Backpack
Backpack is a Solana-first crypto company founded by Armani Ferrante and Tristan Yver — the same team behind Coral and the Anchor framework that powers a majority of Solana programs. It operates two flagship products: Backpack Wallet, an open-source self-custodial multichain wallet (Solana, Ethereum, Bitcoin) with an xNFT plugin runtime, available as a Chrome/Brave extension and iOS/Android app; and Backpack Exchange, a fully fledged centralized exchange offering spot, perpetual futures, dated futures, prediction markets, borrow/lend, RFQ, strategies, vaults, and securities, with a comprehensive ED25519-signed REST + WebSocket API documented at docs.backpack.exchange. Backpack Exchange acquired and processes FTX EU claims and is one of the more technically transparent venues to emerge post-FTX.
