What Happens After You Send a Cross-Chain Swap?

After you send a cross-chain swap, the source blockchain must confirm your deposit before the swap service can exchange it and send the result on the destination chain. That means the transfer has several steps, and seeing the first transaction confirmed does not mean the funds have arrived.

For example, in a THORChain swap, network nodes watch for deposits, then the protocol carries out the requested swap and arranges an outgoing transaction. The thor swap guide covers that design in more detail. Other services may use different protocols or routes, so the exact steps and status labels vary.

What happens after the deposit is confirmed?

The swap service checks that the deposit arrived with the details needed to process it, such as the intended asset and destination. It then performs the exchange. In some systems, the route between two assets passes through a third asset or pool; this is part of the protocol’s plumbing, not another action for you to take.

The amount received can differ from the estimate shown before you sent the funds. A pool swap changes the balance of the pool, which affects the price; this effect is called price impact. The service may also deduct network costs and a swap fee. A minimum-output setting tells the service the least you will accept. If the swap cannot meet that limit, the protocol may stop or refund the trade, depending on its rules.

Why can the destination transfer take longer?

The source and destination are separate blockchains. Each has its own block times, congestion and confirmation rules. After the swap, the service still needs to create and broadcast a transaction on the destination chain. That transaction may wait for network capacity, even when the source deposit is already confirmed.

Some protocols split a large swap into smaller parts over time. This can reduce price impact, but it can also mean the exchange takes longer. A single quick swap may finish sooner, while a split swap gives the pool more time to adjust between parts. The app’s estimate should reflect its chosen route and settings, though it cannot guarantee how busy either network will be.

What should you check if the swap is still pending?

Use the transaction hash—the public ID for a blockchain transaction—to check the deposit on its source-chain explorer. Then check the swap service’s status and, once available, the outgoing transaction on the destination chain. A pending label can refer to any stage, so look for which transaction has confirmed.

• Confirm the destination address and selected network are the ones you intended.
• Compare the amount received with the quoted minimum, allowing for the fees shown by the service.
• If the service reports a refund or failure, check which wallet and chain it says will receive the funds.

The practical rule is to track both sides of the swap. A confirmed deposit proves the funds left your wallet; only a confirmed destination transaction shows that the swap has completed.
