Build quantum-safe dApps on RougeChain
Transfers · DEX · NFTs · Shielded Transactions · Bridge · Rollups · Mail · Messenger

The official SDK for RougeChain — a post-quantum Layer 1 blockchain secured by ML-DSA-65 (CRYSTALS-Dilithium). All transaction signing happens client-side with NIST-approved post-quantum cryptography. Private keys never leave your application.

Works in the browser, Node.js 18+, and React Native.

Install

Wallet & Addresses

import { Wallet, pubkeyToAddress, isRougeAddress, formatAddress } from "@rougechain/sdk";

// Generate a new post-quantum keypair
const wallet = Wallet.generate();

// Get the compact rouge1... address (~63 chars vs 3904-char hex pubkey)
const address = await wallet.address();
// "rouge1q8f3x7k2m4n9p..."

// Restore from saved keys
const restored = Wallet.fromKeys(publicKey, privateKey);

// Export for storage
const keys = wallet.toJSON(); // { publicKey, privateKey }

// Verify keypair integrity
wallet.verify(); // true

// Address utilities
const addr = await pubkeyToAddress(someHexPubKey);
const display = formatAddress(addr); // "rouge1q8f3x7...k9m2"
isRougeAddress("rouge1q8f3x7k2m4..."); // true

Transfers & Tokens

// Send XRGE
await rc.transfer(wallet, { to: recipient, amount: 100 });

// Send custom token
await rc.transfer(wallet, { to: recipient, amount: 50, token: "MYTOKEN" });

// Create a new token (costs 100 XRGE)
await rc.createToken(wallet, {
  name: "My Token",
  symbol: "MTK",
  totalSupply: 1_000_000,
  image: "https://example.com/logo.png", // optional — URL or data:image/webp;base64,...
});

// Update token metadata (creator only)
await rc.updateTokenMetadata(wallet, {
  symbol: "MTK",
  image: "data:image/webp;base64,UklGR...", // base64 logos persist on-chain
  description: "A community token",
  website: "https://mytoken.io",
});

// Burn tokens
await rc.burn(wallet, 500);

DEX (rc.dex)

// List all pools
const pools = await rc.dex.getPools();

// Get a single pool
const pool = await rc.dex.getPool("XRGE-MTK");

// Get price history (PriceSnapshot[]) — for building charts
const prices = await rc.dex.getPriceHistory("XRGE-MTK");
// Each snapshot: { pool_id, timestamp, block_height, reserve_a, reserve_b, price_a_in_b, price_b_in_a }

// Get pool stats (volume, trade count)
const stats = await rc.dex.getPoolStats("XRGE-MTK");

// Get pool events (swaps, adds, removes)
const events = await rc.dex.getPoolEvents("XRGE-MTK");

// Get a swap quote
const quote = await rc.dex.quote({
  poolId: "XRGE-MTK",
  tokenIn: "XRGE",
  tokenOut: "MTK",
  amountIn: 100,
});
console.log(`You'll receive ${quote.amount_out} MTK`);

// Execute swap with slippage protection
await rc.dex.swap(wallet, {
  tokenIn: "XRGE",
  tokenOut: "MTK",
  amountIn: 100,
  minAmountOut: quote.amount_out * 0.98, // 2% slippage
});

// Create a new liquidity pool
await rc.dex.createPool(wallet, {
  tokenA: "XRGE",
  tokenB: "MTK",
  amountA: 10_000,
  amountB: 5_000,
});

// Add / remove liquidity
await rc.dex.addLiquidity(wallet, {
  poolId: "XRGE-MTK",
  amountA: 1000,
  amountB: 500,
});
await rc.dex.removeLiquidity(wallet, { poolId: "XRGE-MTK", lpAmount: 100 });

NFTs (rc.nft)

RC-721 standard with collections, royalties, freezing, and batch minting.

// Create a collection (5% royalty, max 10k supply)
await rc.nft.createCollection(wallet, {
  symbol: "ART",
  name: "My Art Collection",
  royaltyBps: 500,
  maxSupply: 10_000,
});

// Mint
await rc.nft.mint(wallet, {
  collectionId: "abc123",
  name: "Piece #1",
  metadataUri: "https://example.com/nft/1.json",
  attributes: { rarity: "legendary" },
});

// Batch mint (up to 50 at once)
await rc.nft.batchMint(wallet, {
  collectionId: "abc123",
  names: ["#1", "#2", "#3"],
});

// Transfer with sale price (triggers royalty)
await rc.nft.transfer(wallet, {
  collectionId: "abc123",
  tokenId: 1,
  to: buyerPubKey,
  salePrice: 100,
});

// Query
const myNfts = await rc.nft.getByOwner(wallet.publicKey);

Bridge (rc.bridge)

Bridge assets between Base Sepolia and RougeChain L1. Supports ETH ↔ qETH, USDC ↔ qUSDC, and XRGE.

