Dara — Privacy Toolkit for Solana

Dara is a mainnet Solana privacy toolkit that breaks the on-chain link between your wallet and your trades. Swap tokens anonymously via a server-side relayer, launch tokens with distributed stealth pre-buys, and let AI warn you before you swap into a rug-pull.

Live Mainnet Proof

All features have been tested and verified on Solana Mainnet.

Action	Details	Proof
Token Launch	DRX — FDdocTzx55am...doge	View on Solscan ↗
Anonymous Swap	SOL → USDC	View on Solscan ↗
Pre-Buy	Stealth wallet created	View on Solscan ↗

Key proof: Check the swap transaction — the signer is the relayer (61jfZuYGSY9RCmRXQnCqjuHmeudXVv1USQm89NoGF5ee), NOT the user's wallet. No on-chain link.

How It Works

User Wallet (Phantom/Solflare)
    |
    | 1. Deposits SOL to relayer
    v
Next.js API Routes (relayer logic)
    |
    |-- Anoncoin API (token creation)
    |-- Jupiter API (swap execution)
    |-- OpenAI API (risk analysis)
    v
Relayer Wallet (server-side keypair)
    |
    | 2. Executes Jupiter swap (user wallet NOT in tx)
    | 3. Transfers tokens to stealth wallet ATA
    v
Stealth Wallet (fresh Keypair)
    |
    User imports private key to Phantom

Your wallet sends SOL to the relayer. The relayer executes the Jupiter swap from its own keypair — your address never appears in the swap transaction. Swapped tokens are transferred to a freshly generated stealth wallet. Import the private key to Phantom to access your tokens.

No custom Solana program required. No database. localStorage for stealth wallet data, server-side relayer for swap execution.

Getting Started

Prerequisites

• Node.js 18+
• A Solana wallet (Phantom or Solflare)
• A funded relayer wallet (~0.02 SOL for gas)

1. Install

cd app
npm install

2. Configure Environment

Edit app/.env:

ANON_API_KEY=<your anoncoin api key>
NEXT_PUBLIC_SOLANA_RPC_URL=https://api.mainnet-beta.solana.com
NEXT_PUBLIC_RELAYER_ADDRESS=<relayer wallet public key>
RELAYER_PRIVATE_KEY=<relayer wallet base58 private key>
OPENAI_API_KEY=<openai api key>

The relayer wallet needs ~0.003 SOL per swap for gas and ATA creation. With 0.02 SOL you get ~6 demo transactions.

3. Run

cd app
npm run dev

Open http://localhost:3000 and connect a Solana wallet on mainnet.

Usage

Anonymous Swap

1. Navigate to /swap
2. Enter the token mint address — AI risk analysis loads automatically
3. Enter SOL amount — live Jupiter quote appears
4. Click "Swap Anonymously" — approve the SOL deposit to relayer
5. Relayer executes the swap and transfers tokens to a stealth wallet
6. Save the stealth wallet to the wallet manager

Stealth Token Launch

1. Navigate to /launch
2. Fill in token details (name, symbol, description, socials)
3. Configure pre-buy: total SOL and number of stealth wallets (1-5)
4. Approve the deposit — token creation and distributed pre-buys execute
5. All stealth wallet keys are displayed and can be saved to the manager

Wallet Manager

1. Navigate to /wallets
2. View all stealth wallets with live SOL and token balances
3. Actions: reveal/copy private key, sweep all assets, import external wallets
4. Follow the Phantom import instructions to access tokens in your mobile wallet

Privacy Model

What's public on-chain	What's private
User deposits SOL to relayer address	What the SOL was used to buy
Relayer swaps on Jupiter	Who initiated the swap
Stealth wallet receives tokens	Link between user wallet and stealth wallet

An observer sees: wallet A sent SOL to relayer R. Separately, relayer R swapped SOL for token T. Separately, a new wallet S received token T. They cannot prove A and S belong to the same person.
