How this service works
Robinhood Chain account nonce (latest + pending) for building transactions. Send { address }.
Output
Returns the current latest (confirmed) nonce and pending nonce for the specified Robinhood Chain address, giving the caller the exact sequence number needed to construct a valid next transaction without collision.
Example use cases
Pre-transaction nonce check
“Before I submit a transaction on Robinhood Chain, fetch the latest and pending nonce for wallet 0x1234567890abcdef1234567890abcdef12345678 so I know what sequence number to use.”
Preventing transaction replay or stuck tx
“I have a stuck pending transaction on Robinhood Chain for address 0xDeAdBeEf0000000000000000000000000000dEaD — can you pull the current pending nonce so I can figure out how to replace it?”
Multi-step agent transaction sequencing
“My agent is about to send three consecutive transactions from 0xaBcD1234000000000000000000000000000AbCd on Robinhood Chain — get the current nonce so I can correctly increment it across all three.”
Technical details
Endpoint
POSThttps://x402-services-production.up.railway.app/api/rhchain/nonceWhen to prefer
Use this endpoint when building or signing transactions specifically on Robinhood Chain (rhchain) and you need an accurate, up-to-date nonce that accounts for both confirmed and pending transactions. Prefer this over generic EVM nonce lookups when targeting rhchain specifically, as it is purpose-built for that network.
Side effects
- Invalid or malformed Ethereum address returns an error response
- Address not found on Robinhood Chain may return zero nonce or an error
- Network or RPC connectivity issues may cause timeouts
- Missing required 'address' field in request body returns a validation error
