Why Rexa?

Built from the ground up for users who demand absolute privacy without compromising on speed or usability.

Zero-Knowledge Proofs

Transactions are validated without revealing sender, receiver, or amount. True cryptographic privacy.

Sub-Second Finality

Private transactions settle in under 1 second. No more waiting for block confirmations.

Multi-Chain

Ethereum, Solana, BSC, Polygon, Arbitrum, and more. One interface, all chains.

Non-Custodial

You control your keys. Always. We never have access to your funds or data.

Decentralized

No central servers. No single point of failure. Pure peer-to-peer privacy.

Low Fees

Private transactions from $0.01. Privacy shouldn't cost a premium.

Core Features

Everything you need for private, secure transactions in one powerful platform.

Stealth Addresses

Every transaction generates a unique one-time address. No address reuse, no traceability.

Ring Signatures

Your signature is hidden among a group of decoys. Impossible to identify the real signer.

Private Swaps

Swap tokens without revealing your trading history or positions. MEV-resistant by design.

Shielded Pools

Deposit to a shared pool. Withdraw to a fresh address. Break the on-chain link completely.

Cross-Chain Bridges

Move assets between chains privately. No public bridge transactions linking your wallets.

Mobile Ready

Full functionality on mobile. Send private transactions from anywhere, anytime.

API Access

Build privacy into your dApp. Simple REST API for integrating private transactions.

Analytics Dashboard

Track your private portfolio. Encrypted analytics that only you can decrypt.

Emergency Pause

Instantly freeze all outgoing transactions. Security when you need it most.

Send Private Transaction

Transfer assets anonymously with military-grade encryption.

How It Works

Your transaction data...
↓
Encrypted with zero-knowledge proof...
↓
Broadcast to network. Verified without revealing data.

Security Architecture

Multi-layered security designed to protect your privacy at every level.

End-to-End Encryption

All data encrypted with AES-256 before leaving your device. We never see plaintext.

Zero-Knowledge Proofs

zk-SNARKs ensure transaction validity without exposing any sensitive information.

Decentralized Network

No single point of failure. Distributed relay nodes ensure censorship resistance.

Audited Smart Contracts

All contracts audited by Trail of Bits, OpenZeppelin, and CertiK.

Bug Bounty Program

Up to $500,000 for critical vulnerabilities. Continuous security research.

Formal Verification

Core protocols mathematically proven correct. No room for exploits.

Developer Documentation

Integrate private transactions into your application.

Quick Start

Get up and running with Rexa private transactions in under 5 minutes.

1. Install the SDK

npm install @rexa/sdk

2. Initialize the Client

import { RexaClient } from '@rexa/sdk'; const client = new RexaClient({ network: 'mainnet', chain: 'ethereum' });

3. Send a Private Transaction

const tx = await client.sendPrivate({ to: '0x...', amount: '1.5', token: 'ETH', privacyLevel: 'high' }); console.log(tx.hash); // Private tx hash

Frequently Asked Questions

Everything you need to know about Rexa System.

What makes Rexa different from other privacy solutions? ▼
Rexa combines zero-knowledge proofs, ring signatures, and stealth addresses in a single protocol. Unlike mixers that rely on centralized relayers, Rexa is fully decentralized with sub-second finality and cross-chain support.
Is Rexa compliant with regulations? ▼
Rexa provides privacy tools for legitimate use. We support compliance through optional view keys that allow users to disclose transaction history to auditors or regulators when required, while maintaining privacy by default.
How much do private transactions cost? ▼
Private transactions start from $0.01 on L2s and Solana. Ethereum mainnet transactions typically cost $2-5 depending on network congestion. Fees are paid in REXA tokens with a 20% discount.
Can I recover my funds if I lose my wallet? ▼
Rexa supports social recovery through trusted guardians. You can designate friends or hardware wallets as recovery contacts. Without recovery setup, lost keys mean lost funds — we have no backdoor access.
Which wallets are supported? ▼
Rexa supports MetaMask, Phantom, Rabby, Rainbow, and WalletConnect-compatible wallets. Mobile support includes Trust Wallet and Coinbase Wallet through our native apps.
How does the REXA token work? ▼
REXA is used for transaction fee discounts, staking rewards, and governance voting. Stakers earn a share of protocol fees and can participate in DAO decisions about protocol upgrades and treasury allocation.
