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.
An order book shows you the prices at which people are willing to buy or sell right now, while a quoted rate is a single price offered by an intermediary for a swap. The difference arises because an order book represents a market of competing bids and offers, whereas a quoted rat
You move funds to a wallet you control, then use an instant swap service to exchange them for the asset you need. This is the only dependable path when the exchange that holds your money has frozen outgoing transfers.
You swap one asset for another, and the counterparty sends the new asset to a wallet you control. That is the entire mechanism: you never withdraw from the exchange, because the swap happens outside it.
You hold coins on one chain and want them on another. You could sell to a stablecoin on an exchange, transfer to a different exchange, and buy there. Or you could use a swap that sends one asset and delivers another without your funds ever sitting in an exchange wallet. Each path
The spread between the rate you see quoted and the rate you actually receive is the largest hidden cost in any swap. That spread, together with network fees and the slippage that occurs when the exchanger cannot fill your order at the displayed price, can make a swap cost more th
You face limits on swap size, frequency, and asset availability when you swap without an account. Providers enforce these limits through automated rate adjustments, minimum and maximum thresholds, and occasional manual review.

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.
