How Much Should You Put Into a Test Swap?

A test swap should be large enough to clear the route’s minimums and fees, but small enough that you could absorb a delay or loss. There is no useful universal dollar amount: the right size depends on the assets, networks and route shown in the swap quote. Check the quote and wallet before sending, since they show the current minimum and expected costs. A small test can confirm that a route works for your setup, but it cannot guarantee a later, larger swap will have the same result.

What should a test swap prove?

A test should check the steps that matter for the larger transfer. Use the same sending and receiving assets, networks, wallet and route you plan to use. Then check that the destination wallet receives the expected asset and that the amount makes sense after fees. The wallet’s transaction record and the destination network’s explorer, a public page showing transaction activity, can help confirm settlement. For the routing and verification steps specific to a thor swap, see the fuller guide. A test with different networks or a different route may not tell you what you need to know.

How do you choose the amount?

Start with the route’s minimum, then account for fees taken from the amount you send. The swap screen may show a minimum output or warn that a small trade will not qualify. Your wallet also shows the network fee needed to submit the transaction; on some networks, this fee is paid in a separate asset. If the test amount barely clears the minimum, fees or price movement may leave too little to complete the swap or judge the result.

• Check the route’s minimum and expected output in the swap quote.
• Check the wallet’s network fee and which asset pays it.
• Choose an amount above those costs that you can afford to have delayed or lost.

That amount may be a few dollars on one route and more on another. Use the amounts shown by the interface when you are ready to send; they can change with network conditions and liquidity, the assets available for trading.

When is a test too small?

A test is too small if the route rejects it, fees take a large share, or the output is too low to verify. In that case, increase the amount only enough to get a usable result. If the minimum or fee makes that amount uncomfortable, pause and reconsider the route rather than sending a token test that cannot answer your question.

Should you test every time?

A test is most useful when you have changed a network, wallet, asset or route, or when the amount is large enough that a mistake would matter. Once the test settles and the destination matches the quote, you have checked those details for that transaction. Check the new quote again before sending more: price, fees and route conditions can change between swaps. The practical rule is simple: test with the smallest amount that still gives a meaningful result, not the smallest amount you can type.
