How this service works
Classify up to 50 EVM addresses at once: regular wallet (EOA), EIP-7702 delegated wallet or contract, with code size. Filter airdrop lists, spot contracts or bots. 12 chains.
Output
Returns a JSON object with the chain name, a summary count of contracts vs EOA wallets, and an array of objects for each input address showing: the address, its type (wallet/EOA, contrato, or EIP-7702), and the code size in bytes (0 for EOAs).
Example use cases
Airdrop list bot and contract filter
“I have a list of 40 addresses I want to airdrop tokens to on Base — can you check which ones are real user wallets vs smart contracts or bots so I can filter the list before sending?”
EIP-7702 delegation detection
“Can you check these 20 Arbitrum addresses and flag any that are EIP-7702 delegated wallets so I know which ones have upgraded account abstraction features?”
DeFi protocol recipient validation
“Before we whitelist these 30 addresses on Polygon for our protocol, can you run them through a classifier to confirm which are EOA wallets and which are contracts, including their code sizes?”
Technical details
Endpoint
POSThttps://api.vextorium.com/tipo-direcciones-pago?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to classify EVM addresses across 12 major chains in batch (up to 50 at once), especially for airdrop filtering, bot detection, or distinguishing EOAs from contracts. It uniquely supports EIP-7702 delegated wallet detection, making it more current than generic address classifiers. Prefer it over on-chain RPC calls when you need fast, multi-chain batch classification without managing RPC connections yourself.
Side effects
- Invalid EVM address format returns error or null entry
- Unsupported chain name causes rejection — must be one of the 12 supported enum values
- Batch size exceeding 50 addresses may be rejected
- Network connectivity issues with the target chain can cause timeouts
- Missing required 'direcciones' field returns validation error
