# FAQ

### Is it possible to create a multisig account?

Yes, multisig accounts are natively supported. Here is a simple example of how you can set up a multisig account:

```
# Add two accounts to your local keychain
gameid keys add ms1
gameid keys add ms2

# Create a multisig account requiring the above 2 accounts
gameid keys add ms1ms2 --multisig-threshold=2 --multisig=ms1,ms2

# Signing and broadcasting a TX
#1.) Define an unsigned-tx.json file with your unsigned transaction
# {"body":{"messages":[{"@type":"/cosmos.bank.v1beta1.MsgSend","from_address":"MULTI_SIG_ACCOUNT","to_address":"DESIRED_DESTINATION_ADDRESS","amount":[{"denom":"ugame","amount":"10"}]}],"memo":"","timeout_height":"0","extension_options":[],"non_critical_extension_options":[]},"auth_info":{"signer_infos":[],"fee":{"amount":[{"denom":"ugame","amount":"100000"}],"gas_limit":"200000","payer":"","granter":""}},"signatures":[]}

#2.) Sign unsigned tx from both signers (see unsigned-tx.json) and output json files of signed tx's
gameid tx sign unsigned-tx.json --multisig=multisigAccountName --from=ms1 --output-document=signer1_signedTx.json --node YOUR_RPC_URL
gameid tx sign unsigned-tx.json --multisig=multisigAccountName --from=ms2 --output-document=signer2_signedTx.json --node YOUR_RPC_URL

# 3.) Sign tx from multisig account and output to json file of signed tx
gameid tx multisign unsigned-tx.json ms1ms2 signer1_signedTx.json signer2_signedTx.json > signedTx.json

# 4.) Broadcast multisig tx
gameid tx broadcast signedTx.json
```

### Why did smart contract ran out of gas at 300,000?

For all the Gameluk provided public nodes, we have set a maximum gas of 300,000. If your contract requires more gas, you will need to set up your own node and rpc url.\
\
Additionally it is important that you run all your smart contracts through [rust-optimizer](https://github.com/CosmWasm/rust-optimizer) so that your gas is low and your contract is optimized.

### How can I create a wallet given a mnemonic seed phrase?

```
import { restoreWallet } from '@gameluk-js/core';

//Takes an optional account index
const wallet = await restoreWallet(YOUR_SEED_PHRASE, 2);

// Now your wallet can be used with other @game-js helper functions
const client = await getSigningCosmWasmClient(RPC_URL, wallet);
```

### Resolving "ReferenceError: process is not defined"

The "ReferenceError: process is not defined" error often occurs when developing web3 applications that rely on Node.js-specific libraries, such as `process` or `Buffer`. This error shows up because web browsers do not natively support these Node.js modules.

While the @game-js package internally handles these discrepancies by including the necessary polyfills, you might encounter this or similar errors due to other third-party libraries not bundling those dependencies. When this happens, you'll have to manually include the required polyfills in your project.\
\
If you are using Vite or rollup you can add the following to the entry point of your app.

```
import * as process from 'process';
import { Buffer } from 'buffer';

// Polyfill self for browser and global for Node.js
const globalObject = typeof self !== 'undefined' ? self : global;

Object.assign(globalObject, {
	process: process,
	Buffer: Buffer
});

```

If you are using Webpack you can use the following plugin in you Webpack config. 

If you are using Webpack you can use the following plugin in you Webpack config.

```
yarn add -D node-polyfill-webpack-plugin
```

```
import NodePolyfillPlugin from 'node-polyfill-webpack-plugin';

... // the rest of your webpack config
plugins: [
    ...
    new NodePolyfillPlugin(),
    ...
],
...
```
