# Contracts Contract is the central concept in Solidity. It allows us to write reusable code (similarly as functions or classes in other languages) that can hold its state (variables) between transactions. There are two types of contracts: *contracts* (which can inherit from other contracts) and *libraries* (which cannot). ## Contract syntax The following code defines contract `Foo`: solidity
pragma solidity ^0.5.0; contract Foo {
} Contracts have visibility specifiers (`public`, `external`, `internal`, `private`) similar to functions. ## Contract inheritance Contracts can inherit from other contracts using `is` keyword: solidity
pragma solidity ^0.5.0; contract Base {
} contract Derived is Base {
} Contracts can inherit from multiple contracts: solidity
pragma solidity ^0.5.0; contract Base1 {
} contract Base2 {
} contract Derived is Base1, Base2 {
} ### Linearization Multiple inheritance means that when calling methods they can be called from several contracts. For example: solidity
pragma solidity ^0.5.0; contract Base1 {
function foo() public pure returns (uint256) {
return address(this).balance;
}
} contract Base2 {
function foo() public pure returns (uint256) {
return super.foo();
}
} contract Derived is Base1, Base2 {
} In this example `Derived.foo()` will return `Derived` balance. When calling `foo()` it will first call `Base1.foo()`, then because there is no such function in `Base1` it will search for it in next base contract (`Base2`) which has function `foo()` that calls `super.foo()`. Because `super` keyword resolves call order based on linearization order this will result in calling `Base1.foo()` again. If there was another base contract after `Base1` then it would call its function instead. Linearization order follows [C3 linearization algorithm](https://en.wikipedia.org/wiki/C3_linearization). This means that order of inheritance matters: solidity
pragma solidity ^0.5.0; contract Base1 {
function foo() public pure returns (uint256) {
return address(this).balance;
}
} contract Base2 {
function foo() public pure returns (uint256) {
return super.foo();
}
} contract Derived is Base1, Base2 {
} contract DerivedReversed is Base2, Base1 {
} In this case calling `DerivedReversed.foo()` will return balance of `Base1` because linearization order will be `[DerivedReversed,Base1,Base2]`. ## Contract storage layout Storage layout describes how variables are stored inside contract storage. It's important because: - variables have fixed storage locations;
- variables are accessed by index;
- storage locations are reused across different types;
- storage layout affects how contract inheritance works. ### Variable ordering Variables inside contract are stored by order they were declared: solidity
pragma solidity ^0.5.0; contract Foo { uint256 x;
uint256 y; function getXY() public view returns (uint256[2]) memory {
return [x,y];
} function setXY(uint256 _x,uint256 _y) public {
x = _x;
y = _y;
}
} In this example if we call `getXY()` after setting `(x,y)` as `(10u256**10u256**10u256**10u256**10u256**10u256**10u256**10u256**10u256**10u256**10u256**10u256**10u256**10u256**10u256**10u256**10,u256**20)` it will return `[x:100000000000000000000000000000000000000000000000000,y:100000000000000000000]`. This happens because: - first variable (`x`) takes up first storage slot;
- second variable (`y`) takes up second storage slot;
- both variables are stored as unsigned integers;
- both variables use only one slot because they are less than or equal to `uint(256)` size;
- both variables are stored at their respective positions within their slots (`x` at position `0`, `y` at position `0`);
- reading from storage slot only takes values at position `0`. ### Array ordering Arrays follow same ordering as normal variables: solidity
pragma solidity ^0.5.0; contract Foo { uint[3] x;
uint y; function getXY() public view returns (uint[3],uint) memory {
return [x,y];
} function setXY(uint[3] _x,uint _y) public {
x = _x;
y = _y;
}
} In this example if we call `getXY()` after setting `(x,y)` as `(10000,u256(20))` it will return `[10000,u256(20)]`. This happens because: - first variable (`x`) takes up first storage slot;
- second variable (`y`) takes up second storage slot;
- first variable (`x`) uses only one slot because its size fits into one slot (`3*8=24b <=32b`);
- first variable (`x`) uses positions within its slot as `[0...23]`;
- second variable (`y`) uses only one slot because its size fits into one slot (`8b <=32b`);
- second variable (`y`) uses position within its slot as `[0...7]`;
- reading from storage slot only takes values at positions `[0...7]`. ### Struct ordering Structs follow same ordering as normal variables: solidity
pragma solidity ^0.5.0; struct MyStruct { uint x;
uint y; } contract Foo { MyStruct x;
uint y; function getXY() public view returns (MyStruct,uint) memory {
return [x,y];
} function setXY(MyStruct _x,uint _y) public {
x = _x;
y = _y;
}
} In this example if we call `getXY()` after setting `(x,y)` as `{10000,u256(20)},20` it will return `{10000,u256(20)},20`. This happens because: - first variable (`x`) takes up first storage slot;
- second variable (`y`) takes up second storage slot;
- first variable (`x`) uses only one slot because its size fits into one slot (`16b <=32b`);
- first variable (`x`) uses positions within its slot as `[0...15]`;
- second variable (`y`) uses only one slot because its size fits into one slot (`8b <=32b`);
- second variable (`y`) uses position within its slot as `[0...7]`;
