How to refund a Transaction?

Note: Moonriver (MOVR) on Kusama is a companion network to Moonbeam and provides a permanently incentivized canary network. New code ships to Moonriver first, where it can be tested and verified under real economic conditions. Once proven, the same code ships to Moonbeam on Polkadot.

Polygon PoS ( is an EVM-compatible environment optimized for high throughput and low transaction fees while Polygon zkEVM ( is an EVM-equivalent ZK rollup designed for security.

Some of the most common cases where a refund request is usually submitted are:

  • Sent ETH/tokens to the wrong address
  • Sent the wrong amount of ETH/tokens
  • The transaction took too long
  • The transaction is dropped by the network

Due to the irreversible nature of digital currency protocols, successful transactions cannot be cancelled and are irreversible. As such, when cases such as the above happen, you are most likely to never be able to recover the lost fund.

The only person able to issue a refund is the person holding the coins – the owner of the address. If you do not know the owner of the address, there is no other way to retrieve the funds.

There is also no guarantee that anyone has the private key to a certain address, especially if the address has no outgoing transactions. Therefore, it is essential to exercise caution whenever you are sending funds. Always double-check that the address you are sending to matches the address of the recipient exactly. It is best practice to double-check the address before confirm or executing the transaction.

Funds sent wrongly to exchanges may be recovered at the exchange’s discretion. Exchanges may be able to help you if you open a support ticket and give them the details they need, i.e., the address you meant to send to, and the transaction hash that went to the wrong address.
