Register payment token

For our marketplace, we need to register and mint a payment token, which will be used to buy and sell cards.

We first register an asset we will use as a payment token using the FT4 library, which has built-in operations for registering assets.

Let's create an asset with the following parameters:

• Name: Collector Card
• Symbol: CRD
• Decimals: 6
• URL to icon: https://url-to-asset-icon

This registration should occur immediately upon deploying our blockchain. To achieve this, we utilize an object that functions as a global singleton within our dapp. This object is initialized at the launch of the blockchain, ensuring the asset's registration is executed at startup.

src/rell_marketplace/module.rell

module;

import lib.ft4.assets.{ asset, Unsafe };

object dapp_meta {
    asset = Unsafe.register_asset("Collector Card", "CRD", 6, chain_context.blockchain_rid, "https://url-to-asset-icon");
}

Now we can use dapp_meta.asset from within the dapp to access the asset when doing transfers.
