What is Blockchain.com Wallet
Blockchain.com Wallet is the wallet in the Blockchain.com app, which combines a custodial Blockchain.com Account for buying, selling and earning with a non-custodial DeFi Wallet where users hold their own keys. Blockchain.com began work in 2011 with the original Bitcoin block explorer.

| Custodian | Blockchain.com Account (trading, rewards, staking): custodial; keys for custodied funds are kept by Blockchain.com in FIPS 140-2 devices. |
