Dynamic: can't resolve 'crypto'

If you're using Solana, you may encounter an error like this:

Module not found: Can't resolve 'crypto'

This is because you need to polyfill the crypto module.

If you're using webpack for example, your webpack config should look something like this:

const webpack = require('webpack');
module.exports = {
 resolve: {
   fallback: {
     "crypto": require.resolve("crypto-browserify"),
     "stream": require.resolve("stream-browserify"),
     "buffer": require.resolve("buffer/")
   }
 },
 plugins: [
   new webpack.ProvidePlugin({
     Buffer: ['buffer', 'Buffer'],
   }),
 ]
};
