Quick start​

import com.ombrachain.sdk.*;
import java.math.BigInteger;
import java.util.List;

Wallet wallet = Wallet.fromMnemonic("...12 words...");
OmbraClient client = new OmbraClient("https://api.ombra-net.com");

var acct = client.getAccount(wallet.getAddress());
long nonce = acct.get("nonce").asLong();

// Transfer
var tx = TxBuilder.buildTransferTx(
    wallet.getAddress(), "0xrecipient...",
    BigInteger.valueOf(1_000_000),  // 1 OMBRA
    BigInteger.valueOf(1000),       // 0.001 OMBRA fee
    nonce, wallet.getPrivateKey()
);
client.submitTx(tx);

Fork V6 — Agentic AI​

String runId = TxBuilder.computeAgentRunId(wallet.getAddress(), nonce, "Explain Bitcoin");
String convId = TxBuilder.computeConversationId(wallet.getAddress(), null);

var agentTx = TxBuilder.buildAgentRequestTx(
    wallet.getAddress(), runId, convId,
    "Explain Bitcoin in 100 words",
    List.of("web_search", "chain_query"),
    BigInteger.valueOf(Constants.MICRO_OMBRA),  // 1 OMBRA escrow
    100, null, null,
    nonce, wallet.getPrivateKey()
);
client.submitTx(agentTx);

var status = client.getAgentRun(runId);
System.out.println("status: " + status.get("status").asText());

Cross-language compatibility​

Acest SDK produce semnături bit-exact cu @ombrachain/sdk (TS) și ombrachain (Python). Canonical JSON folosește LinkedHashMap pentru insertion order + Jackson BigInteger → string serializer.
