Coinbase charges a commission on staking rewards earned by users. The commission rate varies by asset and is disclosed prior to participation in staking.
Staking commission reduces your effective annual yield and should be factored into any comparison of staking returns across different platforms or protocols.
Coinbase's dual-fee structure means retail users pay both an embedded spread (up to 2% of transaction value) and a separate explicit transaction fee on every buy or sell, making the true cost of trading higher than either charge alone suggests. Users paying with debit cards or instant bank transfers face significantly higher fees than those using standard ACH transfers, which can materially affect the economics of small or frequent trades. You can see your exact total fees β including the spread β by clicking the 'Preview' button before confirming any transaction in the Coinbase app or website.
