### <a name="GAS-1"></a>[GAS-1] Use `selfbalance()` instead of `address(this).balance`
Use assembly when getting a contract's balance of ETH.
You can use `selfbalance()` instead of `address(this).balance` when getting your contract's balance of ETH to save gas.
Additionally, you can use `balance(address)` instead of `address.balance()` when getting an external contract's balance of ETH.

### <a name="GAS-3"></a>[GAS-3] `array[index] += amount` is cheaper than `array[index] = array[index] + amount` (or related variants)
When updating a value in an array with arithmetic, using `array[index] += amount` is cheaper than `array[index] = array[index] + amount`.
This is because you avoid an additonal `mload` when the array is stored in memory, and an `sload` when the array is stored in storage.
This can be applied for any arithmetic operation including `+=`, `-=`,`/=`,`*=`,`^=`,`&=`, `%=`, `<<=`,`>>=`, and `>>>=`.
This optimization can be particularly significant if the pattern occurs during a loop.
*Saves 28 gas for a storage array, 38 for a memory array*
*Instances (2)*:
```solidity
File: src/universal/StandardBridge.sol
286: deposits[_localToken][_remoteToken] = deposits[_localToken][_remoteToken] - _amount;
355: deposits[_localToken][_remoteToken] = deposits[_localToken][_remoteToken] + _amount;
```
### <a name="GAS-4"></a>[GAS-4] Using bools for storage incurs overhead
Use uint256(1) and uint256(2) for true/false to avoid a Gwarmaccess (100 gas), and to avoid Gsset (20000 gas) when changing from ‘false’ to ‘true’, after having been ‘true’ in the past.

### <a name="GAS-5"></a>[GAS-5] Cache array length outside of loop
If not cached, the solidity compiler will always read the length of the array during each iteration. That is, if it is a storage array, this is an extra sload operation (100 additional extra gas for each iteration except for the first) and if it is a memory array, this is an extra mload operation (3 additional gas for each iteration except for the first).

### <a name="GAS-6"></a>[GAS-6] State variables should be cached in stack variables rather than re-reading them from storage
The instances below point to the second+ access of a state variable within a function. Caching of a state variable replaces each Gwarmaccess (100 gas) with a much cheaper stack read. Other less obvious fixes/optimizations include having local memory caches of state variable structs, or having local caches of state variable contracts/addresses.
*Saves 100 gas per instance*

```
### <a name="GAS-7"></a>[GAS-7] Use calldata instead of memory for function arguments that do not get mutated
Mark data types as `calldata` instead of `memory` where possible. This makes it so that the data is not automatically loaded into memory. If the data passed into the function does not need to be changed (like updating values in an array), it can be passed in as `calldata`. The one exception to this is if the argument must later be passed into another function that takes an argument that specifies `memory` storage.

### <a name="GAS-9"></a>[GAS-9] Use Custom Errors
[Source](https://blog.soliditylang.org/2021/04/21/custom-errors/)
Instead of using error strings, to reduce deployment and runtime cost, you should use Custom Errors. This would save both deployment and runtime cost.

### <a name="GAS-12"></a>[GAS-12] 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.

### <a name="GAS-14"></a>[GAS-14] Using `private` rather than `public` for constants, saves gas
If needed, the values can be read from the verified contract source code, or if there are multiple values there can be a single getter function that [returns a tuple](https://github.com/code-423n4/2022-08-frax/blob/90f55a9ce4e25bceed3a74290b854341d8de6afa/src/contracts/FraxlendPair.sol#L156-L178) of the values of all currently-public constants. Saves **3406-3606 gas** in deployment gas due to the compiler not having to create non-payable getter functions for deployment calldata, not having to store the bytes of the value outside of where it's used, and not adding another entry to the method ID table

### <a name="NC-5"></a>[NC-5] Event is missing `indexed` fields
Index event fields make the field more quickly accessible to off-chain tools that parse events. However, note that each index field costs extra gas during emission, so it's not necessarily best to index the maximum allowed per event (three fields). Each event should use three indexed fields if there are three or more fields, and gas usage is not particularly of concern for the events in question. If there are fewer than three fields, all of the fields should be indexed.

### <a name="L-1"></a>[L-1] `abi.encodePacked()` should not be used with dynamic types when passing the result to a hash function such as `keccak256()`
Use `abi.encode()` instead which will pad items to 32 bytes, which will [prevent hash collisions](https://docs.soliditylang.org/en/v0.8.13/abi-spec.html#non-standard-packed-mode) (e.g. `abi.encodePacked(0x123,0x456)` => `0x123456` => `abi.encodePacked(0x1,0x23456)`, but `abi.encode(0x123,0x456)` => `0x0...1230...456`). "Unless there is a compelling reason, `abi.encode` should be preferred". If there is only one argument to `abi.encodePacked()` it can often be cast to `bytes()` or `bytes32()` [instead](https://ethereum.stackexchange.com/questions/30912/how-to-compare-strings-in-solidity#answer-82739).
If all arguments are strings and or bytes, `bytes.concat()` should be used instead

### <a name="L-2"></a>[L-2] Use of `tx.origin` is unsafe in almost every context
According to [Vitalik Buterin](https://ethereum.stackexchange.com/questions/196/how-do-i-make-my-dapp-serenity-proof), contracts should _not_ `assume that tx.origin will continue to be usable or meaningful`. An example of this is [EIP-3074](https://eips.ethereum.org/EIPS/eip-3074#allowing-txorigin-as-signer-1) which explicitly mentions the intention to change its semantics when it's used with new op codes. There have also been calls to [remove](https://github.com/ethereum/solidity/issues/683) `tx.origin`, and there are [security issues](solidity.readthedocs.io/en/v0.4.24/security-considerations.html#tx-origin) associated with using it for authorization. For these reasons, it's best to completely avoid the feature.
