Backpack
Wallet · 1.7% round trip. Backpack Wallet is a self-custodial multi-chain wallet (Solana, Ethereum, Arbitrum, Optimism, Polygon, Base, Sonic and more) from Backpack Technologies Ltd., with built-in swaps and bridging at a flat 0.85% swap fee. The same company group runs Backpack Exchange, a separate KYC'd centralized exchange regulated in the EU through Backpack EU, which Backpack says returned funds to 110K former FTX EU clients in September 2025.
