Solana mainnet SDK

How to integrate AllDomains Protocol:

libraries are opensource with MIT licenses: Typescript: https://github.com/onsol-labs/tld-parser Rust: https://github.com/onsol-labs/tld-parse-rs

1. Installation

npm install @onsol/tldparser

2. Domain Resolution

The following code shows how to get the Public Key owner of a domain name

• works with any AllDomains TLD

import { TldParser } from "@onsol/tldparser";
import { Connection } from "@solana/web3.js";

const RPC_URL = 'https://api.mainnet-beta.solana.com';

// initialize a Solana Connection
const connection = new Connection(RPC_URL);

// get the owner pubkey of a domain name
async function resolveDomain(domain){

    // initialize a Tld Parser
    const parser = new TldParser(connection);
    
    return await parser.getOwnerFromDomainTld(domain);
}

//get the owner pubkey of "miester.solana";
resolveDomain("miester.solana");

//get the owner pubkey of "miester.bonk"
resolveDomain("miester.bonk");

//get the owner pubkey of "miester.poor"
resolveDomain("miester.poor");

3. Get domains owned by a Public Key

a. Get all owned domains

import { TldParser, NameRecordHeader } from "@onsol/tldparser";
import { Connection, PublicKey } from "@solana/web3.js";

const RPC_URL = 'https://api.mainnet-beta.solana.com';

// initialize a Solana Connection
const connection = new Connection(RPC_URL);

// get all the domains owned by a public key
async function getOwnedDomains(owner: PublicKey){

    // initialize a Tld Parser
    const parser = new TldParser(connection);

    // get all owned domains
    let allUserDomains = await parser.getParsedAllUserDomains(owner);

    return allUserDomains;
}

// get all owned domains
getOwnedDomains(new PublicKey(""));

b. Get only unwrapped owned domains

import { TldParser, NameRecordHeader } from "@onsol/tldparser";
import { Connection, PublicKey } from "@solana/web3.js";

const RPC_URL = 'https://api.mainnet-beta.solana.com';

// initialize a Solana Connection
const connection = new Connection(RPC_URL);

// get only the unwrapped domains owned by a public key
async function getOwnedUnwrappedDomains(owner: PublicKey){

    // initialize a Tld Parser
    const parser = new TldParser(connection);
    
    // get only unwrapped domains
    let unwrappedUserDomains = await parser.getParsedAllUserDomainsUnwrapped(owner);

    return unwrappedUserDomains;
}

// get only unwrapped owned domains
getOwnedUnwrappedDomains(new PublicKey(""));

4. Get domains owned by a Public Key from a specific TLD

a. Get all owned domains from a specific TLD

import { TldParser, NameRecordHeader } from "@onsol/tldparser";
import { Connection, PublicKey } from "@solana/web3.js";

const RPC_URL = 'https://api.mainnet-beta.solana.com';

// initialize a Solana Connection
const connection = new Connection(RPC_URL);

// get the all the domains owned by a public key in a TLD
async function getOwnedDomainsFromTld(owner, tld){

    // initialize a Tld Parser
    const parser = new TldParser(connection);
    
    // get all owned domains from a TLD
    let ownedDomainsFromTld = parser.getParsedAllUserDomainsFromTld(owner, tld);

    return ownedDomainsFromTld;
}

//get all owned domains in the ".solana" Tld, without the "."
getOwnedDomainsFromTld(new PublicKey(""), "solana");

//get all owned domains in the ".bonk" Tld, without the "."
getOwnedDomainsFromTld(new PublicKey(""), "bonk");

//get all owned domains in the ".poor" Tld, without the "."
getOwnedDomainsFromTld(new PublicKey(""), "poor");

b. Get all only unwrapped owned domains from a specific TLD

import { TldParser, NameRecordHeader } from "@onsol/tldparser";
import { Connection, PublicKey } from "@solana/web3.js";

const RPC_URL = 'https://api.mainnet-beta.solana.com';

// initialize a Solana Connection
const connection = new Connection(RPC_URL);

// get only the unwrapped domains owned by a public key from a TLD
async function getOwnedUnwrappedDomainsFromTld(owner, tld){

