Monad Network Snapshot
Monad is a high-performance Layer-1 blockchain designed to bring CEX-level throughput without sacrificing Ethereum compatibility. Built around parallel execution, Monad targets 10,000+ TPS, sub-second block times, and seamless EVM equivalence.
For developers, Monad feels like building on Ethereum, but with drastically more headroom. Existing Solidity contracts run out-of-the-box, gas costs are significantly lower, and the network is designed for parallel execution of transactions at scale. This makes Monad ideal for exchanges, prediction markets, agentic applications, and any workload where speed and efficiency determine user experience.
With Zerion API, developers can instantly fetch wallet balances, positions, NFTs, transactions, and prices on Monad — no node setup required.

FAQ
You can fetch all ERC-20 and native MON balances on Monad using Zerion API's positions endpoint, which normalizes assets, prices, and metadata so you don’t need to index Monad tokens yourself.
Yes. Zerion API's transactions endpoint supports Monad from day one. You’ll receive normalized transfers, swaps, approvals, and interactions across all supported dApps — without running your own Monad node or indexer.
Zerion’s indexer automatically ingests and maps new token contracts on Monad. Most new tokens appear within minutes, and wallet positions are added as soon as tokens become available.
