# Set Up Smart Contracts

Deploy a smart contract after meeting the prerequisites.

# Prerequisites

Wallet: Set up a wallet via Keeper Wallet or WX Network.
NOTE: Ensure saving your wallet's seed phrase to send transactions.
Tokens: Obtain WAVES tokens to cover the transaction fee for each script deployment:
- For the Mainnet network: Get 0.001 WAVES via Available Market Options.
- For the Testnet network: Get 0.001 WAVES via Faucet.
- For the Stagenet network: Get 0.001 WAVES via Faucet.

# Tutorial

Follow the steps for the relevant smart contract type:

dApp.
Smart Account.
Smart Asset.

# Deploy dApp

Prepare your dApp script:

// Script example:
{-# STDLIB_VERSION 8 #-}
{-# CONTENT_TYPE DAPP #-}
{-# SCRIPT_TYPE ACCOUNT #-}

@Callable(i)
func checkStorageUntouchedByAlias(accountAlias: String) = {
    let alias = Alias(accountAlias)
    let res = if isDataStorageUntouched(alias) then {
        unit
    } else {
        throw("Data storage is not untouched by the alias")
    }
    ([], res)
}

Send a Set Script Transaction with:

Your seed phrase pasted into the seedPhrase variable.

Your dApp script pasted into the scriptSource variable.

// Example of the ride script formatted:
String scriptSource =
    "{-# STDLIB_VERSION 8 #-}\n" +
    "{-# CONTENT_TYPE DAPP #-}\n" +
    "{-# SCRIPT_TYPE ACCOUNT #-}\n\n" +
    "@Callable(i)\n" +
    "func checkStorageUntouchedByAlias(accountAlias: String) = {\n" +
    "    let alias = Alias(accountAlias)\n" +
    "    let res = if isDataStorageUntouched(alias) then {\n" +
    "        unit\n" +
    "    } else {\n" +
    "        throw(\"Data storage is not untouched by the alias\")\n" +
    "    }\n" +
    "    ([], res)\n" +
    "}";

# Deploy Smart Account

Prepare your smart asset script:

// Script example:
{-# STDLIB_VERSION 6 #-}
{-# CONTENT_TYPE EXPRESSION #-}
{-# SCRIPT_TYPE ACCOUNT #-}

let cooperPubKey = base58'BVqYXrapgJP9atQccdBPAgJPwHDKkh6A8'
let BTCId = base58'8LQW8f7P5d5PZM7GtZEBgaqRPGSzS3DfPuiXrURJ4AJS'
match tx {
    case o: Order =>
        sigVerify(o.bodyBytes, o.proofs[0], cooperPubKey ) && 
        (o.assetPair.priceAsset == BTCId || o.assetPair.amountAsset == BTCId)
    case _ => sigVerify(tx.bodyBytes, tx.proofs[0], cooperPubKey )
};

Send a Set Script Transaction with:

Your seed phrase pasted into the seedPhrase variable.

Your smart asset script pasted into the scriptSource variable.

// Example of the ride script formatted:
String scriptSource =
    "{-# STDLIB_VERSION 6 #-}\n" +
    "{-# CONTENT_TYPE EXPRESSION #-}\n" +
    "{-# SCRIPT_TYPE ACCOUNT #-}\n\n" +
    "let cooperPubKey = base58'BVqYXrapgJP9atQccdBPAgJPwHDKkh6A8'\n" +
    "let BTCId = base58'8LQW8f7P5d5PZM7GtZEBgaqRPGSzS3DfPuiXrURJ4AJS'\n" +
    "match tx {\n" +
    "    case o: Order =>\n" +
    "        sigVerify(o.bodyBytes, o.proofs[0], cooperPubKey ) && \n" +
    "        (o.assetPair.priceAsset == BTCId || o.assetPair.amountAsset == BTCId)\n" +
    "    case _ => sigVerify(tx.bodyBytes, tx.proofs[0], cooperPubKey )\n" +
    "};";

# Deploy Smart Asset Script

Prepare your smart asset script:

// Script example:
{-# STDLIB_VERSION 6 #-}
{-# CONTENT_TYPE EXPRESSION #-}
{-# SCRIPT_TYPE ASSET #-}

func trueReturner () = {
    true
}

trueReturner()

Follow the steps based on your goal:

To create a new smart asset with the defined script.
To add a smart asset script to an existing asset.

# Create Smart Asset

Send an Issue Transaction with:

Your seed phrase pasted into the seedPhrase variable.

Your smart asset script pasted into the scriptSource variable.

// Formatting example:
String scriptSource =
    "{-# STDLIB_VERSION 6 #-}\n" +
    "{-# CONTENT_TYPE EXPRESSION #-}\n" +
    "{-# SCRIPT_TYPE ASSET #-}\n\n" +
    "func trueReturner () = {\n" +
    "    true\n" +
    "}\n\n" +
    "trueReturner()";

# Add Asset Script

Send a Set Asset Script Transaction with:

Your seed phrase pasted into the seedPhrase variable.
Your asset ID pasted into the assetId variable.

Your smart asset script pasted into the scriptSource variable.

// Formatting example:
String scriptSource =
    "{-# STDLIB_VERSION 6 #-}\n" +
    "{-# CONTENT_TYPE EXPRESSION #-}\n" +
    "{-# SCRIPT_TYPE ASSET #-}\n\n" +
    "func trueReturner () = {\n" +
    "    true\n" +
    "}\n\n" +
    "trueReturner()";
