The growth momentum of the Ethereum ecosystem has been very strong in recent years, but there's one persistent issue—privacy. Whether it's transfers or transactions, on-chain information is almost entirely transparent, anyone can see it. Ordinary users feel unsafe, and institutions are even more dismissive.

This shortcoming has never been truly addressed. Previous privacy solutions tried either immature technology, poor user experience, or compliance issues. Some projects require users to install dedicated clients, making operations ridiculously complicated. Others can encrypt transactions but can't allow regulators to audit, and once compliance is involved, they hit a wall.

The recently emerging Hedger engine is different. It directly supports Ethereum's standard toolchain, so users can operate with their usual wallets, and developers can build with familiar tools—no extra hassle. The key is that its compliance design is very comprehensive—protecting privacy while not conflicting with regulators.

From a technical perspective, Hedger doesn't follow a single approach but combines homomorphic encryption and zero-knowledge proofs. Homomorphic encryption allows data to be computed directly in encrypted form without decryption, naturally eliminating the risk of leakage during intermediate steps. Zero-knowledge proofs are responsible for verifying that calculations are correct, ensuring no one can cheat. This combination solves privacy issues while guaranteeing security, making it more reliable than projects that rely solely on zero-knowledge proofs.

There's also a detail—support for hybrid UTXO and account models. This means it can be compatible with Ethereum's account system and enable cross-layer asset interactions. This is especially important for the EVM ecosystem.

In terms of practical applications, there are real implementations. Fuzzy order books can meet institutional trading privacy needs, no longer fearing order leakage. Confidential asset transfer functions protect ordinary users' assets, so balances are no longer exposed during transfers. Fast browser proofs can improve user experience, reducing waiting times.

These features are not just for technology's sake but are truly aimed at addressing real pain points in the EVM ecosystem. Institutions wanting to participate but worried about order leaks? Fuzzy order books solve that. Ordinary users wanting to transfer assets but afraid of revealing balances? Confidential asset transfer is the answer. It seems that privacy issues in the EVM ecosystem now have a more practical solution.
