Risk disclosure
Everything on this page is a way somebody has actually lost money in a self-custody swap. It is worth five minutes before your first one.
Transactions cannot be undone
A blockchain transfer, once broadcast, is permanent. There is no chargeback, no dispute process, and no authority that can reverse it. This single fact underlies every other risk on this page.
Sending on the wrong network
The same ticker exists on many chains. USDT alone runs on Ethereum, Tron, BNB Chain, Solana, Polygon and a dozen others, and those tokens are not interchangeable. A deposit address generated for one chain usually cannot receive funds from another, and coins sent that way are typically gone.
This is the most common way people lose money in swaps, which is why the picker asks you to choose the coin and the network as two separate decisions, and shows the name your wallet is likely to use — ERC20, TRC20, BEP20 — alongside the technical one.
Missing memos and tags
Some coins, XRP and TON among them, route deposits using a second field called a memo or destination tag. A deposit that arrives without it cannot be matched to your order automatically. Recovery is sometimes possible through the provider's support, but it is slow and not guaranteed.
Price movement while you wait
On a floating rate, the final amount is calculated when your deposit confirms — not when you saw the quote. In a fast-moving market the difference can be significant, in either direction.
A fixed rate protects you from this for a short window, at a slightly wider spread. If your deposit arrives after that window closes, the order may be re-priced or refunded.
Amounts below the minimum
Every pair has a floor, set by what it costs to move the coin on-chain. A deposit below it cannot be processed economically and may be lost or returned minus fees. The widget shows the minimum for your exact pair before you commit — check it, particularly on chains with high fees.
Delays and stuck orders
Most swaps settle in five to thirty minutes. Network congestion, low fees on your outgoing transaction, or a liquidity issue at the provider can extend that considerably. An order stuck in confirming is usually waiting on the blockchain, which no exchange controls.
Keep your swap ID. Without it, an order cannot be looked up — a wallet address alone is not enough.
Compliance holds
Liquidity providers run automated anti-money-laundering checks on incoming funds. If the coins you send have on-chain history their systems flag — a sanctioned entity, a known mixer, a hacked exchange somewhere in the trail — the swap can be paused pending identity verification, refunded, or in rare cases frozen.
This can happen even when you personally did nothing wrong, because the history attaches to the coins rather than to you. These decisions belong to the provider; Vareno cannot override them.
Legal status where you are
Cryptocurrency services are restricted or prohibited in some jurisdictions, and sanctions regimes apply regardless of where a website is hosted. Establishing that your use of this service is lawful where you live is your responsibility, not ours.
Reducing your exposure
- Send a small test amount first, and only scale up once you have seen one complete
- Paste addresses rather than typing them, then check the first and last characters
- Confirm the network on both sides matches what your wallets expect
- Prefer a fixed rate on volatile days or when you owe an exact amount
- Save the swap ID somewhere before you send anything
- Do not send funds you cannot afford to lose