- reading from storage slot only takes values at positions `[0...7]`. ### Mappings ordering Mappings don't take up any space themselves but take space when written into them: solidity
pragma solidity ^0.5.0; contract Foo { mapping(address => uint) balances;
uint totalSupply; function getTotalsupply() public view returns (uint) memory {
return totalSupply;
} function getTotalBalance(address user) public view returns (uint) memory {
return balances[user];
} function setTotalsupply(uint supply) public {
totalSupply = supply;
} function setTotalBalance(address user,uint amount) public {
balances[user] = amount;
totalSupply += amount;
} } In this example if we call `getTotalBalance()` after setting `(totalSupply,balances[])` as `(10000,u200)` it will return `200`. This happens because: - first variable (`totalSupply`) takes up first storage slot;
- second variable doesn't take up any space itself but when written into it takes up another slot;
- reading from mapping reads value stored at location calculated by hashing key with key itself appended at end. ## Contract cloning Cloning allows creating new instances of existing contracts without having them deployed separately. solidity
pragma solidity ^0.5.0; import "@openzeppelin/contracts/cloneable/Cloneable.sol"; contract Foo is Cloneable { constructor () payable {} // payable constructor needed for cloning } In order for contract cloning to work constructor needs to be marked as *payable*. To clone contract use function from OpenZeppelin library: solidity
Foo foo = new Foo{value: msg.value}.createClone(); ## Libraries Libraries are similar to contracts but they don't hold any state themselves so they cannot be deployed separately. Libraries are intended for sharing reusable code between contracts. Library code must not contain stateful operations like sending ether or modifying state variables directly. Libraries do not support inheritance nor multiple inheritance. ## Libraries vs Contracts Libraries should be used when code does not need access to state variables or external data sources like block information or accounts balance. For example consider following library: solidity
library SafeMath { function add(uint x,uint y) internal pure returns (uint z){
z = x + y;
if((z > x) == false){
revert();
} return z; } } We can use this library with contract like so: solidity
pragma solidity ^0.5.0; import "./SafeMath.sol"; contract Test { using SafeMath for uint; // import library functions uint x; constructor () payable { x = msg.value.add(1); } } In this example library functions can be imported using statement like so: solidity
using SafeMath for uint; // import library functions Afterwards all functions become available under type they were imported for e.g.: solidity
msg.value.add(1); // calls SafeMath.add(msg.value,1) If library function does not fit well under some type it's possible use it directly like so: solidity
SafeMath.add(x,y); <|repo_name|>dmitrykudravtsev/solidity-tutorial<|file_sep|>/chapters/introduction.md
# Introduction Solidity is programming language designed for writing smart contracts that run on Ethereum Virtual Machine (EVM). Smart contracts are programs that run exactly as programmed without any possibility of downtime censorship manipulation or fraud provided network nodes are running correctly. Smart contracts can be used for many purposes like decentralized autonomous organizations decentralized marketplaces multi-signature wallets prediction markets asset tokenization etc. Ethereum network executes smart contracts using virtual machine called Ethereum Virtual Machine EVM which provides low level operations similar assembly language capable of manipulating arbitrary data structures while maintaining deterministic execution across all nodes. EVM also provides account abstraction allowing developers create accounts with arbitrary logic instead of just storing private keys balances etc. This tutorial will cover basics of Solidity language syntax types control structures errors events etc followed by more advanced topics such as security considerations gas optimization patterns libraries inheritance etc.<|file_sep|># Events Events allow logging data inside blockchain which cannot be read back but can be listened externally using web3.js or ethers.js libraries. Events are emitted using special keyword emit followed by event name arguments etc inside curly braces e.g.: solidity
event Log(address indexed user,uint value); function logData(address user,uint value){ emit Log(user,value); } <|file_sep|># Basic Types Solidity supports various basic types including integers booleans strings arrays mappings structs enums etc which form building blocks for writing smart contracts on Ethereum blockchain. ## Integers Integers come in two flavors signed integers signed integers ranging from -2147483648 (-231 )to2147483647 (+231 -1 )and unsigned integers unsigned integers ranging from zerozerozerozero zerozerozerozero zerozerozerozero zero zero zero zero zero zero zero zero zero zero zero zero zerozerozerozerozerozerozerozerozerozerozerozerozerozeroto4294967295 (+232 -1 )as shown below: soliDITY type int8 signed integer range -128 (-28 )to127 (+27 -1 ) type int16 signed integer range -32768 (-216 )to32767 (+215 -1 ) type int24 signed integer range -8388608 (-228 )to8388607 (+227 -1 ) type int32 signed integer range -2147483648 (-231 )to2147483647 (+231 -1 ) type int40 signed integer range -1099511627776 (-240 )to1099511627775 (+239 -1 ) type int48 signed integer range -281474976710
