Cryptocurrency wallet addresses are publicly available and transactions can be traced. In the instance that your name or other information is associated publicly with your wallet address, the transactions that you make on the blockchain can be traced back to you. A cryptocurrency stealth address is a single-use wallet address used to create more anonymity in cryptocurrency transactions ensuring that no one can trace payments back to you.
A stealth address acts as a proxy for your wallet address. When you use a stealth address, the blockchain records the transaction and enters the proxy address — hence hiding your public address. A stealth address can be created using different protocols or mechanisms within a cryptocurrency wallet as long as it supports it.
