EVM Memory Explained: Layout, Expansion Gas, and Solidity Safety
Learn how EVM memory works, why expansion costs gas, how Solidity uses the free memory pointer, and which assembly mistakes can corrupt execution.

Learn how Solidity assigns Ethereum contract storage slots, how mappings and arrays derive locations, and how to inspect state safely with eth_getStorageAt.

Learn how Ethereum CREATE2 predicts a contract address from a factory, salt, and init code, with Solidity examples, use cases, and security checks.

Compare Solidity abi.encode and abi.encodePacked, see why packed dynamic values can collide, and choose safer encoding for hashes and contract calls.

Learn how Ethereum transient storage works, when EIP-1153 clears data, how Solidity exposes it, and which reentrancy and composability risks matter.
Learn how Ethereum event logs work, how indexed topics differ from data, how to query eth_getLogs, and what reorgs and decoding can break.
