To ensure that transactions are processed on cryptocurrency networks, outgoing transactions to external cryptocurrency addresses typically incur a "mining" or "network" fee. This fee is paid to cryptocurrency miners, which are the systems that process the transactions and secure the respective network. Historically, Coinbase Pro has absorbed these fees on behalf of our customers. However, as crypto has begun to gain broader adoption in applications like DeFi, payments and other projects, networks have gotten busier which leads to longer wait times and higher fees as users compete to get their transactions confirmed faster.
To ensure a smooth experience for our customers and reasonable transaction processing times, Coinbase Pro will charge a fee based on our estimate of the network transaction fees that we anticipate paying for each transaction. In certain circumstances, the fee that Coinbase Pro pays may differ from that estimate. All fees we charge will be disclosed at the time of your transaction.
