Changes to Coinbase Pro withdrawal fees
To ensure a smooth and secure experience for our customers and reasonable transaction processing times, Coinbase Pro will begin implementing crypto withdrawal fees starting today based on our estimate of the network transaction fee. This network fee will always be fully disclosed to you at the time of your withdrawal on pro.coinbase.com or within the Coinbase Pro mobile app.
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.