// Check bridge status & supported tokens
const config = await rc.bridge.getConfig();
// { enabled: true, supportedTokens: ["ETH", "USDC"], chainId: 84532 }

// Claim qETH after depositing ETH to custody address
await rc.bridge.claim({
  evmTxHash: "0x...",
  evmAddress: "0x...",
  evmSignature: "0x...",
  recipientPubkey: wallet.publicKey,
  token: "ETH",
});

// Claim qUSDC after depositing USDC
await rc.bridge.claim({
  evmTxHash: "0x...",
  evmAddress: "0x...",
  evmSignature: "0x...",
  recipientPubkey: wallet.publicKey,
  token: "USDC",
});

// Withdraw qETH → receive ETH on Base Sepolia
await rc.bridge.withdraw(wallet, {
  amount: 500_000,
  evmAddress: "0xYourAddress",
  tokenSymbol: "qETH",
});

// XRGE bridge
const xrgeConfig = await rc.bridge.getXrgeConfig();
await rc.bridge.withdrawXrge(wallet, {
  amount: 1000,
  evmAddress: "0xYourAddress",
});

Rollup (zk-STARK Batch Proofs)

Submit transfers to the rollup accumulator for batched STARK proving. Transfers are collected into batches of up to 32 and proven with a single zk-STARK proof.

// Check rollup status
const status = await rc.getRollupStatus();
// { pending_transfers, completed_batches, current_state_root, ... }

// Submit a transfer to the rollup batch
const result = await rc.submitRollupTransfer({
  sender: wallet.publicKey,
  receiver: recipientPubKey,
  amount: 100,
  fee: 1,
});
// result.queued = true (waiting for batch) or result.batch_completed = true

// Get a completed batch result
const batch = await rc.getRollupBatch(1);
// { batch_id, transfer_count, proof_size_bytes, proof_time_ms, verified, ... }

Mail (rc.mail)

On-chain encrypted email with @rouge.quant addresses.

// Send an encrypted email
await rc.mail.send({
  from: wallet.publicKey,
  to: recipientPubKey,
  subject: "Hello",
  body: "This is a test",
  encrypted_subject: encryptedSubject,
  encrypted_body: encryptedBody,
});

// Read inbox
const inbox = await rc.mail.getInbox(wallet.publicKey);

// Move to trash
await rc.mail.move(messageId, "trash");

// Mark as read
await rc.mail.markRead(messageId);

Messenger (rc.messenger)

End-to-end encrypted messaging with media and self-destruct support.

// Register wallet for messaging
await rc.messenger.registerWallet({
  id: wallet.publicKey,
  displayName: "Alice",
  signingPublicKey: wallet.publicKey,
  encryptionPublicKey: encPubKey,
});

// Create a conversation
const result = await rc.messenger.createConversation([
  wallet.publicKey,
  recipientPubKey,
]);

// Fetch conversations (with extended key matching)
const convos = await rc.messenger.getConversations(wallet.publicKey, {
  signingPublicKey: wallet.publicKey,
  encryptionPublicKey: encPubKey,
});

// Send an encrypted message (with optional self-destruct)
await rc.messenger.sendMessage(conversationId, wallet.publicKey, encryptedContent, {
  selfDestruct: true,
  destructAfterSeconds: 30,
});

// Read messages
const messages = await rc.messenger.getMessages(conversationId);

// Delete a message
await rc.messenger.deleteMessage(messageId);

Shielded Transactions (rc.shielded)

Private value transfers using zk-STARK proofs. Shield XRGE into private notes, transfer privately, and unshield back to public balance.

import { createShieldedNote, computeCommitment, computeNullifier } from "@rougechain/sdk";

// Shield 100 XRGE into a private note
const { note } = await rc.shielded.shield(wallet, { amount: 100 });
// ⚠️ Save `note` securely — losing it means losing the funds!
// note = { commitment, nullifier, value, randomness, ownerPubKey }

// Check pool stats
const stats = await rc.shielded.getStats();
// { commitment_count, nullifier_count, active_notes }

// Check if a nullifier has been spent
const { spent } = await rc.shielded.isNullifierSpent(note.nullifier);

// Private transfer (requires STARK proof from Rust prover)
await rc.shielded.transfer(wallet, {
  nullifiers: [note.nullifier],
  outputCommitments: [recipientCommitment],
  proof: starkProofHex,
});

// Unshield back to public balance
await rc.shielded.unshield(wallet, {
  nullifiers: [note.nullifier],
  amount: 100,
  proof: starkProofHex,
});

// Client-side crypto primitives
const randomness = generateRandomness();
const commitment = computeCommitment(100, wallet.publicKey, randomness);
const nullifier = computeNullifier(randomness, commitment);

Low-Level Signing

For advanced use cases:

import { signTransaction, verifyTransaction, generateNonce } from "@rougechain/sdk";

const payload = {
  type: "transfer" as const,
  from: wallet.publicKey,
  to: recipient,
  amount: 100,
  fee: 1,
  token: "XRGE",
  timestamp: Date.now(),
  nonce: generateNonce(),
};

const signedTx = signTransaction(payload, wallet.privateKey, wallet.publicKey);
const valid = verifyTransaction(signedTx); // true

Address Resolution

Resolve between compact rouge1… addresses and full hex public keys using the on-chain persistent index.

// rouge1… → public key
const { publicKey } = await rc.resolveAddress("rouge1q8f3x7k2m4...");

// public key → rouge1…
const { address } = await rc.resolveAddress(hexPubKey);

// Both return: { success, address, publicKey, balance }

Push Notifications

Register Expo push tokens for real-time notifications. Requires PQC signature — only the wallet owner can register.

// Register (wallet signs the request with ML-DSA-65)
await rc.registerPushToken(wallet, expoPushToken);

// Unregister
await rc.unregisterPushToken(wallet);

Nonce Management

// Get sequential nonce for an account
const { nonce, next_nonce } = await rc.getNonce(wallet.publicKey);
