How this service works
Decode one Base transaction into plain English: sender, receiver, ETH value, status, the known method behind the selector, every ERC-20 transfer it made, and a one-sentence summary. Use this when an agent needs to explain or verify what a transaction actually did before acting on it.
Output
Returns the decoded transaction details including sender address, receiver address, ETH value transferred, transaction status (success/fail), the human-readable method name behind the function selector, a list of every ERC-20 transfer event with token, amount, from, and to, and a concise one-sentence plain-English summary of what the transaction did.
Example use cases
Verify transaction before releasing funds
“Before I mark this payment as confirmed, decode Base transaction 0xabc123... and tell me if it succeeded, who the sender was, and how much USDC was transferred.”
Explain DeFi swap to a user
“My user just did a transaction on Base — hash 0xdef456... — can you decode it and give me a plain-English summary of what happened, including any token swaps or transfers?”
Audit suspicious wallet activity
“I see a transaction on Base with hash 0x789ghi... that looks unusual — decode it and tell me the sender, receiver, ETH value, the method that was called, and every ERC-20 transfer it triggered.”

Endpoint
POSThttps://stall-row-production.up.railway.app/v1/tx-decoder?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to explain, verify, or audit a specific Base network transaction in human-readable terms before taking action — especially when ERC-20 token flows or method identification matter. Prefer over a raw block explorer when a structured JSON response and plain-English summary are needed programmatically.
Side effects
- Invalid or malformed transaction hash returns an error
- Transaction hash not found on Base network (wrong chain or hash)
- Unrecognized function selector returns raw selector without method name
- Pending transactions may not yet be decodable
- Network or RPC timeouts on busy blocks
