💡 TL;DR: On-chain rules offer a robust defense against replay attacks, ensuring your crypto assets remain safe and secure.
Understanding Replay Attacks 🕵️♂️
Replay attacks in the crypto world are akin to someone eavesdropping on your conversation and then using your own words against you. In this context, it's when an attacker intercepts and fraudulently retransmits a transaction.
Real-World Example: The Notorious DAO Attack
In 2016, the DAO (Decentralized Autonomous Organization) experienced a replay attack, leading to the loss of 3.6 million ETH. The attacker exploited a flaw in the contract, illustrating the devastating potential of such attacks.
The Power of On-Chain Rules 🔒
On-chain rules act as a sentinel for your crypto transactions. Here’s how they work to prevent replay attacks:
- Unique Transaction Signatures: Each transaction is tied to a unique signature, invalidating any duplicate transaction attempts.
- Time Stamps: Transactions are time-stamped, ensuring they cannot be replayed at a later date.
- Programmable Restrictions: Specific conditions can be set, such as limiting the transaction amount or designating approved recipients only.

Why ZeroSig’s Approach is Game-Changing 🚀
At ZeroSig, we utilize OTP-based 2FA, adding an extra layer of security. Here’s why it matters:
- Dynamic Codes: Unlike static passwords, OTPs change with each transaction attempt, making them impervious to replay attacks.
