Hide Trail
This feature is powered by Houdini Swap, a swap aggregator with a unique private mode that routes funds through two exchanges to remove the link between your existing address and the newly funded one.
The full flow typically takes between 5 and 30 minutes and partner exchanges use live AML monitoring to ensure compliance.

Combined with Fluidkey’s stealth addresses you get the best of both worlds: your funds are both untraceable and unlinkable onchain.

The integration is available for incoming transfers with a value of $60 to $100,000 across the chains and tokens listed below.
| Chain | Available tokens |
|---|---|
| Ethereum | USDC, DAI, USDT, WETH, EURC, wstETH |
| Polygon | USDC, DAI, USDT, wstETH |
| Arbitrum | USDC, DAI, USDT, wstETH |
| Optimism | USDC, USDT, wstETH |
| Base | USDC |
To get started, simply tap the activity details of an incoming transfer and press the Hide Trail button.
