Send exactly to:
This asset needs a memo / tag. Send it with or the exchanger cannot credit your deposit.
You receive about at . Exchange reference .
Status: waiting for your deposit
You send from your own wallet straight to the exchanger — nothing to connect, no account, and you stay on this page throughout. Rates are indicative until a swap is opened.
The swap is carried out by an independent exchanger and the deposit address above is theirs. holdium.xyz never holds, receives or controls your funds, has no key to that address, and earns a referral commission. Opening a swap sends your receiving address, IP, browser and timezone to the exchanger for their compliance checks; we store none of it. Check their terms, fees and country restrictions before sending anything.

How well the algorithm picks those decoys determines whether the ring signature actually hides you or leaves a statistical fingerprint th
Your hardware wallet rejected the Monero transaction because the device cannot verify or authorize the cryptographic structure of Monero transactions without specific firmware support, and most hardware wallets do not support Monero at all or require a specialized app.
A view key is a cryptographic tool that allows you to reveal the details of an incoming transaction - such as the amount, sender, and destination - to a third party without granting them any ability to spend those funds. This separates proof of receipt from control of the money.
The short answer is that you cannot send Monero directly to a Zcash shielded address, and any attempt to do so will either fail or result in lost funds. The two cryptocurrencies operate on completely separate blockchains with incompatible privacy mechanisms. This page explains why that is, what actu

You swap from your own wallet. The transaction settles on the chain and you pay its fee.
