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. venko.tech 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.

A wallet watch-only import is a way to add a public address or extended public key (xpub) to your portfolio tracker without giving that tracker access to your private keys or spending authority. You use it when you need visibility into balances and transactions but want to keep the wallet itself off
Importing a MetaMask transaction history without gaps requires combining the wallet's native CSV export with an Etherscan API pull or a third-party aggregator, because MetaMask's own export omits certain transaction types and older records.
Your exchange dashboard shows one number, but your portfolio tracker shows another. This is almost always because the two systems are using different data - different subsets of transactions, different timing, or different valuation methods. The tracker includes transactions the exchange never recor
A hard fork splits your holdings into two separate assets, and your tracking software needs a manual intervention to keep records honest. The core task is to ensure your pre-fork cost basis carries over to the original chain, while the new chain's tokens get a cost basis of zero (in most jurisdictio

Your trade happens inside the exchange's own ledger. Nothing touches the blockchain until you withdraw.
You swap from your own wallet. The transaction settles on the chain and you pay its fee.
