Onchain Privacy Tools

Arcium is a decentralized confidential computing network that enables trustless encrypted computations over encrypted data using Multi-Party Computation. Built on Solana, it provides developers with MXEs—configurable MPC execution environments—and Arcis, a Rust-based DSL, to build privacy-preserving applications for AI, DeFi, and DePIN without exposing underlying data.

BChat is an end-to-end encrypted messaging application built on the Beldex network that requires no phone number or email to register. Messages are routed through decentralized Beldex nodes to minimize metadata exposure, enabling private cross-device communication without central servers or identity requirements.

Beldex Browser is a privacy-first, ad-free web browser integrated with BelNet for IP masking and protection from online tracking. It supports MNApps and BNS domains, enabling access to censorship-resistant applications on the Beldex network. Built for private everyday browsing without ads or third-party data collection.

Beldex is a privacy blockchain network that combines Monero-based cryptography with a decentralized masternode infrastructure to enable private digital transactions and applications. The BDX coin powers transactions, staking, and network utilities across the ecosystem, which includes encrypted messaging, a decentralized VPN, a privacy browser, and a naming service.

BelNet is a decentralized VPN built on an onion-routing protocol that masks IP addresses and browsing activity by routing traffic through distributed Beldex nodes. It prevents centralized tracking and provides a private gateway to the internet, and is natively integrated into the Beldex Browser.

BNS (Beldex Name Service) is a decentralized naming system that maps human-readable names to wallet addresses, BChat IDs, and BelNet-hosted web applications within the Beldex ecosystem. By replacing long cryptographic identifiers with memorable names, BNS simplifies private transactions, messaging, and digital identity management across all Beldex network products.

GhostWareOS is a full-stack privacy layer for Solana that anonymizes user activity across payments, communications, and identity. Using zero-knowledge proofs and HPKE encryption, it provides GhostPay for private transactions hiding sender, receiver, and amount; GhostMask for generating communication aliases; GhostRelay for stateless encrypted messaging; and GhostScrub for revoking risky on-chain token approvals. The GHOST token redistributes 100% of protocol fee revenue to holders.

MagicBlock is a real-time infrastructure layer for Solana that enables low-latency, fee-free, and privacy-preserving application experiences via Ephemeral Rollups. Its Private Ephemeral Rollup (PER) uses Trusted Execution Environments (Intel TDX) for privacy-preserving computation without bridging assets off Solana. Designed for games, DeFi, and high-frequency use cases, it achieves sub-50ms end-to-end latency with 1ms block times while keeping applications fully composable with Solana's existing state and programs.

Nillion is a decentralized secure computation network that enables privacy-preserving storage and processing of sensitive data without decryption. Using Multi-Party Computation, Homomorphic Encryption, and Trusted Execution Environments, it offers nilDB for encrypted distributed storage, nilCC for private compute in TEEs, and nilAI for confidential LLM inference — targeting AI, DeFi, and identity applications where data privacy is critical.

Turbine Cash is a non-custodial privacy pool on Solana that enables private token transfers using zero-knowledge proofs. Users deposit SOL, USDC, or USDT into a Merkle-tree-based pool, wait to build an anonymity set, then withdraw to any address via a ZK proof submitted through a relayer — severing the on-chain link between sender and recipient. OFAC-compliant and supports cross-token withdrawals via Jupiter swap integration.

Loyal is an open-source, privacy-preserving AI assistant built on Solana. It uses Trusted Execution Environments (TEE), end-to-end encryption, and AES to keep conversations and documents confidential. Users can summarize Telegram chats, process sensitive documents, and automate on-chain workflows — all without exposing data to third parties. Loyal follows a wallet-based data ownership model where users retain full control over their information.

Stealf is a Solana-based neo-banking platform that combines regulated fiat banking with private cryptocurrency transactions. Using Arcium's multi-party computation (MPC) encryption, Stealf enables users to hold crypto, spend cash via compliant card payments, and move funds between wallets without exposing on-chain activity. Its dual-layer architecture separates traditional banking compliance from encrypted blockchain execution, offering self-custody and shielded transfers.

Vanish is a private trading platform on Solana that uses shielded transaction routing and zero-knowledge primitives to protect traders from front-running, copy-trading, and alpha leakage. By decoupling trades from user wallets through smart routing across shielded liquidity sources, Vanish enables compliant private swaps for any SPL token. Its Integrity Framework ensures regulatory compliance via multi-layer screening and address logic rules.

anonme.sh is an offline-first cryptocurrency wallet and messaging platform built on Solana. It enables private transactions and encrypted communications without requiring internet connectivity, using a peer-to-peer mesh relay layer to forward AES-256-GCM encrypted transactions through nearby devices. Users can generate wallets, create and sign swaps offline, and broadcast when connectivity is available — all without phone numbers or persistent identity.

NOCtura is a compliant privacy protocol and dual-mode wallet on Solana that lets users switch between Transparent Mode for standard DeFi composability and Shielded Mode for private transfers where sender, receiver, and amount are hidden using zero-knowledge proofs. Its selective disclosure engine — View Keys and Audit Tokens — enables scoped, revocable verification for institutional compliance without exposing full transaction history.

Subly is a privacy-first PayFi protocol that converts DeFi yield into automatic subscription payments. Users deposit USDC once, and earned yield covers recurring costs without exposing payment details. Powered by Arcium's Cerberus multi-party computation (MPC), Subly shields transaction data while enabling seamless payouts to merchants via PayPal, eliminating the need for users to manage individual payment obligations.
