How this service works
Native ETH and one ERC-20 balance (default USDC) for an address on Base, raw and formatted. Result carries a signed receipt.
Output
Returns native ETH balance and one ERC-20 token balance (defaulting to USDC on Base) in both raw (wei/smallest unit) and human-readable formatted form, along with a cryptographically signed receipt attesting to the result.
Example use cases
Pre-payment wallet sufficiency check
“Before I send that USDC payment, can you confirm that wallet 0x1234...abcd has at least enough USDC on Base to cover it? Show me the formatted balance with a signed proof.”
Portfolio snapshot for a user address
“What are the current ETH and USDC balances on Base for my address 0xDead...Beef? Give me both the human-readable amounts and the raw values.”
Custom ERC-20 token balance lookup
“Check the balance of token contract 0xA0b8...eB48 for address 0x9876...fedc on Base — I need the raw and formatted amounts with a signed receipt.”
Technical details
Endpoint
POSThttps://hcrb.in/v1/tools/balance-check/call?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single, verifiable on-chain balance check for ETH plus one ERC-20 token on Base, especially when a signed receipt is required for proof or audit purposes. Prefer it over generic blockchain explorers when you need programmatic, structured output with both raw and formatted amounts in one call.
Side effects
- Invalid or malformed EVM address returns an error
- Token contract address not deployed on Base returns zero or error
- Network congestion may cause slow RPC responses
- Non-0x-prefixed address rejected by schema validation
- USDC default may not apply if wrong chain context assumed
