Smart Contract Interaction

When to Use

• Reading contract state (view/pure functions)
• Writing transactions (state-changing calls)
• Encoding/decoding ABI data
• Deploying contracts (direct or via factory)
• Working with proxy patterns (EIP-1967, UUPS, Transparent)
• Batching reads with Multicall3

Prerequisites

• MCP: blockchain-rpc-server
• MCP: defi-protocol-server for known protocol ABIs
• MCP: security-audit screening for unknown contracts
• Guardrails: verify contract before interaction
