Ethereum: Can I use an exclusive address for all transactions?

When it comes to transactions at Ethereum Blockchain, users are often asked about best practices to protect their assets and ensure the safety of their funds. A common question is whether it is possible to use a single public key (ADDR1) for all transactions or if each transaction requires at least two keys: the sender’s public key (ADDR1) and the receiver’s private key (Key2). In this article, we will explore the implications of the use of individual addresses for all transactions in Ethereum.

The risks of individual addresses

Individual addresses can be vulnerable to various attacks. Here are some reasons for:

* Restored vulnerabilities

: When a transaction is sent from the ADDR1 and then re -between the transaction loop (for example, with a script called), an invader can explore this vulnerability.

* Double Expenses Attacks

: If multiple transactions are sent to the same address and each transaction has a different script or data, an attacker may try a double base base by sending repeated transactions from the same direction.

* Reveal confidential information : Individual addresses can reveal confidential information about an individual’s identity history and transactions.

Use of various directions

To mitigate these risks, users often use multiple addresses for different purposes. Here are some scenarios where the use of various directions makes sense:

• Segregated Liquidity Protocols (SLP) : SLPs allow users to create decentralized exchange (DEX) that facilitate the exchange of assets without exposing confidential information about their identity.

• Layer 2 : Layer 2 solutions, such as optimism and polygon, provide faster and scalable transaction processing than Ethereum primary network. In such cases, using multiple addresses can help users avoid safety risks associated with individual addresses.

• Private Transactions : By sending private transactions, it is usually not possible to use only one address without exposing confidential information.

Best practices for safe transactions

To minimize the risks associated with individual addresses, here are some of the best practices:

• Use safe wallets : Invest in good reputation and audited wallets that offer advanced security resources such as two authentication factors, multipreña wallets and cold storage.

• Divide the funds into separate wallets : When dividing the funds into various wallets or addresses, make sure each wallet has its own safe storage solution, which includes cold storage and authentication of two factors.

• Use segregation addresses : Organize your assets in wallets or segregated addresses to minimize the risk of double expenses attacks.

• Enable Reenivation Protection : When you use scripts that call other intelligent contracts, allow entry protection to avoid reentry vulnerabilities.

Conclusion

Although it is theoretically possible to use a single direction for all transactions in Ethereum, it is not recommended, unless it is already part of a segregated liquidity protocol or layer 2. To protect your assets and ensure the safety of your funds, it is essential To use various directions for different purposes and follow the best practices for safe transactions processing. Always invest in good reputation portfolios, secrete your assets and allow reenification protection to minimize the risks associated with individual addresses.
