How this service works
Decode a Solana transaction into structured instructions, program ids (named), accounts and a human summary. Accepts a base64 serialized transaction (offline) or a landed signature (RPC jsonParsed). Use before signing/sending, or to understand a landed tx.
Output
Returns a JSON object with an error field (null if successful), the source type (signature or raw), and a human-readable summary listing the number of instructions and the programs invoked (e.g. System Program, SPL Token). Additional decoded instruction details may be included.
Example use cases
Inspect suspicious wallet activity
“I got this Solana transaction signature — 4xYZ...mNqR on mainnet — can you decode it and tell me what programs and instructions were involved?”
Debug a failed DeFi transaction
“My Solana transaction failed and I need to understand what went wrong. Here's the signature: 3aBc...dEfG on devnet — can you decode it and show me the instructions that were attempted?”
Audit a raw unsigned transaction before signing
“Before I sign this base64-encoded Solana transaction, can you decode it and summarize what instructions it's going to execute on mainnet?”
Technical details
Endpoint
GEThttps://pay.ansht.tech/v1/decodeWhen to prefer
Choose this endpoint when you need a quick, paid-per-use decode of a Solana transaction by signature or raw bytes without setting up your own RPC infrastructure. It's ideal for AI agents that need on-demand, human-readable summaries of Solana instructions without managing Solana node connections or parsing binary transaction formats manually.
Side effects
- Invalid or malformed transaction signature returns an error in the 'err' field
- Unknown or unrecognized program IDs may result in incomplete instruction labeling
- Specifying the wrong cluster (mainnet vs devnet) for a given signature will cause lookup failure
- Malformed base64 body will result in a parse error
- Network or RPC node unavailability may cause timeout or upstream errors
