Implement Rate Limiting in wallets.js

[BrosG]

The file wallets.js doesn't seem to have any rate limiting or throttling mechanisms in place. This could leave the application vulnerable to brute-force attacks, especially when it comes to sensitive operations such as creating wallets and decrypting existing ones.
Suggestion: Implement rate limiting or throttling on sensitive endpoints to mitigate the risk of brute-force attacks. Express-rate-limit is a good library for rate limiting if you're using Express.js.
Code Example:
`const rateLimit = require("express-rate-limit");

const apiLimiter = rateLimit({
windowMs: 15 * 60 * 1000, // 15 minutes
max: 100
});

app.use("/api/", apiLimiter);
