How does a cross-chain swap work? — 4 steps

From opening the page to receiving your assets usually takes 1-10 minutes. No sign-up, no wallet connection, no KYC at any point.

  1. 1
    Pick assets and amount

    Choose the source and destination chains and tokens, then enter an amount. The system returns a live quote.

    All-in fixed quote: the quoted number is the final amount you receive
  2. 2
    Enter the receiving address

    Enter the wallet address where you want to receive the asset. We validate the format, but never look it up on-chain or collect PII.

    No on-chain lookups, privacy preserved
  3. 3
    Send to a one-time deposit address

    Send from your own wallet to the deposit address we generate. No wallet connection, no approvals, no signatures.

    No approvals, no connection, zero exposure surface
  4. 4
    Wait for delivery

    The routing network performs the cross-chain swap automatically and sends the asset to your receiving address. Usually 1-10 minutes, with no fees beyond the quote.

Cross-chain swap fees

One all-in fixed quote at the best available rate — destination-chain gas, bridge gas, and spread are all included. Not a cent is deducted beyond the quote.

Example: you swap 100 USDC and UpSwap shows "You receive 99.x USDC" — then it is exactly 99.x USDC, down to the last digit (the number shown is the final amount that arrives).

How does a cross-chain swap keep your funds safe?

There is no fund-holding attack surface — UpSwap's code path never handles your assets at all.

No custody

UpSwap never touches your assets at any point. Even if our servers were fully compromised, an attacker could not reach a single user fund — the code path simply never handles assets.

No approvals

You never connect a wallet, approve a contract, or sign anything. One single send, the order completes, and no ongoing exposure surface remains.

Refund on failure

If routing fails unexpectedly, the system issues an automatic refund to the source address. Failed orders incur no service fee — only the physical gas of the on-chain refund transfer is deducted.

Cross-chain swap FAQ

How do I make a cross-chain swap?

It takes 4 steps: ① choose the coins and amount → ② enter your receiving address → ③ send your tokens to the designated address → ④ wait for them to arrive. No sign-up needed, and the whole process is on-chain and non-custodial.

Which chains do you support?

14+ chains: Ethereum, Solana, BNB, Base, Arbitrum, Optimism, Polygon, Bitcoin, Tron, NEAR, Avalanche, and other major blockchains.

How do I know I'm getting the best rate?

For every swap, we compare live quotes across multiple cross-chain routes and automatically pick the one that pays you the most. The quote already includes all fees — no hidden costs. It refreshes automatically before it expires, so what you see is what you get.

Is my money safe? What happens if something goes wrong?

We are a fully on-chain, non-custodial platform — we never touch or hold your funds at any point. Swaps are executed by the underlying on-chain contracts, which have gone through multiple rounds of independent security audits with no record of fund loss to date. If a route fails unexpectedly, the system issues an automatic refund to the source address of your deposit.

Do I need to sign up or complete KYC?

No. We collect no personal information — no email, phone number, or identity verification. Just open and use. Your order history is saved only locally in your browser; we store no user data, and you stay fully anonymous on-chain.

Do I need to connect a wallet or sign any approvals?

No. There is no wallet connection at any point, and no token approval transactions are required. After you place an order, you get a one-time deposit address and send the funds yourself from any wallet or exchange. Since there are no approvals at all, the common risk of funds being drained through phishing via unlimited approvals simply does not exist.

How long does a swap take?

Usually 1-10 minutes, depending on block confirmation speed on the source chain. Solana / Tron are typically the fastest; Bitcoin needs 1-3 confirmations.
