How this service works
One address across five EVM chains (Base, Ethereum, Arbitrum, Optimism, Polygon): native coin and USDC balance per chain and total USD value.
Output
A JSON object containing the wallet address, a per-chain breakdown (indexed by network name) with native coin balance and USDC balance for each of the five chains (Base, Ethereum, Arbitrum, Optimism, Polygon), an approximate total USD value aggregated across all chains, and an optional note field.
Example use cases
Portfolio snapshot for DeFi user
“Can you check the total balance across all five EVM chains — Base, Ethereum, Arbitrum, Optimism, and Polygon — for wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045? I want to see native coin and USDC per chain plus the combined USD value.”
Due diligence on a counterparty address
“I need to verify the holdings of this wallet before sending funds — can you look up the native and USDC balances on Ethereum, Base, Arbitrum, Optimism, and Polygon for 0xAb5801a7D398351b8bE11C439e05C5B3259aeC9B and tell me the total USD value?”
Automated treasury monitoring
“Check the current multi-chain balance for our treasury wallet 0x71C7656EC7ab88b098defB751B7401B5f6d8976F across Base, Ethereum, Arbitrum, Optimism, and Polygon — I need the native coin amounts, USDC on each network, and the total USD figure.”
Technical details
Endpoint
POSThttps://api.vextorium.com/saldo-multired-pago?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single-call multi-chain view of both native coin and USDC balances aggregated into a USD total across Base, Ethereum, Arbitrum, Optimism, and Polygon. Prefer it over single-chain balance endpoints when the user's portfolio spans multiple EVM networks and you want one unified response rather than five separate calls.
Side effects
- Invalid or malformed wallet address returns an error or null fields
- Rate limiting or payment failure results in a 402 or 429 response
- RPC node timeouts on one or more chains may yield partial or null per-chain data
- Non-EVM address formats (e.g. Solana) will fail validation
- Temporary chain congestion may delay responses for specific networks
