Can you cancel or reverse a transaction?

No. Once confirmed, transactions in crypto are permanent. They can't be canceled, altered, or reversed.

No one can cancel or reverse transactions once they have been written to the blockchain (confirmed). This includes Exodus, the sender, the receiver, or any other platforms (custodial or self-custodial) involved.

This is because of the way blockchains work. One of the core principles of blockchain technology is immutability.

What does immutability mean?

When something is immutable, it means that it is permanent and unable to be changed. In blockchains, this is accomplished by cryptography and the hashing process.

Once a transaction is received by the network, it is timestamped and embedded in a block. Blocks are cryptographically secured by a hashing process that links to and incorporates the hash of the previous block. Blocks take place in chronological order, forming a chain - this is why networks in crypto are also known as blockchains.

Once blocks have been hashed, they include metadata from the previous block, and this chronological linking makes the chain unbreakable. A cryptographic hash can't be reverse-engineered.

Transactions are data that are contained in a block. You can't modify or delete data once it has been included in a block because this would break the blockchain. So once a transaction has been included in a block (i.e., confirmed), it cannot be canceled, altered, or reversed.

What are the benefits of immutability?

Some benefits of immutability include:

  • Data integrity: The integrity of the chain can be validated at any time by re-calculating the block hashes
  • Simplified auditing: A complete history, as well as unalterable data, makes auditing easy and efficient
  • Increased efficiency: As well as auditing benefits, provides opportunities in query, analytics, and overall business processes. This includes tracking the provenance of major bugs, auditing specific application data, and backing up and restoring database state changes to retrieve information.
  • Proof of fault: Prevents most disputes related to data provenance and integrity (an unchangeable record of what happened at what time)

What happens if you send crypto to the wrong address?

If you send crypto to the wrong address, it might be lost.

Only the owner of the address would be able to access your funds. Since crypto is anonymous or pseudonymous, there is no way to determine who owns a particular address.

If you have sent crypto to the wrong address, it might be helpful to compare it to the addresses you've sent to in the past to see if you know who the owner is.

If you own the address (can access its private key) or if you can contact the owner, it might be possible to recover your crypto. 

In certain cases, like sending unsupported tokens to your wallet or sending tokens on the wrong network, you can follow a series of steps in order to recover your funds.
