Etherscan Opens On-Chain Data to AI Agents Across 60+ EVM Chains
Etherscan's 'Build with AI' suite gives AI agents direct API access to verified on-chain data across 60+ EVM chains, using MCP, CLI, and Skills tools to reduce LLM hallucinations.
Block explorer Etherscan said it has launched a tool suite called “Build with AI” that gives artificial intelligence agents and coding assistants direct access to real-time on-chain data through its official API. The integration covers more than 60 networks compatible with the Ethereum Virtual Machine.
Etherscan announced the rollout in a post on X on August 31. The suite uses the Model Context Protocol, along with command-line interface tools and specialized “Skills” modules for tracking fund flows and auditing smart contracts. By pulling verified logs, balances, and transaction data directly from Etherscan’s indexed databases, the system is designed to reduce the risk that large language models will produce fabricated outputs, a known problem in automated crypto analysis, where bots increasingly rely on AI-generated summaries.
“Give your agents direct and structured access to reliable onchain data,” Etherscan said in the post. The toolset, the company added, lets developers build financial agents that operate across the multi-chain ecosystem without relying on unverified third-party sources.
Etherscan has long served as a primary front-end for blockchain explorers, but its API was primarily used by human developers and traders. The “Build with AI” suite formalizes the query layer for autonomous software, offering structured machine-readable access to balances, transaction logs, and smart-contract states. The platforms covered include Ethereum mainnet, Polygon, Arbitrum, Optimism, BNB Chain, and dozens of other EVM-compatible chains.
The move comes as the crypto sector pushes toward automated agent-to-agent transactions. Coinbase introduced its own AiFi framework in recent weeks, and Fidelity Digital Assets published a report warning that AI agents could introduce new risks to blockchain infrastructure. Etherscan’s toolset aims to fix the data-fidelity layer: agents that can cross-reference on-chain activity against a trusted provider are less likely to act on hallucinated contract addresses or fake transaction histories.
Developers can integrate the official MCP server and CLI tools to build automated compliance checks, real-time portfolio trackers, or hedge bots that execute on verified on-chain signals. The suite is available immediately for all 60+ supported chains.
