Transaction Info

Query and intelligently decode TRON transactions — result status, confirmation, resource consumption, decoded method calls, internal transactions, event logs, and failure diagnosis.

MCP Server

• Prerequisite: TronGrid MCP Guide

Instructions

Step 1: Fetch Transaction Data

Run two complementary calls in parallel:

1. getTransactionById — Type, raw data, sender/receiver, contract parameters, signatures, timestamp, expiration
2. getTransactionInfoById — Result (SUCCESS/FAILED/REVERT), block number/timestamp, fee, energy/bandwidth usage, contract return value, internal txs, event logs

Step 2: Check Confirmation Status

1. getBlock (no params) — Get current block height
2. Compare transaction's block number with latest block
3. solidityGetTransactionById — Check if confirmed by solidity node (irreversible)

Classification:

• Confirmed (Irreversible): Found on solidity node
• Confirmed (Not yet irreversible): In recent block, not solidified
• Pending: Use getTransactionFromPending if needed
• Not Found: Invalid hash or expired

Step 3: Decode Transaction Type

Step 4: Decode Smart Contract Calls

For TriggerSmartContract:

1. Extract method signature (first 4 bytes of data)
2. Common signatures:
   • a9059cbb = transfer(address,uint256)
   • 095ea7b3 = approve(address,uint256)
   • 23b872dd = transferFrom(address,address,uint256)
3. If ABI available (via getContract), fully decode method name, parameters, and return value
4. Decode event logs for what actually happened

Step 5: Analyze Resource Consumption

From receipt, break down:

• Energy: Used amount, from staking vs. burned TRX
• Bandwidth: Used amount, free vs. staked
• Fee: Total TRX paid (divide by 1,000,000 for TRX)
• Energy Penalty: Over-usage penalty if applicable

Step 6: Internal Transactions

Call getInternalTransactionsByTxId for:

• TRX transfers between contracts
• Contract-to-contract calls
• Token distributions in complex transactions

Step 7: Parse Event Logs

Decode to human-readable descriptions:

• Transfer → "[amount] [token] from [A] to [B]"
• Approval → "[A] approved [B] to spend [amount]"
• Swap → "[A] swapped [X] tokenA for [Y] tokenB"

Step 8: Compile Transaction Report

## Transaction: [txid]

### Status
- Result: [SUCCESS / FAILED / REVERT]
- Confirmation: [Irreversible / Confirmed / Pending]
- Block: #[number] ([timestamp])

### Participants
- From: [address]
- To: [address / contract]
- Value: [amount] TRX / [token]

### Decoded Action
[Human-readable description]
e.g., "Transferred 1,000 USDT from TXxx... to TYyy..."
e.g., "Staked 10,000 TRX for Energy (Stake 2.0)"

### Resource Costs
- Energy: [amount] (staked: [X], burned: [Y])
- Bandwidth: [amount]
- Total Fee: [amount] TRX

### Internal Transactions
| From | To | Value | Note |
|------|----|-------|------|

### Events
[Decoded event logs]

### Failure Analysis (if failed)
- Revert Reason: [decoded]
- Likely Cause: [analysis]
- Suggestion: [actionable fix]
