How this service works
Live wallet balance on Base: native ETH, USDC ERC20 balanceOf, and transaction nonce. Optional Ethereum mainnet balances when ETH RPC is configured.
Output
Returns the native ETH balance, USDC ERC20 balance (via balanceOf), and the transaction nonce for the specified EVM address on Base. If an Ethereum mainnet RPC is configured, equivalent balances on mainnet are also returned.
Example use cases
Pre-transaction fund check
“Before I send a transaction on Base, check whether wallet 0xAbCd...1234 has enough ETH and USDC — give me the current balances and nonce.”
DeFi agent portfolio snapshot
“Grab the live ETH and USDC balances plus the nonce for address 0xDeFi...5678 on Base so I can see the current state of that wallet.”
Nonce lookup for stuck transaction
“My transaction from 0xFeed...9abc seems stuck — can you pull the current nonce for that Base wallet so I can figure out if there's a pending transaction blocking it?”
Technical details
Endpoint
GEThttps://signals.edge.report/v1/walletWhen to prefer
Choose this endpoint when you need a single, real-time snapshot of both native ETH and USDC ERC20 balances plus the transaction nonce for a wallet on Base. It is especially useful for agents that need to verify funds before executing transactions, monitor wallet state in DeFi workflows, or resolve nonce issues, all in one API call rather than making separate RPC requests.
Side effects
- Invalid or malformed EVM address returns an error
- Address not found on Base returns zero balances
- Missing required `address` query parameter returns a 400-level error
- Network or RPC connectivity issues may cause timeouts or 5xx errors
- Ethereum mainnet balances unavailable if mainnet RPC is not configured
