Zerion primary sources — 2026-04-30

Project status in this pass

  • No canonical standalone whitepaper or litepaper surfaced.
  • The clearest current source of truth is Zerion’s first-party site, llms.txt, developer docs, chain-coverage page, pricing page, and security page.

Primary-source snapshots

1) Zerion llms.txt

  • URL: https://zerion.io/llms.txt
  • Key excerpt:
    • Describes Zerion as “a self-custodial crypto wallet and onchain data platform for Ethereum, Solana, Tron, and 40+ other chains.”
    • Explicitly says Zerion ships three things that work together: Zerion Wallet, Zerion Web App, and Zerion API.
    • Says the API is the data layer and the wallet and web app are reference consumers of that same data.
    • This was the highest-signal source in the pass because it prevented cataloging Zerion too narrowly as only a wallet.

2) Homepage

  • URL: https://zerion.io/
  • Key excerpt:
    • Frames Zerion as “Your crypto wallet for Solana and Ethereum.”
    • Says users get “One wallet for all your tokens, DeFi, and NFTs” across Ethereum, Solana, and major EVM networks.
    • Highlights 8,000+ integrated protocols, 51+ networks, non-custodial design, browser extension distribution, a portfolio-tracking app, and the Zerion API.

3) Developer docs introduction

  • URL: https://developers.zerion.io/
  • Key excerpt:
    • Says Zerion API is the fastest way to query wallet portfolios, DeFi positions, transaction history, PnL, NFTs, and webhook-driven activity.
    • Emphasizes normalized multichain responses, freshness within milliseconds of new blocks, and battle-tested infrastructure already powering Zerion’s own products.
    • Also exposes AI-facing surfaces including Zerion CLI, MCP, x402, and MPP references in the docs taxonomy.

4) Supported blockchains page

  • URL: https://developers.zerion.io/reference/supported-blockchains
  • Key excerpt:
    • Documents a broad supported-chain matrix across Ethereum, Solana, Base, Arbitrum, Optimism, Polygon, Avalanche, BNB Chain, Gnosis, zkSync Era, and many newer EVM networks.
    • Splits support into tokens and positions, transactions, DeFi protocols, and NFTs.
    • Reinforces that Zerion is an onchain data infrastructure layer, not only a single wallet client.

5) Pricing page

  • URL: https://developers.zerion.io/pricing
  • Key excerpt:
    • Shows fixed monthly API plans with call ceilings and peak-RPS ceilings.
    • Documents a free Developer tier and paid Builder, Startup, Growth, and Enterprise tiers.
    • Confirms Zerion has a real developer-platform business model, not just a consumer wallet distribution channel.

6) Security page

  • URL: https://zerion.io/security
  • Key excerpt:
    • Repeats that Zerion is self-custodial and cannot access the user’s seed phrase or private keys.
    • Highlights open-source core wallet code, public audits, phishing detection, transaction previews, custom token allowances, and an Immunefi bug bounty.
    • Helps classify Zerion as a security-conscious wallet platform rather than a simple portfolio viewer.

Working conclusion

Zerion is best cataloged as a self-custodial wallet platform plus multichain onchain-data control plane. The first-party materials repeatedly show that the consumer wallet and web app sit on top of the same API Zerion sells to third-party wallets, apps, institutional tools, and AI-agent workflows. In this pass, the llms.txt and developer docs were more revealing than any nonexistent whitepaper.
