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 a count of addresses checked and an array of results per address, including contract bytecode analysis, token authority details (mint/freeze controls for SPL tokens), and multi-DEX liquidity risk indicators across the supported chains (Base, Solana, Ethereum, Arbitrum, Optimism, Polygon, BNB Smart Chain).

Example use cases

Pre-trade rug-pull detection on Base

“I'm about to buy a new token on Base with contract address 0xd3adb33f... — can you check the bytecode and liquidity risk before I put money in?”

SPL token authority check on Solana

“Can you verify the mint authority and freeze authority for this Solana token at address So11111...abc before I swap into it on Jupiter?”

Multi-chain token safety scan for portfolio

“I have three tokens I'm considering: one on Arbitrum at 0xarb123..., one on Polygon at 0xpoly456..., and one on BNB Chain at 0xbnb789... — can you run a pre-trade contract and liquidity risk check on all three?”

Endpoint

POSThttps://piggybank.loth2023ys.workers.dev/v1/batch?utm_source=zero.xyz

When to prefer

Choose this endpoint when you need pre-trade verification across multiple blockchains simultaneously, especially when assessing both EVM-compatible chains (Base, Ethereum, Arbitrum, Optimism, Polygon, BNB Chain) and Solana in a single call. It is particularly valuable for agents executing DeFi trades that need to check for honeypot contracts, suspicious token authority, or insufficient DEX liquidity before committing funds.

Side effects

Invalid or malformed contract/token address returns error in results array
Unsupported chain not among the 7 supported networks may return null or error
Network congestion or RPC unavailability on a specific chain may cause partial results
Empty addresses input returns count 0 with empty results
Payment failure via x402 v2 results in 402 response before processing
