📚 Examples

🏦 Bonfida (Name Service)

Bonfida provides the Solana Name Service (SNS), enabling human-readable .sol domains and Twitter handle resolution.

🔍 Resolve Twitter Handle from Pubkey

import org.p2p.solanaj.core.PublicKey;
import com.mmorrell.bonfida.manager.NamingManager;
import org.p2p.solanaj.rpc.RpcClient;

RpcClient client = new RpcClient("https://api.mainnet-beta.solana.com");
NamingManager namingManager = new NamingManager(client);

PublicKey skynetPubkey = new PublicKey("GUfCR9mK6azb9vcpsxgXyj7XRPAKJd4KMHTTVvtncGgp");
String twitterHandle = namingManager.getTwitterHandle(skynetPubkey);

System.out.println("Twitter Handle: @" + twitterHandle);
// Output: Twitter Handle: @skynetcap

🔍 Resolve .sol Domain to Pubkey

PublicKey publicKey = namingManager.getPublicKeyBySolDomain("skynet");
System.out.println("skynet.sol = " + publicKey.toBase58());
// Output: skynet.sol = GUfCR9mK6azb9vcpsxgXyj7XRPAKJd4KMHTTVvtncGgp

🔍 Reverse Lookup: Pubkey to .sol Domain

PublicKey ownerPubkey = new PublicKey("GUfCR9mK6azb9vcpsxgXyj7XRPAKJd4KMHTTVvtncGgp");
Optional<String> domainName = namingManager.getDomainNameByPubkey(ownerPubkey);

domainName.ifPresent(domain -> {
    System.out.println("Domain: " + domain + ".sol");
});
// Output: Domain: skynet.sol

🔍 Batch Domain Resolution

List<String> domains = Arrays.asList("bonfida", "skynet", "solanafm");
Map<String, PublicKey> resolved = new HashMap<>();

for (String domain : domains) {
    try {
        PublicKey pubkey = namingManager.getPublicKeyBySolDomain(domain);
        resolved.put(domain, pubkey);
        System.out.println(domain + ".sol -> " + pubkey.toBase58());
    } catch (Exception e) {
        System.err.println("Failed to resolve: " + domain);
    }
}

🎨 Metaplex (NFT Metadata)

Metaplex provides the standard for NFT metadata on Solana.

🖼️ Get Token Metadata

import org.p2p.solanaj.core.PublicKey;
import com.mmorrell.metaplex.manager.MetaplexManager;
import com.mmorrell.metaplex.model.Metadata;

RpcClient client = new RpcClient("https://api.mainnet-beta.solana.com");
MetaplexManager metaplexManager = new MetaplexManager(client);

PublicKey tokenMint = new PublicKey("3uejHm24sWmniGA5m4j4S1DVuGqzYBR5DJpevND4mivq");
Optional<Metadata> metadata = metaplexManager.getTokenMetadata(tokenMint);

metadata.ifPresent(meta -> {
    System.out.println("Name: " + meta.getName());
    System.out.println("Symbol: " + meta.getSymbol());
    System.out.println("URI: " + meta.getUri());
    System.out.println("Creators: " + meta.getCreators());
});

🎯 Get Multiple Token Metadata

List<PublicKey> mints = Arrays.asList(
    new PublicKey("TokenMint1..."),
    new PublicKey("TokenMint2..."),
    new PublicKey("TokenMint3...")
);

Map<PublicKey, Metadata> metadataMap = new HashMap<>();

for (PublicKey mint : mints) {
    metaplexManager.getTokenMetadata(mint).ifPresent(meta -> {
        metadataMap.put(mint, meta);
        System.out.println(mint.toBase58() + ": " + meta.getSymbol());
    });
}

🔍 Check NFT Collection

PublicKey nftMint = new PublicKey("YourNFTMint...");
Optional<Metadata> metadata = metaplexManager.getTokenMetadata(nftMint);

metadata.ifPresent(meta -> {
    if (meta.getCollection() != null) {
        System.out.println("Collection: " + meta.getCollection().getKey().toBase58());
        System.out.println("Verified: " + meta.getCollection().isVerified());
    }
});

📖 OpenBook v2 (DEX)

OpenBook v2 is the community-driven successor to Serum, providing a fully on-chain central limit order book (CLOB).

