Contract Analysis

Perform deep analysis of TRON smart contracts — deployment details, method signatures, call patterns, top callers, energy economics, and safety risk assessment.

MCP Server

• Prerequisite: TronGrid MCP Guide

Instructions

Step 1: Fetch Contract Basics

Run in parallel:

1. getContractInfo — Contract name, deployer (origin_address), consume_user_resource_percent, origin_energy_limit, creation time, energy usage stats
2. getContract — Full ABI definition, bytecode, whether ABI is available (indicates open-source status)

Step 2: Parse Contract Methods

From the ABI, categorize all methods:

• Read-only (view/pure): Safe calls, no state changes
• State-changing: transfers, approvals, settings
• Admin/Owner: privileged ops (mint, pause, blacklist, upgrade)
• Events: what the contract logs

Identify standard interfaces: TRC-20, TRC-721, TRC-1155, proxy/upgradeable patterns.

Step 3: Analyze Transaction Activity

1. getContractTransactions — Total count, recent patterns, success/failure rate
2. getEventsByContractAddress — Most frequent events, parameter patterns
3. getContractInternalTransactions — Inter-contract calls, TRX transfers within execution

Step 4: Identify Top Callers

From transaction data, aggregate:

• Top 5 by transaction count
• Top 5 by value (TRX or token amount)
• Classify callers: exchange, bot, regular user, other contract

Step 5: Estimate Energy Costs

Call estimateEnergy with common method calls to assess:

• Typical energy cost per transaction type
• Whether the contract is energy-efficient
• Cost split between user and contract owner (based on consume_user_resource_percent)

Step 6: Safety Assessment

High Risk indicators:

• No ABI (unverified/closed source)
• Unlimited mint capability
• Pause/freeze can lock user funds
• Blacklist function, self-destruct, hidden transfer fees
• Proxy pattern (upgradeable logic)
• consume_user_resource_percent = 100 (users pay all energy)

Medium Risk indicators:

• Very few unique callers vs. high tx count
• Recently created with sudden high activity
• Admin functions without timelock/multisig

Positive indicators:

• Open-source verified, standard implementation
• Timelock on admin functions, multisig requirements
• Long history with consistent activity, diverse callers

Step 7: Compile Contract Report

Error Handling

Error	Cause	Resolution
No ABI found	Contract not verified or ABI cleared	Note as unverified; analyze bytecode patterns and transaction data instead
Address is not a contract	Regular account address provided	Inform user this is a regular account, suggest using trongrid-account-profiling skill
No transactions	Newly deployed or unused contract	Report as inactive; check deployer's other contracts for context
Contract self-destructed	Contract no longer exists on-chain	Inform user; historical tx data may still be available

Examples

• Analyze USDT contract
• Check contract safety
