Change Address

November 21, 2023 - Around 2 mins mins to read

When engaging in cryptocurrency transactions, users may not always have the exact amount to send, similar to traditional fiat money. This can result in sending more funds than what the transaction requires. In such cases, the excess assets are returned to a change wallet and then refunded to the original wallet address.

For instance, if you possess a $50 bill and need to make a purchase worth $40, you will receive $10 as change. The same principle applies to cryptocurrencies. Transactions on the blockchain involve an input and an output. If you buy 1 ETH with fiat currency on an exchange, the input will be the fiat money, and the output will be 1 ETH. However, when sending 1 ETH to a crypto wallet, the process is not as straightforward.

In cryptocurrency transactions, there are situations where the inputs cannot be precisely calculated to match the requested amount. In such cases, the sender’s address sends more funds than what the transaction requires. The difference between the requested amount and the amount stored in the input is referred to as change. This change is temporarily stored in a change address and then refunded back to the sender’s wallet address.

Change addresses play a vital role in the cryptocurrency ecosystem as they enable fair interactions between wallets. Without change addresses, it would not be possible to transfer exact amounts between wallets. Additionally, users are often unaware of the existence of change addresses, as this process is performed by the blockchain itself in the background.

You can view your change address and track the funds that have passed through it. However, no action is required on your part. The blockchain automatically calculates the sender’s input and the necessary output. If the input is insufficient, the transaction will fail. If the input exceeds the requested output, the remaining funds will be sent to a change address and then returned to the sender’s wallet within seconds.

Change addresses are an essential underlying function of all blockchains. Although users may not directly interact with them during transactions, change addresses are frequently utilized. They enable the sending of exact amounts to other wallets and facilitate payments for NFTs, among other use cases.

If you are curious to see your change address, you can easily find it in the transaction details. The change address is visible, even if it was not used in the specific blockchain interaction.
