Abstract

EIP-1283 significantly lowers the gas costs of writing to contract's storage. This created a danger of a new kind of reentrancy attacks on existing contracts as Solidity by default grants a 'stipend' of 2300 gas to simple transfer calls. This danger is easily mitigated if SSTORE is not allowed in low gasleft state, without breaking the backward compatibility and the original intention of this EIP.
