Using Vite you will stuck with issue. As workaround you may initialize provider like in the example below.

`js
import { Address, ProviderRpcClient } from 'everscale-inpage-provider';
import { EverscaleStandaloneClient } from 'everscale-standalone-client';

const client = new ProviderRpcClient({
forceUseFallback: true,
fallback: () =>
EverscaleStandaloneClient.create({
connection: {
/.../
},
initInput: '../../node_modules/nekoton-wasm/nekoton_wasm_bg.wasm',
}),
});
