delegatecall runs in the context of the caller contract.

Solidity: Multicall - Aggregate Multiple Contract Calls

Posted on 2023-10-282023-10-28Author VintaPosted in Blockchain

The main idea of Multicaller is to aggregate multiple contract function calls into a single one. It's usually to batch contract reads from off-chain apps. However, it could also be used to batch contract writes.

Solidity: Read Contract Storage by Slots with Foundry

Posted on 2023-08-032023-10-28Author VintaPosted in Blockchain

State variables are stored in different "slots" in a contract, and each slot is 32 bytes (256 bits). However, multiple adjacent state variables declared in the contract may be packed into the same slot by the Solidity compiler if their combined size does not exceed 32 bytes.
