USDC withdrawals are FREE across all supported networks. Coinbase will cover network fees on behalf of our customers.
What are Network Fees?
Also known as a miner's fee, a Network fee is an amount of a blockchains native cryptocurrency that a sender pays to miners in order to incentivize them to add their transaction to the next block in the blockchain.
To ensure a smooth experience for our customers and reasonable transaction processing times, Coinbase 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 pays may differ from that estimate. All fees we charge will be disclosed at the time of your transaction.
