Solana Transaction Decoder.
Paste any transaction signature to see the full decoded breakdown — programs, instructions, token transfers, accounts, and logs. No signup required.
Paste any Solana mainnet transaction signature to see its full decoded breakdown — accounts, instructions, token transfers, programs, and logs.
What this tool decodes
Programs
Identifies every program invoked — Pump.fun, Jupiter, Raydium, Orca, Token Program, System Program, and more.
Instructions
Shows each instruction with its accounts, raw data, and all inner (CPI) instructions in the call tree.
Token transfers
Extracts all SPL token movements with mint labels, amounts, and direction (in/out) for each account.
Accounts
Lists every account involved with labels for known programs and tokens. Copy any address with one click.
Compute & fees
Shows compute units consumed, transaction fee in SOL, and transaction version (legacy vs v0).
Log messages
Full program log trace with syntax highlighting for invocations, errors, and success messages.
Need this data in real-time?
This tool decodes one transaction at a time. For trading bots and real-time applications, Subglow delivers pre-parsed JSON for every matching transaction via Yellowstone gRPC streaming — with zero client-side decoding and sub-5ms delivery.
Frequently asked questions
What does this tool do?
It fetches any Solana mainnet transaction by its signature, then decodes and displays the full breakdown — which programs were called, what instructions were executed, which tokens moved, account interactions, compute units, fees, and log messages. All in a human-readable format.
Is this free?
Yes, completely free with no signup required. Paste a transaction signature and decode it instantly.
Why do I need to decode transactions?
Solana transactions contain compiled instructions with raw byte data. Without decoding, you see base64-encoded blobs and account index numbers. This tool resolves program IDs to human-readable names (Pump.fun, Jupiter, Raydium, etc.), labels known token mints, and shows the actual data flow.
How is this different from Solscan or Solana Explorer?
This tool focuses on the raw instruction-level detail that bot developers need — inner instructions, instruction data hex, account roles, and the full log trace. It also labels DeFi-specific programs (Pump.fun, Raydium, Jupiter, Orca) that generic explorers don't always identify.
How does Subglow deliver this data faster?
This tool decodes one transaction at a time via RPC. Subglow's gRPC streaming service does this server-side for every matching transaction in real-time — delivering pre-parsed JSON with zero client-side decoding. The 15-30ms you spend parsing here is eliminated entirely.
