The inclusion of a transaction in a block. A bitcoin or ethereum transaction is considered unconfirmed until it has been included in a block on the blockchain, at which point it has one confirmation. Each additional block is another confirmation.
Here are the number of confirmations that Coinbase requires to consider a transaction final for some of the assets on our platform.
Asset | Number of confirmations |
|---|---|
Bitcoin (BTC) | 2 |
Ethereum (ETH) or other ERC20 assets | 14 |
Ethereum Classic (ETC) | 3,000 |
