How this service works
Identify an address: EOA vs contract, token standard (ERC20/721/1155), proxy, metadata.
Output
A JSON object containing the token/contract name, symbol, type (e.g. 'contract'), and an array of tags describing standards and patterns (e.g. ['ERC-20', 'proxy(EIP-1967)'])
Example use cases
Quick safety check on unknown token
“I just received a token at 0x6B175474E89094C44Da98b954EedeAC495271d0F in my wallet. Can you tell me what it is, what standards it follows, and if there's anything suspicious about its architecture?”
Verify DeFi contract before interaction
“Before I interact with this contract at 0x1f9840a85d5aF5bf1D1762F925BDADdC4201F984, can you explain what it is, show me its name and symbol, and let me know what kind of contract patterns it uses?”
Audit token implementation patterns
“I'm reviewing a portfolio of token contracts and need you to identify which ones use proxy patterns and what standards each implements. Start with 0x7Fc66500c84A76Ad7e9c93437E434122A1f9AcDe and tell me its details and architectural tags.”
Technical details
Endpoint
POSThttps://eltociear-tokenguard.hf.space/explainWhen to prefer
Use this endpoint when you need a human-readable explanation of what a smart contract is — its token name, symbol, contract type, and architectural tags — especially for ERC-20 safety checks or quick on-chain due diligence on an unknown address. Prefer this over raw blockchain RPC calls when you want structured, interpreted metadata rather than raw ABI data.
Side effects
- Invalid or non-existent contract address returns error or empty response
- Non-ERC-20 contracts may return incomplete metadata
- Address on unsupported chain returns no data
- Micropayment via x402 fails if wallet has insufficient USDC balance on Base
- Rate limiting or Hugging Face Space cold-start latency
