Registering a Subdomain ​

Once you have registered a domain, you may want to create subdomains under it. This could be useful for organizing different sections or categories of your project or business. Here's a guide on how to register a subdomain:

Create a Subdomain ​

To create a subdomain, you need to call the createSubdomain method in the domain/subdomain contract where:

• name - this is the name of the subdomain you want to create.
• owner - this is the owner of the new subdomain.
• renewable - this is a flag that marks whether the owner of the subdomain can renew it at any time.

const domainContract = new provider.Contract(DOMAIN_ABI, domainAddress);

const createSubdomainTransaction = await domainContract.methods
  .createSubdomain({
    name: "sub.yourdomain.ever",
    owner: yourAddress,
    renewable: true,
  })
  .send({ from: yourAddress, amount: String(1e9), bounce: true });

Mapping a Subdomain to an Address ​

Once you have registered a subdomain, you can associate it with a blockchain address. This makes it easier for others to interact with that address, since they can use your easy-to-remember subdomain name instead of a complex blockchain address.

To do this, you simply need to call the setTarget method on your subdomain contract, passing the target address as the parameter. Here is how you can do it:

const subdomainContract = new provider.Contract(SUBDOMAIN_ABI, subdomainAddress);

const setTargetTransaction = await subdomainContract.methods
  .setTarget({ target: yourAddress })
  .send({ from: yourAddress, amount: String(1e9), bounce: true });
