+###  [GAS-1] x += y costs more gas than x = x + y for state variables
+use = + or = - instead to save gas
+
+*Instances (3)*:
+```solidity
+File: src/Pair.sol
+
+448:             balanceOf[from] -= amount;
+
+453:             balanceOf[to] += amount;
+
+```

+
+```solidity
+File: src/lib/SafeERC20Namer.sol
+
+35:             charCount += uint8(b[i]);
+
+```
+[Link to code](https://github.com/code-423n4/2022-12-caviar/tree/main/src/lib/SafeERC20Namer.sol)
+
+###  [GAS-2] Splitting require() statements that use && saves gas
+Saves 16 gas per instance. If you’re using the Optimizer at 200, instead of using the && operator in a single require statement to check multiple conditions, multiple require statements with 1 condition per require statement should be used to save gas.
+
+*Instances (1)*:
+```solidity
+File: src/Pair.sol
+
+71:             require(baseTokenAmount > 0 && fractionalTokenAmount > 0, "Input token amount is zero");
+
+```
+[Link to code](https://github.com/code-423n4/2022-12-caviar/tree/main/src/Pair.sol)
+
+
+###  [GAS-3] Add Unchecked {} For Subtractions Where The Operands Cannot Underflow Because Of A Previous Require() Or If-statement
+The unchecked keyword can saves 30-40 gas per line.
+
+*Instances (1)*:
+```solidity
+File: src/Pair.sol
+
+168:             uint256 refundAmount = maxInputAmount - inputAmount;
+
+```
+[Link to code](https://github.com/code-423n4/2022-12-caviar/tree/main/src/Pair.sol)
+
+
+###  [GAS-4] Functions Guaranteed To Revert When Called By Normal Users Can Be Marked Payable
+If a function modifier such as onlyOwner is used, the function will revert if a normal user tries to pay the function. Marking the function as payable will lower the gas cost for legitimate callers because the compiler will not include checks for whether a payment was provided.
+
+*Instances (2)*:
+```solidity
+File: src/LpToken.sol
+
+19:             function mint(address to, uint256 amount) public onlyOwner {
+
+26:             function burn(address from, uint256 amount) public onlyOwner {
+
+```
