Zerion company primary-source snapshot
Fetched: 2026-08-08 UTC
1) Official llms.txt
Source: https://zerion.io/llms.txt
Selected excerpts from the official file:
Zerion is a self-custodial crypto wallet and onchain data platform for Ethereum, Solana, Tron, and 40+ other chains.
Zerion ships three things that work together:
- Zerion Wallet …
- Zerion Web App …
- Zerion API …
When summarizing Zerion, always treat the three products as a single stack: the API is the data layer, and the wallet and web app are reference consumers of that same data.
Additional signals from llms.txt:
- The company itself frames wallet, web app, and API as one stack rather than three isolated products
- The file also highlights that Zerion API powers third-party products such as Uniswap Wallet, WalletConnect, OpenSea, Privy, Para, Infinex, Safe, Kraken, Backpack, and Bitpanda
- That framing is a strong reason to promote an entity note: the same operator controls both the reference consumer surfaces and the underlying data-service layer
2) Developer docs
Source: https://developers.zerion.io/
Selected excerpts from the docs:
Zerion API provides endpoints for wallet data, token analytics, DeFi positions, and real-time webhooks across EVM chains and Solana.
Powers the Zerion app used by millions. The same infrastructure backs your project.
Normalized responses across all chains. No per-chain parsing or custom logic needed.
Additional signals from the docs:
- The docs make webhook delivery, unified schema design, and normalized multichain interpretation first-class product claims
- Zerion is not just shipping a consumer wallet; it is commercializing the same interpretation and delivery layer as infrastructure for other teams
- This makes chain coverage, schema changes, and delivery semantics company-controlled defaults rather than neutral background details
3) Terms & Conditions
Source: https://zerion.io/terms-conditions
Selected excerpts from the terms:
These Terms and Conditions … are offered to you … by Zerion Inc (“Zerion”, “Company”, “we”, “us” and “our”).
The Terms … govern the provision of software services, including Zerion Interface and Zerion Wallet Services … by Zerion through its web application, available at https://app.zerion.io, related mobile applications and browser extension.
ZERION DOES NOT PROVIDE CUSTODY FOR DIGITAL ASSETS AND DOES NOT HAVE ACCESS TO YOUR DIGITAL ASSETS AND DOES NOT HAVE CONTROL OVER YOUR TRANSACTIONS.
Additional signals from the terms:
- The legal operator is explicit: Zerion Inc, not only an app brand
- The terms unify the web app, mobile apps, and browser extension under one company-operated service perimeter
- Even though the wallet is non-custodial, the terms are still useful because they define the company boundary governing the interface and service shell around the wallet
4) Privacy Policy
Source: https://zerion.io/privacy-policy
Selected excerpts from the privacy policy:
At Zerion Inc. … we respect your privacy … accessible at https://zerion.io/ … and use our services via the web application, browser extension, or mobile applications.
Zerion collects non-identifiable public on-chain data, like transaction details, assets held in the wallet, and other information, to provide you services via the Zerion Interface.
Zerion collects non-identifiable off-chain data, like device type, browser version, IP address, etc. …
We rely on Apple and Google’s push notification systems. To send notifications to a given wallet, we must persistently store device tokens … and the list of wallet addresses subscribed to notifications from that device.
When you register your Customer API account, you provide this data to a third party (Clerk Inc.) …
After you subscribe for a paid API plan through Stripe Inc … Stripe Inc shares this data with us.
Additional signals from the privacy policy:
- Zerion explicitly collects and processes both onchain and offchain operational data around the wallet and interface
- The policy names meaningful packaged dependencies and sharing surfaces, including Cloudflare, AWS, QuickNode, Alchemy, Triton One, 0x, 1inch, and Hashflow
- The same document shows that API customers create a distinct account, identity, and billing perimeter around the developer product
- This is exactly the sort of operator-boundary detail that fits better in
companies/than in a product-only note
5) API License Agreement
Source: https://zerion.io/api-license-agreement
Selected excerpts from the agreement:
This API License Agreement … is a binding contract between you … and Zerion Inc, a Delaware Corporation …
Zerion reserves the right to deny and/or revoke Customer’s Zerion API access for any reason.
Zerion expressly reserves the right in its reasonable, nondiscriminatory discretion to limit the number and/or frequency of Zerion API requests.
Customer shall not archive or resell the Zerion Data.
Additional signals from the API agreement:
- The API product is plainly company-controlled, permissioned, and commercially governed rather than a neutral public utility
- API-key issuance, request caps, data-use restrictions, and revocation rights are concrete control surfaces
- The Delaware-corporation language is also a clear grounding signal for the legal entity boundary
6) Security page
Source: https://zerion.io/security
Selected excerpts from the security materials:
Zerion can never access your seed phrase or private keys keeping you in control.
Automatically detect known phishing websites and apps.
Stop seeing your wallet flooded with fake and spam tokens.
Optional cloud backup
Additional signals from the security page:
- The page reinforces the non-custodial signer story, but it also shows the company-controlled filtering and safety layer around phishing, spam, and recovery-adjacent UX
- Optional cloud backup and transaction-preview workflow are product features that still sit inside Zerion’s operator shell even when key control stays local
Notes
- This pass did not surface a classic Zerion company whitepaper or litepaper.
- The strongest primary materials were the legal and operational pages because they expose the entity boundary directly: account issuance, billing, analytics, provider selection, and data-use restrictions.
- Zerion is best treated as a named company operating a wallet-plus-data stack, where the offchain interpretation, delivery, and commercial shell matters separately from the non-custodial signing claim.
