You can’t have privacy, unless it is at the protocol level by default. ZEC would be an example of the problem of optional privacy.

These are 3 private wallets that I have known.
https://ywallet.app/ - Wallet for ZCash, a blockchain with encrypted “shielded” transactions and wallets
https://www.railway.xyz/ - Privacy-focused based on Ethereum chain
https://samouraiwallet.com/ - Secured transactions on Bitcoin Wallet

well Tornado Cash of course.

Yes its still very much alive, i think the current mirror is tornado3.cash

Railgun and their railway wallet, they let you use Ethereum privately without any traces in scanners.

Best I can think of is Railgun. They’re live and fully on chain with no bridges and a private wallet. Can do some basic shielded DeFi stuff too as well as private transfers so you can send funds completely privately

Zama Surprised nobody mentioned it.

The most advanced FHE on solidity yet with their fhEVM lib

0x0.ai

It is a privacy dex a.i. token. They also have tools to see if a project is a scam or a high possibility of a rug pool. The fees associated with The Exchange goes back to the holders holding Oxo tokens the holders get rewarded in Native eth.

I’m glad to see you’re interested about on-chain privacy. Secret is providing PAAS for Ethereum to unlock the Next Generation of EVM DApps with Confidential Smart Contracts Ethereum.

It is also providing access to powerful Private DeFi for ETH via MetaMask Wallet that allows you Take out private loans, Swap without value extraction, Share details if needed, and Protect yourself from hackers & scammers.
