By the end of 2025, let's take stock of those Web3 builders who have truly achieved results with the support of privacy computing tools.

These three projects are worth paying attention to—they are not just talking on paper but are actively verifying the value of privacy protection on-chain.

TradeVault focuses on private trading strategies. Traders fear their orders being exposed, but TradeVault uses privacy technology to leave verifiable proof of each strategy execution, protecting privacy while demonstrating that the transaction truly occurred. This is very attractive to high-frequency traders and institutions.

RomePay is pursuing on-chain payments. Payment scenarios are inherently privacy-sensitive. They have brought this requirement onto the chain, making the payment process both transparent and auditable, without exposing the identities and transaction details of the parties involved. They are walking a pretty steady line between compliance and privacy.

ExecSwap concentrates on confidential trading logic for DEXs. Traditional AMMs have a problem: your swap intent can be seen by anyone in the liquidity pool. ExecSwap uses privacy computing to encapsulate the exchange logic, preventing front-running bots from interfering.

All three directions point to the same core issue—Web3 needs to find a balance between transparency and privacy. Their explorations are worth learning from.
