Transaction Info

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

Instructions

Step 1: Fetch Transaction Data

Run two complementary calls in parallel:

1. 1. getTransactionById — Type, raw data, sender/receiver, contract parameters, signatures, timestamp, expiration
2. INLINECODE1 — Result (SUCCESS/FAILED/REVERT), block number/timestamp, fee, energy/bandwidth usage, contract return value, internal txs, event logs

Step 2: Check Confirmation Status

1. 1. getBlock (no params) — Get current block height
2. Compare transaction's block number with latest block
3. INLINECODE3 — 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

Contract Type	Description	Key Fields
TransferContract	TRX transfer	from, to, amount
TransferAssetContract

TRC-10 transfer | from, to, asset, amount | | TriggerSmartContract | Contract call | contract, data (method + params) | | FreezeBalanceV2Contract | Stake 2.0 freeze | owner, amount, resource | | UnfreezeBalanceV2Contract | Stake 2.0 unfreeze | owner, amount, resource | | DelegateResourceContract | Resource delegation | from, to, resource, amount | | VoteWitnessContract | SR voting | owner, votes list | | CreateSmartContract | Contract deployment | owner, bytecode, ABI |

Step 4: Decode Smart Contract Calls

For TriggerSmartContract:

1. 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)

1. 3. If ABI available (via getContract), fully decode method name, parameters, and return value
2. 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

CODEBLOCK0

Error Handling

Error	Cause	Resolution
Transaction not found	Invalid hash, too old, or not yet broadcast	Verify hash format (64 hex chars); check pending pool with INLINECODE14
No receipt data

Transaction still pending | Note "Transaction pending, receipt not yet available" | | Cannot decode method | No ABI available for contract | Show raw data hex, identify common method signatures manually | | REVERT without reason | Contract reverted without error message | Check energy limit, parameter validity, and contract state |
