How this service works
EVM Nonce (arbitrum). Arbitrum account nonce: confirmed and pending transaction count for any address.
Output
Returns the current transaction nonce (integer) for the specified Ethereum address on the Arbitrum network, representing the number of transactions sent from that address and indicating the next valid nonce for a new transaction.
Example use cases
Pre-flight nonce check before sending transaction
“Before I broadcast my next transaction on Arbitrum, can you check the current nonce for 0x742d35Cc6634C0532925a3b8D4C9B2F5d1234567 so I know what value to use?”
Debugging stuck or pending transactions
“My Arbitrum transaction seems stuck — can you look up the on-chain nonce for 0xAbCdEf1234567890AbCdEf1234567890AbCdEf12 to see if there's a nonce gap causing the issue?”
Monitoring wallet activity level
“How many transactions has 0x1234567890abcdef1234567890abcdef12345678 sent on Arbitrum so far? I want to know their nonce to gauge how active this wallet is.”
Technical details
Endpoint
GEThttps://saylorinnovations.com/api/evm/arbitrum/nonce/:address?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, pay-per-call nonce lookup specifically on the Arbitrum Layer 2 network without setting up your own RPC node or managing API keys for a full blockchain provider. Ideal for agents automating Arbitrum transactions who need the current nonce on demand.
Side effects
- Invalid or malformed Ethereum address returns an error
- Network connectivity issues to Arbitrum RPC nodes may cause timeouts
- Address with no transactions returns nonce of 0 (valid but may be unexpected)
- Rate limiting or payment failure (x402) blocks the request
