How this service works

7-chain pre-trade smart contract bytecode, SPL/Token-2022 authority & multi-DEX liquidity risk oracle across Base (8453), Solana, Ethereum (1), Arbitrum (42161), Optimism (10), Polygon (137), and BNB Smart Chain (56). Instant x402 v2 settlement in Base USDC or BSC USDC.

Output

Returns a JSON object with: burnedPct (percentage of token supply that has been burned), ownerAddress (current owner address, zeroed if renounced), circulatingPct (percentage of supply in circulation), and ownershipRenounced (boolean indicating whether the contract owner is the zero address).

Example use cases

Rug pull check before DEX swap

“I'm about to buy this token on Uniswap on Ethereum — contract is 0xAbCd...1234. Can you check if ownership is renounced and how much of the supply is burned before I put money in?”

Solana SPL token authority audit

“I found a new SPL token on Solana I want to trade. Can you audit the token authority — is it renounced, and what's the circulating vs burned split?”

Multi-chain portfolio safety scan

“I hold tokens on Arbitrum and Polygon and I want to know if any of the contracts still have active owners — can you check ownership renouncement and burn percentage for contract 0x5678...ef on Arbitrum chain 42161?”

When to prefer

Choose this endpoint when you need a fast, cheap ($0.01 USDC) pre-trade safety check spanning ownership renouncement and token burn data across 7 chains simultaneously, especially when operating on Base, Solana, Arbitrum, Optimism, Polygon, or BNB Smart Chain and needing a unified oracle rather than querying each chain's explorer separately.

Side effects

Unsupported chain ID returns an error or empty result
Invalid or non-existent contract address returns no data
RPC node timeouts on congested chains may delay or fail response
Token with non-standard ownership patterns may return inaccurate ownershipRenounced flag
Payment failure via x402 protocol blocks the request
