How this service works
Latest transaction signatures for an address (signature, slot, blockTime, error flag). ?limit= up to 1000. Live, for activity tracking.
Output
Returns a list of up to 1000 transaction signature records for the specified Solana address, each containing the transaction signature string, slot number, blockTime (Unix timestamp), and a boolean error flag indicating whether the transaction failed.
Example use cases
Audit wallet activity before payment
“Before I send funds to Solana address 9WzDXwBbmkg8ZTbNMqUxvQRAyrZzDsGYdLVL9zYtAWWM, pull up its last 100 transaction signatures so I can see how active it has been and whether any transactions failed.”
Monitor agent wallet for new transactions
“Keep an eye on Solana address 4fYNw3dojWmQ3dMDfb4G7z9HUQ9tZv8XWjgRMTMhWm4q — fetch the latest 200 transaction signatures and flag any that have error flags set.”
Investigate suspicious on-chain activity
“I think there's been unusual activity on Solana address 3h1zGmCwsRJnVk5Bu1ybqpJ4c7YCkBSk5N1xCEBq1Qx — can you get me the most recent 1000 transaction signatures with their slot numbers and block times?”
Technical details
Endpoint
GEThttps://47620.xyz/x/solana-fac/signatures/:solana_address?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a live, up-to-date list of recent transaction signatures for a Solana address for activity monitoring, auditing, or pre-payment due diligence. Prefer it over full transaction detail endpoints when you only need signatures, slots, block times, and error flags — it is faster and cheaper than fetching full transaction data.
Side effects
- Invalid Solana address format returns an error
- Limit parameter exceeding 1000 may be capped or rejected
- Address with no transaction history returns empty list
- Network or RPC unavailability causes timeout or 5xx error
- Malformed request returns 400 bad request
