A CLI That Talks to Any Smart Contract in Plain English
The article introduces AbiLens, a chat interface for interacting with Ethereum Virtual Machine (EVM) smart contracts using natural language. It explains how AbiLens resolves the contract ABI, builds context for the language model, and translates user queries into contract function calls.
Why it matters
AbiLens simplifies the interaction with smart contracts, making it more accessible to non-technical users and enabling new use cases for decentralized applications.
Key Points
- 1AbiLens uses the whatsabi library to reconstruct the ABI for unverified contracts
- 2It leverages a language model to understand user queries and execute the appropriate contract functions
- 3AbiLens supports multiple EVM chains including Ethereum, Polygon, Optimism, and more
- 4Future plans include adding write support, event log querying, and multi-contract conversations
Details
AbiLens is a tool that allows users to interact with smart contracts using natural language queries. It works by first resolving the contract's Application Binary Interface (ABI), which describes the available functions and their parameters. For unverified contracts, AbiLens uses the whatsabi library to reconstruct the ABI from the contract's bytecode. It then builds a context for the language model, informing it about the available functions. When the user asks a question, the language model decides which function to call and translates the result into a human-readable response. Currently, AbiLens supports multiple EVM chains, and the author plans to add features like write support, event log querying, and the ability to compare data across multiple contracts.