📊 Get Real-time Orderbook

import com.mmorrell.openbook.manager.OpenBookManager;
import com.mmorrell.openbook.model.OpenBookMarket;
import org.p2p.solanaj.rpc.RpcClient;

RpcClient client = new RpcClient("https://api.mainnet-beta.solana.com");
OpenBookManager openBookManager = new OpenBookManager(client);

// SOL/USDC market
PublicKey marketId = PublicKey.valueOf("8BnEgHoWFysVcuFFX7QztDmzuH8r5ZFvyP3sYwn1XTh6");
Optional<OpenBookMarket> marketOpt = openBookManager.getMarket(marketId, false, true);

marketOpt.ifPresent(market -> {
    System.out.println("=== SOL/USDC Market ===");
    
    // Best bid/ask
    if (!market.getBidOrders().isEmpty()) {
        var bestBid = market.getBidOrders().get(0);
        System.out.println("Best Bid: $" + bestBid.getPrice() + " x " + bestBid.getSize());
    }
    
    if (!market.getAskOrders().isEmpty()) {
        var bestAsk = market.getAskOrders().get(0);
        System.out.println("Best Ask: $" + bestAsk.getPrice() + " x " + bestAsk.getSize());
    }
    
    // All bids
    System.out.println("\n📈 Bids:");
    market.getBidOrders().forEach(order -> {
        System.out.printf("  $%.2f x %.3f from %s\n", 
            order.getPrice(), 
            order.getSize(),
            order.getTrader().toBase58().substring(0, 8) + "...");
    });
    
    // All asks
    System.out.println("\n📉 Asks:");
    market.getAskOrders().forEach(order -> {
        System.out.printf("  $%.2f x %.3f from %s\n", 
            order.getPrice(), 
            order.getSize(),
            order.getTrader().toBase58().substring(0, 8) + "...");
    });
});

📋 Get All Available Markets

List<PublicKey> markets = openBookManager.getOpenBookMarkets();
System.out.println("Total OpenBook Markets: " + markets.size());

markets.forEach(marketPubkey -> {
    System.out.println("Market: " + marketPubkey.toBase58());
});

🎯 Monitor Event Heap

import com.mmorrell.openbook.model.OpenBookEventHeap;

PublicKey marketId = PublicKey.valueOf("8BnEgHoWFysVcuFFX7QztDmzuH8r5ZFvyP3sYwn1XTh6");
Optional<OpenBookEventHeap> eventHeap = openBookManager.getEventHeap(marketId);

eventHeap.ifPresent(heap -> {
    System.out.println("=== Market Events ===");
    heap.getOutEvents().forEach(event -> {
        System.out.println("Event: " + event.toString());
    });
    
    heap.getFillEvents().forEach(fill -> {
        System.out.printf("Fill: Maker=%s, Taker=%s, Price=%.2f, Size=%.4f\n",
            fill.getMaker().toBase58().substring(0, 8),
            fill.getTaker().toBase58().substring(0, 8),
            fill.getPrice(),
            fill.getQuantity()
        );
    });
});

⚙️ Crank Market Events

import org.p2p.solanaj.core.Account;

PublicKey marketId = PublicKey.valueOf("8BnEgHoWFysVcuFFX7QztDmzuH8r5ZFvyP3sYwn1XTh6");
Account crankerAccount = Account.fromJson(readKeyFile());

Optional<String> txId = openBookManager.consumeEvents(
    crankerAccount,
    marketId,
    10  // Max events to consume
);

txId.ifPresentOrElse(
    tx -> System.out.println("✅ Cranked events: " + tx),
    () -> System.out.println("ℹ️ No events to consume")
);

📊 Calculate Market Spread

Optional<OpenBookMarket> marketOpt = openBookManager.getMarket(marketId, false, true);

marketOpt.ifPresent(market -> {
    if (!market.getBidOrders().isEmpty() && !market.getAskOrders().isEmpty()) {
        double bestBid = market.getBidOrders().get(0).getPrice();
        double bestAsk = market.getAskOrders().get(0).getPrice();
        double spread = bestAsk - bestBid;
        double spreadBps = (spread / bestBid) * 10000;
