Jumper’s Private Swap Feature. Houdini Integration.
What it does: Jumper has integrated Houdini Swap to offer Private Swaps as a selectable route in its UI, alongside the 33 DEXs and 29 bridges it already aggregates. This lets users move assets across chains and wallets without leaving an observable onchain link between the sending and receiving addresses. Instead of a direct onchain path, Houdini routes each private swap across two off-chain, non-custodial exchange partners and three separate blockchains, then delivers funds from a fresh, single-use wallet. The service is non-custodial and explicitly not a mixer (no pooled funds; sanctions screening and transaction monitoring apply).
How it works
Instead of a direct onchain transaction, each private swap routes through two off-chain, non-custodial exchange partners and three separate blockchains, then delivers funds to the receiving address from a fresh, single-use wallet. The service is non-custodial and explicitly not a mixer: funds are not pooled, and sanctions screening and transaction monitoring apply.
How to use it (per Jumper’s guide):
- Go to jumper.xyz and switch to the Private Swap section.
- Select source chain/asset (e.g., ETH on Ethereum).
- Select destination chain/asset (e.g., USDC on Base).
- Enter amount and review the quote (cost, price impact, fees).
- Enter the receiving wallet address (ideally one with no public link to the sender).
- Sign the transaction.
Why it matters.
Standard cross-chain swaps are traceable by default — matching amounts, timing, bridge records, and EVM address reuse let observers link the two sides in minutes. Jumper notes that swaps over $100k made up 55% of its volume in April (up from 41% in January), so large movers are exactly the users most exposed by transparent rails (MEV, treasury tracking, doxxing).

In fact, I am very impressed with Jumper’s decision to create the possibility of private exchanges between networks. The solution has been in the air for a long time, but Jumper has successfully been able to implement it.
below I will present brief theses of my observations:
Currently live (observed as available):
- Private swaps across 15+ chains, including Ethereum Mainnet, OP Mainnet, BNB Smart Chain, Gnosis, Unichain, Polygon, Fantom, HyperEVM, MegaETH, Base, Plasma Mainnet, Arbitrum One, Avalanche C-Chain, Berachain, and Solana.
- The two-off-chain-partner / three-blockchain routing model with fresh single-use delivery wallets.
- Houdini’s related modes referenced in its blog: No Wallet Connect Swap (receiving address only), Onchain DEX Swap (best-rate routing), and Private Send (private transfers to others).
- Compliance controls: sanctions screening and transaction monitoring; non-custodial, not a mixer.
What is not available yet but upcoming soon:
- Jumper states: “We’ll add more chains in the coming weeks” — so the 15+ chain list is explicitly described as expanding, and additional chains are future functionality, not current.
- Houdini’s blog notes that private routes can take longer than direct onchain routes and that availability depends on the asset pair — a limitation rather than a promised feature, but worth flagging as a constraint on current coverage.
Caveats I’d flag as an observer (not claimed by the sources):
- The sources describe the privacy mechanism at a high level (two exchange partners, three chains, fresh wallets) but do not publish a technical/audit-level specification of the routing or the exact trust assumptions in those off-chain partners — so “no observable connection” should be read as the provider’s claim rather than an independently verified property.
- Privacy depends on user behavior: Houdini explicitly warns that funding a new wallet directly from a linked wallet re-creates the public link, so the feature’s effectiveness is conditional on how the receiving address is used.
That’s all for now, but the list of theses and improvements will only grow over time. In general, it seems that we are on the verge of a new round of development of the crypto market and the Jumper project will play an important role in it.
