How this service works
Diagnose a failed Solana or Base transaction from on-chain evidence. Returns cause, supporting evidence and a proposed correction with explicit simulation limits.
Output
Returns the identified root cause of the transaction failure, the on-chain evidence supporting that diagnosis, a proposed correction to resolve the issue, and explicit simulation limits to validate the fix before resubmitting.
Example use cases
Debug reverted Base swap
“My Base transaction 0x9b1c3e5f7a2d4f6e8c0a2b4d6e8f0a2c4e6f8b0d2e4f6a8c0b2d4f6e8a0c2e4f just failed, probably during a swap — can you figure out exactly why it reverted and what I need to change to get it through?”
Diagnose failed Solana mint
“This Solana transaction signature 5KtP8mNqR3xJvLwY7bAcQfZp2sUhMkXdEiGnVoT1rWyB9jCeDzFuN4HaK6lSOPg didn't go through — can you look at the on-chain evidence and tell me the root cause and how to correct it?”
Investigate repeated Base transaction failures
“I keep getting failures on Base for this tx hash 0x1a2b3c4d5e6f7a8b9c0d1e2f3a4b5c6d7e8f9a0b1c2d3e4f5a6b7c8d9e0f1a2b — diagnose what's actually going wrong on-chain and suggest the fix with simulation bounds.”
Technical details
Endpoint
POSThttps://kair-os.trade/tx-diagnostic/diagnose?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured, evidence-backed root-cause analysis of a failed blockchain transaction on Base or Solana, particularly when you want a proposed correction alongside the diagnosis. Prefer this over generic block explorers when you need machine-readable output with explicit simulation limits for automated retry logic.
Side effects
- Invalid or malformed transaction hash format returns validation error
- Transaction not found on the specified chain returns not found error
- Chain mismatch between specified chain and actual transaction chain
- Transaction that succeeded rather than failed may return unexpected results
- Network congestion or RPC unavailability may delay or fail the lookup
