An on-chain cryptocurrency transaction is completed by transmitting it over a blockchain to process, validate, memorialize, and store it. Not all of these transactions are directly associated with the sender and/or recipient's wallet addresses. On-chain transactions on Coinbase Prime or Exchange include:
Sending cryptocurrency from a Coinbase Vault wallet. This is a publicly available transaction.
Sending cryptocurrency from your Coinbase Prime or Exchange trade balance. These transactions aren't publicly available because they’re bundled and processed together, so they’re not associated with a specific user’s wallet address.
An off-chain cryptocurrency transaction is completed using a system other than a blockchain. For example:
Sending another user your private key to a wallet will transfer custody of the cryptocurrency in the wallet without a blockchain transaction.
Using a third-party guarantor to oversee a transaction and ensure that it’s completed successfully.
