What Alternative to Transfer Is Recommended for Sending Ether Securely in Modern Solidity?
The recommended alternative is to use the low-level call function combined with the Checks-Effects-Interactions pattern and an explicit gas limit of zero, or a very low, safe amount. A common secure pattern is (bool success, ) = recipient.call{value: amount, gas: 0}("");.
By limiting gas or ensuring state is updated first, the risk is mitigated without the fragility of the 2,300 stipend.
