Spelling Error in License
Description
The SPDX license identifier should be spelled correctly to ensure proper license recognition by development tools, blockchain explorers, and automated license compliance systems.
The license identifier contains a spelling error ("Lincense" instead of "License") that prevents proper license identification and could cause issues with automated tools and compliance systems.
Risk
Likelihood: High
-
License scanning tools will not recognize the incorrect identifier format
-
Automated license compliance tools may flag the contract as having unclear licensing
-
Code quality checkers and linting tools will report the misspelling as an error
Impact: Low
-
Legal uncertainty about contract licensing terms for users and integrators
-
Compliance issues in automated license scanning and organizational policies
-
Reduced professionalism in code presentation and documentation
-
Potential confusion about intended licensing terms and usage permissions
Proof of Concept
contract LicenseRecognitionTest {
function showAffectedTools() external pure returns (
string[] memory tools
) {
tools = new string[](8);
tools[0] = "GitHub license detection system";
tools[1] = "npm license-checker and similar tools";
tools[2] = "SPDX license compliance scanners";
tools[3] = "IDE extensions for license validation";
tools[4] = "Blockchain explorer source code viewers";
tools[5] = "Automated dependency license auditing";
tools[6] = "Corporate compliance scanning tools";
tools[7] = "Open source license management systems";
return tools;
}
function simulateRecognitionFailure() external pure returns (
string memory currentHeader,
string memory toolResult,
string memory correctHeader,
string memory fixedResult
) {
currentHeader = "// SPDX-Lincense-Identifier: MIT";
toolResult = "License: UNKNOWN or UNRECOGNIZED";
correctHeader = "// SPDX-License-Identifier: MIT";
fixedResult = "License: MIT (Massachusetts Institute of Technology)";
return (currentHeader, toolResult, correctHeader, fixedResult);
}
function showComplianceImplications() external pure returns (
string memory implication1,
string memory implication2,
string memory implication3
) {
implication1 = "Corporate policy scanners may flag as non-compliant";
implication2 = "Open source audits may require manual license verification";
implication3 = "Integration partners may be uncertain about usage rights";
return (implication1, implication2, implication3);
}
}
Real-world tool behavior:
GitHub displays "No license" despite MIT being intended
npm audit tools flag as "License: UNKNOWN"
Corporate compliance scans require manual review
IDE extensions show license warnings
Documentation generators can't identify license terms
Automated legal compliance becomes more complex
Recommended Mitigation
The mitigation fixes the spelling error to ensure proper license recognition by all automated tools and systems while maintaining the intended MIT license terms.
