Enables semantic queries against blockchain state across 2000+ EVM and non-EVM chains through a unified query interface. The MCP server abstracts chain-specific RPC endpoints and data formats, translating natural language or structured queries into chain-native calls (eth_call, eth_getLogs, contract state reads) and normalizing responses into consistent JSON structures. Supports batch querying across multiple chains simultaneously with automatic failover to alternative RPC providers.

Deploys compiled smart contracts to any of 2000+ blockchains and generates type-safe contract interaction methods through ABI parsing. The MCP server accepts contract bytecode, constructor arguments, and deployment parameters, submits transactions to the target chain, and returns deployment receipts with contract addresses. Post-deployment, it provides function calling capabilities that encode contract calls, estimate gas, and execute read/write operations with automatic nonce management and transaction signing delegation.

Analyzes deployed smart contracts by fetching and parsing their ABIs from on-chain sources (contract creation bytecode, verified sources on block explorers) or user-provided ABI JSON. Generates human-readable contract documentation including function signatures, state variables, events, and access control patterns. Supports ABI comparison across contract versions and chain deployments to identify breaking changes or inconsistencies.

Executes blockchain transactions (contract calls, token transfers, custom payloads) with automatic nonce management, gas estimation, and receipt polling. The MCP server accepts transaction parameters (to, data, value), submits them to the target chain, and monitors confirmation status with configurable polling intervals. Supports transaction batching and multi-step workflows where subsequent transactions depend on prior confirmations. Integrates with external signers (wallets, key management services) for transaction authorization.

Fetches token and NFT metadata, ownership, and transfer history across 2000+ blockchains through a unified interface. The MCP server queries contract state and event logs to retrieve token balances, allowances, NFT ownership, and collection metadata. Supports batch queries for multiple tokens/NFTs and automatic metadata enrichment from IPFS and external sources. Handles both standard (ERC-20, ERC-721, ERC-1155) and non-standard token implementations with fallback strategies.

Manages the MCP server's initialization, configuration, and resource lifecycle through standard MCP protocol handlers. The server exposes configuration endpoints for setting API keys, RPC endpoints, and chain preferences. Implements automatic health checks and provider failover logic to ensure reliable blockchain connectivity. Supports dynamic reconfiguration without server restart, enabling AI agents to switch chains or update credentials at runtime.

Routes transactions across multiple blockchains and optimizes execution based on gas prices, liquidity, and confirmation times. The MCP server analyzes transaction parameters (amount, token, destination) and recommends the most cost-effective chain for execution. Supports bridge-assisted transactions where assets are moved across chains before execution. Includes gas price forecasting and dynamic fee adjustment to minimize transaction costs.

Queries and decodes smart contract events across 2000+ blockchains by filtering logs based on contract address, event signature, and indexed parameters. The MCP server fetches raw logs from the blockchain, decodes them using contract ABIs, and returns structured event data with human-readable parameter names and types. Supports complex filtering (multiple topics, block ranges, address filters) and batch queries across multiple contracts. Handles event signature hashing and topic encoding automatically.

Integrates with account abstraction (AA) wallets and smart contract wallets (e.g., Safe, Gnosis, ERC-4337 implementations) to enable transaction execution through non-EOA accounts. The MCP server abstracts wallet type detection and generates appropriate transaction payloads for AA wallets (UserOps) or smart contract wallets (batched calls). Supports multi-signature wallets with automatic signer coordination. Handles gas sponsorship and paymaster integration for gasless transactions.
