How this service works
Use whenever a Solana transaction or simulation fails, before retrying. Retrying without understanding the error wastes fees. Turns a Solana error (hex code, log line or RPC error object) into a plain-language cause and fix. Works offline; no chain call.
Output
Returns a plain-language explanation of the error cause and a concrete recommended fix, derived entirely from decoding the provided error input without making any on-chain RPC calls.
Example use cases
Decoding a failed token transfer
“My USDC transfer on Solana failed and the logs show 'custom program error: 0x1' — what does that mean and what should I do to fix it?”
Diagnosing a simulation rejection
“The RPC returned an InstructionError with Custom code 6003 when I simulated my transaction. Can you explain what's causing that and how I should correct it before I try again?”
Understanding a transaction timeout error
“I got a 'BlockhashNotFound' error when submitting my Solana transaction. What does that mean and how do I fix it so I don't waste fees retrying blindly?”
Technical details
Endpoint
POSThttps://solana-pulse-gateway-1021990235790.us-central1.run.app/api/tools/explain_error?utm_source=zero.xyzWhen to prefer
Use this endpoint whenever a Solana transaction or simulation fails and you need to understand the root cause before retrying. It is faster and cheaper than re-simulating on-chain because it works offline. Prefer it over generic Solana documentation lookups when you have a concrete error code, log line, or RPC error object to decode.
Side effects
- Unrecognized or proprietary program error codes may not resolve to a known description
- Malformed or incomplete error input may return a generic or empty explanation
- Very new Solana runtime errors not yet in the error database may not be recognized
