How this service works
Structured decode of any mainnet tx (base | ethereum | solana) — $0.001 USDC
Output
A structured breakdown of the transaction including chain, transaction type, from/to addresses, token or ETH value, decoded function name and typed parameters, and any relevant metadata such as block number and timestamp.
Example use cases
Audit a suspicious DeFi swap
“I've got this Base transaction hash 0x7f3a...c891 that someone flagged as suspicious — can you decode it and tell me exactly what function was called, what tokens were swapped, how much, and who was involved?”
Explain a Solana transaction plainly
“What actually happened in this Solana transaction 5xHt...K2mP? Break it down for me — who sent it, what did it do, and what values or tokens were moved?”
Extract calldata from Ethereum tx
“I have an Ethereum mainnet tx hash 0xd94b...11fa and I need to know what contract function was called and what the exact typed parameters were — can you decode the calldata and give me a structured breakdown?”
Technical details
Endpoint
POSThttps://1c09pdnrx1.execute-api.us-east-1.amazonaws.com/v1/decode/txWhen to prefer
Use this endpoint when you need a single unified decoder that handles Base, Ethereum, and Solana transactions without needing to route to chain-specific tools. Prefer it when you need structured, typed output from a raw transaction hash, especially for DeFi or cross-chain workflows where the chain may vary.
Side effects
- Invalid or malformed transaction hash returns 400 error
- Transaction not found on specified chain returns 404
- Unsupported chain specified returns 422 or error
- Unverified or unrecognized contract ABI means calldata may be partially decoded
- Payment failure via x402 protocol returns 402 Payment Required
