Introduction Yul is an intermediate language that can be used with Solidity or as a standalone language . It is particularly useful for writing optimized Smart Contract Lets look at some Coding Examples { // Declare variables without specifying t...
Alright Let’s Continue from where we left , Previous One : Demystifying Memory in EVM (Part I) Memory Initialization When a contract is executed , the EVM initializes a free memory pointer to 0×80. This is done to provide some space for stack operati...
Okay let’s first look at the code contract Demo { uint256 a = 0x1a01; // Slot 0 uint256 b = 0x2a01; // Slot 1 mapping(uint => uint) c; // Slot 2 uint256 d = 0x5a01; // Sot 3 constructor(){ c[10] = 0xfe3f; c[100] =...
When Storing Dynamic type data , We don’t explicitly store the data in the next immediate slot, instead we only store the address of the slot where the element of that index is , In simpler words we are basically storing the “Pointer” to the actual a...
Let’s first have a look at the Code contract Demo{ uint256 a 1234 // slot 0 uint8 b = 0x12; // slot 1 uint8[6] c = [1,2,3,4,5,6]; // line 4 (slot 2) uint256[2] d = [10,20] // line 5 slot(3 & 4) function getSlotvalue(uint slot) public...
