Registration

Registration instructions can be created either via SDK or API, both methods are equivalent. To register a domain you will have to specify the following:

• Domain names
• Space (between 1kb and 10kb)
• The public key of the buyer

SDK

Unregistered domains can be registered using the SDK @bonfida/spl-name-service with the following instructions:

import { registerDomainName } from "@bonfida/spl-name-service";

const name = "bonfida"; // We want to register bonfida.sol
const space = 1 * 1_000; // We want a 1kB sized domain (max 10kB)

const buyer = new PublicKey("..."); // Publickey of the buyer
const buyerTokenAccount = new PublicKey("..."); // Publickey of the token account of the buyer (USDC)

const [, ix] = await registerDomainName(name, space, buyer, buyerTokenAccount);

// sign and send the instruction

API

Registration instructions can also be created via API (equivalent to using the SDK):

POST https://naming-api.bonfida.com/registrar/new-domain

With the following request body

{
  "domain": "domain_to_register",
  "pubkey": "pubkey_of_the_user",
  "space": "domain_space", // Between 1_000 and 10_000
  "language": "0"
}
