Data verified on unchanged since the sources
Worth it if you want a self-custody wallet with a built-in DeFi portfolio tracker (positions, debts, rewards) across 50+ EVM networks plus Solana, open-source extension.
Avoid it if you hold Bitcoin (support unconfirmed) or want consistent audit transparency: the auditor signer lists diverge between the official site and the GitHub repo.
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).

In its favour: built-in DeFi portfolio tracker (positions, debts, rewards) across 50+ EVM networks plus Solana; open-source browser extension (GPL-3.0); IP stored hashed and retained max 14 days. The trade-off to weigh: eVM/DeFi-focused: no confirmed Bitcoin support; the lists of audit firms differ between the official site and the GitHub repo.
