How this service works
Deterministic Base contract facts: ERC-20 metadata, proxy slots, owner(), privileged-function selectors and flags. Not a safety verdict. Result carries a signed receipt.
Output
A structured payload containing ERC-20 token metadata (name, symbol, decimals, total supply), detected proxy storage slots, the owner() address if present, identified privileged-function selectors and associated flags, and a cryptographically signed receipt confirming the deterministic on-chain read. No safety verdict or ML inference is included.
Example use cases
DeFi token due diligence before investing
“Before I buy into this Base token at 0x4200000000000000000000000000000000000006, can you pull all the on-chain contract facts — proxy slots, owner, any privileged functions — and give me a signed receipt of what you find?”
Audit smart contract upgrade risk
“I need to know if this ERC-20 contract on Base at 0xd9aAEc86B65D86f6A7B5B1b0c42FFA531710b6CA is a proxy and who holds the owner or admin role — fetch the deterministic contract facts with a signed receipt.”
Verify token contract for wallet integration
“We're integrating a new Base ERC-20 at 0x50c5725949A6F0c72E6C4a641F24049A917DB0Cb into our wallet — check its metadata, proxy configuration, and privileged selectors and send back the signed receipt so we can log it.”
Technical details
Endpoint
POSThttps://hcrb.in/v1/tools/token-contract-risk/call?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need raw, deterministic, verifiable on-chain facts about a Base mainnet ERC-20 contract — particularly proxy configuration, ownership, and privileged function selectors — without any ML-based safety scoring. It is ideal when auditability matters (signed receipt) and you want facts, not opinions. Prefer it over general blockchain explorers when you need structured, machine-readable output and a receipt for downstream verification.
Side effects
- Invalid or malformed contract address (not 0x + 40 hex) returns a validation error
- Contract address is not on Base mainnet or does not exist returns a not-found or empty-result response
- Address is an EOA (non-contract) rather than a contract returns an error or empty contract facts
- Chain parameter set to something other than 'base' returns an unsupported-chain error
- Network or RPC timeout may cause a retrieval failure
