Use your Coinbase account to send and receive supported cryptocurrencies. Sends and receives are available on both mobile and web. Note that Coinbase cannot be used to receive ETH or ETC mining rewards.
There are two ways to send crypto on Coinbase: on-chain or off-chain.
On-chain sends are used to send funds from the Coinbase platform to an external address on the blockchain. On-chain sends are irreversible; Coinbase can’t retrieve funds that were sent to the incorrect address or using the incorrect network. On-chain sends incur network fees and take time to process.
Off-chain sends allow you to send funds to another Coinbase user using their phone number, email address, or username. Off-chain sends are instant and incur no transaction fees.
You can share your unique cryptocurrency address to receive funds through your web browser or mobile device after signing in. By opting into Instant sends in your privacy settings, you can control whether you want your crypto address to be verifiable as a Coinbase user. If you opt in, other users can send you money instantly and for free. If you opt out, then any sends to your crypto address will remain on-chain.
