How this service works
Balance of an EVM address on seven more chains: BNB Chain, Avalanche, Gnosis, Linea, Scroll, Sonic and Unichain: native coin, USDC and USDT, plus nonce (transactions sent) on each.
Output
A JSON object containing an array of per-chain results, each with the chain name (red), USDC balance, USDT balance, nonce (number of transactions sent), native coin symbol (nativo), and native coin balance (saldo_nativo). Also includes the queried address and the data source (public RPC nodes via publicnode.com).
Example use cases
Portfolio snapshot across alt-EVM chains
“Give me the full balance breakdown — native coin, USDC, USDT, and nonce — for my wallet 0xAbC123...456 on all seven chains: BNB, Avalanche, Gnosis, Linea, Scroll, Sonic, and Unichain.”
Verify funds before a cross-chain transfer
“Before I bridge, can you check whether 0xF977814e90dA44bFA03b6295A0616a897441aceC has any USDT or USDC sitting on Scroll or Linea?”
Whale wallet activity monitoring
“Look up the balances and transaction nonce for 0xF977814e90dA44bFA03b6295A0616a897441aceC on BNB Chain and Avalanche — I want to see how active this wallet has been and what stablecoins it's holding.”
Technical details
Endpoint
POSThttps://api.vextorium.com/saldo-otras-redes-pago?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need balances specifically on the secondary EVM chains (BNB Chain, Avalanche, Gnosis, Linea, Scroll, Sonic, Unichain) rather than the primary chains (Base, Ethereum, Arbitrum, Optimism, Polygon). If you need all 12 chains at once, use the sibling all-chains endpoint. Choose this endpoint when you only care about a subset of these seven chains and want to filter via the optional 'redes' parameter.
Side effects
- Invalid or malformed EVM address returns an error or null balances
- Unsupported chain name in the redes array is silently ignored or returns null
- Public RPC node downtime may cause null or missing data for specific chains
- Network timeout on slow chains (e.g. Scroll, Linea) may produce incomplete results
- Missing required 'direccion' field causes a validation error
