Backpack
Coral
Backpack is a multichain self-custody wallet built by Coral, founded by Armani Ferrante (creator of Solana's Anchor framework). Originally a Solana-native wallet, it also supports Ethereum and Sui, and is best known for xNFTs: tokenized executable apps that run inside the wallet via a built-in app store. Private keys stay on the user's device, protected by a seed phrase, and Coral has no access to funds.
