The short answerZerion answers the question most wallets ignore: what do I hold across every chain, and what did I actually do last month. The portfolio and history views are the best in the category, and they run server-side, which means your addresses and activity are visible to the company.

What we liked, and what fell short
Liked- Best-in-class multi-chain portfolio and history view
- Watch-only address support alongside full wallet functions
- Clean simulation and approval management
Fell short- Portfolio features require sharing addresses with Zerion's backend
- Swap pricing is average rather than best-execution
Why the marks landed where they did
Wallets show balances. Zerion shows a portfolio: positions across dozens of chains including DeFi deposits, LP positions and staked assets, with a readable transaction history that labels what each interaction did. For anyone whose activity spans more than two chains, that view is genuinely hard to reconstruct any other way.
Wallet features
Standard self-custody with seed or hardware key storage, transaction simulation, approval management, swaps and bridging routed through aggregators, and watch-only mode for tracking addresses you do not control — useful for monitoring a hardware wallet or a Safe without exposing keys.
The privacy trade-off
Portfolio construction happens on Zerion's servers, which means the company sees which addresses you track and what they hold. That is the standard architecture for this kind of product and it is a real disclosure: your on-chain activity is public anyway, but linking multiple addresses to one user profile is information you are choosing to hand over.
Costs
The wallet is free; swaps carry routing fees comparable to other in-wallet swap features, which is to say more than going direct to an aggregator.
Who should use it
Multi-chain users who want a single accurate view of their positions, and anyone tracking several wallets. Users prioritising privacy should use Rabby with a local-only setup and accept a worse portfolio view.
FAQ
Is Zerion a custodial wallet?+
No. Keys stay on your device or hardware wallet. What runs server-side is the portfolio analysis, not custody.
Does Zerion see my addresses?+
Yes. Portfolio and history features require sending your addresses to its backend, which links them to one profile.
How many chains does Zerion support?+
Dozens, including Ethereum and its major L2s, with DeFi position tracking rather than just token balances.
Can I use Zerion to watch a wallet I do not control?+
Yes. Watch-only mode tracks any address, which is useful for monitoring hardware wallets or Safe accounts without exposing keys.
