Where do I find a Solana transaction signature?

Transaction signatures appear in wallet apps after sending, on Solscan and Solana Explorer when browsing addresses. They are 87-88 character Base58 strings.

Can this decode failed transactions?

Yes. Failed transactions are still recorded on-chain. The decoder will show the error reason from the program logs.

Does this work for all Solana programs?

It parses raw instruction data for any program. For known programs like SPL Token, instructions are decoded into readable formats. Unknown programs show raw account list and data.

Frequently Asked Questions

Q: How do I decode a failed Solana transaction?

A: Paste the transaction signature and click Decode. Failed transactions show a red "Failed" status along with program logs that usually contain the on-chain error reason.

Q: Do I need a wallet connected to use this?

A: No. This tool only reads public on-chain data via the Solana RPC — it never asks for a wallet connection or private key.

Q: Is my transaction history saved anywhere online?

A: No. Saved transactions are stored only in your browser's local storage, never sent to a server.

Q: What network does this decoder use?

A: It queries Solana mainnet-beta by default via the public RPC endpoint.
