Swapping assets across chains without wrapping tokens

You want to move an asset from one blockchain to another. The usual solution is a bridge: you deposit tokens into a smart contract on chain A, and a corresponding representation of those tokens is minted on chain B. That representation is a derivative, not your original asset. If the bridge is exploited, that derivative becomes worthless.

The exchanger on this page does something different. It never holds your funds. It does not mint wrapped tokens. It moves your actual asset from one chain to another by swapping it on the destination chain after receiving it on the source chain. There is no intermediate token, no centralised account, no custody of your coins at any point.

How do non-custodial swap services move assets between blockchains. The exchanger runs software that monitors a deposit address on chain A. When your transaction reaches the required number of confirmations, the exchanger simultaneously generates a withdrawal transaction on chain B using its own liquidity. It then transfers the private key or signs the transaction so that you can claim the funds. The exchanger never holds both legs of the trade at the same time; it commits to the pay-out before it can retrieve the deposit. This is the fundamental guarantee that makes a cross-chain swap non-custodial.

What is a cross-chain swap and how does it settle without a bridge. A cross-chain swap is a coordinated exchange of assets on two different blockchains that settles atomically or near-atomically. Without a bridge, settlement relies on cryptographic hash locks. You send your coins to a hashed time-locked contract on chain A. The exchanger reveals the preimage to claim those coins, and that same preimage is used on chain B to let you claim the swapped coins. If the swap fails, both sides refund after a timeout. The exchanger cannot run away with your deposit because it never gets the preimage until it pays you on chain B.

What is the difference between a bridge and an exchanger for moving crypto across chains. A bridge locks your tokens and issues a synthetic version on another chain. That synthetic token carries the bridge's counterparty risk. An exchanger, by contrast, completes two separate swaps: it receives your asset on chain A and pays you a different asset on chain B. No synthetic token is created. The risk is limited to the few seconds during which the exchanger has committed to pay but has not yet claimed its deposit. Most exchangers close this gap with atomic swap protocols.

How do you swap ETH to SOL in one step without using a centralised exchange. You do not need to sign up for anything or deposit funds into a web wallet. You send ETH to the address the exchanger gives you. The exchanger checks for confirmations on Ethereum. Once enough blocks have passed, the exchanger sends SOL to the Solana address you provided. The entire interaction is one outgoing transaction from your wallet and one incoming transaction to your wallet. No account, no KYC, no withdrawal limits.

How long does each blockchain take to confirm a cross-chain swap. Confirmation times depend on the source chain's block time and finality. Ethereum typically requires 12 to 30 block confirmations before the exchanger considers the deposit safe, which takes roughly 3 to 8 minutes. Solana confirms in under a second, but the exchanger may wait a few seconds to avoid reorganisations. Bitcoin takes about 30 minutes for six confirmations. The total time from deposit to receiving funds is the source chain's confirmation window plus a small processing delay on the exchanger's side. The destination chain's transaction is usually broadcast within a minute of that confirmation.

What happens if you send the right coin on the wrong network during a swap. This is the most common irreversible mistake. If you send USDC on Ethereum when the swap expects USDC on Polygon, your transaction arrives on Ethereum and the exchanger is not watching that address on Polygon. The exchanger will not have the private key to the destination address on the chain you used. Your coins are not lost in the sense that the chain holds them, but the exchanger cannot retrieve them and will not refund them. Always verify that the network dropdown or indicator on the form matches the chain you are sending from.

Why does the same token have a different contract address on each chain. A token is a smart contract; each blockchain has its own contract registry. USDC is a smart contract on Ethereum at one address, on Polygon at another, on Solana at a third. These are independent deployments controlled by different entities or governed by different DAOs. The exchanger identifies the token by its contract address on each chain, not by its ticker symbol. Swapping based on ticker alone is a common source of errors.

Why do some swaps ask for a memo or destination tag. Memos are used on blockchains like Stellar, Ripple, or Cosmos IBC transfers where one address can hold multiple user balances. Without the memo, the exchanger cannot know which user the incoming deposit belongs to. If you omit the memo, the exchanger sees the funds arrive but cannot link them to your swap. The swap will time out, and you will need to contact support with proof of the transaction. The funds are not lost, but recovery requires manual intervention and can take days.

What can go wrong. You can send too little, so the swap fails and you get a refund minus network fees. You can send to a smart contract address that the exchanger cannot control, locking the funds permanently. You can use a token with a transfer fee that reduces the amount below the minimum, causing a refund minus the fee. None of these are the exchanger's fault, but the exchanger is the party you will ask for help.

What cannot be undone. If you send the correct token on the correct chain to the correct address but the exchanger's automated system fails to process the swap, the transaction is already on the blockchain. The exchanger may refund after a timeout, but the network fee you paid is gone. If you send to a wrong address, that transaction is final. No one can reverse it.

The form below lets you select source and destination chains, tokens, and addresses. The exchanger will show the expected rate, the estimated time, and the exact deposit address. Send exactly the amount shown to that address. Check the chain, the contract address, and the memo if one is required. Then wait. The funds will arrive on the destination chain.
