Information Density — The Lens

Classify each sentence as substantive or hollow. Grounding markers — numbers, currencies, dates, technical units, named entities — outweigh marketing adjectives. When fluff sits right next to hard evidence, the fluff is forgiven.

Info Density Power-words vs. Substance ratio.

The information density is exceptionally high, particularly on the API sub-page which lists specific pricing tiers ($149/month for 250K requests) and technical limits (150-1000 RPS). While the Homepage contains some fluff like ‘Browse The New Internet’ (H1) and ‘One Wallet. Layers of Possibilities’ (H2), the body text quickly anchors these claims in specific functionality, such as support for 50+ chains and specific audit firms like Trail of Bits and Peckshield. The ratio of marketing power words to hard technical specifications is heavily weighted toward substance.

Information Density is read straight from the body copy: how much of the text carries grounded, checkable substance versus hollow filler. Below is the clean text the engine analyzed, then the industry’s known generic-claim patterns to weigh it against.

[H2] FAQ
[H3] Is Zerion Wallet safe?
Zerion is a non-custodial wallet audited by professional security firms, including Cube53, Secfault Security, Peckshield, and Trail of Bits. All security audits are public. Zerion Wallet’s core code base is open-sourced. A bug bounty with Immunefi is there to reward whitehat hackers who might uncover any additional vulnerabilities. So, it’s fair to say that Zerion Wallet is safe.
[H3] How do I transfer money to Zerion crypto wallet?
You can send assets from any crypto exchange or a crypto wallet app. To transfer crypto from an exchange, click withdraw in your exchange or ‘send’ in your and wallet app and enter the address of your Zerion crypto wallet. You can also buy crypto in Zerion Wallet: just tap the blue button in the center of your screen, select ‘Buy’, and you will be taken to the dialogue window where you can buy crypto with a credit or debit card. Please note that you will not be able to transfer crypto from Revolut, PayPal or a similar neobank that does not offer crypto withdrawals.
[H3] Can I create wallets for different chains in Zerion Wallet?
A wallet created with Zerion Wallet automatically works with all supported networks that are compatible with Ethereum. This includes Arbitrum, Binance Smart Chain, Polygon, Optimism, Fantom and more.
[H3] Can I make money with Zerion Wallet?
Zerion Wallet is a non-custodial wallet for crypto that gives you access to a broad range of opportunities across DeFi and NFTs. With Zerion Wallet you can easily lend out your cryptocurrency and generate a yield. You can also provide liquidity and earn trading fees. In some protocols you can write options and earn premiums. Your Zerion Wallet will track all these positions and neatly show you your rewards.  You can also trade tokens in your Zerion crypto wallet, automatically sourcing the best price from across various decentralized exchanges. Your Zerion Wallet will calculate your costs and profits.
[H3] How does trading work with Zerion crypto wallet?
Zerion Wallet automatically sources the best cryptocurrency prices from across different decentralized exchanges (DEXes) such as Uniswap, 1Inch, Balancer, or Sushiswap. This is done using DeFi SDK, the open-source library developed by Zerion to integrate with leading DeFi protocols. In practice, when swapping tokens in Zerion Wallet, you’ll get the best price that is currently available on various DEXes.
[H3] Does Zerion offer DeFi portfolio tracker and where to find it?
Yes, Zerion Wallet offers a built-in DeFi portfolio tracker, which automatically finds and tracks all your DeFi positions, debts, and rewards. You can find all your DeFi portfolio by tapping the ‘Tokens’ section and then changing the layout to ‘By Platform’ to arrange your assets by protocol. Zerion integrated DeFi tracking for over 500 protocols so it’s very likely that your DeFi assets will be tracked.
[H3] What is the best free crypto portfolio tracker?
The best crypto portfolio tracking depends on what exactly you need to track. Zerion Wallet offers a free portfolio tracker for DeFi and NFTs: it automatically finds and tracks all your tokens. However, this only works for non-custodial wallets, and Zerion will not be able to show assets you own on centralized exchanges.
[H3] How do I track my DeFi coins?
Zerion Wallet automatically tracks all DeFi coins you own. There is no need to add any token or coin manually, they will all show up in the ‘Tokens’ section of your wallet. To see how DeFi tracking works with Zerion, you can first connect your existing wallet and Zerion will automatically track DeFi coins. Zerion crypto wallet tracks all major coins listed on Coingecko as well as any other ERC-20 (for new assets you might see a warning and would need to double check the coin’s smart contract).
[H3] How to track staked DeFi tokens, LPs, and rewards?
In Zerion Wallet, staked tokens, LPs, rewards, debts, and other DeFi positions are automatically tracked. Zerion Wallet’s built-in DeFi tracker can be found in the ‘Tokens’ section of your wallet. If your DeFi positions have any earned and unclaimed rewards, Zerion Wallet will list them in your DeFi dashboard. If you see that, you can go ahead and claim those rewards in the protocol.
[H3] Can Zerion crypto wallet hold Bitcoin?
Zerion Wallet currently does not support Bitcoin. However, you can buy WBTC or wrapped Bitcoin. These are ERC-20 tokens that represent locked BTC and closely track the price of Bitcoin.

[H2] FAQ
[H3] Is Zerion Wallet safe ?
Zerion is a non-custodial wallet audited by professional security firms, including Cube53, Secfault Security, Peckshield, and Trail of Bits. All security audits are public. Zerion Wallet’s core code base is open-sourced. A bug bounty with Immunefi is there to reward whitehat hackers who might uncover any additional vulnerabilities. So, it’s fair to say that Zerion Wallet is safe.
[H3] Can Zerion access my seed phrase ?
No. Zerion is non-custodial. Your seed phrase is stored locally on your device so Zerion does not have access to this data.
[H3] Does Zerion store my seed phrase in iCloud ?
On mobile, Zerion offers an encrypted backup for your seed phrase using iCloud (for iPhones) or Google Drive (for Android phones). It’s entirely optional. If you choose to use the cloud backup, you’ll need to create a safe password to encrypt your seed phrase. Importantly, Zerion will never be able to access your seed phrase — or restore it if you forget the password.
[H3] Which encryption does Zerion use ?
For iCloud and Google Drive backups, Zerion uses encryption from Apple or Google. It’s entirely optional. If you decide to use this, you will need to set up an encryption password with a minimum of 14 characters with numbers, symbols, and mixed case letters.
[H3] What is the safest way to create and store my seed phrase?
For an additional layer of security, you can create your seed phrase via a Ledger crypto wallet and then easily connect it to Zerion Wallet, both the extension and the mobile app.
[H3] Can Zerion recover my password?
No, the password is not stored anywhere in the Zerion database, so only you know it. This also means we cannot restore your password if you forget it. You would then need to reinstall the app and import your wallets. This is the responsibility that comes with self-custody.
