Zerion
Zerion is a self-custody wallet focused on the EVM ecosystem, with a built-in DeFi portfolio tracker as its flagship feature: it automatically detects positions, debts and rewards across 50+ networks (Ethereum, Polygon, Arbitrum, Optimism, Base, BNB Chain and others), and also supports Solana. Keys stay on the user's device, with optional encrypted backup to iCloud or Google Drive. It integrates DEX-aggregated swaps, a fiat on-ramp, a dApp browser, WalletConnect and Ledger support. The browser extension is open-source (GPL-3.0).
