across 30+ blockchains (Houdini company description and NoKYCScore, November 2026).
Company-reported figures from SOL Strategies put monthly volume at about US$65M in June, US$66M in July and US$74M in August 2026 (Nasdaq).
How does a Houdini private swap work?
A Houdini private swap breaks the on-chain link between your sending and receiving addresses by splitting the trade across two separate exchanges. Houdini's Private Swap documentation (current docs, November 2026) says the transaction routes through two exchange partners and uses a temporary Layer 1 token as an intermediary. Houdini's product page describes each route as crossing two off-chain exchange partners and three blockchains.
Because the swap needs two cross-chain executions, Houdini says it can take 5 to 50 minutes. Houdini does not name Chainflip as part of this private route. The privacy comes from the off-chain exchange hops, not from any on-chain protocol.
Where does Chainflip fit into Houdini Swap?
Chainflip is one of Houdini's on-chain swap routes, used for standard native asset swaps rather than private swaps. Houdini integrated Chainflip as one of its first launch partners in early 2024, using the Chainflip SDK to improve pricing and routing for native Bitcoin swaps (Chainflip blog).
Houdini's release notes (current as of November 2026) add two practical details. You can fund on-chain swaps on the Chainflip and Near Intents routes by sending to a deposit address with no wallet connection. Completed Chainflip orders also show the payout transaction hash.
When Houdini picks the Chainflip route, the swap settles natively on each chain. Validators secure the funds under a decentralized custody model, with no centralized custodian. You can trace the deposit and payout on Chainflip Scan. Anyone can verify the route, which also means it offers no privacy.
How do you make a private swap on Houdini Swap?
You make a private swap entirely inside Houdini's own interface, and Chainflip has no role in this flow. The steps:
Open Houdini Swap and choose the asset you're sending, the asset you want to receive, and the amount.
Select the private swap type. Standard routes, including Chainflip, settle on-chain and don't unlink your addresses.
Enter your receiving address. A fresh address with no history tied to your sending wallet gives the private route more to work with.
Send funds to the deposit address Houdini shows you. Check every character first, since fake swap sites and address poisoning target exactly this step.
Wait for both legs to complete. Houdini's 5 to 50 minute estimate applies, so a slow arrival is normal.
Your own habits also affect privacy. Sending an unusual exact amount and receiving nearly the same value soon after can still hint at a connection. Avoid receiving into addresses already linked to your identity.
How much does a Houdini Swap cost compared with a direct Chainflip swap?
Houdini says it adds no fee on top of its exchange partners' fees and searches many routes for the lowest-cost path (Houdini Swap ETH page, November 2026). Private swaps cost more, though: review site NoKYCScore estimates they run roughly twice a standard swap because they use two legs. That's the reviewer's characterisation, not an official Houdini figure.
Direct Chainflip swaps follow a published fee schedule in the Chainflip docs (page indexed September 2026):
Fee | Direct Chainflip swap |
|---|---|
Network fee (buy/burn) | 0.10%, or 0.01% for internal stablecoin swaps, with a $0.5 minimum |
Boost fee (optional) | 0.05% to 0.3% |
Deposit and destination gas | Varies by chain |
Refund fee | $0.5 minimum |
Fees are only part of the cost, since price impact and spread matter too. Our guide to benchmarking what a cross-chain swap really costs shows how to compare quotes fairly.
Should you use Houdini Swap or Chainflip directly?
Use Houdini's private swap when unlinking your addresses matters more than speed and cost, and use Chainflip directly when you want transparent native settlement.
When Houdini's private route makes sense
You want sender and receiver addresses unlinked on-chain.
You can wait up to 50 minutes and accept roughly double the fees.
You accept partner risk. NoKYCScore rates Houdini a KYC level 3 aggregator and flags ID risk, because swaps pass through partner exchanges.
When a direct Chainflip swap makes sense
You want to buy native BTC or sell ETH for native BTC without wrapped tokens or a centralized exchange in the path.
You want a verifiable on-chain record of every step.
You prefer a published fee schedule over a partner's spread.
Chainflip processed $727M in swap volume in October 2026, up 17% from $622M in October 2025, and $10.42B all-time (Chainflip Scan). For more options, see our comparison of five ways to exchange crypto to crypto without a CEX.
Private or native settlement?
Houdini Swap's private route gets its privacy from two off-chain exchange hops, not from Chainflip. Chainflip powers a different part of Houdini: on-chain native swaps you can fund from a deposit address without connecting a wallet.
If privacy is your goal, use Houdini's private swap and keep good address hygiene. If you want native settlement with transparent fees, start a swap on Chainflip and track it on Chainflip Scan.
