Paste any Ethereum transaction hash. EVMHero traces the execution, decodes the function calls, and identifies exactly where things went wrong—or right.
See gas costs broken down to the wei. Understand which contract reverted and why. Get the error message decoded from hex into words you actually understand.
Then our AI explains it all in plain English: what the transaction attempted to do, and how to fix it if it didn’t complete as expected.
// Transaction 0x7f9a...3b21
{
"status": "success",
"from": "0x742d...4E2f",
"to": "Uniswap V3 Router",
"value": "0 ETH",
"gasUsed": "142,891",
"aiInsight": "Swapped 1,000 USDC
for 0.5 ETH via Uniswap..."
}
"This transaction swapped 1,000 USDC for 0.5 ETH on Uniswap V3. The swap executed at market rate with minimal slippage."
Whether you're debugging a failed deployment or just curious what a whale transaction actually did.
Faster Debugging
For Smart Contract Developers
Stop grep-ing through logs. See the exact function that reverted, the error message decoded, and AI-suggested fixes. Debug in seconds, not hours.
More Clarity
For DeFi Users & Traders
Finally understand what your swap, stake, or bridge actually did. No Solidity knowledge required—just paste the hash and read the plain-English summary.
Code Required
For Curious Explorers
Etherscan shows hex and "Success/Failed." EVMHero shows you the story: who sent what to whom, which contracts were called, and what it all means.
