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.
Check the provider's own website for a license number, then verify that number against the official registry of the regulator that issued it. A claim on a website is not proof; the registry is the only part you can trust.
The transaction hash is your receipt, and the block explorer is the ledger. Paste that hash into any explorer for the blockchain you used, and the page will show you the exact addresses that sent and received your funds, plus the amounts and fees.
Check the address the site gives you. If it sends you the same receiving address that other users have seen before, the site is using a shared wallet. If the address is unique to your swap and changes each time, you are getting a dedicated one.
The only reliable way to verify a deposit address is to check it against the address shown inside your account on the exchange itself, after you have logged in securely. No other source - not a previous email, not a saved note, not a chat message - should be trusted as the final
Every cryptocurrency swap works the same way at the mechanical level. You send funds to an address. The exchange detects the deposit. It sends your requested currency to a return address you provided. The entire process is a sequence of transactions on blockchains, and each trans
The swap fails and your funds are either returned to the originating wallet or stuck in limbo, depending on the exchange's policies and the blockchain involved. This happens because a custodial service - an exchange, wallet provider, or trading platform that holds private keys fo

How to convert crypto: on-chain vs off-chain
Off-chain (on an exchange)
Your trade happens inside the exchange's own ledger. Nothing
touches the blockchain until you withdraw.
Cheapest and fastest for common pairs
Needs an account and usually ID verification
The exchange holds the coins until you withdraw them
Best for converting to and from cash
On-chain (a DEX or swap)
You swap from your own wallet. The transaction settles on the
chain and you pay its fee.
No account, no custodian — you keep the keys
You pay network fees, which vary a lot by chain
Small or new tokens often only trade here
Slippage and thin liquidity are real costs on low-volume pairs
Before any on-chain swap: check the token's contract address
against a block explorer, start with a small test amount, and review what you
are approving — an unlimited token approval to an unknown contract is how most
wallet drains actually happen.
