Is Fuel Wallet safe?

Fuel Wallet is the official cryptocurrency wallet for the Fuel blockchain network with MEDIUM risk status. While the extension is legitimate and performs as advertised, several concerning issues were identified: (1) Mock Service Worker (MSW) testing library included in production build, (2) postMessage handlers without origin validation in development/test code, (3) CSP allows wasm-unsafe-eval, and (4) clipboard permission with seed phrase copy functionality. The extension does not exhibit malicious behavior, but the presence of development/testing artifacts in a production crypto wallet represents poor security hygiene.
