📋 Common Transaction Types
Sending ETH/crypto from one address to another. Lowest gas cost (~21,000 gas on Ethereum).
Moving ERC-20 tokens. Higher gas than ETH transfers (~50,000+ gas) because it calls smart contract.
Exchanging tokens on DEX like Uniswap. Complex interactions = high gas (100,000-500,000+ gas).
Publishing new smart contract. Very expensive (500,000-5,000,000+ gas depending on code size).
🔍 Decoding Transaction Data
Hex-encoded function calls for smart contracts. Empty for simple transfers, contains method signature + parameters for contract interactions.
Transaction counter for the sender's address. Prevents replay attacks - each transaction must have sequential nonce.
Gas Limit = max you're willing to spend. Gas Used = actual amount consumed. Unused gas is refunded.
How much you pay per gas unit. Higher = faster confirmation. EIP-1559 uses base fee + priority fee model.
