Domain knowledge for Blockscout — workflow patterns, data models, and gotchas for your AI agent.

Blockscout provides in-depth blockchain analysis capabilities across multiple networks. This service enables deep inspection of on-chain activity, smart contract interactions, and address analytics.

Core Capabilities

Transaction & Block Analysis: Retrieve detailed transaction information with enriched metadata, block data including gas metrics and timestamps, and historical block lookups by date/time. Access native currency transfers and smart contract interactions for any address.

Token & NFT Analytics: Search tokens by symbol or name, get ERC-20 transfer histories with time range filtering, analyze detailed token holdings with market data, and retrieve NFT collections (ERC-721, ERC-404, ERC-1155) owned by addresses.

Smart Contract Inspection: Access verified contract source code and metadata, retrieve contract ABIs, call contract functions (both view and simulated transactions), and inspect contract deployment details.

Address Intelligence: Perform thorough address analysis including existence checks, native token balances, transaction counts, and activity summaries. Support for ENS domain resolution to Ethereum addresses.

Multi-Chain Support: Query available blockchain networks with their chain IDs and access chain-specific data through raw API endpoints.

Domain Model

Addresses serve as the primary entity, with associated transactions, token transfers, NFT holdings, and contract interactions. Blocks contain timestamped transaction batches with gas metrics. Smart contracts expose ABIs and callable functions.

Key Considerations

Session initialization is required before accessing most functionality. Token searches return multiple potential matches requiring verification. Contract function calls are simulated for non-view functions. Some features may be chain-specific or require particular network configurations.
