# Transaction Replacement Attacks ⎊ Area ⎊ Resource 1 --- ## What is the Mechanism of Transaction Replacement Attacks? A transaction replacement attack occurs when a malicious actor replaces a pending, unconfirmed transaction in a cryptocurrency network with a new transaction that has the same nonce but a higher fee or different parameters. This is often executed by monitoring the mempool for pending transactions, then quickly broadcasting a replacement with a higher fee to incentivize miners to include the attacker's transaction instead. The original transaction is then effectively dropped. It exploits the Replace-By-Fee (RBF) feature. ## What is the Motivation of Transaction Replacement Attacks? The motivation for transaction replacement attacks is typically to achieve a double-spend, front-run an order, or disrupt a legitimate transaction. For instance, an attacker might send a low-fee transaction to a merchant, then replace it with a high-fee transaction sending the same funds back to themselves, effectively receiving goods without payment. In decentralized finance, this could involve front-running an arbitrage opportunity or manipulating oracle updates. These attacks aim to gain an unfair advantage. ## What is the Countermeasure of Transaction Replacement Attacks? Countermeasures against transaction replacement attacks involve waiting for multiple confirmations before considering a transaction final, particularly for high-value transfers. Merchants and platforms can disable RBF for incoming transactions or implement strict mempool monitoring to detect and reject suspicious replacements. For options trading, decentralized exchanges can employ batching mechanisms or specific ordering rules to mitigate front-running attempts. Education on transaction finality and network dynamics is also crucial for users. --- ## [Flash Loan Attacks](https://term.greeks.live/definition/flash-loan-attacks/) Exploiting uncollateralized, same-block loans to manipulate protocols and extract funds via price or logic vulnerabilities. ⎊ Definition ##
