Monad is where builders go to ship faster and scale bigger. It combines EVM familiarity with next-gen speed, so you can use the tools you know while unlocking performance that makes new dapps possible. 

In this guide, we’ll show how you can leverage Zerion API to get fully interpreted, ready-to-use data for Monad apps. Instead of parsing raw blockchain data, you can focus on building amazing user experience with tokens, DeFi positions, portfolios, and more.

What Makes Monad Different

Monad stands out from other EVM ecosystems thanks to its parallel execution architecture.

This means higher throughput, 1000x faster transactions, and near-zero gas fees. 

But you already know that. 

Besides speed, what sets Monad apart is the strength of its community and ecosystem. Millions of wallet addresses are already active on Monad testnet. A whole range of ecosystem initiatives to help builders create apps for these users. 

For users and builders alike, exploring Monad starts with a wallet. 

Wallets for Monad

As Monad gains adoption, more and more wallets are expanding support for the network. MetaMask, Phantom, and all the usual suspects already support the Monad testnet. 

If you’re looking for the fastest and most comprehensive way to explore Monad, Zerion Wallet should be your choice. 

Zerion Wallet doesn’t just connect to Monad. It also offers native portfolio tracking, giving users and developers a simple way to interact with the chain.

Getting Blockchain Data on Monad

One key difference between Monad and Ethereum is that full nodes do not provide access to an arbitrary historical state. Monad’s high throughput means it would require too much storage. 

Luckily, all leading onchain data providers support Monad. 

When building on Monad, you can choose between raw data and ready-to-use data:

  • Raw Data: Node providers like Alchemy and indexers like Goldsky let you query tokens, transactions, and logs directly from the chain. This is great for custom infrastructure and advanced analytics.
  • Ready-to-Use Data: Zerion API for Monad interprets the financial meaning of onchain data. It abstracts away raw blockchain details and returns wallet positions, DeFi portfolios, charts, transactions, PnL, and more. All without needing to run nodes or decode contract interactions. Zerion API maintains sub-second latency with 99.9% uptime. 

Fully interpreted onchain data with Zerion API 

With Zerion API, you don’t need to worry about infra overhead or blockchain plumbing.

  • No infra to run — everything is hosted and indexed.
  • No blockchain skills required — endpoints return human-readable portfolio data, ready to be used in production.
  • Fast integration — Rest API with clear docs and SDKs.

Let’s look at what you can do with Monad data using Zerion API.