    // initialize a Tld Parser
    const parser = new TldParser(connection);
    
    // get only unwrapped domains from a TLD
    let ownedUnwrappedDomainsFromTld = parser.getParsedAllUserDomainsFromTldUnwrapped(owner, tld);

    return ownedUnwrappedDomainsFromTld;
}

// get owned unwraped domains in the ".solana" Tld, without the "."
getOwnedUnwrappedDomainsFromTld(new PublicKey(""), "solana");

// get owned unwraped domains in the ".bonk" Tld
getOwnedUnwrappedDomainsFromTld(new PublicKey(""), "bonk");

// get owned unwraped domains in the ".poor" Tld
getOwnedUnwrappedDomainsFromTld(new PublicKey(""), "poor");

5. Get all active AllDomains TLDs

import { getAllTld } from "@onsol/tldparser";
import { Connection } from "@solana/web3.js";

const RPC_URL = 'https://api.mainnet-beta.solana.com';

// initialize a Solana Connection
const connection = new Connection(RPC_URL);

// get all active AllDomains TLDs
const allTlds = await getAllTld(connection);

6. Get all domains registered in All TLDs

import { NameRecordHeader, TldParser, findAllDomainsForTld, getAllTld } from "@onsol/tldparser";
import { Connection } from "@solana/web3.js";

const RPC_URL = 'https://api.mainnet-beta.solana.com';

// initialize a Solana Connection
const connection = new Connection(RPC_URL);

// slow
// please use no. 8 for a batch/faster implementation 
// this code doesn't check if a domain is expired or not
async function getAllRegisteredDomains(connection: Connection){
    //get all TLDs
    const allTlds = await getAllTld(connection);
    const parser = new TldParser(connection);
    let domains = [];
    for (let tld of allTlds) {

        //get the parent name record for a TLD
        const parentNameRecord = await NameRecordHeader.fromAccountAddress(connection, tld.parentAccount);
            
        //get all name accounts in a specific TLD
        const allNameAccountsForTld = await findAllDomainsForTld(connection, tld.parentAccount);

        if (!parentNameRecord || !parentNameRecord.owner) return;
        
        //parse all name accounts in a specific TLD
        for (let nameAccount of allNameAccountsForTld) {

            //get domain as string without the tld
            const domain = await parser.reverseLookupNameAccount(nameAccount, parentNameRecord.owner);
            domains.push(                {
                nameAccount: nameAccount,
                domain: `${domain}${tld.tld}`
            });
        }
    }
    return domains;
}

// get all domains registered on AllDomains
console.log(await getAllRegisteredDomains(connection))

1. Get User Main Domain

import { MainDomain, findMainDomain } from "@onsol/tldparser";
import { Connection, PublicKey } from "@solana/web3.js";


// returns MainDomain struct if it is available. it will return undefined if it is not.
// MainDomains are usually shown as mainDomain.domain + mainDomain.tld 
// the mainDomain.nameAccount is proof that the user has set it.
const fetchMainDomain = async (connection: Connection, pubkey: string | PublicKey): Promise<MainDomain | undefined> => {
    if (typeof pubkey === "string") {
        pubkey = new PublicKey(pubkey)
    }
    const [mainDomainPubkey] = findMainDomain(pubkey);
    let mainDomain = undefined;
    try {
        mainDomain = await MainDomain.fromAccountAddress(
            connection,
            mainDomainPubkey,
        );
        return mainDomain
    } catch (e) {
        console.log("No main domain found")
    }
    return mainDomain
};


const CONNECTION = new Connection("");
console.log(await fetchMainDomain(CONNECTION, "2EGGxj2qbNAJNgLCPKca8sxZYetyTjnoRspTPjzN2D67"))

// MainDomain {
//     nameAccount: PublicKey [PublicKey(9YzfCEHb62bQ47snUyjkxhC9Eb6y7CSodK3m8CKWstjV)] {
//       _bn: <BN: 7f0fb1f72ae0af9c5e7f5e4190d02ed2a720e88fb5787425157b9a9ec3fc39ec>
//     },
//     tld: '.solana',
//     domain: 'miester'
//   }
