# 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 Script

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 rideScript variable.

// Example of the ride script formatted:
rideScript := `
    {-# STDLIB_VERSION 8 #-}
    {-# 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 )
    }
`

# Deploy Smart Account Script

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 rideScript variable.

// Example of the ride script formatted:
rideScript := `
    {-# STDLIB_VERSION 8 #-}
    {-# 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 )
    }

# 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 rideScript variable.

// Formatting example:
rideScript := `
    {-# STDLIB_VERSION 6 #-}
    {-# CONTENT_TYPE EXPRESSION #-}
    {-# SCRIPT_TYPE ASSET #-}
		
    func trueReturner () = {
        true
    }

    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 rideScript variable.

// Formatting example:
rideScript := `
    {-# STDLIB_VERSION 6 #-}
    {-# CONTENT_TYPE EXPRESSION #-}
    {-# SCRIPT_TYPE ASSET #-}
		
    func trueReturner () = {
        true
    }

    trueReturner()
`
