How this service works

Example use cases
Pre-transaction balance verification
“Before I send a payment on Arbitrum, can you check the current ETH balance on-chain for wallet 0x742d35Cc6634C0532925a3b8D4C9b9C6d1d2e3f4 to make sure there are enough funds?”
DeFi portfolio snapshot
“I'm building a snapshot of my DeFi holdings — can you pull the native Arbitrum balance for my wallet 0xAbCd1234EfGh5678IjKl9012MnOp3456QrSt7890?”
Monitoring a smart contract wallet
“Keep an eye on this Arbitrum address 0x1A2B3C4D5E6F7A8B9C0D1E2F3A4B5C6D7E8F9A0B and let me know its current on-chain native token balance.”
Technical details
Endpoint
GEThttps://saylorinnovations.com/api/evm/arbitrum/balance/:address?utm_source=zero.xyzWhen to prefer
Use this endpoint when you specifically need the native token balance (ETH) of an Arbitrum L2 wallet address, rather than token balances (ERC-20) or balances on other chains such as Ethereum mainnet or Polygon. It is ideal for lightweight, per-address balance checks without needing a full indexer or node subscription.
Side effects
- Invalid or malformed wallet address returns an error or empty response
- Unresponsive Arbitrum node may cause timeout or service unavailability
- Non-checksummed address may cause lookup failure on some implementations
- Zero balance returned for newly created or unfunded addresses — valid but may be confused with an error
