How this service works
OATP · tx_explainer — Fetch a Solana transaction by signature and return a human-readable explanation: programs invoked, token balance changes, fee (SOL + USD), and a one-line summary.
Output
Returns a structured breakdown of the Solana transaction including: list of programs invoked, token balance changes per wallet, transaction fee in both SOL and USD, and a concise one-line human-readable summary of what the transaction accomplished.
Example use cases
Audit suspicious wallet transaction activity
“I just received a transaction from someone claiming they sent me tokens, but I'm skeptical. Can you break down what actually happened in this transaction — 3vZj8n2K5qL9m4pR7sT1u6vW8xY9zA0bC2dE3fG4hI5j? I need to see what programs touched my wallet, what tokens changed hands, and the total fee they paid.”
Explain DeFi swap costs to client
“My client is asking why that token swap on Solana cost so much. Can you give me a plain-English explanation of this transaction — 8mN4kP6jQ2rS8tU1vW3xY5zA7bC9dE0fG1hI2jK3lM4? Show me the fee in both SOL and USD, which programs were involved, and what actually got swapped.”
Verify token transfer completeness
“I need to confirm that all the tokens arrived correctly in this transaction. Can you translate this Solana tx hash into plain English and walk me through the balance changes — 2aB5cD8eF1gH4iJ7kL0mN3oP6qR9sT2uV5wX8yZ1aC4? Include the programs that were called and the final cost to the sender.”
Technical details
Endpoint
POSThttps://api.oatp.cc/tools/tx_explainerWhen to prefer
Use this endpoint when you need a plain-English explanation of a specific Solana transaction — especially when debugging DeFi interactions, auditing wallet activity, or presenting on-chain data to non-technical users. Prefer this over raw RPC calls when you need fee data in both SOL and USD and a summarized narrative rather than raw instruction logs.
Side effects
- Invalid or malformed transaction signature returns an error
- Transaction not found on-chain (wrong network or pruned) returns not-found error
- Network timeout if Solana RPC is slow or unavailable
- Payment failure if x402 payment of 0.5 USDC is not completed
