Zerion

Zerion is a self-custodial crypto wallet and multi-chain portfolio tracker that consolidates holdings, DeFi positions, and transaction history from 58+ blockchains — including Solana — into a single dashboard. The platform has operated on-chain for more than seven years and serves over 10 million wallets across its browser extension, web app, and mobile applications for iOS and Android.

What Zerion Does

The core problem Zerion addresses is fragmentation. A user holding assets across Solana, Ethereum, Base, Arbitrum, and a handful of smaller EVM chains typically needs a different wallet interface for each network and has no unified view of total value, profit and loss, or DeFi exposure. Zerion aggregates all of this into one place: token balances, liquidity positions, staking rewards, and LP tokens across more than 4,500 DeFi protocols are tracked and displayed in real time without requiring users to give up custody of their keys.

Zerion operates entirely as a non-custodial product. Private keys are generated and stored on the user's device; the company does not hold custody. The browser extension's source code is published on GitHub. For users who prefer an additional layer of hardware security, Zerion supports Ledger hardware wallet connections.

Interfaces and Access

Zerion offers four ways to interact with its platform. The browser extension installs into Chrome, Firefox, and other compatible browsers and functions as a full wallet for signing transactions across supported networks. The web application provides portfolio analytics accessible from any browser without installation. The mobile apps for iOS and Android carry the same feature set in a native format and hold a 4.8-star rating on the App Store. All four interfaces share the same underlying account, so positions and history remain consistent regardless of which surface a user accesses.

Trading and DeFi

Within the Zerion wallet, users can swap tokens across supported chains without leaving the interface. The platform aggregates liquidity from multiple decentralized exchanges to route swaps toward the best available price. Cross-chain swaps between different networks are also supported. On Solana specifically, Zerion connects users to the network's decentralized exchange ecosystem alongside the broader set of EVM chains the platform covers.

Beyond basic swaps, Zerion exposes DeFi positions across lending protocols, liquidity pools, and staking contracts. Users can see the underlying composition of complex positions — collateral ratios, accrued interest, unclaimed rewards — directly in the portfolio view. A real profit-and-loss tracker calculates actual returns across tokens, perpetuals, and tokenized real-world assets normalized to USD.

In mid-2026, Zerion introduced xStocks, an integration enabling users to trade more than 600 tokenized stocks — including shares of private and pre-IPO companies — directly from their self-custody wallet. This added an on-chain equities layer to the existing DeFi and crypto capabilities.

Developer Infrastructure: Zerion API

Zerion runs a separate API product that third-party developers can use to access the same normalized multi-chain data that powers the consumer wallet. The API covers seven primary data types: portfolio analytics, DeFi positions, transaction decoding, performance tracking, NFT data, webhook notifications for real-time activity alerts, and token market data.

The infrastructure updates within milliseconds of new blocks being confirmed, which the company describes as eliminating stale data concerns for application developers. The Zerion API is reported to power over 2,000 on-chain products, including integrations built by Coinbase, Uniswap, OpenSea, Safe, and Kraken.

In June 2026, the company launched Zerion Streams, a data feed product built on Apache Kafka that delivers real-time on-chain transactions and pricing data to developers who require streaming data access rather than request-response API calls. Robinhood Chain mainnet support was added to the API the following month, giving developers building on that network access to wallet data through the same interface.

Developer authentication supports standard API keys as well as x402 — a per-request billing protocol that works on Base and Solana without requiring account signup — and Machine Payment Protocol on the Tempo network.

AI Agent Tooling

In May 2026, Zerion released the Zerion CLI, an open-source toolkit that allows AI agents — including Claude, Cursor, and OpenAI Codex — to query portfolio data and execute blockchain transactions via natural language commands. The CLI is built on the Zerion API and supports 40+ EVM chains and Solana. Capabilities include portfolio tracking across 8,000+ DeFi protocols, token swaps, bridge routing, transaction signing, and PnL calculations.

The Zerion CLI is extensible through a modules system called Skills, which allow developers to add new protocol integrations and workflows. At launch, MoonPay, Uniswap, Polymarket, Monad, and LI.FI contributed Skills to the catalog. The CLI also ships with an MCP server enabling direct integration with Claude, Cursor, Windsurf, and VS Code.

Security

Zerion's browser extension and wallet infrastructure have been audited by four independent security firms: Secfault Security, Zokyo, Cure53, and SlowMist. The company makes its audit reports publicly available.

Zerion DNA

Zerion maintains a generative NFT collection called Zerion DNA with more than 369,000 holders. The NFTs function as a reputation layer within the ecosystem and are distributed based on on-chain activity, though the exact mechanics are product-level details beyond what primary sources enumerate here.

How Zerion Fits in the Solana Ecosystem

Zerion's Solana support means users who primarily hold assets on Solana can use the wallet to manage those positions within the same interface they use for EVM chains. The platform handles Solana-native tokens, tracks on-chain activity, and routes swaps through Solana DEX liquidity. The Zerion CLI's Solana support extends this to agentic use cases, where AI tools can manage Solana portfolios and execute transactions programmatically.

For Solana users who also hold positions on Ethereum mainnet, Base, Arbitrum, or other chains, Zerion provides a unified view that no single-chain wallet can offer. That cross-chain coherence — real PnL, aggregated DeFi exposure, and normalized transaction history across all supported networks — is the primary practical argument for using Zerion over a chain-specific alternative.
