+
+### [G-01] Value Not Pre-Calculated
+
+Readability can be sacrificed for user gas savings. The value `160 - 4 * 4` can be pre-calculated to `144` and inlined to save gas.
+
+#### Findings:

+Links: [55](https://github.com/code-423n4/2022-12-caviar/blob/main/src/lib/SafeERC20Namer.sol#L55).
+```solidity
+55:	return Strings.toHexString(uint160(token) >> (160 - 4 * 4));
+```
+**Suggested Change**
+```solidity
+55:	return Strings.toHexString(uint160(token) >> (144));
+```
+
+### [G-02] `uint256` Iterator Checked Each Iteration
+
+A `uint256` iterator will not overflow before the check variable overflows. Unchecking the iterator increment saves gas.
+**Example**
+```solidity
+//From
+for (uint256 i; i < len; ++i) {
+	//Do Something
+}
+//To
+for (uint256 i; i < len;) {
+	//Do Something
+	unchecked { ++i; }
+}
+```

+39:	for (uint256 i = 0; i < charCount; i++) {

+
+
+### [G-03] `x += y` Used
+
+`x = x + y` is cheaper than `x += y` in some cases like below.

+```
+**Suggested Change**
+```solidity
+35:	charCount = charCount + uint8(b[i]);
