Ethereum is not only a transfer network. It is also the home of smart contracts, decentralized applications, stablecoins, token launches, staking systems, and many forms of on-chain finance. That makes ETH tracking more layered than BTC-only analysis. An ETH wallet can interact with a wide mix of contracts and tokens, and each interaction may add context that matters to an exchange or investigator.
For example, a transfer may look clean if you view only the last movement. But once you look back through the path of value, you may see contract activity, bridge flows, or interactions with risky addresses that change how the wallet should be interpreted. That is why Ethereum tracking often requires both transaction review and contract-aware analysis.
